I think they tell you how to ween yourself off it in the movie Trainspotting:

Relinquishing junk. Stage one, preparation. For this you will need one room which you will not leave. Soothing music. Tomato soup, ten tins of. Mushroom soup, eight tins of, for consumption cold. Ice cream, vanilla, one large tub of. Magnesia, milk of, one bottle. Paracetamol, mouthwash, vitamins. Mineral water, Lucozade, pornography. One mattress. One bucket for urine, one for feces and one for vomitus. One television and one bottle of Valium, which I've already procured from my mother, who is, in her own domestic and socially acceptable way also a drug addict. And now I'm ready. All I need is one final hit to soothe the pain while the Valium takes effect.

...wait, maybe he was talking about heroin.
