It's now a parent thing: Paul McCartney on quitting marijuana

The Beatles star Paul McCartney has revealed that he has given up marijuana.

"I don't do it anymore," he was quoted as saying on mirror.co.uk.

"Why? The truth is I don't really want to set an example to my kids and grandkids. It's now a parent thing."

McCartney, 72, admitted that he was afforded his first taste of the drug by singer-songwriter Bob Dylan in 1964.

"Back then I was just some guy around London having a ball, and the kids were little so I'd just try and keep it out of their faces. Instead of smoking a spliff I'll now have a glass of red wine or a nice margarita. The last time I smoked was a long time ago," he added.
