"Everybody knows you can die from huffing at any time but, to be honest, that's part of the excitement, really. I mean, if I do butane gas, I spray it in my mouth. I can feel it freezing my teeth and my throat goes numb. You keep inhaling until you get that cold feeling. It doesn't feel unpleasant, but that's what kills you, because if your throat starts to swell up, you're in real trouble. People say I must have problems at home to be a sniffer, but I don't. I just like to try new things" - Carol-Anne, 18, barmaid, Belfast, 1996.
