Nicotine vaping tapers off among teens


 

Levels of nicotine and marijuana vaping among adolescents remain elevated but did not increase significantly in the past year, data from the annual Monitoring the Future survey show.

The 2020 survey included responses from 11,821 individuals in 112 schools across the United States from Feb. 11, 2020, to March 14, 2020, at which time data collection ended prematurely because of the COVID-19 pandemic. The results represent approximately 25% of the usual data collection.

A key positive finding in this year’s survey was the relatively stable levels of nicotine vaping from 2019 to 2020, following a trend of notably increased use annually since vaping was added to the survey in 2017.

During the years 2017-2019, the percentage of teens who reported vaping nicotine in the past 12 months increased from 7.5% to 16.5% among 8th graders, from 15.8% to 30.7% among 10th graders, and from 18.8% to 35.3% among 12th graders. However, in 2020, the percentages of teens who reported past-year nicotine vaping were relatively steady at 16.6%, 30.7%, and 34.5%, for 8th-, 10th-, and 12th-grade students, respectively. In addition, reports of daily or near-daily nicotine vaping (defined as 20 occasions in the past 30 days) decreased significantly, from 6.8% to 3.6% among 10th graders and from 11.6% to 5.3% among 12th graders.

“The rapid rise of teen nicotine vaping in recent years has been unprecedented and deeply concerning since we know that nicotine is highly addictive and can be delivered at high doses by vaping devices, which may also contain other toxic chemicals that may be harmful when inhaled,” said Nora D. Volkow, MD, director of the National Institute on Drug Abuse in a press release accompanying the release of the findings. “It is encouraging to see a leveling off of this trend though the rates still remain very high.”

Reports of past-year marijuana vaping remained similar to 2019 levels after a twofold increase in the past 2 years, according to the survey. In early 2020, 8.1%, 19.1%, and 22.1% of 8th, 10th, and 12th graders reported past-year use. However, daily marijuana vaping decreased by more than half from 2019, to 1.1% among 10th graders and 1.5% among 12th graders.

Past-year use of the JUUL devices specifically also declined among older teens, from 28.7% in 2019 to 20% in 2020 among 10th graders and from 28.4% in 2019 to 22.7% in 2020 among 12th graders.

Other trends this year included the increased past-year use of amphetamines, inhalants, and cough medicines among 8th graders, and relatively low reported use among 12th graders of LSD (3.9%), synthetic cannabinoids (2.4%), cocaine (2.9%), ecstasy (1.8%), methamphetamine (1.4%), and heroin (0.3%).

The findings were published in JAMA Pediatrics.

Early data show progress

“The MTF survey is the most referenced and reliable longitudinal study reporting current use of tobacco, drugs, and alcohol among young people,” said Mark S. Gold, MD, of Washington University, St. Louis, in an interview.

“The new data, collected before data collection stopped prematurely due to the COVID-19 pandemic, suggests that some progress is being made in slowing the increase in substance use among these, the most vulnerable,” he said.

“The best news was that nicotine vaping decreased significantly after its meteoric increase over the past few years,” Dr. Gold emphasized. “Past-year vaping of marijuana remained steady at alarming levels in 2020, with 8.1% of 8th graders, 19.1% of 10th graders, and 22.1% of 12th graders reporting past-year use, following a two-fold increase over the past 2 years.” The use of all forms of marijuana, including smoking and vaping, did not significantly change in any of the three grades for lifetime use, past 12-month use, past 30-day use, and daily use from 2019 to 2020.

“Teen alcohol use has not significantly changed over the past 5 years,” and cigarette smoking in the last 30 days did not significantly change from 2019 to 2020, said Dr. Gold. However, “as with adults, psychostimulant use is increasing. Past year nonmedical use of amphetamines among 8th graders increased, from 3.5% in 2017 to 5.3% in 2020.”

COVID-era limitations

“The data suggest that pre-COVID pandemic vaping, smoking cigarettes, marijuana, and alcohol use had stabilized,” Dr. Gold said. “However, it is very difficult to predict what the COVID era data will show as many young people are at home, on the streets, and unsupervised; while adult substance misuse, substance use disorders, and overdoses are increasing. Drug supplies and access have increased for alcohol, cannabis, vaping, and tobacco as have supply synthetics like methamphetamine and fentanyl.”

In addition, “access to evaluation, intervention, and treatment have been curtailed during the pandemic,” Dr. Gold said. “The loss of peer role models, daily routine, and teacher or other adult supervision and interventions may interact with increasing despair, social isolation, depression, and anxiety in ways that are unknown. “It will not be clear until the next survey if perceived dangerousness has changed in ways that can protect these 8th, 10th, and 12th graders and increase the numbers of never users or current nonusers.”

The Monitoring the Future survey is conducted each year by the University of Michigan’s Institute for Social Research, Ann Arbor, and supported by NIDA, part of the National Institutes of Health. Dr. Gold had no relevant financial conflicts to disclose.
