From the ASAM blog:
…is there any evidence that the general public requires less treatment than do healthcare professionals and pilots? I would further ask, given the excellent outcomes generally obtained by PHPs and pilot recovery programs, why there have been no studies in which members of the lay public go through identical programs to determine what their long term outcome would be. Indeed, what happens when a non-healthcare professional or non-pilot goes through 90 days of rehab, and is then followed regularly by an addiction specialist physician while simultaneously attending twelve-step or similar self-help groups and being subject to random urine drug testing, all as the FAA requires of pilots requesting a special issuance medical, and as state medical boards generally require of physicians wanting to return to practice? Would they too have an 80-90% recovery rate?
