MORGAN CITY, La. — In their work to keep drugs off the streets in St. Mary Parish, Louisiana, officials say they have made a few arrests in past days with something they don’t see very often around there - “Gray Death.”

According to the St. Mary Parish Sheriff's Office, "Gray Death" is a lethal combination of some of the most deadly opioids including heroin, fentanyl, and various fentanyl analogues. It is reported to have a potency 10,000 times greater than morphine.

The super drug began to surface in the south in Alabama and Georgia, officials say.

"A minuscule amount of this drug, which has the appearance of small chunks of concrete, can kill," the SMPSO said.

The sample in the photos was recovered from suspects that were traveling across St. Mary Parish from the Lake Charles area.

The public is advised to never pick up or touch this drug if you ever encounter it and to call and report it to law enforcement.
