Beatrice McCartney: Paul MacCartney Quits Smoking Cannabis for Daughter

Sir Paul McCartney, a former Beatle, has quit smoking cannabis for the sake of his 8-year-old daughter, Beatrice.

The 69 year old, who has had several run ins with the law for his marijuana use, told Rolling Stone magazine that he has quit using the drug because of a sense of responsibility. McCartney was once jailed in Japan for marijuana possession.

I did a lot, and it was enough, McCartney said. When you're bringing up a youngster, your sense of responsibility does kick in, if you're lucky, at some point. Enough's enough - you just don't seem to think it's necessary.

Beatrice is McCartney's daughter from his second marriage to Heather Mills.

According to Contact Music, during the split and divorce proceedings, Mills claimed that McCartney smoked marijuana as often as most people drink cups of tea.

It's such a difficult argument... You know the argument that if booze is legal, why not that, and then the argument against it is that we don't need another (legal drug)... I'm not going to be the judge of how to deal with it; somebody else can figure that out, he added.

McCartney was reportedly arrested in 1972 in Scotland and Sweden for possession of cannabis.
