sorry to hear that, when the subject came up my doctor had no problem with me using marijuana provided I don't smoke it, is your doctor a resident or attending? if they are a resident I'm sure you know in a few years you get a new doctor, personally I went through 3 residents before I was assigned to an attending. personally nothing causes hunger quite like marijuana munchies, and i've been on 2 different appetite inducing medications for about 7 years. if it's not causing a negative effect on your lung function I wouldn't stress it, since it obviously works for you. its also disappointing that your doctors are treating you differently since I'm guessing its making you want to not tell them everything, maybe you can mention it next clinic appointment, you told them something in the interest of complete disclosure (I'm guessing) and they should respect the trust you put in them with that information, and not to use it against you (or allow it to effect how they treat you)
