The new party pill for teenagers is a popular sleeping pill.

Teens tell Local 10 it's called A-Minus. In your medicine cabinet, it's Ambien CR and Ambien.

And that's part of the problem. It's easy for young people to get the pills because millions of Americans already have them at home in their medicine cabinets.

"We're seeing a lot of young kids that instead of resorting to recreational drugs like alcohol, cocaine and heroin they're actually reverting to the medicine cabinet at home," said Dr. Nabil El Sandi at Broward General Hospital.

Ambien is commonly prescribed for people who have trouble falling asleep. It's a sedative hypnotic which means it affects the central nervous system.

And for young people who take the pills with alcohol, it can be deadly.

"If they take it with alcohol it could cause stupor, cause their respirations to drop, their breathing can slow down and even stop. They can actually die from it," said El Sandi.

The new fad is so serious that the United States Drug Enforcement Agency has Ambien listed at the top of its Web site, right after cocaine, crack cocaine, and rohypnol, the date rape drug.

In fact, emergency room physicians are also concerned that Ambien may be used on unsuspecting people and slipped into someone's drink as the new date rape drug, which can cause the victim to black out for as long as two days.

"They may have been sexually assaulted. Unknowingly and unwittingly while just trying to have fun," said El Sandi.

Dr. Scott Poland of the Nova Southeastern Drug Abuse Prevention and Treatment said that some teenagers are leading secret lives.

"Secret lives that have to do with sex, drugs and reckless behavior," he said.

One teen told Local 10 that he knows a lot of "pill heads."

If you're a parent, experts say you should watch for any significant changes in your teen's behavior, such as withdrawal or irritability.

And keep a close eye on the medicines you keep in your cabinet, experts say.
