It may be the strangest chemical ever to alter Rolling Stones guitarist Keith Richard's state of mind — a mix of cocaine and his father's ashes.

"The strangest thing I've tried to snort? My father — I snorted my father," Richards said in an interview with British music magazine NME.

Richards' father, Bert, died in 2002 at age 84, but apparently was a sanguine sort of fellow.

"He was cremated and I couldn't resist grinding him up with a little bit of blow. My dad wouldn't have cared," Richards said. "… It went down pretty well, and I'm still alive."

Jane Rose, Richards' manager, later claimed the comments had been made "in jest" and that she couldn't believe people had taken them seriously.

In the interview, Richards, now 63 and legendary for abusing various illegal substances, also credited his long survival to dumb luck.

"I was No. 1 on the 'who's likely to die' list for 10 years. I mean, I was really disappointed when I fell off the list," Richards said, advising young musicians against emulating his lifestyle.

"I've no pretensions about immortality," he added. "I'm the same as everyone … just kind of lucky."

Richards, still touring with the Stones in their extended Bigger Bang tour, is to play Johnny Depp's father in the next Pirates of the Caribbean film.
