I was at a party once, which I didn't really want to be at but didn't really have a choice, and everyone was taking drugs and I was hiding in the corner. I started speaking to the only other guy who was also hiding in the corner and it turned out he was a heroin addict. He was quite open about it. He was talking about his life, and after about half an hour of him talking I thought, "this guy had no chance."

I mean, I grew up in a lower-middle class home. There was always food, 2 parents, a roof over my head, education. I had so much luck that when I made a whole bunch of mistakes (to the point that I was hiding in a corner speaking to a heroin addict), I could call up Mum and Dad and move home. This guy had none of that, and worse, people were actively trying to make money off him the entire time. His friends had got him addicted to heroin and then sold it to him, for example. The reason he was sat in the corner for so long was because he'd been late paying his heroin bill so the drug dealer was making him wait until he started to suffer withdrawal before he got some more.

The next day he died of a drug overdose. I stood there in the crowd as they took his body out of his flat. The same friends who'd sold him the drugs were saying things like, "that fucker owed me £20! If you're going to OD you'd at least cash your dole check and pay your mates back first?!"
