Findings from the 2019 Monitoring the Future (MTF) survey demonstrate the appeal of vaping to teens, as seen in the increased prevalence of marijuana use as well as nicotine vaping. Results from the 45th annual MTF survey, a nationally representative sample of eighth, 10th and 12th graders in hundreds of U.S. schools, were announced by the director of the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health (NIH), along with the University of Michigan scientist who leads the research team. The self-report survey is given annually to students who respond to questions about their drug use and attitudes.
Past year vaping of marijuana, which has more than doubled in the past two years, was reported at 20.8% among 12th graders, with 10th graders not far behind at 19.4% and eighth graders at 7.0%. Past month marijuana vaping among 12th graders nearly doubled in a single year to 14% from 7.5% – the second largest one-year jump ever tracked for any substance in the history of the survey. (The largest was from 2017-2018 with past month nicotine vaping among 12th graders).
For the first time, the survey measured daily marijuana vaping, which was reported at 3.5% among 12th graders, 3.0% among 10th graders, and 0.8% among eighth graders. The MTF investigators documented more detailed findings on teen vaping of marijuana in a research letter released today in the Journal of the American Medical Association. High rates of nicotine vaping reported in the MTF survey were released in September.
Marijuana continues to be the most commonly used illicit drug by adolescents. After remaining mostly stable for many years, daily use of marijuana went up significantly since 2018 among eighth and 10th graders – now at 1.3% and 4.8% respectively. However, overall past year marijuana use rates remain steady among teens (35.7% among 12th graders; 28.8% among 10th graders; and 11.8% among eighth graders).
Past year rates of any illicit drug use, other than marijuana, remain relatively low among 12th graders; past year use was 3.6% for LSD; 3.3% for synthetic cannabinoids; 2.2% for both cocaine and MDMA (ecstasy); and 0.4% for heroin. Other drug use, including the misuse of prescription medicines and the use of alcohol as well as tobacco cigarettes, continues to decline.
“We are heartened to see the continuing decline in the use of many drugs, particularly non-medical use of prescription opioids; however, teens are clearly attracted to vaping products, which are often concentrated amounts of drugs disguised as electronic gadgets,” said NIDA Director Dr. Nora Volkow. “Their growing popularity threatens to undo years of progress protecting the health of adolescents in the U.S.”
Use of regular cigarettes continues to decline among teens, especially among 12th graders who had a significant decline in past month use, now at 5.7%, down from 7.6% last year and 13.6% five years ago.
In 2019, 2.4% of 12th graders said they smoked cigarettes daily, a significant decline from 3.6% in 2018. However, 11.7% said they vaped nicotine daily in 2019, the first year daily vaping use has been measured.
One in four 12th graders say they vaped nicotine in the past month, along with 1 in 5 10th graders, and nearly 1 in 10 eighth graders. Many teens say they vape for the flavor, to experiment, for social reasons, or to feel good. However, from 2018-2019, the number of 12th graders saying they vape because they are “hooked” more than doubled to 8.1%, up from 3.6%. It is important to note that not all teens know what is in the products they are vaping.
