Results from the 2016 edition of the Monitoring the Future survey find that marijuana use by 8th-graders and 10th-graders is declining year by year. Further, a greater percentage of younger teens now say that their ability to obtain marijuana is more difficult than ever before.
Marijuana use patterns among 12th-graders have held steady since 2011, the survey reported.
Approximately 50,000 students are surveyed annually as part of the University of Michigan study.
Since the mid-1990s, self-reported lifetime use of cannabis has fallen 44 percent among 8th-graders, 30 percent among 10th-graders, and ten percent among 12th-graders. Twenty-nine states have legalized the medical use of cannabis, and eight of those states have also regulated the adult use of marijuana, since that time.
Overall, teens’ self-reported use of alcohol and/or any illicit substance aside from marijuana is at a historic low.
