THE Rolling Stones guitarist Keith Richards insists he always took drugs "responsibly" - evenly spaced throughout the day. Richards, notorious for his legendary substance abuse, is adamant his habits were just part of his daily routine. The only problems he experienced were when the drugs he scored were contaminated, but most of the time his fixes were nothing more than a pleasant meal-time treat. He says, "Actually, I would take drugs quite responsibly. A nice fix at breakfast, one for elevenses and another one at tea time - it was like breaks at the cricket or something. "The times I f**ked up was when I scored from people I didn't know and the stuff was laced with strychnine. I'm lying on the bed and people are going, 'Well, he's still breathing...'"
