Rocker John Mayer is putting down the bottle and picking up the bong. The 'Love on the Weekend' singer says he's already noticed an improvement in his enjoyment of life after swapping out alcohol for marijuana.

"I put it [marijuana] where drinking used to go, and the quality of life has gone up considerably," he told Rolling Stone. "Drinking is a fucking con. How much is enough? Every time I drank, I was looking for some sort of regulated amount. It always feels wrong for me. I always feel like I went overboard. 'I said two, now it's three, now we're at four?' I never had a serious issue with it, but I remember looking around going, 'This feels rigged. I'm taking a break.' There's never an amount that felt like I was succeeding at life. It always felt wrong."

But the decision wasn't easy since he used to abstain from mind-altering substance.

"I was always the guy saying that I didn't like altered states," he added. "Once you know who you are, then it becomes OK. I'm much more open-minded to small changes in consciousness. I remember every trip I ever took. I remember every thought I ever had when I laid there."

And you can already see the influence appearing in his musicianship. On top of touring with legendary jam band Dead and Co., Mayer is trying to get Jay Z onboard with a hip hop tribute to Jimi Hendrix and 60s psychedelia.

"I think there's room for psychedelia in hip-hop. I just always thought a Cream-Hendrix rhythm section for hip-hop would be insanely cool," he said.

Your move, Hova.
