Len Goodman spent his weekends smoking "wacky baccy" in the 1960s.
The 73-year-old TV star – who served as the head judge on ‘Strictly Come Dancing’ from 2004 to 2016 – loved smoking marijuana during his rebellious years.
He said: "In the 60s I was a mod. We used to go down to Brighton on our scooters.
"I never got involved in the punch-ups. I stayed well clear.
"We used to camp up on Black Rock camping site and spend the weekend, oh yes, with a bit of wacky baccy."
Len doesn’t believe that his use of marijuana caused him any long-term damage, although he can’t be sure either way.
Speaking on his Amazon radio show, ‘LOVE Len Goodman’, the professional dancer confessed: "It did me no harm – it could have done me some harm – I don’t know."
Despite quitting ‘Strictly Come Dancing’ two years ago, Len has continued to work on ‘Dancing With the Stars’ in the US.
But the veteran star recently hinted he may not return to the programme next year because his contract with ABC is up at the end of 2018.
Len doesn’t want to retire, but he also confessed he could happily spend his days "reading a book and pottering in the garden" instead.
He said: "This may be my last season. It’s the end of my contract and they may not what to have me any more.
"They might have had enough of me. I don’t want to retire totally but I’m quite happy doing nothing – reading a book and pottering in the garden."
