Two Northeast Philadelphia locations were busted yesterday in Pennsylvania’s “Operation Artificial High,” a statewide sweep for synthetic marijuana.

Search warrants went out across the state, but in Philadelphia, South Street and the Northeast yielded the biggest return for law enforcement officials.

Several boxes of the substance were recovered at a smoke shop on the 10000-block of Verree Road, and drug paraphernalia was found at a gas station on the 9100-block of Frankford Avenue.

Pennsylvania has a ban on synthetic marijuana.
