Gary Busey Admits He's Done Coke Off A Canine Hooker's BackFans of Celebrity Rehab's first season will recall it featured several breakout recoveries, including those of failed hip-hop superduo Vikki & Kenickie, as well as the addictionless Joanie "Chyna" Laurer, who right up until CR commencement exercises refused to reveal the enigmatic circumstances that led her into the program. Tomorrow night, the second season premieres on VH1, but a preview already posted online suggests that Gary Busey—who's made it clear his involvement is strictly as mystical, recovering-coke-fiend mahatma to the other patients—could wind up contributing more story-editor-nip drama to the proceedings than spiritual guidance.In the following video, the actor describes his ongoing struggles with Bolivian marching powder, reaching near Marcia Brady-levels of desperation and interspecies-sexual-favor-trading in order to get his hands on the stimulant. When time comes for check-in, rehab tech Shelly finds an agitated and uncooperative Busey unwilling to part with essentials like mouthwash, mobile phones, and large bags of weed, while minutes later a concerned Dr. Drew listens compassionately as a broken Busey relays the time he snorted blow off his own dog's back. Helluvuh drug.
