A member asked:

How long does it take for the lungs to regain normal functioning and cleanse itself after quitting 8 pack-years of smoking?

A doctor has provided 1 answer

weeks: Bronchial inflammation and increased mucus production should return to normal in 1-2 mo. Bronchospasm from smoke irritation should also be much better after a couple of weeks. Frequently nasal congestion and post nasal drainage clear in 2-3 weeks.
