Depending on whom you believe, Scott Weiland’s drug addiction ruined the once-popular rock band Stone Temple Pilots. Weiland was in and out of jail and rehab. Now a member of Velvet Revolver with Slash (ex-Guns’n'Roses) and others, Weiland has been arrested for DUI - but for drugs, not alcohol. To make things worse, Weiland refused to take blood or urine test, and failed the sobriety test.
