WEST PALM BEACH, Fla. (AP) - A survey shows overall drug use is down among Florida's middle and high school students, although marijuana use is a growing concern.

Use of alcohol, cigarettes and abuse of prescription stimulants and pain relievers saw reductions among the survey's measures of past 30-day drug use. Marijuana use, though, has increased. Survey officials say youth perception that marijuana is not harmful has increased.

Also alarming is the rate of alcohol use among Florida's students exceeds national figures.

The 2010 Florida Youth Substance Abuse Survey results were released Thursday at the Hanley Center, a nonprofit addiction treatment center in West Palm Beach.

The survey included 72,797 students in grades 6 through 12 and had a margin of error of plus or minus one percentage point.
