Dr. Drew is coming under fire now that five cast members of Celebrity Rehab have died. Critics are blasting the doctor, saying rehab doesn't belong on TV and that he's been exploiting the show's "patients." Even singer Richard Marx chimed in, tweeting: "I think Dr. Drew Pinsky should change his name to Kevorkian. Same results."

Dr. Drew did some damage control today (Tuesday), calling in to The View. He said he received messages of support from former participants after the death of Mindy McCready, the latest Celebrity Rehab alum to die in the past two years. "I wish I could be more responsible for them," he said of the show's cast. "I've received yesterday about 10 emails and texts from those that are doing well that are so grateful and wanted to reassure me."

Dr. Drew said he hadn't been McCready's doctor in years, but wished some of the show's participants would have continued treatment with his team. McCready, who died Sunday of an apparent self-inflicted gunshot wound at her Arkansas home, appeared on the third season of the show. 

He said it took convincing to get McCready to go a hospital. He said she eventually went, but left "prematurely" because of the fear of stigmatization and "that's when things really unraveled." Losing custody of her children was "the last straw," he added.
