National Survey Shows Teen Use Dropping, Possible Substitution for Alcohol in Adults

The annual National Survey on Drug Use and Health released Thursday by the Substance Abuse and Mental Health Services Administration (SAMHSA) reports that teen marijuana use rates decreased nationally in 2016. Past-month use rates among adults increased slightly, but alcohol use rates among all age groups decreased, indicating the possibility that adults are substituting marijuana for alcohol.

Past-month use rates for the 12-17 age group decreased by 0.5% from 2015 to 6.5% nationally in 2016. This is the lowest level of marijuana use in this age group since 2002. The data also shows a steady decrease since 2014, when the first states to make marijuana legal for adults began allowing regulated retail sales. The full report is available here.

“Critics of legalization worry about the message being sent to youth by marijuana policy reform efforts, but the real message is that marijuana should only be used by responsible adults, and it seems to be sinking in. Regulating marijuana for adults reinforces that message and creates effective mechanisms for making it more difficult for teens to obtain marijuana,” said Morgan Fox, senior communications manager for the Marijuana Policy Project. “Marijuana is objectively less harmful than alcohol, and regulation gives adults the legal option to choose the safer substance.”

Federal Survey Finds Teen Marijuana Use Remains Unchanged Following Legalization

The federal government quietly published new national survey data in December that shows rates of teen marijuana use in Colorado and Washington — the first two states to legalize and regulate marijuana for adult use — decreased more than the national average in 2014-2015. Fewer teens in the two states are reportedly using marijuana than in 2012-2013, just prior to the commencement of legal adult marijuana sales.

The Substance Abuse and Mental Health Services Administration (SAMHSA) released the results of the 2014-2015 National Survey on Drug Use and Health (NSDUH) on Tuesday along with a press release that did not include any mention of marijuana.

According to the NSDUH:

-    In Colorado, the rate of 12-17-year-olds who used marijuana in the past month dropped 1.43 percentage points from 12.56% in 2013-2014 to 11.13% in 2014-2015, compared to 11.16% in 2012-2013. The rate of past-year use dropped 2.46 percentage points from 20.81% in 2013-2014 to 18.35% in 2014-2015, compared to 18.76% in 2012-2013.

-    In Washington, the rate of 12-17-year-olds who used marijuana in the past month dropped 0.89 percentage points from 10.06% in 2013-2014 to 9.17% in 2014-2015, compared to 9.81% in 2012-2013. The rate of past-year use dropped 1.92 percentage points from 17.53% in 2013-2014 to 15.61% in 2014-2015, compared to 16.48% in 2012-2013.

-    Nationwide, the rate of past-month marijuana use among 12-17-year-olds dropped 0.02 percentage points from 7.22% in 2013-2014 to 7.2% in 2014-2015, and the rate of past-year use dropped 0.42 percentage points from 13.28% to 12.86%.

The overall findings of the NSDUH are in line with those of the annual Monitoring the Future survey sponsored by the National Institute on Drug Abuse (NIDA), which were released last week and found little change in rates of teen marijuana use.
