Can't undo, but good: repair in 1-9 months. Fortunately, pulse and blood pressure respond within a few hours, oxygen levels in less than a day, and recovery starts in a few days. Nicotine causes damage to the cilia and lining of the bronchial tubes and the amount of damage is related to how long and how much one has smokes, ie 3 packs in 6 months vs 3 ppday.

Female, 31 yrs old. I smoked a pack of cigarettes a day for 1 year. I have quit and plan on never smoking again. Can my risk for lung cancer eventually become that of a non-smoker? If so, how long will it take?

Hello. I have a lump that's been in my mouth under my teeth in the soft gum part. Some days its inflated, other days, its "deflated" with a rough patch there. I'm a smoker and I smoke on average one pack per day but I've only been smoking for three years.

I quit smoking 6 years ago. 2 months ago I relapsed, probably smoked about 10 packs during that time. My question is did I totally negate the healing my body and lungs have made during the 6 years of not smoking? Thank you?
