Brown-brown is a form of powdered cocaine, cut with gunpowder. Commonly given to child soldiers in West African armed conflicts,[1] the drug gained notoriety after it was used by Nicholas Cage's character, Yuri Orlov, in the 2005 movie Lord of War[2]. Consumed by insufflation, the gunpowder in the drug irritates the bowels which increases aggression.
It also appeared in the 2006 movie Blood Diamond, the memoir A Long Way Gone by Ishmael Beah and the video game Metal Gear Solid 2: Sons of Liberty.
