Celebrity Rehab with Dr. Drew, later called simply Rehab with Dr. Drew, is a reality television show that aired on the cable network VH1 which chronicles a group of people as they're treated for alcohol and drug addiction by Dr. Drew Pinsky and his staff at the Pasadena Recovery Center in Pasadena, California. The first five seasons of the series, on which Pinsky also serves as executive producer, cast celebrities struggling with addiction, with the first season premiering on January 10, 2008, and the fifth airing in 2011. The sixth season, which filmed in early 2012, featured non-celebrities as treatment subjects, and the series name shortened to Rehab with Dr. Drew. Season 6 premiered on September 16, 2012. In May 2013, Pinsky announced that season six was the final season, explaining that he was tired of the criticism leveled at him after celebrities he treated had relapsed and died.
