Celebrity Rehab with Dr. Drew, later called simply Rehab with Dr. Drew, is a reality television show that aired on the cable network VH1 in which many of the episodes chronicle a group of well-known people as they are 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.

Sierra, Binzer, and Carey agreed to enter a transitional sober living home in the season finale. All three, as well as Laurer and Foxworth, would eventually relapse; some re-entered treatment. VH1 aired a reunion special detailing the patients' lives since filming. Although Conaway was able to maintain sobriety from alcohol and cocaine, he continued to abuse analgesics for his back pain, and would re-enter treatment in the show's second season. Binzer also appeared in several episodes of the second season for his relapses, as well as the Sober House spin-off series. Laurer was hospitalized in December 2008 and was reportedly going back to rehab. She later was found dead in her house on April 20, 2016.  Nielsen and Rodriguez have reportedly maintained their sobriety. Pinsky has said on numerous occasions that Nielsen has quit drinking and also gave up smoking. Nielsen has also appeared on his radio shows to talk about her sobriety. In 2009, she appeared as a panel speaker to another group at the Pasadena Recovery Center, in which she anticipated the upcoming two-year mark of her sobriety that July, as seen in a third-season episode of the series, which aired in February 2010. Sierra has tested "clean and sober" for a year and a half following a court-ordered year of treatment at the Pasadena Recovery Center, She also appeared with Nielsen in the aforementioned third-season episode, marking her 18 months of sobriety.  The status of Baldwin's sobriety is unknown. As of May 2009, Foxworth is reportedly sober and gave birth to a son. Carey relapsed and returned to porn, starring in and directing a parody film called Celebrity Pornhab with Dr. Screw, a decision which Pinsky said saddened him. Regarding her sobriety, Pinsky commented in a January 2010 TV Guide story, "She puts together, like, six weeks at a time of sobriety, then drifts away. We're trying to get her to stay with it once and for all."
