Study: Legalized Medical Marijuana Doesn’t Impact Teen Use Rates

Investigators from the University of Colorado at Denver, the University of Oregon, and Montana State University assessed federal data on youth marijuana use and treatment episodes for the years 1993 to 2011 – a time period when 16 states authorized medical cannabis use. Authors reported, “Our results are not consistent with the hypothesis that the legalization of medical marijuana caused an increase in the use of marijuana among high school students. In fact, estimates from our preferred specification are small, consistently negative, and are never statistically distinguishable from zero.”
