The Mexican drug war (also known as the Mexican war on drugs; Spanish: Guerra contra el narcotráfico en México, shortened to and commonly known inside Mexico as the war against the narco; Spanish: Guerra contra el narco)^[30] is an ongoing asymmetric^[31][32] armed conflict between the Mexican government and various drug trafficking syndicates. When the Mexican military intervened in 2006, the government's main objective was to reduce drug-related violence.^[33] The Mexican government has asserted that their primary focus is dismantling the cartels and preventing drug trafficking. The conflict has been described as the Mexican theater of the global war on drugs, as led by the United States federal government.^[34]

Violence escalated after the arrest of Miguel Ángel Félix Gallardo in 1989. He was the leader and the co-founder of the first major Mexican drug cartel; the Guadalajara Cartel, an alliance of the current existing cartels (which included the Sinaloa Cartel, the Juarez Cartel, the Tijuana Cartel, and the Sonora Cartel with Aldair Mariano as the leader). After his arrest, the alliance broke and high-ranking members formed their own cartels, fighting for control of territory and trafficking routes.

Although Mexican drug trafficking organizations have existed for several decades, their influence increased^[35][36] after the demise of the Colombian Cali and Medellín cartels in the 1990s. By 2007, Mexican drug cartels controlled 90% of the cocaine entering the United States.^[37][38] Arrests of key cartel leaders, particularly in the Tijuana and Gulf cartels, have led to increasing drug violence as cartels fight for control of the trafficking routes into the United States.^[39][40][41]

Federal law enforcement has been reorganized at least five times since 1982 in various attempts to control corruption and reduce cartel violence. During the same period, there have been at least four elite special forces created as new, corruption-free soldiers who could do battle with Mexico's endemic bribery system.^[42] Analysts estimate that wholesale earnings from illicit drug sales range from $13.6 to $49.4 billion annually.^[37][43][44] The U.S. Congress passed legislation in late June 2008 to provide Mexico with US$1.6 billion for the Mérida Initiative as well as technical advice to strengthen the national justice systems. By the end of President Felipe Calderón's administration (December 1, 2006 – November 30, 2012), the official death toll of the Mexican drug war was at least 60,000.^[45] Estimates set the death toll above 120,000 killed by 2013, not including 27,000 missing.^[46][47] Since taking office in 2018, President Andrés Manuel López Obrador declared that the war was over. His comment was criticized, as the homicide rate remains high.

Due to its location, Mexico has long been used as a staging and transshipment point for narcotics and contraband between Latin America and U.S. markets. Mexican bootleggers supplied alcohol to the United States' gangsters throughout Prohibition in the United States,^[38] and the onset of the illegal drug trade with the U.S. began when prohibition came to an end in 1933.^[38] Near the end of the 1960s, Mexicans started to smuggle drugs on a major scale.^[38]

In the 1960s and 1970s, Mexico was part of both Operation Intercept^[48] and Operation Condor,^[49] developed between 1975 and 1978, with the pretext to fight against the cultivation of opium and marijuana in the "Golden Triangle", particularly in Sinaloa.^[50]

The operation, commanded by General José Hernández Toledo,^[51] was a failure with no major drug lord captures, and reported abuse and repression in rural zones.^[52]

During the 1970s and early 1980s, Colombia's Pablo Escobar was the main exporter of cocaine and dealt with organized criminal networks all over the world. While Escobar's Medellin Cartel and the Cali Cartel would manufacture the products, Miguel Ángel Félix Gallardo's Guadalajara Cartel would oversee distribution. When enforcement efforts intensified in South Florida and the Caribbean, the Colombian organizations formed partnerships with the Mexico-based traffickers to transport cocaine by land through Mexico into the United States.^[53]

This was easily accomplished because Mexico had long been a major source of heroin and cannabis, and drug traffickers from Mexico had already established an infrastructure that stood ready to serve the Colombia-based traffickers. By the mid-1980s, the organizations from Mexico were well-established and reliable transporters of Colombian cocaine. At first, the Mexican gangs were paid in cash for their transportation services, but in the late 1980s, the Mexican transport organizations and the Colombian drug traffickers settled on a payment-in-product arrangement.^[54]

Transporters from Mexico usually were given 35% to 50% of each cocaine shipment. This arrangement meant that organizations from Mexico became involved in the distribution, as well as the transportation of cocaine, and became formidable traffickers in their own right. In recent years, the Sinaloa Cartel and the Gulf Cartel have taken over trafficking cocaine from Colombia to the worldwide markets.^[54]

The balance of power between the various Mexican cartels continually shifts as new organizations emerge and older ones weaken and collapse. A disruption in the system, such as the arrests or deaths of cartel leaders, generates bloodshed as rivals move in to exploit the power vacuum.^[55] Leadership vacuums are sometimes created by law enforcement successes against a particular cartel, so cartels often will attempt to pit law enforcement against one another, either by bribing corrupt officials to take action against a rival or by leaking intelligence about a rival's operations to the Mexican or U.S. government's Drug Enforcement Administration (DEA).^[55]

While many factors have contributed to the escalating violence, security analysts in Mexico City trace the origins of the rising scourge to the unraveling of a longtime implicit arrangement between narcotics traffickers and governments controlled by the Institutional Revolutionary Party (PRI), which began to lose its grip on political power in the late 1980s.^[56]

The fighting between rival drug cartels began in earnest after the 1989 arrest of Félix Gallardo, who ran the cocaine business in Mexico.^[57] There was a lull in the fighting during the late 1990s but the violence has steadily worsened since 2000.

According to researchers, as of 2023 there are an estimate of 175,000 people working for the drug cartel.^[58] The head of the U.S drug enforcement reported that there are an estimate of 45,000 members associates and brokers spread over more than 100 countries working under the Sinaloa cartel and the Jalisco New Generation cartel.^[58]

The dominant PRI party ruled Mexico for around 70 years until 2000. During this time, drug cartels expanded their power and political influence, and anti-drug operations focused mainly on destroying marijuana and opium crops in mountainous regions. There were no large-scale high-profile military operations against their core structures in urban areas until the 2000 Mexican election, when the right-wing PAN party gained the presidency and started a crackdown on cartels in their own turf.

In 2000, Vicente Fox, from the right-wing PAN party, became the first Mexican president since the Mexican Revolution not to be from the PRI; his presidency passed with relative peace, having a crime index not too different from that of previous administrations, and Mexican public opinion was mainly optimistic with the regime change, with Mexico showing a decline in homicide rates from 2000 to 2007.^[59] One of the Fox's administration's strongest criticisms arose from its management of the peasant unrest in San Salvador Atenco.

Los Zetas, the armed wing of the Gulf Cartel, based in Nuevo Laredo, escalated violence to unprecedented levels in the summer of 2003 through gruesome violence and military-like tactics against the Sinaloa Cartel.^[60] Los Zetas also instilled terror against journalists and civilians of Nuevo Laredo. This set a new precedent which cartels later mimicked.^[61] All these activities by Mexican criminal organizations were not widely reported by the Mexican media, although key conflicts took place, including the Sinaloa Cartel attacks and advance on the Gulf Cartel's main regions in Tamaulipas.

It is estimated that in the first eight months of 2005, about 110 people died in Nuevo Laredo, Tamaulipas as a result of the fighting between the Gulf and Sinaloa cartels.^[62] The same year, there was another surge in violence in the state of Michoacán as La Familia Michoacana drug cartel established itself, after splintering from its former allies, the Gulf Cartel and Los Zetas.

On December 11, 2006, newly elected President Felipe Calderón, from the PAN party, dispatched 6,500 Mexican Army soldiers to Michoacán, his home state, to end drug violence. This action is regarded as the first major deployment of government forces against cartels, and is generally viewed as the starting point of the Mexican drug war.^[63] As time passed, Calderón continued to escalate his anti-drug campaign. By 2008, there were about 45,000 troops involved along with state and federal police forces.^[64]

The government was initially successful in detaining drug lords. Drug-related violence spiked markedly in contested areas along the U.S. border such as Ciudad Juárez, Tijuana, and Matamoros. Some analysts, including U.S. Ambassador in Mexico Carlos Pascual, argued that this rise in violence was a direct result of Felipe Calderón's military measures.^[65] Since Calderón launched his military strategy against organized crime, there was an alarming increase in violent deaths related to organized crime: more than 15,000 people died in suspected drug cartel attacks since it was launched at the end of 2006.^[65] More than 5,000 people were murdered in Mexico in 2008,^[66] followed by 9,600 murders in 2009; 2010 saw more than 15,000 homicides across the country.^[67]

By the end of Calderón's presidency his administration statistics claimed that, during his 6-year term, 50,000 drug related homicides occurred.^[68] Outside sources claimed more than 120,000 murders happened in the same period as result of his militaristic anti-drug policy.^[69]

In 2012, newly elected president Enrique Peña Nieto, from the PRI party, emphasized that he did not support the involvement of armed American agents in Mexico and was only interested in training Mexican forces in counter-insurgency tactics.^[70] Peña Nieto stated that he planned to deescalate the conflict, focusing in lowering criminal violence rates, as opposed to the previous policy of attacking drug-trafficking organizations by arresting or killing the most-wanted drug lords and intercepting their shipments.^[71]

In the first 14 months of his administration, between December 2012 and January 2014, 23,640 people died in the conflict.^[72]

In 2013 Mexico saw the rise of the controversial Grupos de Autodefensa Comunitaria (self-defence groups) in southern Mexico, para-military groups led by land-owners, ranchers and other rural inhabitants that took up arms against the criminal groups that wanted to impose dominance in their towns, entering a new phase in the Mexican war on drugs.^[73] This strategy, allegedly proposed by General Óscar Naranjo, Peña Nieto's security advisor from Colombia,^[74] crumbled when autodefensas started to have internal organization struggles and disagreements with the government, as well as infiltration by criminal elements, that deprived the government forces the ability to distinguish between armed-civilian convoys and drug-cartel convoys, forcing Peña Nieto's administration to distance from them.^[75]

Peña Nieto's handling of the 2014 Iguala mass kidnapping and the 2015 escape of drug lord Joaquín "El Chapo" Guzmán from the Altiplano maximum security prison sparked international criticism.^[76][77]

A great part of Peña Nieto's strategy consisted in making the Mexican Interior Ministry solely responsible for public security and the creation of a national military level police force called the National Gendarmerie. In December 2017, the Law of Internal Security was passed by legislation but was met with criticism, especially from the National Human Rights Commission, accusing it gave the President a blank check.^{[78][79][80][81]}

Andrés Manuel López Obrador, the President from the Center-left National Regeneration Movement party, took office on December 1, 2018. One of his campaign promises was a controversial "strategy for peace", which would give amnesty to Mexicans involved in drug production and trafficking as a way to stop the drug trade and the resulting turf violence.^[82] His aides explained that the plan was not to pardon real criminals, like violent drug cartel members, but to prevent other people from following that path, especially low-income people, farmers forced into drug cultivation by cartels, and young people that may end up in jail for drug possession.^[83] Obrador pointed out that the past approaches failed because they were based on misunderstanding the core problem. According to him, the underlying issue was Mexico's great social disparities which previous governments' economic policies did not reduce.

For law enforcement, he promised to hold a referendum for the creation of a temporary national guard, merging elite parts of the Federal police, Military police, Navy, Chief of Staff's Guard and other top Mexican Security agencies, intending to finally give a legal framework to the military grade forces that have been doing police work in the last years.^[84] He promised not to use arms to suppress the people, and made an announcement to free political prisoners. His approach is to pay more attention to the victims of violent crime and he wants to revisit two previously taken strategies.^[85] In 2019, the promised Mexican National Guard was created.^[86]

Despite the new government's planned strategy changes,^[87] during the first two months of the new presidency the violence between drug trafficking organizations sustained the same levels as previous years.^[88] On July 15, 2022 authorities captured Rafael Caro-Quintero, a former leader of the Guadalajara cartel, but lost fourteen soldiers in an aircraft crash in the remote mountains near Sinaloa's border with Chihuahua.^[89]

On January 30, 2019, Obrador declared the end of the Mexican war on drugs,^[90] stating that he would now focus on reducing spending,^[91] and direct its military and police efforts primarily on stopping the armed gasoline theft rings —locally called huachicoleros— that had been stealing more than 70 thousand barrels of oil, diesel and gasoline daily,^[92][93][94] costing the Mexican state-owned company Pemex around 3 billion dollars every year.^[95]

On October 17, 2019, based on an extradition request sent to Mexico by a Washington, D.C. judge^[96] a failed operation to capture alleged kingpin Ovidio Guzmán López was carried by the Mexican National Guard, in which fourteen people died (mostly from the armed forces and cartel enforcers and one civilian bystander).^[97] Guzmán was released^[98] after approximately 700 cartel enforcers,^[99] armed with .50 caliber rifles, Rocket-propelled grenades (RPGs) and 40 mm grenades took multiple hostages, including the housing unit where military families live in Culiacan.^[100] The cartels used burning vehicles to block roads, a tactic taken from militant protesters, with the event described as a mass insurrection.^[101] Obrador defended the decision to release Ovidio Guzmán, arguing it prevented further loss of life,^[102] and insisted that he wants to avoid more massacres.^[103] He further stated that the capture of one drug smuggler cannot be more valuable than the lives of innocent civilians,^[104] and that even though they underestimated the cartel's manpower and ability to respond^[105] the criminal process against Ovidio is still ongoing,^[106] During 2019, the federal forces deployed 8,000 troops and police reinforcements to restore peace in Culiacan.^[99]

This strategy of avoiding armed confrontations while drug organizations have continued violent altercations has been controversial.^{[107][88][108][109]} One of the strongest critics of the new strategy and a firm proponent of continuing the armed struggle is former President Felipe Calderón, who originally started the military operations against traffickers in 2006.^[110][111] Calderón's militaristic strategy to capture cartel heads has also been criticised by local and foreign experts, as well as by multiple media outlets.^{[112][113][114]}

President López Obrador, known for his strong criticism of the previous administrations' approach to public security through militarization, campaigned on the promise of removing the military from the streets and returning them to the barracks. However, under the López Obrador administration, deployments and military expenditures have reached unprecedented levels. The current number of soldiers deployed for security duties is 76% higher than during Felipe Calderón's presidency, whom López Obrador holds responsible for the militarization of the drug war. Consequently, defense spending has surged by 87% between 2012, Calderón's last year in office, and 2022.^[115]

Although the number of deployed soldiers is higher, available data indicates that they assume a more restrained role. They engage in fewer confrontations, seize fewer firearms, and prioritize non-confrontational strategies to deter criminals.^[116] This has resulted in lower seizures of weapons and fewer arrests of alleged criminals.^[117] Additionally, President López Obrador has broadened their duties, such as overseeing vaccine distribution and addressing irregular migration flows.

The U.S. State Department estimates that 90 percent of cocaine entering the United States is produced in Colombia^[118] (followed by Bolivia and Peru)^[119] and that the main transit route is through Mexico.^[37] Drug cartels in Mexico control approximately 70% of the foreign narcotics flow into the United States.^[120]

Mexican cartels distribute Asian^[121] methamphetamine to the United States.^[37] It is believed that almost half the cartels' revenues come from cannabis.^[122] Cocaine, heroin, and increasingly methamphetamine are also traded.^[123]

Although Mexico accounts for only a small share of worldwide heroin production, it supplies a large share of the heroin distributed in the United States.^[124]

Since 2003 Mexican cartels have used the dense, isolated portions of U.S. federal and state parks and forests to grow marijuana under the canopy of thick trees. Billions of dollars’ worth of marijuana has been produced annually on U.S. soil. "In 2006, federal and state authorities seized over 550,000 marijuana plants worth an estimated 1 billion dollars in Kentucky's remote Appalachian counties". Cartels profited from marijuana growing operations from Arkansas to Hawaii.^[125]

A 2018 study found that the reduction in drugs from Colombia contributed to Mexican drug violence. The study estimated, "between 2006 and 2009 the decline in cocaine supply from Colombia could account for 10%–14% of the increase in violence in Mexico."^[126]

Illicit drug use in Mexico is low compared to the United States, but is on the rise.^[127] With Mexico's increased role in the trafficking and production of illicit drugs, the availability of drugs has slowly increased locally since the 1980s. In the decades before this period, consumption was not generalized – reportedly occurring mainly among persons of high socioeconomic status, intellectuals and artists.^[128]

As the United States of America is the world's largest consumer of cocaine,^[129] as well as of other illegal drugs,^[130] their demand is what motivates the drug business, and the main goal of Mexican cartels is to introduce narcotics into the U.S.

The export rate of cocaine to the U.S. has decreased following stricter border control measures in response to the September 11 attacks.^[128][131]

This has led to a surplus of cocaine which has resulted in local Mexican dealers attempting to offload extra narcotics along trafficking routes, especially in border areas popular among North American tourists.^{[citation needed]}

Drug shipments are often delayed in Mexican border towns before delivery to the U.S., which has forced drug traffickers to increase prices to account for transportation costs of products across international borders, making it a more profitable business for the drug lords, and has likely contributed to the increased rates of local drug consumption.^[128]

With increased cocaine use, there has been a parallel rise in demand for drug user treatment in Mexico.^[128]

One of the main factors driving the Mexican drug war is widespread poverty. From 2004 to 2008 the portion of the population who received less than half of the median income rose from 17% to 21% and the proportion of population living in extreme or moderate poverty rose from 35 to 46% (52 million persons) between 2006 and 2010.^{[132][133][134]}

Among the OECD countries, Mexico has the second highest degree of economic disparity between the extremely poor and extremely rich.^[135] The bottom ten percent in the income hierarchy disposes of 1.36% of the country's resources, whereas the upper ten percent dispose of almost 36%. OECD also notes that Mexico's budgeted expenses for poverty alleviation and social development is only about a third of the OECD average.^[133]

In 2012 it was estimated that Mexican cartels employed over 450,000 people directly and a further 3.2 million people's livelihoods depended on various parts of the drug trade.^[136] In cities such as Ciudad Juárez, up to 60% of the economy depended on illegal sources of income.^[137]

A problem that goes hand in hand with poverty in Mexico is the level of schooling.^[138][139] In the 1960s, when Mexican narcotic smugglers started to smuggle drugs on a major scale,^[38] only 5.6% of the Mexican population had more than six years of schooling.^[140]

More recently, researchers from the World Economic Forum have noted that despite the Mexican economy ranking 31st out of 134 economies for investment in education (5.3% of its GDP), as of 2009, the nation's primary education system is ranked only 116th, thereby suggesting "that the problem is not how much but rather how resources are invested".^[141] The WEF further explained: "The powerful teachers union, the SNTE, the largest labor union in Latin America, has been in large part responsible for blocking reforms that would increase the quality of spending and help ensure equal access to education."^[how?] The result of the high levels of poverty, lack of well paid jobs, government corruption, and the systemic failure of Mexico's schools has been the appearance of ninis, a youth underclass of school-dropouts who neither work nor study, who might have ended up as combatants on behalf of the cartels.^{[142][dubious – discuss]}

Teachers' unions have opposed reforms that propose their testing and grading on their students' performance^[143] with standardized tests that do not take into account the socioeconomic differences between middle class urban schools and under-equipped poor rural schools, which has an important effect on the students performance.^{[144][145][146][147]} Also, teachers unions have argued the legislation is ambiguous, focuses exclusively on teachers, without evaluating the Education Ministry, and will allow more abuses and political corruption.^{[148][149][150][151][152]}

The birth of most Mexican drug cartels is traced to former Mexican Judicial Federal Police agent Miguel Ángel Félix Gallardo (Spanish: El Padrino, lit. 'The Godfather'), who founded the Guadalajara Cartel in 1980 and controlled most of the illegal drug trade in Mexico and the trafficking corridors across the Mexico–U.S. border along with Juan García Ábrego throughout the 1980s.^[153] He started off by smuggling marijuana and opium into the U.S., and was the first Mexican drug chief to link up with Colombia's cocaine cartels in the 1980s. Through his connections, Félix Gallardo became the person at the forefront of the Medellín Cartel, which was run by Pablo Escobar.^[154] This was accomplished because Félix Gallardo had already established a marijuana trafficking infrastructure that stood ready to serve the Colombia-based cocaine traffickers.

There were no other cartels at that time in Mexico.^{[154]: 41 [154]} He oversaw operations with his cronies and the politicians who sold him protection.^[154] The Guadalajara Cartel suffered a major blow in 1985 when the group's co-founder Rafael Caro Quintero was captured, and later convicted, for the murder of DEA agent Enrique "Kiki" Camarena.^[155][156] Félix Gallardo then kept a low profile and in 1987 he moved with his family to Guadalajara. According to Peter Dale Scott, the Guadalajara Cartel prospered largely because it enjoyed the protection of the Dirección Federal de Seguridad (DFS), under its chief Miguel Nazar Haro.^[157]

Félix Gallardo was arrested on April 8, 1989.^[158] He then divested the trade he controlled as it would be more efficient and less likely to be brought down in one law enforcement swoop.^[154]: 47 He sent his lawyer to convene the nation's top drug traffickers at a house in Acapulco where he designated plazas or territories.^[154][159]

The Tijuana route would go to his nephews the Arellano Felix brothers. The Ciudad Juárez route would go to the Carrillo Fuentes family. Miguel Caro Quintero would run the Sonora corridor. Meanwhile, Joaquín Guzmán Loera and Ismael Zambada García would take over Pacific coast operations, becoming the Sinaloa Cartel. Guzmán and Zambada brought veteran Héctor Luis Palma Salazar back into the fold. The control of the Matamoros, Tamaulipas corridor—then becoming the Gulf Cartel—would be left undisturbed to its founder Juan García Ábrego, who was not a party to the 1989 pact.^[160]

Félix Gallardo still planned to oversee national operations, as he maintained important connections, but he would no longer control all details of the business.^[154] When he was transferred to a high-security prison in 1993, he lost any remaining control over the other drug lords.^[161]

The Sinaloa Cartel began to contest the Gulf Cartel's domination of the coveted southwest Texas corridor following the arrest of Gulf Cartel leader Osiel Cárdenas in March 2003. The "Federation" was the result of a 2006 accord between several groups located in the Pacific state of Sinaloa. The cartel was led by Joaquín "El Chapo" Guzmán, who was Mexico's most-wanted drug trafficker with an estimated net worth of U.S. $1 billion. This made him the 1140th richest man in the world and the 55th most powerful, according to his Forbes magazine profile.^[162] He was arrested and escaped in July 2015,^[163][164] and re-arrested in January 2016.^[165] In February 2010, new alliances were formed against Los Zetas and Beltrán-Leyva Cartel.^[166]

The Sinaloa Cartel fought the Juárez Cartel in a long and bloody battle for control over drug trafficking routes in and around the northern city of Ciudad Juárez. The battle eventually resulted in defeat for the Juárez Cartel, resulting in the deaths of between 5,000 and 12,000 people.^[167] During the war for the turf in Ciudad Juárez the Sinaloa Cartel used several gangs (e.g. Los Mexicles, the Artistas Asesinos and Gente Nueva) to attack the Juárez Cartel.^[167] The Juárez Cartel similarly used gangs such as La Línea and the Barrio Azteca to fight the Sinaloa Cartel.^[167]

As of May 2010, numerous reports by Mexican and U.S. media stated that Sinaloa had infiltrated the Mexican federal government and military, and colluded with it to destroy the other cartels.^[168][169] The Colima, Sonora and Milenio Cartels are now branches of the Sinaloa Cartel.^[170]

Joaquín "El Chapo" Guzmán was arrested on January 8, 2016, and extradited to the United States a year later. On February 4, 2019, in Brooklyn, NY, he was found guilty of ten counts of drug trafficking and sentenced to life imprisonment. Guzman unsuccessfully attempted to convince prosecutors that he has assumed charges on behalf of Ismael "El Mayo" Zambada^[171] "El Chapo" alleged that he had paid former presidents Enrique Peña Nieto and Felipe Calderón bribes, which was quickly denied by both men.^[172] In March 2019, El Chapo's successor, Ismael Zambada García, alias "El Mayo," was reported to be Mexico's "last Capo" and even more feared than his closest rival Nemesio Oseguera Cervantes, alias "El Mencho," who serves as leader of the Jalisco Cartel New Generation.^[173]

On January 5, 2023 the arrest of Ovidio Guzmán, son of jailed drug lord Joaquín 'El Chapo' Guzmán, sparked a wave of violence in the state of Sinaloa. The violence prompted the Mexican military to launch a series of armed raids using planes and helicopters to attack Sinaloa cartel members.^[174]

The Beltrán-Leyva Cartel was a Mexican drug cartel and organized crime syndicate founded by the four Beltrán Leyva brothers: Marcos Arturo, Carlos, Alfredo and Héctor.^{[175][176][177][178]} In 2004 and 2005, Arturo Beltrán Leyva led powerful groups of assassins to fight for trade routes in northeastern Mexico for the Sinaloa Cartel. Through corruption or intimidation, the Beltrán-Leyva Cartel infiltrated Mexico's political,^[179] judicial^[180] and police institutions to feed classified information about anti-drug operations,^[181][182] and even infiltrated the Interpol office in Mexico.^[183]

Following the December 2009 death of the cartel's leader Arturo Beltrán Leyva by Mexican Marines the cartel entered into an internal power struggle between Arturo's brother, Héctor Beltrán Leyva, and Arturo's top enforcer Edgar Valdez Villarreal.^[6] Meanwhile, the cartel continued to dissolve with factions such as the South Pacific Cartel, La Mano Con Ojos, Independent Cartel of Acapulco, and La Barredora forming and the latter two cartels starting yet another intra-Beltrán Leyva Cartel conflict.^[6]

The Mexican Federal Police considers the cartel to have been disbanded,^[184][185] and the last cartel leader, Héctor Beltrán Leyva, was captured in October 2014.^[186]

The Juárez Cartel controls one of the primary transportation routes for billions of dollars' worth of illegal drug shipments annually entering the United States from Mexico.^[187] Since 2007, the Juárez Cartel has been locked in a vicious battle with its former partner, the Sinaloa Cartel, for control of Ciudad Juárez. La Línea is a group of Mexican drug traffickers and corrupt Juárez and Chihuahua state police officers who work as the armed wing of the Juárez Cartel.^[188] Vicente Carrillo Fuentes headed the Juárez Cartel until his arrest in 2014.

Since 2011, the Juárez Cartel continues to weaken.^[189][190] It is present in the three main points of entry into El Paso, Texas. The Juárez Cartel is only a shadow of the organization it was a decade ago, and its weakness and inability to effectively fight against Sinaloa's advances in Juarez contributed to the lower death toll in Juarez in 2011.^[191]

The Tijuana Cartel, also known as the Arellano Félix Organization, was once among Mexico's most powerful.^[192] It is based in Tijuana, one of the most strategically important border towns in Mexico,^[193] and continues to export drugs even after weakening by an internal war in 2009. Due to infighting, arrests and the deaths of some of its top members, the Tijuana Cartel is a fraction of what it was in the 1990s and early 2000s, when it was considered one of the most potent and violent criminal organizations in Mexico by the police. After the arrest or assassination of various members of the Arellano Félix family, the cartel is currently allegedly headed by Edwin Huerta Nuño alias "El Flako".

The Gulf Cartel (CDG), based in Matamoros, Tamaulipas, has been one of Mexico's two dominant cartels in recent years. In the late 1990s, it hired a private mercenary army (an enforcer group now called Los Zetas), which in 2006 stepped up as a partner but, in February 2010, their partnership was dissolved, and both groups engaged in widespread violence across several border cities of Tamaulipas state,^[166][194] turning several border towns into "ghost towns".^[195]

The CDG was strong at the beginning of 2011, holding off several Zetas incursions into its territory. As the year progressed, internal divisions led to intra-cartel battles in Matamoros and Reynosa, Tamaulipas state. The infighting resulted in several arrests and deaths in Mexico and in the United States. The CDG has since broken apart, and it appears that one faction, known as Los Metros, has overpowered its rival Los Rojos faction and is now asserting its control over CDG operations.^[196]

The infighting has weakened the CDG, but the group seems to have maintained control of its primary plazas, or smuggling corridors, into the United States.^[196] The Mexican federal government has made notable successes in capturing the leadership of the Gulf Cartel. Osiel Cárdenas Guillén, his brothers Antonio Cárdenas Guillén, Mario Cárdenas Guillén, and Jorge Eduardo Costilla Sánchez have all been captured and incarcerated during Felipe Calderón's administration.

In 1999, Gulf Cartel's leader, Osiel Cárdenas Guillén, hired a group of 37 corrupt former elite military soldiers to work for him. These former Airmobile Special Forces Group (GAFE), and Amphibian Group of Special Forces (GANFE) soldiers became known as Los Zetas and began operating as a private army for the Gulf Cartel. During the early 2000s the Zetas were instrumental in the Gulf Cartel's domination of the drug trade in much of Mexico.

After the 2007 arrest and extradition of Osiel Cárdenas Guillén, the Zetas seized the opportunity to strike out on their own. Under the leadership of Heriberto Lazcano, the Zetas, numbering about 300, gradually set up their own independent drug, arms and human-trafficking networks.^[197] In 2008, Los Zetas made a deal with ex-Sinaloa cartel commanders, the Beltrán-Leyva brothers and since then, became rivals of their former employer/partner, the Gulf Cartel.^[166][198]

In early 2010 the Zetas made public their split from the Gulf Cartel and began a bloody war with the Gulf Cartel over control of northeast Mexico's drug trade routes.^[6] This war has resulted in the deaths of thousands of cartel members and suspected members. Furthermore, due to alliance structures, the Gulf Cartel-Los Zetas conflict drew in other cartels, namely the Sinaloa Cartel which fought the Zetas in 2010 and 2011.^[6]

The Zetas are notorious for targeting civilians, including the mass murder of 72 migrants in the San Fernando massacre.^[6]

The Zetas involved themselves in more than drug trafficking and have also been connected to human trafficking, pipeline trafficked oil theft, extortion, and trading unlicensed CDs.^[6] Their criminal network is said to reach far from Mexico including into Central America, the U.S. and Europe.^[6]

On July 15, 2013, the Mexican Navy arrested the top Zeta boss Miguel Treviño Morales.^[199]

In recent times, Los Zetas have experienced severe fragmentation and seen its influence diminish.^[200] As of December 2016, two subgroups calling themselves Los Zetas Grupo Bravo (Group Bravo) and Zetas Vieja Escuela (Old School Zetas) formed an alliance with the Gulf Cartel against a group known as El Cartel del Noreste (The Cartel of the Northeast).^[201]

La Familia Michoacana was a major Mexican drug cartel based in Michoacán between at least 2006 and 2011. It was formerly allied to the Gulf Cartel and Los Zetas, but split off and became an independent organization.^[202]

In 2009–10, a counter-narcotics offensive by Mexican and U.S. government agencies produced the arrest of at least 345 suspected La Familia members in the U.S., and the incorrectly presumed death^[205] of one of the cartel's founders, Nazario Moreno González, on December 9, 2010.^[6] The cartel then divided into the Knights Templar Cartel and a José de Jesús Méndez Vargas-led faction, which kept the name La Familia. Following the cartel's fragmentation in late 2010 and early 2011, the La Familia Cartel under Méndez Vargas fought the Knights Templar Cartel but on June 21, 2011, Méndez Vargas was arrested by Mexican authorities^[6] and in mid-2011 the attorney general in Mexico (PGR) stated that La Familia Cartel had been "exterminated",^[206] leaving only the splinter group, the Knights Templar Cartel.^[207][208]

In February 2010, La Familia forged an alliance with the Gulf Cartel against Los Zetas and Beltrán-Leyva Cartel.^[166]

The Knights Templar drug cartel (Spanish: Caballeros Templarios) was created in Michoacán in March 2011 after the death of the charismatic leader of La Familia Michoacana cartel, Nazario Moreno González.^[209] The Cartel is headed by Enrique Plancarte Solís and Servando Gómez Martínez who formed the Knights Templar due to differences with José de Jesús Méndez Vargas, who had assumed leadership of La Familia Michoacana.^[210]

After the emergence of the Knights Templar, sizable battles flared up during the spring and summer months between the Knights Templar and La Familia.^[6] The organization has grown from a splinter group to a dominant force over La Familia, and at the end of 2011, following the arrest of José de Jesús "El Chango" Méndez Vargas, leader of La Familia, the cartel appeared to have taken over the bulk of La Familia's operations in Mexico and the U.S.^[6] In 2011 the Knights Templar appeared to have aligned with the Sinaloa Federation in an effort to root out the remnants of La Familia and to prevent Los Zetas from gaining a more substantial foothold in the Michoacán region of central Mexico.^[211][212]

Alliances or agreements between drug cartels have been shown to be fragile, tense and temporary. Mexican drug cartels have increased their co-operation with U.S. street and prison gangs to expand their distribution networks within the U.S.^[44] On March 31, 2014, Enrique Plancarte Solís, a high-ranking leader in the cartel, was killed by the Mexican Navy.

On September 6, 2016, a Mexican police helicopter was shot down by a gang, killing four people. The police were conducting an operation against criminal groups and drug cartels in Apatzingán, including the Knights Templar Cartel.^[213]

The Jalisco New Generation Cartel (Spanish: Cártel de Jalisco Nueva Generación, CJNG, Los Mata Zetas and Los Torcidos)^{[214][215][216][217]} is a Mexican criminal group based in Jalisco and headed by Nemesio Oseguera Cervantes ("El Mencho"), one of Mexico's most-wanted drug lords.^[218] Jalisco New Generation Cartel started as one of the splits of Milenio Cartel, beside La Resistencia. La Resistencia accused CJNG of giving up Oscar Valencia (El Lobo) to the authorities and called them Los Torcidos (The Twisted Ones). Jalisco Cartel defeated La Resistencia and took control of Millenio Cartel's smuggling networks. Jalisco New Generation Cartel expanded its operation network from coast to coast in only six months, making it one of the criminal groups with the greatest operating capacity in Mexico as of 2012.^[219] Through online videos, the Jalisco New Generation Cartel has tried to seek society's approval and tacit consent from the Mexican government to confront Los Zetas by posing as a "righteous" and "nationalistic" group.^[220][221] Such claims have stoked fears that Mexico, just like Colombia a generation before, may be witnessing the rise of paramilitary drug gangs.^[220] By 2018 the CJNG was hyped as the most powerful cartel in Mexico.^{[222][223][224]} though Insight Crime has said the Sinaloa Cartel is still the most powerful cartel and called the CJNG its closest rival.^[225][173] In 2019, the group was greatly weakened by infighting, arrests of senior operatives, and a war with the Sinaloa Cartel and its allies,^[226]

CJNG co-founder Érick Valencia Salazar (alias "El 85") and former high-ranking CJNG leader Enrique Sánchez Martínez (alias "El Cholo") had also departed from the CJNG and formed a rival cartel known as the Nueva Plaza Cartel.^{[227][228][229]} Since 2017, the cartel has been engaged in a war with the CJNG.^[230] The Nueva Plaza Cartel has also become aligned with the Sinaloa Cartel to fight the CJNG.^[227][228]

Criminal organizations in Mexico are heavily involved in information warfare. These groups have a variety of tools they use to influence public opinion, such as food handouts, sponsoring of community development, social media posts, filmed press release-style video communications, physical narco messages, narco corridos, and private messaging such as WhatsApp chats. The goal of narco propaganda is to influence public opinion, threaten or accuse rivals, and generally communicate with those outside their organization.^[231] Many cartels have controlled the information environment by threatening journalists, bloggers, and others who speak out against them.

Their primary method of communication is the physical narco message, which can range from professionally-printed banners to hastily written messages on cardboard or paper. They are commonly displayed in public places, such as bridges, town centers, and highways. Many are often also left at crime scenes, such as after an assassination.

Some cartels, such as the CJNG, have sophisticated propaganda arms capable of producing large numbers of professional styled narco messages to advance their interests. These messages use stock phrases or slogans, cartel logos, and have cohesive messaging.^[232]

In 2011, then President Felipe Calderón (2006–2012) met with Mexico's major media outlets to discuss their role in what he argued was sensationalizing the violence and providing free press coverage to cartels and their messages. They agreed to limit coverage of the drug war and the messaging of criminal groups.^[233]

Paramilitary groups work alongside cartels to provide protection. This protection began with a focus on maintaining the drug trade, then moved to theft from other valuable industries such as oil and mining. It has been suggested that the rise in paramilitary groups coincides with a loss of security within the government. These paramilitary groups came about in a number of ways. First, waves of elite armed forces and government security experts have left the government to join the side of the cartels, responding to large bribes and an opportunity for wealth they may not have received in government positions. One such paramilitary group, Los Zetas, employed military personnel to create one of the largest groups in Mexico. Some of the elite armed forces members who join paramilitaries are trained in the Western Hemisphere Institute for Security Cooperation (WHINSEC, formerly known as the School of the Americas). One theory is that the paramilitaries have sprung out of deregulation of the Mexican army, which has been slowly replaced by private security firms.^[234] Paramilitaries, including the Zetas, have now entered uncharted territories. Branching out of just protecting drug cartels, paramilitary groups have entered many other financially profitable industries, such as oil, gas, kidnapping, and counterfeiting electronics. There has been a complete and total loss of control by the government, and the only response has been to increase army presence, notably an army whose officials are often on the drug cartels payroll. The United States has stepped in to offer support in the "War on Drugs" through funding, training and military support, and transforming the Mexican judicial system to parallel the American system.^[235]

Women in the Mexican drug war have been participants and civilians. They have served for and/or been harmed by all belligerents. There have been female combatants in the military, police, cartels, and gangs.^[236][237] Women officials, judges, prosecutors, lawyers, paralegals,^[238] reporters, business owners, social media influencers, teachers, and non-governmental organizations directors and workers have also been involved in different capacities.^[239] Women citizens and foreigners, including migrants,^[240] have been raped,^[241][242] tortured,^[243][244] and murdered in the conflict.^{[245][246][247][248][249]}

Women's involvement in the cartel is noticeably less than males, but they do play an important role nonetheless. Often, because no one would suspect a woman to commit such a serious crime, it makes them the perfect smuggler. Women smugglers could drive up to a checkpoint with a car full of drugs, and more often than not, no one would suspect them of anything. ^[250]

Women may find allure in a criminal lifestyle for the sense of freedom. Mexico already has a male-dominated culture, but by working in the drug trade, they can be empowered and even liberated. If women cannot obtain freedom through legal means, then it is possible they will use illegal avenues to achieve the same goal.^[251] 

Cartels and gangs fighting in the conflict carry out sex trafficking in Mexico as an alternative source of profits.^{[252][253][254][255]} Some members of the criminal organizations also abduct women and girls to use as their personal sex slaves^[252] and carry out sexual assault of migrants from Latin America to the United States.^[256]

Mexicans have a constitutional right to own firearms,^[257] but legal purchase from the single Mexican gun shop in Mexico City is extremely difficult.^[258] Firearms that make their way to Mexico come primarily from the American civilian market.^[259][260] Most grenades and rocket-launchers are smuggled through Guatemalan borders, as leftovers from past conflicts in Nicaragua.^[261] Some grenades are also smuggled from the U.S. to Mexico^[262] or stolen from the Mexican military.^[263]

The most common weapons used by the cartels are the AR-15, M16, M4, AK-47, AKM and Type 56 assault rifles. Handguns are very diverse, but the FN Five-seven (dubbed Matapolicías or Cop-killer by criminals)^[264] is a popular choice due to its armor-piercing capability.^[265] Grenade launchers are known to have been used against Mexican security forces, while H&K G36s and M4 carbines with M203 grenade launchers have been confiscated.

Some researchers have asserted that most weapons and arms trafficked into Mexico come from gun dealers in the United States. There is strong evidence for this conclusion, and there is a geographic coincidence between the supposed American origin of the firearms and the places where these weapons are seized, mainly in the northern Mexican states.^[266] Most grenades and rocket-launchers are smuggled through Guatemalan borders from Central America.^[261] Some grenades are also smuggled from the US to Mexico^[262] or stolen from the Mexican military.^[263] United States Department of Homeland Security (DHS) officials have stated that the statistic is misleading: out of approximately 30,000 weapons seized in drug cases in Mexico in 2004–2008, 7,200 appeared to be of U.S. origin, approximately 4,000 were found in ATF manufacturer and importer records, and 87 percent of those—3,480—originated in the United States.^[267][268]

In an effort to control smuggling of firearms, the U.S. government is assisting Mexico with technology, equipment and training.^[269] Project Gunrunner was one such effort between the U.S. and Mexico to collaborate in tracing Mexican guns which were manufactured in or imported legally to the U.S.^[270]

In 2008, it was falsely reported that ninety percent of arms either captured in Mexico or interdicted were from the United States. The DHS and others have dismissed these claims, pointing that the Mexican sample submitted for ATF tracing is the fraction of weapons seized that appear to have been made in the U.S. or imported into the U.S.^[267][268]

In 2015, official reports of the U.S. government and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) revealed that over the last years, Mexican cartels improved their firearm power, and that 71% of their weapons come from the U.S. Many of those guns were manufactured in Romania and Bulgaria, and then imported into the U.S. The Mexican cartels acquire those firearms mainly in the southern states of Texas, Arizona and California. After the United States, the top five countries of origin of firearms seized from Mexico were Spain, China, Italy, Germany and Romania. These five countries represent 17% of firearms smuggled into Mexico.^[271] Some cartels such as the Beltrán Leyva Cartel use counterfeit M16s made with aftermarket parts.^[272]

ATF Project Gunrunner has stated that the official objective is to stop the sale and export of guns from the United States into Mexico in order to deny Mexican drug cartels the firearms considered "tools of the trade".^[273] In February 2011, it brought about a scandal when the project was accused of accomplishing the opposite by ATF permitting and facilitating "straw purchase" firearm sales to traffickers, and allowing the guns to "walk" and be transported to Mexico. Allegedly, the ATF allowed to complete the transactions to expose the supply chain and gather intelligence.^[274][275] It has been established that this operation violated long-established ATF policies and practices and that it is not a recognized investigative technique.^[276] Several of the guns sold under the Project Gunrunner were recovered from crime scenes in Arizona,^[277] and at crime scenes throughout Mexico,^[278] resulting in considerable controversy.^{[279][280][281]}

One notable incident was the "Black Swan operation" where Joaquín Guzmán Loera was finally captured. The ATF confirmed that one of the weapons the Mexican Navy seized from Guzmán's gunmen was one of the many weapons that were "lost" during the Project Gunrunner.^[282]

Many weapons from Project Gunrunner were found in a secret compartment in the "safe house" of José Antonio Marrufo "El Jaguar", one of Guzmán's most sanguinary lieutenants. He is accused of many killings in Ciudad Juárez, including the notorious massacre of 18 patients at a "El Aliviane" rehabilitation center. It is believed that Marrufo armed his gunmen with weapons purchased in the United States.^[283]

Although violence between drug cartels had been occurring long before the war began, the government held a generally passive stance regarding cartel violence in the 1990s and early 2000s. That changed on December 11, 2006, when newly elected President Felipe Calderón sent 6,500 Federal troops to the state of Michoacán to end drug violence there. This action is regarded as the first major operation against organized crime, and became the starting point of the war between the government and the drug cartels.^[284] Calderón escalated his anti-drug campaign, in which there are now about 45,000 troops involved in addition to state and federal police forces. In 2010, Calderón said that the cartels seek "to replace the government" and "are trying to impose a monopoly by force of arms, and are even trying to impose their own laws".^[285]

As of 2011, Mexico's military captured 11,544 people who were believed to have been involved with the cartels and organized crime.^[286] In the year prior, 28,000 individuals were arrested on drug-related charges. The decrease in eradication and drug seizures, as shown in statistics calculated by federal authorities, poorly reflects Calderón's security agenda. Since the war began, over forty thousand people have been killed as a result of cartel violence. During Calderón's presidential term, the murder rate of Mexico increased dramatically.^[287]

Although Calderón set out to end the violent warfare between rival cartel leaders, critics argue that he inadvertently made the problem worse. The methods that Calderón adopted involved confronting the cartels directly. These aggressive methods have resulted in public killings and torture from both the cartels and the country's own government forces, which aids in perpetuating the fear and apprehension that the citizens of Mexico have regarding the war on drugs and its negative stigma. As cartel leaders are removed from their positions, by arrest or death, power struggles for leadership in the cartels have become more intense, resulting in enhanced violence within the cartels themselves.^[288]

Calderón's forces concentrate on taking down cartel members that have a high ranking in the cartel in an attempt to take down the whole organization. The resulting struggle to fill the recently vacated position is one that threatens the existence of many lives in the cartel. Typically, many junior-level cartel members then fight amongst one another, creating more and more chaos. The drug cartels are more aggressive and forceful now than they were in the past and at this point, the cartels hold much of the power in Mexico. Calderón relies heavily on the military to defend and fight against cartel activity. Calderón's military forces have yet to yield significant results in dealing with the violent cartels due in part to the fact that many police working for the Mexican government are suspected of corruption. There is suspicion that cartels have corrupted and infiltrated the military at a high level, influencing many generals and officers. Mexico's National Human Rights Commission has received nearly 5,800 complaints regarding military abuse since the beginning of the drug war in 2006. Additionally, the National Human Rights Commission has completed nearly 90 in-depth reports since 2007, addressing the many human rights violations of civilians that have occurred while the military officers were actively participating in law enforcement activities.^[289]

Violence in May 2012 in which nearly 50 bodies were found on a local highway between the Mexico–United States border and Monterrey has led to the arrests of 4 high-ranking Mexican military officials.^[290] These officials were suspected of being on the cartel payrolls and alerting them before military action against them. Such actions demonstrate that Calderón's significant military offensive will continue to reveal mixed results until the military itself is rid of the corrupting influences of the cartels whom they supposedly aim to persecute.^{[neutrality is disputed]}

In April 2008, General Sergio Aponte, the man in charge of the anti-drug campaign in the state of Baja California, made a number of allegations of corruption against the police forces in the region. Among his allegations, Aponte stated that he believed Baja California's anti-kidnapping squad was actually a kidnapping team working in conjunction with organized crime, and that bribed police units were used as bodyguards for drug traffickers.^[291]

These accusations sent shock waves through state government. Many of the more than 50 accused officials quit or fled. The progress against drug cartels in Mexico has been hindered by bribery, intimidation, and corruption; four months later the General was relieved of his command.^[292]

On April 26, 2008, a major battle took place between members of the Tijuana and Sinaloa cartels in the city of Tijuana, Baja California, that left 17 people dead.^[293]

In March 2009, President Calderón called in an additional 5,000 Mexican Army troops to Ciudad Juárez. The DHS also said that it was considering using state National Guard troops to help the U.S. Border Patrol counter the threat of drug violence in Mexico from spilling over the border into the U.S. The governors of Arizona and Texas have encouraged the federal government to use additional National Guard troops from their states to help those already there supporting state law enforcement efforts against drug trafficking.^[294]

According to the National Drug Intelligence Center, Mexican cartels are the predominant smugglers and wholesale distributors of South American cocaine and Mexico-produced cannabis, methamphetamine and heroin. Mexico's cartels have existed for some time, but have become increasingly powerful in recent years with the demise of the Medellín and Cali cartels in Colombia. The Mexican cartels are expanding their control over the distribution of these drugs in areas controlled by Colombian and Dominican criminal groups, and it is now believed they control most of the illegal drugs coming into the U.S.^[295]

No longer mere intermediaries for Colombian producers, Mexican cartels are now powerful organized-crime syndicates that dominate the drug trade in the Americas.

Mexican cartels control large swaths of Mexican territory and dozens of municipalities, and they exercise increasing influence in Mexican electoral politics.^[296] Cartels have waged violent turf battles over control of key smuggling corridors from Matamoros to San Diego. Mexican cartels employ hitmen and groups of enforcers, known as sicarios. The U.S. Drug Enforcement Administration reports that the Mexican drug cartels operating today along the border are far more sophisticated and dangerous than any other organized criminal group in U.S. law enforcement history.^[295] The cartels use grenade launchers, automatic weapons, body armor, Kevlar helmets, and sometimes unmanned aerial vehicles.^{[297][298][299][300]} Some groups have also been known to use improvised explosive devices (IEDs).^[301]

Casualty numbers have escalated significantly over time. According to a Stratfor report, the number of drug-related deaths in 2006 and 2007 (2,119 and 2,275) more than doubled to 5,207 in 2008. The number further increased substantially over the next two years, from 6,598 in 2009 to over 11,000 in 2010. According to data of the Mexican government, the death numbers are even higher: 9,616 in 2009, 15,273 in 2010, coming to a total of 47,515 killings since their military operations against drug cartels began in 2006, as stated in the government's report of January 2012.^{[301][302][303]}

On October 7, 2012, the Mexican Navy responded to a civilian complaint reporting the presence of armed gunmen in Sabinas, Coahuila. Upon the navy's arrival, the gunmen threw grenades at the patrol from a moving vehicle, triggering a shootout that left Lazcano and another gunman dead and one marine slightly wounded.^[304] The vehicle was found to contain a grenade launcher, 12 grenades, possibly a rocket-propelled grenade launcher and two rifles, according to the navy.^[305] The Navy confirmed his death through fingerprint verification and photographs of his corpse before handing the body to the local authorities.^[306] Lazcano is the most powerful cartel leader to be killed since the start of Mexico's drug war in 2006, according to Reuters.^[307]

This death came just hours after the navy arrested a high-ranking Zeta member in Nuevo Laredo, Tamaulipas, Salvador Alfonso Martínez Escobedo.

The death of Lazcano benefited three parties; the Mexican Navy, who scored a significant blow to organized crime with the death of Lazcano, Miguel Treviño Morales, who rose as the "uncontested" leader of Los Zetas, and Joaquín "El Chapo" Guzmán, the leader of the Sinaloa Cartel and the main rival of Los Zetas. El Chapo was perhaps the biggest winner of the three, since his primary goal was to take over the smuggling routes in Nuevo Laredo, Tamaulipas, the headquarters of Treviño Morales.^[308] If the body had not been stolen, it would also have been a symbolic victory for Felipe Calderón, who could have said that his administration took down one of the founders and top leaders of Los Zetas and consequently boost the morale of the Mexican military.^[309]

Organized crime homicides in Mexico^[310]

Year	Killed
2007	2,774
2008	5,679
2009	8,281
2010	12,658
2011	12,284
2012	12,412
2013	10,094
2014	7,993
2015	8,423
2016	10,967
2017	12,500
2018	22,500

It is often not clear what deaths are part of the Mexican drug war versus general criminal homicides, and different sources give different estimates.^[311] Casualties are often measured indirectly by estimated total deaths from organized crime in Mexico.^[311] This amounts to about 115,000 people in the years 2007–2018.^[310] From 2018 to 2020, it was estimated that there were 11,400 reports of gang violence, and over 80% of the attacks targeted civilians, resulting in 13,000 related-deaths during the period.^[312]

The Mexican attorney general's office has claimed that 9 of 10 victims of the Mexican drug war are members of organized-crime groups,^[313] although this figure has been questioned by other sources.^[314] Deaths among military and police personnel are an estimated 7% of the total.^[315] The states that suffer from the conflict most are Baja California, Guerrero, Chihuahua, Michoacán, Tamaulipas, Nuevo León and Sinaloa.

By January 2007, these various operations had extended to the states of Guerrero as well as the so-called "Golden Triangle States" of Chihuahua, Durango, and Sinaloa. In the following February the states of Nuevo León and Tamaulipas were included as well.

Seizures and arrests have jumped since Calderón took office in December 2006, and Mexico has extradited more than 100 people wanted in the U.S.^{[citation needed]}

On July 10, 2008, the Mexican government announced plans to nearly double the size of its Federal Police force to reduce the role of the military in combating drug trafficking.^[316] The plan, known as the Comprehensive Strategy Against Drug Trafficking, also involves purging local police forces of corrupt officers. Elements of the plan have already been set in motion, including a massive police recruiting and training effort intended to reduce the country's dependence in the drug war on the military.^{[citation needed]}

On July 16, 2008, the Mexican Navy intercepted a 10-meter long narco-submarine travelling about 200 kilometers off the southwest of Oaxaca; in a raid, Special Forces rappelled from a helicopter onto the deck of the submarine and arrested four smugglers before they could scuttle their vessel. The vessel was found to be loaded with 5.8 tons of cocaine and was towed to Huatulco, Oaxaca, by a Mexican Navy patrol boat.^{[317][318][319][320][321]}

One escalation in this conflict is the traffickers' use of new means to claim their territory and spread fear. Cartel members have broadcast executions on YouTube^[322] and on other video sharing platforms or shock sites. Cartels have also hung banners on streets stating demands and warnings.^[323]

The 2008 Morelia grenade attacks took place on September 15, 2008, when two hand grenades were thrown onto a crowded plaza, killing ten people and injuring more than 100.^[324] Some see these efforts as intended to sap the morale of government agents assigned to crack down on the cartels; others see them as an effort to let citizens know who is winning the war. At least one dozen Mexican norteño musicians have been murdered. Most of the victims performed what are known as narcocorridos, popular folk songs that tell the stories of the Mexican drug trade—and celebrate its leaders as folk heroes.^[325]

Increasing violence has jeopardized foreign investment in Mexico. Finance Minister, Agustín Carstens, said that the deteriorating security alone is reducing gross domestic product annually by 1% in Mexico, Latin America's second-largest economy.^[326]

Teachers in the Acapulco region were "extorted, kidnapped and intimidated" by cartels, including death threats demanding money. They went on strike in 2011.^[327]

Mexican cartels advance their operations, in part, by corrupting or intimidating law enforcement officials.^[291][124] Mexican municipal, state, and federal government officials, along with the police forces, often work together with the cartels in an organized network of corruption.^[38] A Pax Mafioso, is a specific example of corruption which guarantees a politician votes and a following in exchange for not impeding a particular cartel.^[38]

The International Narcotics Control Board (INCB) reports that although the central government of Mexico has made concerted efforts to reduce corruption in recent years, it remains a serious problem.^[328][329] Some agents of the Federal Investigations Agency (AFI) are believed to work as enforcers for various cartels, and the Attorney General (PGR) reported in December 2005 that nearly 1,500 of AFI's 7,000 agents were under investigation for suspected criminal activity and 457 were facing charges.^[124]

In recent years, the federal government conducted purges and prosecution of police forces in Nuevo Laredo, Michoacán, Baja California and Mexico City.^[124] The anti-cartel operations begun by President Calderón in December 2006 includes ballistic checks of police weapons in places where there is concern that police are also working for the cartels. In June 2007, President Calderón purged 284 federal police commanders from all 31 states and the Federal District.^[124]

Under the 'Cleanup Operation' performed in 2008, several agents and high-ranking officials have been arrested and charged with selling information or protection to drug cartels;^[330][331] some high-profile arrests were: Victor Gerardo Garay Cadena,^[332] (chief of the Federal Police), Noé Ramírez Mandujano (ex-chief of the Organized Crime Division (SEIDO)), José Luis Santiago Vasconcelos (ex-chief of the Organized Crime Division (SEIDO)), and Ricardo Gutiérrez Vargas who is the ex-director of Mexico's Interpol office. In January 2009, Rodolfo de la Guardia García, ex-director of Mexico's Interpol office, was arrested.^[333] Julio César Godoy Toscano, who was just elected July 6, 2009, to the lower house of Congress, is charged with being a top-ranking member of La Familia Michoacana drug cartel and of protecting this cartel.^[334] He is now a fugitive.

In May 2010, an NPR report collected allegations from dozens of sources, including U.S. and Mexican media, Mexican police officials, politicians, academics, and others, that Sinaloa Cartel had infiltrated and corrupted the Mexican federal government and the Mexican military by bribery and other means. According to a report by the U.S. Army Intelligence section in Leavenworth, over a six-year period, of the 250,000 soldiers in the Mexican Army, 150,000 deserted and went into the drug industry.^[335]

The 2010 NPR report also stated that the Sinaloa Cartel was colluding with the government to destroy other cartels and protect itself and its leader, 'Chapo'. Mexican officials denied any corruption in the government's treatment of drug cartels.^[168][169] Cartels had previously been reported as difficult to prosecute "because members of the cartels have infiltrated and corrupted the law enforcement organizations that are supposed to prosecute them, such as the Office of the Attorney General."^[336]

The drug control policies Mexico has adopted to prevent drug trafficking and to eliminate the power of the drug cartels have adversely affected the human rights situation in the country. These policies have given the responsibilities for civilian drug control to the military, which has the power to not only carry out anti-drug and public security operations but also enact policy. According to the U.S. State Department, the police and the military in Mexico were accused of committing serious human rights violations as they carried out government efforts to combat drug cartels.^[337]

Some groups are especially vulnerable to human rights abuses collateral to drug law enforcement. Specifically in northern border states that have seen elevated levels of drug-related violence, human rights violations of injection drug users (IDUs) and sex workers by law enforcement personnel include physical and sexual violence, extortion, and targeting for accessing or possession of injection equipment or practicing sex work, although these activities are legal.^{[338][339][340]} Such targeting is especially deleterious because members of these marginalized communities often lack the resources and social or political capital to enforce their rights.^{[338][339][340]}

Immense power in the executive branch and corruption in the legislative and judiciary branches also contribute to the worsening of Mexico's human rights situation, leading to such problems as police forces violating basic human rights through torture and threats, the autonomy of the military and its consequences and the ineffectiveness of the judiciary in upholding and preserving basic human rights. Some of the forms of human rights violations in recent years presented by human rights organizations include illegal arrests, secret and prolonged detention, torture, rape, extrajudicial execution, and fabrication of evidence.^{[341][342][343]}

Drug policy fails to target high-level traffickers. In the 1970s, as part of the international Operation Condor, the Mexican government deployed 10,000 soldiers and police to a poverty-stricken region in northern Mexico plagued by drug production and leftist insurgency. Hundreds of peasants were arrested, tortured, and jailed, but no major drug traffickers were captured.^[344]

The emergence of internal federal agencies that are often unregulated and unaccountable also contributes to the occurrence of human rights violations.^{[according to whom?]} The AFI of Mexico had been involved with numerous human rights violation cases involving torture and corruption. In one case, detainee Guillermo Velez Mendoza died while in the custody of AFI agents. The AFI agent implicated in his death was arrested and escaped on bail.^[345]

Similarly, nearly all AFI agents evaded punishment and arrest due to the corrupt executive and judiciary system and the supremacy of these agencies.^{[citation needed]} The Attorney General's Office reported in December 2005 that one-fifth of its officers were under investigation for criminal activity, and that nearly 1,500 of AFI's 7,000 agents were under investigation for suspected criminal activity and 457 were facing charges.^[124][346] The AFI was finally declared a failure and was disbanded in 2009.^[347]

Ethnic prejudices have also emerged in the drug war, and poor and helpless indigenous communities have been targeted by the police, military, drug traffickers and the justice system. According to the National Human Rights Commission (Mexico) (Comisión Nacional de los Derechos Humanos-CNDH), nearly one-third of the indigenous prisoners in Mexico in 2001 were in prison for federal crimes, which are mostly drug-related.^[348]

Another major concern is the lack of implementation of the Leahy Law in U.S. and the consequences of that in worsening the human rights situation in Mexico. Under this U.S. law, no member or unit of a foreign security force that is credibly alleged to have committed a human rights violation may receive U.S. security training. It is alleged^{[by whom?]} that the U.S., by training the military and police force in Mexico, is in violation of the Leahy Law. In this case, the U.S. embassy officials in Mexico in charge of human rights and drug control programs are blamed with aiding and abetting these violations. In December 1997, a group of heavily armed Mexican special forces soldiers kidnapped twenty young men in Ocotlan, Jalisco, brutally torturing them and killing one. Six of the implicated officers had received U.S. training as part of the Grupo Aeromóvil de Fuerzas Especiales (GAFE) training program.^[349]

As a result of "spillover" along the U.S.-bound drug trafficking routes and more stringent border enforcement, Mexico's northern border states have seen increased levels of drug consumption and abuse, including elevated rates of drug injection 10 to 15 times the national average.^{[338][351][352]} These rates are accompanied by mounting rates of HIV and STIs among injection drug users (IDUs) and sex workers, reaching a 5.5% prevalence in cities such as Tijuana and Ciudad Juárez, which also report STI rates of 64% and 83%, respectively.^[338] Violence and extortion of IDUs and sex workers directly and indirectly elevate the levels of risk behavior and poor health outcomes among members of these groups.^[338][353] Marginalization of these vulnerable groups by way of physical and sexual violence and extortion by police threatens the cross-over of infection from high-prevalence groups to the general population.^{[338][354][355]} In particular, decreased access to public health services such as syringe exchange programs and confiscation of syringes can precipitate a cascade of health harms.^{[356][357][358]} Geographic diffusion of epidemics from the northern border states elsewhere is also possible with the rotation of police and military personnel stationed in drug conflict areas with high infection prevalence.^{[338][354][355]}

The increase in violence related with organized crime has significantly deteriorated the conditions in which local journalism is practiced.^[359] In the first years of the 21st century, Mexico was considered the most dangerous country in the world to practice journalism, according to groups like the National Human Rights Commission, Reporters Without Borders, and the Committee to Protect Journalists. Between 2000 and 2012, several dozen journalists, including Miguel Ángel López Velasco, Luis Carlos Santiago, and Valentín Valdés Espinosa, were murdered there for covering narco-related news.^[360][361]

The offices of Televisa and local newspapers have been bombed.^[362] The cartels have also threatened to kill news reporters in the U.S. who have done coverage on the drug violence.^[363] Some media networks simply stopped reporting on drug crimes, while others have been infiltrated and corrupted by drug cartels.^[364][365] In 2011, Notiver journalist Miguel Angel Lopez Velasco, his wife, and his son were murdered in their home.^[366]

About 74 percent of the journalists killed since 1992 in Mexico have been reporters for print newspapers, followed in number by Internet media and radio at about 11 percent each. Television journalism only includes 4 percent of the deaths.^[367] These numbers are not proportional to the audience size of the different mediums; most Mexican households have a television, a large majority have a radio, but only a small number have the internet, and the circulation numbers for Mexican newspapers are relatively low.^[368][369]

Since harassment neutralized many traditional media outlets, anonymous, sensationalized blogs like Blog del Narco took on the role of reporting on events related to the drug war.^[370] The drug cartels responded by murdering bloggers and social media users. Twitter users have been tortured and killed for posting and denouncing information of the drug cartels' activities.^[371] In September 2011, user NenaDLaredo of the website Nuevo Laredo Envivo was allegedly murdered by Los Zetas.^[372]

In May 2012, several journalist murders occurred in Veracruz. Regina Martinez of Proceso was murdered in Xalapa. A few days later, three Veracruz photojournalists were tortured and killed and their dismembered bodies were dumped in a canal. They had worked for various news outlets, including Notiver, Diario AZ, and TV Azteca. Human rights groups condemned the murders and demanded the authorities investigate the crimes.^{[361][373][374]}

Since the start of the Mexican drug war in 2006, the drug trafficking organizations have slaughtered their rivals, killed policemen, and have increasingly targeted politicians – especially local leaders.^[375] Most of the places where these politicians have been killed are areas plagued by drug-related violence.^[375] Part of the strategy used by criminal groups behind the killings of local figures is the weakening of the local governments.^[375] For example, María Santos Gorrostieta Salazar, former mayor of Tiquicheo, Michoacán, who had survived three earlier assassination attempts and the murder of her husband, was abducted and beaten to death in November 2012.^[376] Extreme violence puts politicians at the mercy of the cartels, allowing them to increase their control of government structures and expand their influence.^[375]

In addition, because mayors usually appoint local police chiefs, they are seen by the cartels as key assets in their criminal activities to control the police forces in their areas of influence.^[377] The cartels also seek to control the local governments to win government contracts and concessions; these "public works" help them ingrain themselves in the community and gain the loyalty and respect of the communities in which they operate.^[377] Politicians are usually targeted for three reasons: (1) Political figures who are honest pose a direct threat to organized crime, and are consequently killed by the cartels; (2) Politicians make arrangements to protect a certain cartel and are killed by a rival cartel; and (3) A cartel kills politicians to heat up the turf of the rival cartel that operates in the area.^[378]

Cartels have engaged in kidnapping, ransom, murder, robbery, and extortion of migrants traveling from Central America through Mexico on their way to the United States and Canada. Cartels have also forced migrants to join their organization and work for them, a situation that has been described as slavery.^[379][380] Mass graves have been also discovered in Mexico containing bodies of migrants.^[381] In 2011, 177 bodies were discovered in a mass grave in San Fernando, Tamaulipas, the same area where the bodies of 72 migrants were discovered in 2010,^[382] where most victims "died of blunt force trauma to the head."^[383]

Cartels have also infiltrated the Mexican government's immigration agencies, and attacked and threatened immigration officers.^[384] The National Human Rights Commission of Mexico (Comisión Nacional de los Derechos Humanos, CNDH) said that 11,000 migrants had been kidnapped in 6 months in 2010 by drug cartels.^[385]

There are documented links between the drug cartels and human trafficking for forced labor, forced prostitution, and rape. The wife of a drug lord described a system in which young girls became prostitutes and then were forced to work in drug factories.^[386] In the early 2010s, Los Zetas reportedly began to move into the prostitution business (including the prostitution of children) after previously only supplying women to already existing networks.^[387]

The U.S. State Department says that the practice of forced labor in Mexico is larger in extent than forced prostitution.^[388] Mexican journalists like Lydia Cacho have been threatened and forced into exile for reporting on these events.^[389]

Improved cooperation between Mexico and the U.S. has led to the arrests of hundreds of Sinaloa Cartel suspects in U.S. cities and towns, but the U.S. market is being eclipsed by booming demand for cocaine in Europe, where users now pay twice the going U.S. rate.^[39] In 2008, U.S. Attorney General Michael Mukasey announced that an international drug interdiction operation, Project Reckoning, involving law enforcement in the United States, Italy, Canada, Mexico and Guatemala had netted more than 500 organized crime members involved in the cocaine trade. The announcement highlighted the Italian-Mexican cocaine connection.^[54]

Concerns about European security and the trafficking of drugs through the European continent have grown in recent years, and, in December 2022, Europol (the law enforcement agency of the EU) and the DEA released a joint report on the situation involving Mexican drug trafficking through the EU.^[390]

In December 2011, the government of Spain remarked that Mexican cartels had multiplied their operations in that country, becoming the main entry point of cocaine into Europe.^[391]

In 2012, it was reported that Mexican drug cartels had joined forces with the Sicilian Mafia, when Italian officials unearthed information that Palermo's black market, along with other Italian ports, was used by Mexico's drug cartels as a conduit to bring drugs to the European market, in which they had been trafficking drugs, particularly cocaine, throughout the Atlantic Ocean for over 10 years to Europe.^[392]

In 2016, investigation into transatlantic drug trafficking revealed that the Kinahan Clan, Ireland's largest drug trafficker, among other prominent drug traffickers in Mexico, South America, West Africa, and Europe had created an informal "Super Cartel" in an attempt to improve business and increase buyers. However, the extent of the prevalence of the Super Cartel is largely unknown, since many trafficking relationships may exist without any real central plan.^[393]

The 2017 guest list to the wedding of Daniel Kinahan led to the discovery of most of the key players in the Super Cartel Alliance. Those that have been most investigated include top underworld figures such as: Ridouan Taghi, Ricardo Riquelme Vega, aka El Rico, caged assassin Noufal Fassih and Italian Camorra boss Raffaele Imperiale.^[394]

In 2022/2023 - In January 2023, two alleged drug lords said to be kingpins in the mostly European Super Cartel were released just two months after being arrested in Dubai. Edin Gacanin, (Tito) a Dutch-Bosnian national described by the US Drug Enforcement Administration (DEA) as one of the top 50 drug traffickers in the world, and Zuhair Belkhair, a Dutch-Moroccan accused of trafficking huge amounts of cocaine through the port of Rotterdam, were among 49 suspects arrested in a massive, highly-publicised, international police operation. Most of the others arrested are awaiting trial or have pled guilty.

The Mexican Army crackdown has driven some cartels to seek a safer location for their operations across the border in Guatemala, attracted by corruption, weak policing and its position on the overland smuggling route.^[395][396] The smugglers pick up drugs from small planes that land at private airstrips hidden in the Guatemalan jungle. The cargo is then moved up through Mexico to the U.S. border. Guatemala has also arrested dozens of drug suspects and torched huge cannabis and poppy fields. The U.S. government sent speedboats and night-vision goggles under a regional drug aid package.^[397]

In February 2009, Los Zetas threatened to kill the president of Guatemala, Álvaro Colom.^[398] On March 1, 2010, Guatemala's chief of national police and the country's top anti-drugs official were arrested over alleged links to drug trafficking.^[396] A report from the Brookings Institution^[399] warns that, without proactive, timely efforts, the violence will spread throughout the Central American region.^[400]

According to the United States government, Los Zetas control 75% of Guatemala through violence, political corruption and infiltration in the country's institutions.^[401] Sources mentioned that Los Zetas gained ground in Guatemala after they killed several high-profile members and the supreme leader of Los Leones, an organized crime group from Guatemala.^[402]

At least nine Mexican and Colombian drug cartels have established bases in 11 West African nations.^[403] They have reportedly worked closely with local criminal gangs to carve out a staging area for access to the lucrative European market. The Colombian and Mexican cartels have discovered that it is easier to smuggle large loads into West Africa and then break that up into smaller shipments to Europe – mostly Spain, the United Kingdom and France.^[403] Higher demand for cocaine in Western Europe in addition to North American interdiction campaigns has led to dramatically increased trafficking in the region: nearly 50% of all non-U.S. bound cocaine, or about 13% of all global flows, is now smuggled through West Africa.^[404]

The Mexican Army severely curtailed the ability of the Mexican drug cartels to move cocaine inside the U.S. and Canada, prompting an upsurge in gang violence in Vancouver in 2009, where the cocaine price has increased from $23,300 to almost $39,000 per kilo as the Canadian drug markets experienced prolonged shortages.^[39] As evidence of this pressure, the U.S. government stated the amount of cocaine seized on U.S. soil dropped by 41 percent between early 2007 and mid-2008.^[39] Since 2009, Vancouver has become the Mexican drug cartels' main center of operations in Canada.^[405]

Patricio Pazmiño, the Interior Minister of Ecuador, stated that the February 2021 riots at three prisons that took 79 lives were related to Mexican and Colombian drug gangs. The government intercepted a record 126 tons of cocaine in 2020.^[406]

On September 8, 2021 National Prosecutor Jorge Abbott declared that Mexican cartels were attempting to establish themselves in Chile.^[407] It is known that Sinaloa Cartel has attempted to use Chile as a transit route for the shipment of cocaine to Rotterdam in the Netherlands.^[407] The activity of Jalisco New Generation Cartel includes an attempt at establishing a drug laboratory in Iquique as well as the import of marihuana through the port of San Antonio.^[407]

The U.S. Justice Department considers the Mexican drug cartels to be the "greatest organized crime threat to the United States."^[408] During the first 18 months of Calderón's presidency, the Mexican government spent about US$7 billion in the war against drugs.^{[citation needed]} In seeking partnership from the United States, Mexican officials point out that the illicit drug trade is a shared problem in need of a shared solution, and remark that most of the financing for the Mexican traffickers comes from American drug consumers.^[409] On March 25, 2009, U.S. Secretary of State Hillary Clinton stated that "[America's] insatiable demand for illegal drugs fuels the drug trade", and that "the United States bears shared responsibility for the drug-fueled violence sweeping Mexico."^[410]

U.S. State Department officials knew that Mexican ex-president Felipe Calderón's willingness to work with the United States was unprecedented on issues of security, crime and drugs, so the U.S. Congress passed legislation in late June 2008 to provide Mexico and Central American countries with US$1.6 billion for the Mérida Initiative, a three-year international assistance plan. The Mérida Initiative provides Mexico and Central American countries with law enforcement training and equipment, as well as technical advice to strengthen the national justice systems. The Mérida Initiative does not include cash or weapons.

Currently, the Mexican drug cartels already have a presence in most major U.S. cities.^[411] In 2009, the Justice Department reported that Mexican drug cartels distribute drugs in nearly 200 cities across the United States,^[412] including Los Angeles, Chicago and Atlanta.^[413] Gang-related activity and violence has increased along the U.S. Southwest border region, as U.S.-based gangs act as enforcers for Mexican drug cartels.^[414]

This section needs to be updated. Please help update this article to reflect recent events or newly available information. (November 2020)

U.S. authorities reported a spike in killings, kidnappings and home invasions connected to Mexican cartels, and at least 19 Americans were killed in 2008.^[415][416] Another 92 Americans were killed between June 2009 and June 2010.^[417]

The U.S. Joint Forces Command noted in a December 2008 report that in terms of worst-case scenarios, Mexico bears some consideration for sudden collapse in the next two decades as the government, its politicians, police, and judicial infrastructure are all under sustained assault and pressure by criminal gangs and drug cartels.^[418] The Joint Forces Command stated concern that the conflict will have a major impact on the stability of the Mexican state over the next several years, and therefore would demand an American response based on the implications for homeland security alone.^[418] After the JFC broached this issue in its 2008 report, several journalists and academics have discussed the possibility that Mexico could become a failed state.^{[419][420][421][422]}

The Mexican government responded negatively to the U.S. government raising the prospect of Mexico becoming a failed state.^[423] In a February 2009 interview with the Associated Press, President Calderón said it was "absolutely false" to label his country a failed state.^[424] To smooth over relations with Mexico over this issue, Secretary of State Hillary Clinton personally visited Mexico City in March 2009, followed by a visit by President Barack Obama a month later.^[423]

In March 2009, the U.S. DHS said that it was considering using the National Guard to counter the threat of drug violence in Mexico from spreading to the U.S. The governors of Arizona and Texas have asked the federal government to send additional National Guard troops to help those already there supporting local law enforcement efforts against drug trafficking.^[294] Calls for National Guard deployment on the border greatly increased after the 2010 murder of Arizona rancher Robert Krentz, possibly at the hands of Mexican drug smugglers.^[426][427]

In March 2009, the Obama administration outlined plans to redeploy more than 500 federal agents to border posts and redirect $200 million to combat smuggling of illegal drugs, money and weapons.^[428] On May 25, 2010, President Obama authorized deployment of 1,200 National Guard troops to the U.S. border with Mexico to assist with border protection and enforcement activities, as well as help train additional Customs and Border Protection agents.^[429] The Washington Office on Latin America said the U.S. southwest border region remained calm, with a homicide rate lower than the national average.^[430][431]

In 2021, around 80,411 people died from opioid overdoses in the United States.^[432] Many of the deaths are from an extremely potent opioid, fentanyl, which is trafficked from Mexico.^[433] The drug's precursor chemicals, which have a variety of legitimate uses, are manufactured in China, then shipped to Mexico, where it is processed and packaged, which is then smuggled into the US by drug cartels.^[434] In 2023, the Biden administration announced a crackdown on members of the Sinaloa Cartel smuggling fentanyl into the United States.^[435]

Vicente Zambada Niebla, a member of the Sinaloa Cartel and son of Ismael Zambada García, one of the top drug lords in Mexico, claimed after his arrest to his attorneys that he and other top Sinaloa cartel members had received immunity by U.S. agents and a virtual licence to smuggle cocaine over the United States border, in exchange for intelligence about rival cartels engaged in the Mexican drug war.^[436][437]

In October 2013, two former federal agents and an ex-CIA contractor told an American television network that CIA operatives including Félix Rodríguez were involved in the kidnapping and murder of DEA covert agent Enrique Camarena, because he was a threat to the agency's drug operations in Mexico. According to the three men, the CIA was collaborating with drug traffickers moving cocaine and marijuana to the United States, and using its share of the profits to finance Nicaraguan Contra rebels attempting to overthrow Nicaragua's Sandinista government. A CIA spokesman responded, calling it "ridiculous" to suggest that the Agency had anything to do with the murder of a U.S. federal agent or the escape of his alleged killer.^[438]

According to former Presidents Fernando Henrique Cardoso of Brazil, Ernesto Zedillo of Mexico and César Gaviria of Colombia, the United States-led drug war is pushing Latin America into a downward spiral; Mr. Cardoso said in a conference that "the available evidence indicates that the war on drugs is a failed war".^[439] The panel of the Latin American Commission on Drugs and Democracy commission, headed by Cardoso, stated that the countries involved in this war should remove the "taboos" and re-examine the anti-drug programs. Latin American governments have followed the advice of the U.S. to combat the drug war, but the policies had little effect. The commission made some recommendations to United States President Barack Obama to consider new policies, such as decriminalization of marijuana and to treat drug use as a public health problem and not as a security problem.^[440] The Council on Hemispheric Affairs states it is time to seriously consider drug decriminalization and legalization,^[441] a policy initiative that would be in direct opposition to the interests of criminal gangs.

Despite the fact that Mexican drug cartels and their Colombian suppliers generate, launder and remove $18 billion to $39 billion from the United States each year,^[442] the U.S. and Mexican governments have been criticized for their unwillingness or slow response to confront the various cartels' financial operations, including money laundering.^{[442][443][444]}

The U.S. DEA has identified the need to increase financial investigations relating to the movement of illegal drug funds to Mexico.^[445] The DEA states that attacking the financial infrastructure of drug cartels has to play a key role in any viable drug enforcement strategy.^[445][446] The U.S. DEA has noted that the U.S. and Mexican financial services industry continues to be a facilitator for drug money movement.^[445][447]

Following suit, in August 2010 President Felipe Calderón proposed sweeping new measures to crack down on the cash smuggling and money laundering. Calderón proposes a ban on cash purchases of real estate and of certain luxury goods that cost more than 100,000 pesos (about US$8,104.) His package would also require more businesses to report large transactions, such as real estate, jewelry and purchases of armor plating.^[444] In June 2010, Calderón "announced strict limits on the amount in U.S. dollars that can be deposited or exchanged in banks",^[444] but the proposed restrictions to financial institutions are facing tough opposition in the Mexican legislature.^[442][444]

In 2011, Wachovia, at one time a major U.S. bank, was implicated in laundering money for Mexican drug lords.^[448] In a settlement, Wachovia paid federal authorities $110 million in forfeiture.^[449] A U.S. Senate report^[450][451] from the permanent subcommittee for investigations revealed in July 2012 that HSBC – one of Europe's biggest banks- moved $7 billion in bulk cash from Mexico to the U.S., most of it suspected to assist Mexican drug lords and U.S. drug cartels in moving money to the U.S.^[452][453] While money laundering problems at HSBC have been flagged by regulators for nearly a decade, the bank continued to avoid compliance. On December 12, 2012, HSBC settled for a $1.93 billion fine.^[454]

RAND studies released in the mid-1990s found that using drug user treatment to reduce drug consumption in the United States is seven times more cost effective than law enforcement efforts alone, and it could potentially cut consumption by a third.^[455]

In FY2011, the Obama administration requested approximately $5.6 billion to support demand reduction. This includes a 13% increase for prevention and almost a 4% increase for treatment. The overall FY2011 counter-drug request for supply reduction and domestic law enforcement is $15.5 billion with $521.1 million in new funding.^[456]
