Subutex

He was a Subutex addict. Subutex is supposedly used to wean people off heroin but, from what I have seen, there are more Subutex addicts in jail than there are heroin addicts (and there are a lot of heroin addicts).

She'd seen a doctor who’d prescribed Subutex, a drug-replacement treatment designed to wean the user off heroin. It had made her throw up. I was so relieved and told her how proud I was of her for taking control.
