K2 is a powerful herb purchased on the web.

Most people don't know about, but anyone can get their hands on it.

"Shocked how easy it is for anyone to buy this, especially not knowing the hazard of it," said Nia Earp, a junior at Valdosta State University.

And that's one of the dangers of K2--- the unknown.

Investigators say it's not only hazardous but dangerous.

"[It's] a blend of spices that combined give the effects of THC, which is in marijuana," said Alan Mann, a drug investigator, with the Lanier County Sheriff's Office.

K2, or synthetic marijuana, was outlawed in May by Governor Sonny Perdue.

It's also known as genie, spice and potpourri.

But officers say it's still sold at convenience stores.

Cook County deputies arrested Ketry Miller, 24, for having K2 on August 30.

And Lanier investigators nabbed Daniel Wilcox, 20, and Marqui Jordan, 20, for allegedly having 120 grams of it.

Both men were arrested at a traffic stop on August 12.

Its accessibility makes it a major concern for law enforcement.

"Teenagers are ordering it off the internet," said Mann. "It comes out of Peru. It's hard to intercept."

Deputies fear the drug has severe side effects.

"Extreme paranoia, they hallucinate very bad," said Mann. "There's been many cases where they've had to go to the hospital."

"I don't wanna try it if I don't know what the side effects are," said Josh Lee, a junior at VSU. "I mean most people know what the side effects of marijuana are. You never heard of anyone die from marijuana. This stuff you don't really know about."

K2 is illegal in 10 states.

In Georgia, it's listed as a schedule one controlled substance, along with heroine.

But the herb is still legal in Florida.
