Sir Paul McCartney has quit smoking marijuana for the sake of his children and grandchildren.
The legendary Beatle said in a recent interview, "I don't do it anymore. Why? The truth is I don't really want to set an example to my kids and grandkids. It's now a parenting thing."
72-year-old McCartney has 5 children -- daughters Stella, Heather, Mary, and Beatrice, a son, James, and eight grandchildren.
He says he relies on other things to help him relax now, explaining, "Instead of smoking a spliff, I'll now have a glass of red wine or a nice margarita."
Back in 1980, McCartney was arrested at an airport for attempting to bring a half-pound of marijuana into Japan, which resulted in a nine-day stint behind bars.
