The Interdepartmental Committee on the Abuse of Dagga published convictions for possession, which in 1948 fell almost entirely on Africans and Coloured people, and concluded that smoking dagga does not in general act as an aphrodisiac but has a sedative effect. A pharmacologist who reviewed the subject in 1961 held that the plant is not native to southern Africa and is always cultivated, usually in secret.[1]
