About The Study: Using the most recently available 2011 to 2021 data, researchers found limited associations between recreational cannabis legalization and recreational cannabis retail sales with adolescent substance use, extending previous findings. Recreational cannabis legalization was associated with modest decreases in cannabis, alcohol, and e-cigarette use. Recreational cannabis retail sales were associated with lower e-cigarette use, and with lower likelihood but also increased frequency of cannabis use among users, leading to no overall change in cannabis use. 

Authors: Rebekah Levine Coley, Ph.D., of Boston College in Chestnut Hill, Massachusetts, is the corresponding author.
