With school out and less to keep kids busy, many teenagers have a lot more free time on their hands. Unfortunately, experts say some are using their summer break to experiment with drugs. Some could be in your medicine cabinet or bought right over the counter.

"You do it to feel better; you do it to try something new, you're curious."

That's how 18-year-old Emily Schultz got hooked on the drug Oxycontin when she was 15. She's also tried Adoral, Ecstasy, cigarettes and marijuana.

Emily learned about Oxycontin when Jack Osborne, son of rocker Ozzy Osborne, talked about his addiction on MTV.

"I saw the name on one of my mom's prescription bottles a long time ago, and I just remember and thought, hey, let's try it. He kinda laid it all out for me what you do on the TV and I just followed the easy steps."

Certified prevention professional Sue Nowak says teens are becoming more creative in their drug use.

"They're actually using a whole lot of different narcotic medications, a whole group of different types of pills from uppers and downers underneath that we've got cocaine, meth and inhalants that actually a lot of kids start using in the summertime."

Sue says some drugs like the herb salvia divinorum are legal and can be purchased just like tobacco products. We went into one store to see just how available it is.

Newschannel 7 bought the hallucinogenic drug called salvia at a local headshop where you can also find drug paraphernalia and smoking pipes. You only have to be 18 to buy it and they didn't even check my ID, but they did give me a handout telling me the drug's effects.

The sheet explains salvia can cause altered light perception and uncontrolled fits of laughing. It warns not to drive or be taking care of people while on it. Again, it's sold legally in Wisconsin to anyone 18 and older.

"A lot of kids tell me it can be very, very intense, sometimes very scary experience. We don't have a lot of information on what it's doing to the development of the brain," says Nowak.

Emily knows drugs are out there and easy to get hold of in Wausau, but she's learned her lesson and says they're not anywhere in her future plans.

"I want to go to Milwaukee and get a masters in art, then eventually head out to Boston and open up my own gallery."

The Federal Drug Enforcement Administration is calling salvia divinorum "a drug of concern." Although it can be purchased over the counter, it has been compared to the illegal narcotic LSD.
