Paul McCartney quits smoking pot to be a better parent

People often make resolutions when they become parents, whether it's to quit smoking, quit swearing or pledge to live less recklessly.

Sir Paul McCartney is no exception. The ex-Beatle resolved to quit smoking pot for his eight-year-old daughter Beatrice.

"I smoked my share. When you're bringing up a youngster, your sense of responsibility does kick in, if you're lucky, at some point," he told Rolling Stone magazine, according to news reports. "Enough's enough – you just don't seem to think it's necessary."

Mr. McCartney, 69, told the magazine he used to smoke marijuana "a lot." The Telegraph reports his ex-wife Heather Mills, Beatrice's mother, said he smoked pot as often as most people drink cups of tea while the two were going through their divorce.

Mr. McCartney, who has four other children, reportedly did not explain why he didn't give up marijuana for them.

As The Telegraph points out, Mr. McCartney was once known for experimenting with other drugs, such as heroin, LSD and cocaine.

But then, fatherhood has a tendency to turn around even the most nihilistic of men.

As Pennywise frontman Jim Lindberg noted in the documentary, The Other F Word, about punk rock stars-turned-fathers: "It's tough to be a punk rock hero and to be a good authority figure for your kids."

Do you think people should give up pot when they become parents? Have you given up any habits for the sake of being a better parent?
