In honor of 4:20 yesterday, John Mayer took to his Twitter account to announce that he's quitting smoking weed.
Mayer wrote: "I don't smoke pot anymore. I just pay a dude 50 bucks to come over, press lightly on my chest and tell me all my ideas are awesome.
"Any time I feel like smoking pot I just book myself a life insurance exam," he added.
Mayer is infamous for carrying around a marijuana vaporizer and even doing interviews while smoking. He smoked throughout his entire Rolling Stone interview back in 2006.
Mayer's ex girlfriend Jennifer Aniston has also confessed in the past that she "enjoys it once in a while." In fact, while she was still married to Brad, cannabisculture.com named them their favorite "stoner pair."
But one celebrity who recently spoke against marijuana was Britney Spears. Spears stormed off stage during a concert in Canada because the stage was too smoky.
Shocked concertgoers were told the show would not continue if people continued to smoke cigarettes and marijuana in the arena as it was "unsafe" for Britney and her performers.
After Britney returned to the stage, she told the audience: "Thanks Vancouver. You were wonderful. Drive safe. Don't smoke weed!"
May not be a bad idea for him to begin smoking some hookah tobacco instead...
