Study: Cannabis Legalization Tied to Less Teen Use
New research suggests legalizing recreational marijuana for U.S. adults in some states may have slightly reduced teens’ odds of using pot.
To see how teen marijuana use compares in states with and without such laws, researchers examined survey data on substance use collected from 1.4 million adolescents between 1993 and 2017. During that period, 27 states and Washington, D.C. legalized medical marijuana and seven states legalized cannabis for recreational use.
Responses from 1.4 million high school students were included. The study was published in JAMA Pediatrics.
Medical marijuana laws didn’t seem to influence teen marijuana use, the study authors reported.
Recreational marijuana laws, however, were associated with an 8% decline in the odds that teens would report trying cannabis in the previous 30 days and a 9% decrease in teens reporting frequent use.
