George Michael reveals he quit smoking cannabis "over a year-and-a-half" ago.
The ‘Faith’ hitmaker explained he has "completely stopped" taking the drug, and been clean for over 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."
