NORRISTOWN, Pa (CBS) — For the first time in Montgomery County, prosecutors got a conviction in a case involving a store operator selling synthetic marijuana, also known as K2.

26-year-old Mohamed Himed worked behind the counter at the Achi Store along High Street in Pottstown. On Tuesday, he pleaded guilty to charges that include corrupt organizations and possession with intent to deliver a controlled substance and possession with intent to deliver drug paraphernalia.

Prosecutor Kevin Steele says the investigation began after a man who allegedly bought the synthetic drugs from the store was involved a fatal crash in May, 2012.

“We have a case here where somebody has used this drug and then driven a car and killed two people,” Steele says, “so I believe the message is that K2 kills and did in this case.”

Police executed a search warrant at the store where they confiscated vials of K2, along with crack pipes, cash and a handgun.

Himed is facing significant jail time. The store owner, Rafie Ali, is still awaiting trial on identical charges.

The legislature made synthetic drugs illegal in 2011.
