Neil Young has reportedly given up smoking cannabis and drinking alcohol to write his forthcoming memoir, Waging Heavy Peace.

Speaking to the New York Times, Young said, “I did it for 40 years. Now I want to see what it’s like to not do it. It’s just a different perspective.”

Young, aged 66, said he has been sober for about a year.

According to another report on Rolling Stone, Young recalls in the book being arrested for drugs with Eric Clapton and Stephen Stills, and jokes about an incident involving CSN bandmate, David Crosby: “I still remember ‘the mighty Cros’ visiting the ranch in his van. That van was a rolling laboratory that made Jack Casady’s briefcase look like chicken feed. Forget I said that! Was my mike on?”

Waging Heavy Peace is published in the UK on October 4.
