other addiction specialists, many take issue with Pinsky's methods. Jeffrey Foote, a clinical psychologist and substance abuse expert, stated, "The velvet-glove confrontational stuff Pinsky does is what works for TV, but it's not what works for patients." The web site for Foote's Center for Motivation and Change uses a clip from Celebrity Rehab to demonstrate poor techniques. Foote added, "The dramatic confrontations seen on the show are actually more likely to drive less-severe substance abusers, who are by far the majority, away from seeking treatment." Critics also maintain that the patients' needs and the show's needs constitute a conflict of interest, with Dr. John J.

Defending the practice of paying addicts to attend rehab, producer John Irwin said, "Whatever it takes to get them through the door so they can start treatment—that's the goal."

Despite the involvement of former Alice in Chains bassist Mike Starr as well as an appearance by Nancy McCallum, mother of the original AIC singer Layne Staley, who died of an overdose in 2002, the remaining original members of AIC, guitarist Jerry Cantrell and drummer Sean Kinney, have criticized the show, calling it "disgusting". Kinney said of the program, "It exploits people at their
