I have always hated it, the smell of cigarettes or cigars, they stink and are disgusting!
That feeling could be due to the fact that smoke makes me feel so ill and always has done - my eyes swell and itch, I sneeze and can't breath.
My Dad smoked a pipe till I was 10 when he gave up overnight. He was due for a gallstones op and the anaesthetist showed him photos of smokers' versus non smokers' lungs. That was it, he stopped, and he had smoked since he was age 8 (!)
My bronchitis improved after he stopped smoking although I did still get it every winter till I was about 18, now I do sometimes but not every year.
What is your smoking history? How do you think it connects to your lung issues?
