“My mate Karl once told me he’d been looking after this five-year-old boy who – not knowing enough to have an ironic inflection to his words – said, ‘I want something.’ He didn’t know what it was. Not ‘I want sweets’, or ‘a can of Coke’, or ‘to watch the Tweenies’, or whatever it is they’re into now (I like Bagpuss), but ‘I want something.’ All of us, I think, have that feeling. And what heroin does when you first start taking it is tell you what that something is.”

“I've never had a sustained period of medication for mental illness when I've not been on other drugs as well. It's just not something that I particularly feel I need. I know that I have dramatically changing moods, and I know sometimes I feel really depressed, but I think that's just life. I don't think of it as, "Ah, this is mental illness," more as, "Today, life makes me feel very sad." I know I also get unnaturally high levels of energy and quickness of thought, but I'm able to utilize that.”

“I want to change the world, and do something valuable and beautiful. I want people to remember me before I'm dead, and then more afterwards.”

“I've always been a 'your parents have got to come up to the school' type of person. Even now, when I do something wrong - if I say something inappropriate on a live tv show, for example - I half expect to have to deliver a note to Barbara Brand: 'Please come up to Channel 4 head office, Russell's done something despicable.”

“What was so painful about Amy’s death is that I know that there is something I could have done. I could have passed on to her the solution that was freely given to me. Don’t pick up a drink or drug, one day at a time. It sounds so simple; it actually is simple but it isn’t easy; it requires incredible support and fastidious structuring.”

“Even as a junkie I stayed true [to vegetarianism] - 'I shall have heroin, but I shan't have a hamburger.' What a sexy little paradox.”

“Being famous is like a little bit of you is taken away and goes off and lives on its own and does what it wants... I wish it would do more interesting things!”
