Singer George Michael has checked into a rehab in Switzerland, with some media outlets reporting that he was smoking 25 joints each day.
The British singer has sold more than 100 million records, including his hit debut, 'Faith.'
Last March the 51-year-old said that he had not used marijuana in over a year and a half, according to an article in the Washington Post.
“I decided to change my life and I haven't touched it,” he said at the time.
In 2010, George Michael spent eight weeks in prison after crashing his car into a shop in London while under the influence of drugs.
