Great job on quitting the cancer sticks. I would think that it will take a long time for the lungs to recover completetly (if posssible) from the smoking.

It really depends on your age and how long you smoked as far as what you can expect. But just kicking the habit is an admirable accomplishment. I quit chewing tobbaco when I was a teen and it was tough. I grew up in an area where chewing tobbaco was like drinking water. You just did it.

Congrats...
