NORML Responds To Media Claim: “Pot As Addictive As Tobacco” -- Widely Reported Study Based Its Findings On Only 12 Subjects, Is Contradicted By The I

Baltimore, MD: The results of a recent study from Johns Hopkins University suggesting that quitting cannabis can trigger withdrawal symptoms as severe as those associated with quitting cigarettes are based on subjective reports from only twelve individuals, and are in sharp contrast to findings reported previously by the National Academy of Sciences, Institute of Medicine (IOM).

The widely reported study, published last week in the journal Drug and Alcohol Dependence, evaluated the behavior patterns of twelve participants selected at random to cease their use of marijuana and tobacco for five days. Participants reported their symptoms using a checklist that indicated scores for anger, aggression, anxiety, appetite change, irritability, restlessness, sleep difficulty, and other common withdrawal symptoms. Investigators found that subjects reported experiencing withdrawal symptoms of a similar nature and magnitude regardless of whether they were abstaining from tobacco or cannabis. "These results … suggest [that] cannabis withdrawal is clinically important," researchers concluded.
