Substance abuse by U.S. teenagers declined significantly this year, according to the results of a new national survey that found the use of prescription opioids by adolescents fell to the lowest level in nearly two decades.

Illicit drug use by 10th graders fell by nearly 12 percent in 2021, and by about 5% for eighth and 12th graders. The findings represent the largest one-year decline in illicit drug use by teens since the Monitoring the Future survey began in 1975.

The study by University of Michigan researchers found that teenagers reported increased feelings of boredom, anxiety, depression and loneliness in 2021 – no doubt fueled by pandemic-related fears and isolation. But unlike their adult counterparts, young people overall did not increase their use of marijuana, alcohol and other drugs.

“We have never seen such dramatic decreases in drug use among teens in just a one-year period. These data are unprecedented and highlight one unexpected potential consequence of the COVID-19 pandemic, which caused seismic shifts in the day-to-day lives of adolescents,” Nora Volkow, MD, Director of the National Institute on Drug Abuse, said in a statement.

“Moving forward, it will be crucial to identify the pivotal elements of this past year that contributed to decreased drug use – whether related to drug availability, family involvement, differences in peer pressure, or other factors – and harness them to inform future prevention efforts.”

The Monitoring the Future survey is given annually to students in eighth, 10th and 12th grades, who self-report their drug use behaviors and attitudes. The results from this year’s survey were collected from February through June 2021. Over 32,000 students enrolled in 319 public and private schools in the U.S. participated, with some taking the survey at home and others while at school.

The percentage of students who reported using any illicit drug other than marijuana within the past year decreased significantly. Among 12th graders, for example, 7.2% reported using an illicit drug in 2021, compared to 11.4% in 2020.

Decreases were also reported in the use of alcohol by 12th graders (46.5% in 2021 vs. 55.3% in 2020) and in marijuana (30.5% in 2021 vs. 35.2% in 2020).

Significant declines in use were also reported by students in 2021 for a wide range of drugs, including cocaine, heroin, hallucinogens, cigarettes and nonmedical use of amphetamines, tranquilizers, and prescription opioids.

The decline in drug use by teens is not a one-year fluke and is part of a long running trend. For example, the use of Vicodin by 12th graders has fallen by nearly 92 percent since its peak in 2003. The use of OxyContin has declined by 83% since its peak in 2005.   

“In addition to looking at these significant one-year declines in substance use among young people, the real benefit of the Monitoring the Future survey is our unique ability to track changes over time, and over the course of history,” said Richard Miech, PhD, who led the Monitoring the Future study at the University of Michigan. “We knew that this year’s data would illuminate how the COVID-19 pandemic may have impacted substance use among young people.”

Not all the news is good. The researchers found that adolescents who suffered severe stress, anxiety or depression due to the pandemic, experienced financial hardship, or whose parents used drugs were most likely to use drugs themselves.

Other studies have found that adults who regularly use recreational drugs increased their drug usage during the pandemic. A new study of alcohol sales in 16 U.S. states found a major increase in wine and liquor sales in the first few months of the pandemic, by as much as 20 to 40 percent in some states.

Another recent study found that opioid prescribing briefly increased in the early stages of the pandemic, as patients postponed corrective procedures and it became harder to obtain non-opioid therapies for pain such as massage and physical therapy. Opioid prescribing returned to previous levels after a few months.   

The CDC announced last month that the U.S. has seen over 100,000 drug deaths in the 12-month period ending in May, 2021. The record-high spike in overdoses is thought to be primarily a result of pandemic lockdowns and the continuing spread of illicit fentanyl.
