Teens who drink more prone to opioid abuse

YALE (US) — Adolescents who smoke cigarettes or use alcohol or marijuana may be at greater risk for abuse of prescription opioids as young adults.

Researchers from Yale University believe the study, published in the Journal of Adolescent Health, is the first to demonstrate that early alcohol, cigarette, and marijuana use are all associated, to varying degrees, with a two- to-three times greater likelihood of subsequent abuse of prescription opioids.

Researchers from Yale University set out to determine whether certain tenets of the so-called “gateway hypothesis” applied to subsequent abuse of prescription opioids — specifically, whether substance use in the adolescent years was associated with later abuse of harder drugs.

They studied demographic and clinic data collected from 18- to 25-year-olds from the 2006-2008 National Survey on Drug Use and Health to determine the likelihood, based on their prior usage.

Their findings included:

  • 12 percent of the survey population of 18- to 25-year-olds reported current abuse of prescription opioids.
  • For this population, prevalence of previous substance use was 57 percent for alcohol, 56 percent for cigarettes, and 34 percent for marijuana.
  • In young men, previous abuse of all three substances was associated with an increased likelihood of subsequent opioid abuse during young adulthood, but only previous marijuana use carried this association among young women.

The study could lead to much more targeted efforts at prevention.

“Given that there are now an estimated three and a half million young adults who abuse prescription opioids and this number is growing, our study of the data shows that efforts to target early substance use may help to curb this increasing abuse of prescription opioids,” says lead author Lynn Fiellin, associate professor of medicine.

The study was supported by grants from the Robert Wood Johnson Physician Faculty Scholars Program, the National Institute on Drug Abuse, and the Department of Veterans Affairs in West Haven, Connecticut.
