US National Institute of Mental Health 1969 pamphlet on ‘Marihuana’
IN 1969, the US National Institute of Mental Health produced advice on ‘Marihuana’. The advice was that marijuana was “not a narcotic”:. It does “not cause physical dependence”. There are no withdrawal symptoms. Indeed, “No direct cause-and-effect link between the use of marihuana and narcotics has been found”. Although “users of one illicit drug may be exposed to a variety of them through contact with drugs sellers…”
Have attitudes changed over time?
