George Michael reveals he quit smoking cannabis more than a year and a half ago.
The 'Faith' hitmaker explained he has "completely stopped" taking the drug, and been clean for more than 18 months.
Asked if he still smokes marijuana, he told The Big Issue magazine: "Not at all. I've completely stopped. I haven't touched it for well over a year and a half now."
The star also revealed how his stay in Pentonville prison in 2010 - following a car crash while high on cannabis and anti-anxiety pill Amitriptyline - was "easier" than he expected because he knew it was "deserved".
He explained: "Jail wasn't great. I just thought, get your head down and get on with it. It turned out to be easier than I was expecting because I knew I deserved to be there ... I was pretty overwhelmed by the love and support [the fans] showed me."
He also opened up about his battle with pneumonia a few years ago, during which he spent weeks in an intensive care unit.
He said: "On a sub-conscious level it was very frightening and I'll probably never feel quite as safe again. But I was just so grateful to come out alive and get back to my home in London."
