Last decade saw big decrease in teens who used commonly prescribed and misused prescription drugs

Since 2009, U.S. high school seniors have reported steep declines in medical use, misuse and availability of the three most commonly prescribed and misused controlled substances for teens, a new University of Michigan study found. 

 

Researchers compared use trends, sources and perceived availability of opioids, stimulants and benzodiazepines from 2009 to 2022. The research letter detailing the findings is scheduled to appear July 24 in JAMA, the Journal of the American Medical Association.  

 

“To put these findings in context, the reduction over the past decade was like going from 1 in every 9 high school students using prescription drugs nonmedically down to 1 in every 40 high school students,” said Sean Esteban McCabe, U-M professor of nursing and director of the Center for the Study of Drugs, Alcohol, Smoking and Health.  

 

“While this decrease is encouraging, we need to be vigilant because any amount of nonmedical use poses risks, especially with the danger posed by counterfeit pills.”

 

Other findings from 2009 through 2022: 

• Lifetime medical use decreased from 24% to 16%. 
• Past-year misuse declined from 11% to 2%.
• The percentage of adolescents who reported being given prescription medications by friends or buying them from friends, both fell by more than half. 
• In 2009, adolescents who reported misusing prescription medications said the most common source was friends. Now, it is one’s own prescription (37%).
• Among adolescents who reported misuse, those with multiple sources for obtaining prescription medications dropped from 56% to 29%.
• Perceived difficulty of obtaining prescription medications for misuse declined across the three drug classes.
• The percentage of adolescents who reported that they thought it would be impossible to get prescription drugs for misuse increased from 36% to 49%. 

 

School closures during COVID accounted for the largest changes because students had limited contact with each other, and opportunities to sell or give away prescription drugs to friends declined, McCabe said.

 

Study co-author Philip Veliz, research associate professor of nursing, said the declines may be partially due to changes in prescribing practices, especially for opioids. The study did not examine specific trends based on drug class. 

 

“Prescribing practices have changed dramatically because we had an opioid epidemic, which turned into a heroin epidemic, and we’re still reeling from that, especially with fentanyl,” Veliz said. “A lot of this also has to do with parents having better knowledge and oversight of these medications.”

 

The steep decline in teens who misused prescription medications in the past year, from 11% to 2%, surprised researchers.

 

“That’s a massive decline. It used to be 1 in 9 kids, now it’s an incredibly rare event at this point,” Veliz said. “The second surprise was that … nearly half of kids say it’s probably impossible to get these drugs if they want to use them nonmedically right now. That’s a big chunk of the adolescent population, and this is just off the table.” 

 

Another surprise is that the landscape has not returned to what it looked like before COVID, McCabe said. 

 

“Adolescents have found it more difficult to obtain prescription stimulants for nonmedical use in recent years, which is a positive sign,” he said. “There needs to be more attention on stimulant use and diversion, and our team is currently working on such studies to help inform clinical guidelines for ADHD and stimulant use disorder.”

 

This study was supported by the National Institute on Drug Abuse, and used data from 12th grade students collected in 2009 through 2022 from the Monitoring the Future study, an annual survey at University of Michigan that tracks student substance use and other related trends.
