The results of the Monitoring the Future Survey invalidate claims by prohibitionists that liberalizing cannabis laws will increase teen usage. The survey was funded by the National Institute on Drug Abuse
According to the survey:
• Among 8th-graders, the rate of past-year cannabis use dropped significantly from 11.8% in 2015 to 9.4% in 2016; its lowest level since 1993. Past-month cannabis use also dropped significantly; from 6.5% in 2015 to 5.4% in 2016, and daily use dropped from 1.1% in 2015 to 0.7% in 2016.
• Among 10th- and 12th-graders, rates of past-year, past-month, and daily cannabis use remained relatively stable compared to last year.
