Sir Paul McCartney, member of some band you may have heard of, has turned away from weed for good.

The legendary rock star, who famously smoked pot for much of his five-decade career, told The Daily Mirror that he's given up marijuana to set a good example for his children and grandchildren.

"It's now a parent thing," he explained. "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."

It was the king of folk Bob Dylan who turned Macca on to marijuana in 1964, which he says got him "thinking for the first time, really thinking."

Over the years, McCartney has had his share of run-ins with the law due to his illegal smoking habit. In 1980, he was thrown in jail for 10 nights after trying to enter Japan with a large quantity of weed.

But now at age 72, McCartney is more interested in hitting the gym than he is in hitting the bong.

The former Beatle is focused on eating healthy, staying in shape and impressing bros with his headstand abilities: "But what’s cool about it is that I’ll be in the gym with all these guys doing really big weights, whilst I’m there doing not big weights, and afterwards, when I’ve done my headstand for about five minutes, these big guys will come up to me and say, ‘That was pretty impressive, man!”

My, how things have certainly changed for the rock legend. And Paul, if you're looking for a "nice margarita" recipe, we've got you covered.
