Teen Marijuana Use Falls as More States Legalize

That’s the big take-home from the 2014 Monitoring the Future study by the University of Michigan and the National Institutes on Drug Abuse, which was released Tuesday morning. The MTF is an annual survey of 40,000 8th-graders, 10th-graders and 12th-graders. It’s notable both for its size and for the fact that it was conducted this past spring, in the midst of a nationwide conversation about drug reform in the run-up to the midterm elections. Here’s what the survey found:

Marijuana use? Down. Alcohol use? Way down. Cigarettes? Waaay down. Fewer than 15 percent of 12th-graders reported using cigarettes any time in the past month, down from well over 35 percent in the late 1990s. Monthly alcohol use dropped from nearly 55 percent of 12th-graders in 1992 to less than 40 percent in 2014. Even weed, which has been on a flatter trajectory since the 1990s than the other substances, is down year over year.

These numbers comport with findings earlier this year from the National Survey on Drug Use and Health, the government’s other major substance use barometer.

Even better news is that frequent, daily use — which experts agree is the most harmful to developing young minds — is also down considerably. Cigarettes posted the sharpest drop in daily use, falling from nearly 25 percent of 12th graders in 1997 to about 7 percent in 2014. Frequent alcohol use has declined, although less dramatically. Frequent marijuana use had been on a slight rise for roughly the second half of the 2000s, but since about 2011 it’s either held steady or fallen.

“Both alcohol and cigarette use in 2014 are at their lowest points since the study began in 1975,” the study’s authors conclude in a press release. The National Institutes of Drug Abuse agrees: “with marijuana use appearing to level off, and rates of many other drugs decreasing, it is possible that prevention efforts are having an effect,” said director Nora D. Volkow in a release.
