Thirteen people have been indicted in four separate but related incidents involving drug trafficking and gun violations.
The FBI said the people sold heroin and Molly in the Pittsburgh area. The 13 allegedly brought the drugs into the area from other states, mainly New York and New Jersey.
Molly is a party drug marketed as Ecstasy, but the kind that was turning up on Pittsburgh streets was much more powerful than the normal E tablets.
“It was tested at 90 percent purity for methamphetamine," said Mike Christmas of the FBI.
FBI investigators used wiretaps to bust up two major drug rings run by violent gang members who were slinging Molly and heroin.
"It's coming in high potencies and poses a great risk. Many people consider it a party drug. It's far from that, and we're very grateful for all the work that's been done to bring these two organizations down,” said U.S. attorney David Hickton.
Eleven people were arrested and two are still on the run. They all face federal charges.
