My dad, age 44, has Sarcoidosis. He's been smoking ever since I can remember, at least 20 years. I know smoking is usually bad for your health even if you don't have Sarcoidosis. What I wanted to get some advice on, is how might the smoking be effecting his Sarcoidosis. Since it's an immune system problem, wouldn't the smoking make it even worse? By the way he is doing fine with his Sarcoidosis. The only problems is he's got some parts on the back of his neck where it's very obvious his immune system is overreacting. Also on his inner thighs, he's had 2 "tumor" like things removed. I'm told they were from his immune system taking all the stuff your body throws away and storing it there. I don't know if his casual smoking makes it worse. He tries to hide the smoking from me, but I know he does it about 4-5 times a week not, when before I started complaining it was 1-2x a day.
