ORANGE COUNTY, Fla. -- A natural herb as potent as LSD is showing up on local school campuses. It's called Salvia and disturbing video shows how it affects young people.

Salvia is smoked through a bong and the effects kick in right away. University of Central Florida student Joel Birsch said he tried it because it's legal.

The video of his 10-minute high is disturbing to watch. He wrestled a friend to the ground. Then, Birch threw himself down a staircase. He dislocated his shoulder. He watched the video and admitted he even hallucinated.

"I thought I was a Ninja Turtle," he said. "I though I was (rap artist) 50-Cent."

Commander Gil McDaniel with the narcotics unit at the Orange County Sheriff's Office said this herb should not be legal.

"If you think you're a Ninja Turtle and you throw yourself down the steps, that should be your first clue something's wrong," said Commander McDaniel.

Ten countries including Australia, Belgium, Denmark, Finland, Israel, Italy, Norway, Poland, South Korea and Sweden have criminalized Salvia.

In the U.S., Salvia is illegal in Louisiana, Missouri, Tennessee, Delaware, and Oklahoma. Legislation is being considered in New York, Illinois, Alaska and California. But in Florida, there is no law.

"I'm not worried about it 'cause I didn't do anything illegal or anything," said Birch. But McDaniel counters by saying, "What's amazing is the stupidity of people who say, 'It's legal so it's okay.'"

The sheriff's office would like to see legislation passed in Florida to make Salvia illegal.

And Birch says after watching the video of his high, "I probably wouldn't do that again."

Salvia is an herb sold in Mexico. It's also called Salvia Divinorum or Sage. There are reports of people smoking salvia and being so reckless they killed themselves. In Florida, you have to be 18 years old to legally buy the herb.
