"Choose life. Choose a job. Choose a career. Choose a family. Choose a fucking big television, Choose washing machines, cars, compact disc players, and electrical tin can openers. Choose good health, low cholesterol and dental insurance. Choose fixed-interest mortgage repayments. Choose a starter home. Choose your friends. Choose leisure wear and matching luggage. Choose a three piece suite on hire purchase in a range of fucking fabrics. Choose DIY and wondering who the fuck you are on a Sunday morning. Choose sitting on that couch watching mind-numbing spirit-crushing game shows, stuffing fucking junk food into your mouth. Choose rotting away at the end of it all, pissing your last in a miserable home, nothing more than an embarrassment to the selfish, fucked-up brats you have spawned to replace yourself. Choose your future. Choose life . . . But why would I want to do a thing like that? I chose not to choose life: I chose something else. And the reasons? There are no reasons. Who needs reasons when you've got heroin?
People think it's all about misery and desperation and death and all that shite, which is not to be ignored. But what they forget is the pleasure of it. Otherwise we wouldn't do it. After all, we're not fucking stupid. At least, we're not that fucking stupid. Take the best orgasm you ever had, multiply it by a thousand and you're still nowhere near it. When you're on junk you have only one worry: scoring. When you're off it you are suddenly obliged to worry about all sorts of other shite. Got no money: can't get pissed. Got money: drinking too much. Can't get a bird: no chance of a ride. Got a bird: too much hassle. You have to worry about bills, about food, about some football team that never fucking wins, about human relationships and all the things that really don't matter when you've got a sincere and truthful junk habit."
