Alcohol and marijuana use among teens is on the rise, ending a decade-long decline, a study being released Tuesday found.
"I'm a little worried that we may be seeing the leading edge of a trend here," said Sean Clarkin, director of strategy at the Partnership for a Drug-Free America, which was releasing the study. "Historically, you do see the increase in recreational drugs before you see increases in some of the harder drugs."
The annual survey found the number of teens in grades nine through 12 who reported drinking alcohol in the last month rose 11 percent last year, with 39 percent — about 6.5 million teens — reporting alcohol use. That's up from 35 percent, or about 5.8 million teens, in 2008.
For pot, 25 percent of teens reported smoking marijuana in the last month, up from 19 percent.
Until last year, those measures for pot and alcohol use had been on a steady decline since 1998, when use hovered around 50 percent of teens for alcohol and 27 percent for pot.
The study also found use of the party drug Ecstasy on the rise. Six percent of teens surveyed said they used Ecstasy in the past month, compared with 4 percent in 2008.
If parents suspect their teen is using, they need to act quickly, Mr. Clarkin said. Monitor them more closely, talk with them about drugs, set rules and consult outside help, such as a counselor, doctor, clergy or other resource, he said.
The researchers asked teens how they felt about doing drugs or friends who did them. The study found a higher percentage of teens than in the previous year agreed that being high feels good; more teens reported having friends who usually get high at parties; and fewer teens said they wouldn't want to hang around others who smoked pot.
Stacy Laskin, now 21 and a senior in college, said marijuana was everywhere during her high school years. She said she tried pot and drank alcohol in high school but didn't make it a habit like other teens she knew.
"The behavior I saw people go through — and to see how far people can fall — really turned me away more than anything else," Miss Laskin said in an interview with Associated Press.
Her close friend from high school died in 2008 from a heroin overdose. Miss Laskin, a psychology major at Salisbury University in Maryland, was so torn by her friend Jeremy's death that she decided to help others and is working on her second internship at a drug-treatment center.
"Just seeing the negative impact made me want to get involved," she said.
• Teen abuse of prescription drugs and over-the-counter cough medicine remained stable from 2008 to 2009. About one in seven teens reported abusing a prescription pain reliever in the past year, and about 8 percent of the teens questioned reported over-the-counter cough medicine abuse in the past year.
• Teen steroid and heroin use remained low at 5 percent for lifetime use.
The group's "attitude tracking" study was sponsored by MetLife Foundation. Researchers surveyed 3,287 teens in grades nine through 12. Data were collected from questionnaires that teens filled out anonymously from March to June 2009. The study has a margin of error of 2.3 percentage points.
