No Increase In Problematic Cannabis Use Following Passage Of Medical Marijuana Laws

The enactment of medical marijuana laws is not associated with increased rates of problematic cannabis use, according to data published online in the journal Addiction.

Columbia University investigators assessed cannabis use trends in states in the years following the passage of medicalization. They reported “no significant change in the prevalence of past-month marijuana use among adolescents or young adults (those ages 18 to 25)” following legalization. They also found no evidence of increased cannabis abuse or dependence by either young people or adults. States with largely unregulated medical programs were associated with increased self-reported use by adults age 26 and older, but states with stricter programs were not.

The study’s findings are consistent with those of numerous other papers reporting no uptick in youth marijuana use or abuse following medical marijuana regulation, including those here, here, here, here, here, and here. The findings contradict those of a recent, widely publicized paper in JAMA Psychiatry which speculated that medical marijuana laws may increase the prevalence of cannabis use disorder among adults.

An abstract of the study, “Loose regulation of medical marijuana programs associated with higher rates of adult marijuana use but not cannabis use disorder,” is online here.

NORML's mission is to move public opinion sufficiently to legalize the responsible use of marijuana by adults, and to serve as an advocate for consumers to assure they have access to high quality marijuana that is safe, convenient and affordable
