Behavioral Health Trends 2014 Survey

Marijuana Use
As noted in the illicit drug use section, an estimated 22.2 million Americans aged 12 or older in 2014 were current users of marijuana. This number of past month marijuana users corresponds to 8.4 percent of the population aged 12 or older.  The percentage of people aged 12 or older who were current marijuana users in 2014 was higher than the percentages from 2002 to 2013. This rise in marijuana use among those aged 12 or older may reflect the increase in marijuana use by adults aged 26 or older and, to a lesser extent, increases in marijuana use among young adults aged 18 to 25 compared with the percentages of young adults who reported marijuana use in 2002 to 2009.
