Big Declines in Substance Abuse, Delinquency Among U.S. Teens

Survey data over more than a decade show that teens are far less likely to abuse alcohol, nicotine and illicit drugs, and are less likely to engage in delinquent behaviors, such as fighting and stealing.
Researchers at Washington University School of Medicine in St. Louis analyzed data from the National Survey on Drug Use and Health, an annual survey of 12- to 17-year-olds from all 50 states. The data included information from 2003 through 2014, the last year for which survey numbers are available. A total of 210,599 teens — 13,000 to 18,500 each year — were part of the study.
The investigators found that the number of substance-use disorders among 12- to 17-year olds had declined by 49 percent over the 12-year span, along with a simultaneous 34 percent decline in delinquent behaviors, such as fighting, assault, stealing, selling drugs or carrying a handgun.
The reduction in substance abuse among teens parallels findings in other recent surveys, but until now no one has looked at how the drop-off may be linked to other behavioral issues.
The article appears in the journal Psychological Medicine.
“We’ve known that teens overall are becoming less likely to engage in risky behaviors, and that’s good news,” said first author Richard A. Grucza, PhD, a professor of psychiatry.
“But what we learned in this study is that the declines in substance abuse are connected to declines in delinquency. This suggests the changes have been driven more by changes in adolescents themselves more than by policies to reduce substance abuse or delinquent behavior.”
Although heroin and opioid abuse have become epidemic in many areas of the United States, the use among teens has fallen, according to the survey data.
“Opioid problems continue to increase among adults,” he said. “But among the 12- to 17-year-old population, we saw a drop of nearly 50 percent.”
Based on the survey data, Grucza and his team estimated that in 2014 there were nearly 700,000 fewer adolescents with substance-use disorders than in 2003.
