On the series premiere of "Celebrity Rehab with Dr. Drew" eight drug addicted celebrities check themselves into rehab under the care of Dr. Drew Pinsky and begin their difficult battle for sobriety.
During the acute management phase of the treatment, the celebrities undergo a medical detox and suffer withdrawals.
Jeff finally returns from the hospital, but while he continues to detox, Drew lectures Jeff's co-dependant girlfriend about how her own bad habits will kill Jeff. Meanwhile, another celebrity joins the group, former Ultimate Fighting Champion, Ricco Rodriguez.
The rehabbers deal with their painful and abusive pasts, as many of them are affected by physical, sexual or mental trauma from a very early age. Dr. Drew explores their various issues, having the group work as a whole to overcome their problems.
Everyone reels after finding out about the inappropriate text messaging between Daniel and Mary, so Dr. Drew is charged with pulling the group back together.
After threatening many times during his stay at rehab to leave, Jeff renews his quest to quit. Everyone is growing so tired of his antics that Dr. Drew must move the attention away from Jeff and refocus each member of the group towards their respective recoveries.
The end of rehab is now VERY near and rehabbers must seriously start making plans for sober living. The group even expresses who they think will and won't make it.
After the Catalina fiasco and food fight, Dr. Drew is fed up. He tells the group that even though they are about to leave rehab, the disease is winning and that if they continue to act this way, he's doubts that any of them will make it.
In the season finale, the sober celebs talk about past relationships and where they hope to be after rehab. After all of their hard work, Dr. Drew is ready to release some of his patients, while others are instructed to continue in a sober living environment paid for by VH1. Will they decide to take the recommendation, or head home and continue with their addictions?
