Today, Smart Approaches to Marijuana (SAM), the leading, nonpartisan U.S. organization offering a science-based approach to marijuana policy, released the most comprehensive study to date today entitled: Lessons from Marijuana Legalization in Four U.S. States and D.C.“ This study, validated by scientists from around the country, found that since legalization, marijuana use has soared, the black market is thriving, and communities of color are being negatively affected.
The study found that legalized states are leading the nation in past-year marijuana use among every age group. Among those states, Colorado currently holds the lead for first-time marijuana use among youth aged 12-17, representing a 65% increase since legalization. Young adult use is also highest in legalized states. Further, the number of young people arrested for marijuana use in Colorado saw an increase from 2015-2016.
