LEXINGTON, Ky. –  Concerns are rising in Lexington over the use of synthetic marijuana. Lexington Police say mostly juveniles and the homeless are using the drug, also known as serenity.

Sergeant Jervis Middleton says the drug is popular likely because it’s cheap and easy to get. Although it looks like marijuana, it is much different and very dangerous.

“Just like with any drug, you just don’t know what’s in it,” Sgt. Middleton explained. “The manufacturer of this drug… they’re just putting in whatever they deem necessary. They’re just trying to escape some of the KRS laws, some of the statutes, around trafficking or possession of the synthetic marijuana. You just don’t know what you’re getting in it, and that’s the dangerous part of it.”

Symptoms of synthetic marijuana usage include being lethargic, having hallucinations, sweating, and being rendered unconscious.
