Los Angeles: Keith Richards claims that he does not regret using drugs.
The 69-year-old Rolling Stones star, who delved into his excessive drug use in his book `Life`, said the opiate was part of his work ethic and helped him create his smash hits, reported Radar online.
"It was either stay up or crash out or wake up. It was always to do something. Also, I`ve got to confess, I was very interested in what I could take and what I could do.
"I looked upon the body as a laboratory ? I used to throw in this chemical and then that one to see what would happen; I was intrigued by that. What one would work against another; I`ve got a bit of an alchemist in me that way. But all experiments must come to an end," he said.
Richards does not believe that any damage was done by his drug use, and that it only enabled him to work harder.
"If I stayed up I got a few more songs out of it. It`s like Churchill said about alcohol, `Believe me ? I`ve taken a lot more out of alcohol than its ever taken out of me!` And I kind of feel the same way about the dope and stuff. I`ve got something out of it. Might`ve pissed off a lot of people!," he added.
