"After arriving from South Asia approximately a thousand years ago, cannabis quickly spread throughout the African continent. European accounts of cannabis in Africa—often fictionalized and reliant upon racial stereotypes—shaped widespread myths about the plant and were used to depict the continent as a cultural backwater and Africans as predisposed to drug use. These myths continue to influence contemporary thinking about cannabis. In The African Roots of Marijuana, Chris S. Duvall corrects common misconceptions while providing an authoritative history of cannabis as it flowed into, throughout, and out of Africa. Duvall shows how preexisting smoking cultures in Africa transformed the plant into a fast-acting and easily dosed drug and how it later became linked with global capitalism and the slave trade" (publisher).
