Home Grown: Marijuana and the Origins of Mexico's War on Drugs

Examines how Mexican beliefs about marijuana causing madness led to Mexico’s 1920 prohibition (predating US prohibition) and how these ideas migrated north to fuel “reefer madness” sentiment. Campos is an associate professor at the University of Cincinnati. The book challenges the standard narrative that US drug policy was simply imposed on Mexico, showing Mexico’s own agency in constructing prohibitionist frameworks.
