Sir Paul McCartney has said "enough's enough" and has finally given up smoking cannabis.
The star has been an unashamed dope smoker since the 1960s, leading to him being arrested on occasion and in 1980 he was deported from Japan.
But now the multimillionaire musician - who turns 70 this summer - said being a parent again played a part in his decision to quit.
Sir Paul'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.
