Please Help!! My Cousin Is Addicted To Tramadol Addiction

My cousin brother is dependent on refnol and tramadol. His friends said he now takes as much as 8 tablets in a day. We couldn’t sleep all in the evening while he came home yesterday evening with spits dribbling down his shirt and talking gibberish. He’s destroyed so several things in the house. His mom is asthamatic, she’d a crisis yesterday evening when he started his weird behavior. Please who has fought this addiction before? How do we help him?
