The 1936 film Reefer Madness depicted cannabis as a drug that provoked uncontrollable insanity, leading to manslaughter, suicide and attempted rape. This was a ridiculous characterization of the effects of cannabis, but there is a long history of associating the drug with psychotic disorders. It is important to ensure we do not confuse correlation with causation and incite another Reefer Madness-style panic. By offering careful, evidence-based interpretations of the data, scientists can effectively contribute to policy decisions related to cannabis use and mental health.
