Smoking does not permanently leave anything in your lungs. The lungs constantly self clean and I believe after 10 years, all damage from any amount of smoking is removed.
Still, rather not have all that sitting there for 10 years. The liver recovers from a few pints a lot quicker I believe, and even in the less favourable case of a fatty liver, a matter of weeks of abstienence rather than years. Disease of either, is probably a more dangerous situation.

The scarring from all the heavy coughing etc?
