A dangerous drug is appearing on the streets in York County for the first time, and it's landed two people in jail this week.

Members of York County's multi-jurisdictional drug enforcement unit have found MDMA, which is the pure powder form of ecstasy.

"This is the pure stuff.  This is what people want to get their hands on if they can," said Fort Mill drug unit Commander Walter Beck.

On Wednesday, agents said they found the drug in the hands of a Fort Mill teenager.  They've charged 17-year-old Mitchell Poindexter with possession with intent to distribute MDMA, marijuana and also LSD.

Investigators are now looking into how the teenager got a hold of the drug -- a drug that they are suddenly seeing in the county.

Beck said Poindexter lives in a well-to-do Fort Mill neighborhood, and like many teenagers, isn't selling drugs to make money.

"They're just doing it for sport," he said. "Because it's fun."

Thursday in Rock Hill, narcotics officers made another arrest.  They said they found 38-year-old Eric Artice with 108 doses of MDMA. 

Artice is no stranger to law enforcement.  He served 10 years in federal prison for selling crack.  He was released in 2009, and placed in a supervised federal release program.  One condition of that program allows officers to search his house, car and belongings at any time without a warrant. That's how the drugs were found, investigators said.

"He had a job, he had a family to live with.  I don't understand it," Beck said.

Neither do neighbors on Kestrel Drive who told Channel 9 that Artice lived with his grandparents.

"They're nice people, good people," said Kay Horne.  "There was never anything out of the ordinary over there. I'm really surprised."

Narcotics agents are finding the powdered ecstasy is being funneled into capsules to disguise its identity.

"It's camouflage," Beck said. "People will say, 'Oh, that's vitamins,' or 'That's medication.'”   

Beck worries the most about the risks buyers are taking, using a drug that could have anything in it.

"You're trusting that person that what they're selling you isn't gonna kill you, isn't gonna put you in the hospital. All they care about is the money," he said.
