The rate of current marijuana use among Colorado teens decreased significantly last year and is now lower than it was prior to the state’s legalization of marijuana for adult use, according to survey data published on Monday.
The rate of past-month marijuana use by individuals ages 12 to 17 dropped nearly 20 percent from 11.3 percent in 2014-2015 to 9.08 percent in 2015-2016, according to the National Survey on Drug Use and Health performed by the Substance Abuse and Mental Health Services Administration.
Officials say it is now lower than it was in 2011-2012 (10.47 percent) and 2012-2013 (11.16 percent).
For state-level data, the survey uses pooled two-year periods to increase sample sizes and statistical accuracy. Last year the survey showed that Colorado was ranked No. 1 in the nation on adolescent marijuana use.
