In 2016, rates of marijuana use among the nation’s 12- to 17-year-olds dropped to their lowest level in more than two decades, according to federal survey datareleased this week.
Last year, 6.5 percent of adolescents used marijuana on a monthly basis, according to the latest National Survey on Drug Use and Health. That represents a statistically significant drop from 2014, when the nation’s first recreational marijuana shops opened in Washington state and Colorado.
The last time monthly teen marijuana use was this low was 1994, according to the survey.
