How Many Teens Abuse Marijuana?

You are here

Some people mistakenly believe that “everybody’s doing it” and use that as an excuse to start using marijuana themselves. Well, they need to check the facts, because that's just not true. According to NIDA's 2012 Monitoring the Future study, about 6.5% of 8th graders, 17.0% of 10th graders, and 22.9% of 12th graders had used marijuana in the month before the survey. In fact, marijuana use declined from the late 1990s through about 2007. Unfortunately, this trend appears to be reversing. Since 2007, annual, monthly, and daily marijuana use increased among 10th and 12th graders while daily use increased among 8th graders. In 2012, 6.5% of 12th graders reported using marijuana daily, compared to 5.1% in 2007.
