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.

The scarring from all the heavy coughing etc?
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.
