Broadcaster Robert Peston has admitted to smoking "a lot of dope" in his teenage years.
Peston, who joined ITV last year from the BBC, has spoken out for Radio 4 show My Teenage Diary.
And timing is everything - he wanted to wait for his youngest son to turn 18 before speaking of his past, reported The Daily Telegraph,
"I didn't do hard drugs, but there was a lot of dope around," he said.
Peston added: "I'm just saying that it happened, and if I look around the people that I grew up with, I don't think it did any of us any serious harm. It certainly didn't do me any serious harm."
In the 30-minute show, the first episode of series seven, Peston reads from his 1974 diary to show host Rufus Hound.
"We find out about his childhood in bohemian North London, his love for prog rock and loon pants, and the reason for the way he speaks," it says on the Radio 4 website.
It is due to be broadcast on Tuesday May 31 at 6.30pm.
