Columbia University Report – Decriminalization Leads to Higher Consumption

Researchers at Columbia University have found that marijuana use is almost twice as high in states with medical marijuana laws compared to states without them. This, according to an article published in an upcoming issue of the journal Drug and Alcohol Dependence.

Another recent finding underscores that disturbing message. Among youths aged 12 to 17, marijuana usage rates are higher in states with medicinal marijuana laws, says a study in last month’s Annals of Epidemiology.

This is concerning, because marijuana, according to the National Institutes of Health, is linked with dependence, respiratory and mental illness, poor motor performance, and cognitive impairment, among other negative effects. In fact, more kids now go to treatment because of a primary marijuana condition than for any other drug, including alcohol.
