Parents' View of Teen Drug Use: Your Kid, Not Mine

Survey Shows Parents Underestimate Their Own Teens' Use of Alcohol and Marijuana

Sept. 15, 2011 -- When it comes to parents thinking about their own teens, they often put blinders on. A national poll finds that parents underestimate the likelihood that their own teenager has used alcohol or marijuana, while overestimating the drug use of other teens.

One in 10 parents surveyed believed their own teenage child had used alcohol during the previous year. And just one in 20 believed their teen had smoked marijuana.

Teens themselves reported a much higher rate of substance use in a separate poll released late last year. About half of 10th-graders said they had used alcohol over the previous 12 months; about one in 4 (28%) reported marijuana use.

More than half of the parents polled in the latest survey believed general alcohol use among teens -- other than their children -- was higher than reflected in the earlier poll and about a third overestimated marijuana use among other teens.

Parents in Denial About Drug Use?

The seeming disconnect suggests a need for better communication between parents and their teenaged children about drug use, but it doesn't necessarily mean parents are in denial or oblivious to abuse issues, says study researcher Bernard Biermann, MD, PhD, of the University of Michigan's C.S. Mott Children's Hospital.

"When teens report that they have used substances, it could mean having a beer at a party six months ago," he tells WebMD. "We really can't say to what extent parents are missing chronic substance use."

The survey included a nationally representative group of parents with children between the ages of 13 and 17.

Among the major findings:

  • 10% of the parents believed their teen had used alcohol within the past year; 15% reported that they were not sure about their child's alcohol use.
  • Parents of older teens were far more likely to report that their child might be using alcohol or marijuana. Among the parents of 17-year-olds, 23% believed their child had used alcohol and 10% believed their child had used marijuana. Just 3% of parents with 13- and 14-year-olds believed their child might be using the substances.
  • About a third of parents surveyed estimated the percentage of 10th-graders who used alcohol to be 60% or greater, while about half believed that marijuana use among the nation's 10th-graders was 40% or higher.
