The Artist: Cee-Lo
When He Quit Smoking: Sometime in the 1990s
Why He Did It: At the height of the success of Goodie Mob, the rapper/singer suffered from a bad anxiety attack one day while smoking weed and decided to give it up for good. "I never got comfortable with it again," he said in November 2010 before talking about a song called "Marijuana" with Slim Thug a few years ago. "When that song came out, I was like, 'I've got a song with Slim Thug...?' I don't even understand what I'm saying."
