While VH1’s latest celebreality offering isn’t set to air until January, videos from “Celebrity Rehab” have surfaced online. Whether the celebs involved are simulating drug use or actually using on camera isn’t quite clear, although in the clip with “Taxi” star Jeff Conaway (below), he says, “By the way, this is pablum. I don’t want you to get the wrong idea.” He explains that he snorts it “to go to the bathroom because of all the pills that the doctors put me on.”

“Celebrity Rehab” is scheduled to air on January 10th, with Dr. Drew Pinsky helping nine former stars with their addiction problems. Jeff Conaway, “American Idol” finalist Jessica Sierra, actor Daniel Baldwin, actress Brigitte Nielsen, porn star Mary Carey, Crazy Town’s Seth Binzer and former wrestler Chyna will participate on the series. The question is, can Dr. Drew set these celebs straight?
