Kiefer Sutherland says his time in jail made him realise he could quit smoking.
The 24 star served 48 days behind bars for drink-driving last year.
And Kiefer, 41, says he didn't light up once during his stay.
'There's no smoking,’ he tells Men’s Vogue. 'The lights never go out, 24/7. You can't cover anything.
'You can't even put your head under a blanket. All the cells have cameras in them.
'My drinking was not a daily thing, so it wasn't an issue. And, oddly enough, neither was the smoking.
'I was very glad to know that I could quit.'
