Sir Paul McCartney has revealed he has finally given up smoking cannabis after deciding "enough's enough".

The star has been an unashamed dope smoker since the 1960s and has been arrested on occasion as well as famously being deported from Japan in 1980.

But now the multimillionaire musician - who turns 70 this summer - said that being a parent again had played its part in his decision to quit.

Macca's regular cannabis consumption was flagged up by second wife Heather Mills during their divorce battle. The couple have an eight-year-old daughter Beatrice from their relationship.

In a new interview with Rolling Stone magazine, he said of his dope use: "I did a lot, and it was enough.

"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 added: "Enough's enough - you just don't seem to think it's necessary."

The Beatles were introduced to cannabis by Bob Dylan in August 1964.
