A British judge told the wayward star his addiction to marijuana put him and the public at risk. The former Wham! singer pleaded guilty last month to driving under the influence and possession of cannabis following a July 4 collision between his Range Rover and a Snappy Snaps store in north London. District Judge John Perkins told the singer he had taken a “dangerous and unpredictable mix” of prescription drugs and marijuana. “It does not appear that you took proper steps to deal with what is clearly an addiction to cannabis,” the judge said. “That’s a mistake which puts you and, on this occasion, the public at risk.” Perkins sentenced Michael to the prison time and a 1,250 pound ($1,930) fine during a hearing at Highbury Corner Magistrates’ Court.
