The Artist: Mark Wahlberg
When He Quit Smoking: 2011
Why He Did It: First of all, are we stretching the term "rapper" and "artist" here? Yes. Deal with it. Marky Mark used to be a rapper and he also used to smoke weed until his kids convinced him to give it up. "I stopped smoking weed for my kids," he said at the Indie Impact Awards in early '11. And he did so because his daughter once confused the weed smell on his clothes for a skunk. "Sometimes Daddy smells like that," he remember her saying. Good reason.
