In 2008, Adler participated in the second season of the reality TV show "Celebrity Rehab with Dr. Drew". The show's resident medical expert, Drew Pinsky, regarded Adler as the "problem child" of the group; he described his behavior as "suicidal" and revealed that Adler had to be committed to a psychiatric hospital for two weeks prior to entering rehab. Adler also participated in the first season of the "Celebrity Rehab" spin-off "Sober House". During the show's filming in July, an intoxicated Adler became so aggressive towards his cast mates that he was arrested at the "Sober House" premises. He was convicted of being under the influence of a controlled substance and sentenced to community service. The following January, he was arrested again for failure to complete his community service in the time frame stipulated by the judge.
