NAPLES, Fla.-  Ever heard of K2, Spice, Magic Mint, or Vanilla Sky?

If you haven't, you're not alone. But teens across the country, and across the state, are getting their hands on these new drugs. Police in Southwest Florida are warning parents about what to look for.

One of the most popular new drugs is called Salvia. It's a hallucinogenic, also known as Magic Mint or Sally-D. It's been made even more popular by a recent YouTube video that shows teen icon Miley Cyrus taking hits, and erupting in laughter. It can have the same effects as LSD or PCP, and it can alter your child's brain long after they use the drug.

Two other drugs are gaining popularity, too. Bath salts, and K2, or synthetic marijuana. Both were recently banned in Florida, but police admit it's still readily available. Even scarier, they won't even show up on a drug test.

Experts say always talk to your kids. Also, let them know that you know about these drugs and the harmful side effects.
