My wife is being evaluated for liver transplant right now because she has severe Hepatopulmonary Syndrome. My son would like to be a living donor but I'm not sure whether he would even be considered. He was addicted to Fentanyl for a couple of years and for 8 years before that he used drugs and alcohol too much. He has been on Methadone treatment for 3 years now and I think it is as bad as any street drug to get off of. The other issue he had was that he had 2 collapsed lungs as a teenager which were both surgically repaired (they were not caused by any trauma, he was one of those tall thin teenaged boys that this can happen to, and they were surgically repaired by "gluing' them to his chest cavity to allow them to heal) Even with this, he still smokes a pack a day. I really think he wants to do this for his mum to redeem himself for all the crap he put us through for 14 years. They are both hoping that this will be the solution for her, I'm worried they are going to get their hopes up too high. Anyone have any experience regarding this? Would an active Methadone user be considered for living donor status or would he have to be off of it for a certain amount of time before he's considered? Any input would be really appreciated.
