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.
