I really have NO TOLERANCE for smokers. Even if they are outside it still stinks. The unfortunate part is that it is an addiction like drugs.Plus they REALLY got to want to stop in order to get through the quitting process. They have to be committed 100% not for the sake of others like a spouse or child that has CF but for the sake of themselves they have to want to stop and if THEY want to then they will. I just hate the habit. Even when I am outside lets say eating lunch or dinner at a restaurant and the table next to me is smoking it is just so INTOLERABLE for a non smoker let alone someone with compromised lungs. Smokers just do not get how insidious it is to non smokers... Ugh, I can go on and on! Sorry I have no advice for you cause I truly do not know what I would do if my hubby smoked, it just would be unacceptable for me. Good luck hard thing to handle......<br>
