Picked up some Molly did .20 and rolled, did make me nauseous but I had been nauseous all day. The next day my guy calls me and says he tested it and it has fentanyl in it. We've been friends for a while and he knows it's good MDMA but wanted me to know it did test positive for fentanyl. He will take it back but I'm just wondering how many of you would keep using it?
