Lantana Police Department trying to get synthetic marijuana off the shelves

LANTANA, Fla. - It's legal, it's on store shelves across South Florida and it produces a high like marijuana.

It is called synthetic marijuana and it is sold under names like "Mr. Nice Guy."

Now, the Lantana Police Department is trying to put the brakes on its sale.

Officer Nelson Berrios is taking his fight to the streets. "We are notifying the individual convenience stores abut the dangers of this herbal incense," explains Berrios.

Experts say the effects are anything but nice.

"We're seeing youngsters and adults with tremendous after effects like headaches, nausea and even comas," adds Berrios.

Synthetic marijuana or K2 is a variation of unregulated dried plants that are crushed to look like tobacco.

So the Lantana Police Department is asking convenience store owners to voluntarily stop selling it.

The manager of the BP on Hypoluxo Road in Lantana agreed to do so.

"We don't want to be responsible for harming people," says Sudnar Joshi.

Some states have already passed laws prohibiting the sale or possession of the product.
