This is a set category.

Topics about chemical classes of psychoactive drugs in general should be placed in relevant topic categories.

By "chemical class of psychoactive drugs" is meant a set of chemical compounds defined by a chemical property. This category is for articles and categories about chemical classes of psychoactive drugs.

This category is non-diffusing. All articles and categories that fit the scope are to be included directly as members of this category, even if they are members of another member of this category. For example: Both Category:Cathinones and Category:Substituted amphetamines are members of this category notwithstanding that Category:Cathinones is a member of Category:Substituted amphetamines. However, articles about a specific drug like 6-APB are outside the scope of this category and therefore are not to be included directly here.
