The Sullivan County Sheriff is warning the public that deputies have found marijuana laced with fentanyl in the county.



A deputy was patrolling the Walmart parking lot in the Town of Thompson Monday night when he spotted a car parked facing the wrong way in the crosswalk at the front entrance, according to a news release from Undersheriff Eric Chaboty.



When the deputy approached, the car, the driver became belligerent and tried to run inside the store, the news release says.



The 22-year-old Bloomingburg man was taken into custody and found in possession of seven grams of marijuana, police said.

Deputies tested the marijuana and found that it contained fentanyl, the powerful drug that has played a part in many overdose deaths.“We have been on the lookout for about a year,” Sullivan County Sheriff Michael Schiff said in the news release. “We can now confirm that it is here.” Detectives learned from the Bloomingburg man who relayed that the drug dealer he bought the marijuana from warned him that it was "very potent," according to the news release.“This is the stuff that is causing the majority of the overdoses,” Schiff said. “They are mixing fentanyl with heroin, cocaine and now marijuana. The results could be deadly.”
