KEITH Richards wants to "road-test" any new drugs that are invented.
The Rolling Stones rocker - who admits to have using numerous illegal substances over the years, including heroin and cocaine - doesn't take drugs anymore, but he would if something new came on the market.
He said: "I've given up everything now - which is a trip in itself.
"I'm just waiting for them to invent something more interesting, ha ha. I'm all ready to road-test it, when they do."
Keith gave up heroin in 1978, and was forced to quit cocaine in 2006 after accidentally falling from a coconut tree and undergoing brain surgery.
He said: "That was cocaine I had to give up for that. You're like, 'I've got the message, oh Lord.'"
Because of his wild past, the 66-year-old musician is convinced he will be going to hell when he dies.
He told The Times newspaper: "Well I'm not putting death on the agenda. I don't want to see my old friend Lucifer just yet. He's the guy I'm gonna see, isn't it? I'm not going to the Other Place, let's face it."
Keith is also proud of the amount of time he has spent on the Most Likely To Die list over the years.
He said: "I used to read it, check I was still on there. I was on it longer than anyone else. Badge of honour!"
The rocker also admits his drug habit was so extreme, he had a custom made hat to hide his supplies, and a side-panel in his car filled with illegal substances.
He added: "There was a flap at the side in which I'd stowed hash, Tuinals and coke.
"I'd spent hours packing the side-panel of the car with coke, grass, peyote and mescaline."
