A new report being released Tuesday says alcohol and drug use among teens is on the rise.
"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 study shows the number of teens in high school who reported drinking alcohol rose 11 percent last year. Six and a half million teens reported alcohol use -- about 39 percent of teens.
The survey also found that 25 percent of teens smoked marijuana last year. That is up from 19 percent.
The number of kids using pot and alcohol had been on a steady decline since 1998.
"The behavior I saw people go through - and to see how far people can fall - really turned me away more than anything else," Stacy Laskin, a 21-year-old senior in college, said in an interview with The Associated Press.
