The 2016 Monitoring the Future (MTF) annual survey results released today from the National Institutes of Health (NIH) reflect changing teen behaviors and choices in a social media-infused world. The results show a continued long-term decline in the use of many illicit substances, including marijuana, as well as alcohol, tobacco, and misuse of some prescription medications, among the nation’s teens. The MTF survey measures drug use and attitudes among eighth, 10th, and 12th graders, and is funded by the National Institute on Drug Abuse (NIDA), part of the NIH. Overall, 45,473 students from 372 public and private schools participated in this year’s MTF survey.

Findings from the survey indicate that past year use of any illicit drug was the lowest in the survey’s history for eighth graders, while past year use of illicit drugs other than marijuana is down from recent peaks in all three grades. Marijuana and e-cigarettes are more popular than regular tobacco cigarettes.

The survey also shows that there continues to be a higher rate of marijuana use among 12th graders in states with medical marijuana laws, compared to states without them. For example, in 2016, 38.3 percent of high school seniors in states with medical marijuana laws reported past year marijuana use, compared to 33.3 percent in non-medical marijuana states, reflecting previous research that has suggested that these differences precede enactment of medical marijuana laws.

A large drop in the use of tobacco cigarettes was seen in all three grades, with a long-term decline from their peak use more than two decades ago. For example, in 1991, when MTF first measured cigarette smoking, 10.7 percent of high school seniors smoked a half pack or more a day. Twenty-five years later, that rate has dropped to only 1.8 percent, reflecting the success of widespread public health anti-smoking campaigns and policy changes.

There has been a similar decline in the use of alcohol, with the rate of teens reporting they have “been drunk” in the past year at the survey’s lowest rates ever. For example, 37.3 percent of 12th graders reported they have been drunk at least once, down from a peak of 53.2 percent in 2001.

“Clearly our public health prevention efforts, as well as policy changes to reduce availability, are working to reduce teen drug use, especially among eighth graders,” said Nora D. Volkow, M.D., director of NIDA. “However, when 6 percent of high school seniors are using marijuana daily, and new synthetics are continually flooding the illegal marketplace, we cannot be complacent. We also need to learn more about how teens interact with each other in this social media era, and how those behaviors affect substance use rates.” / Press Release: University of Michigan/Michigan News
