How to clear your lungs after quitting smoking
Drink lots of fluids, especially water.
Drinking water will help your body to combat the congestion by thinning the mucus in your lungs and make it easier to cough up the mucus. It will also keep your body hydrated.

OUT: Tobacco smoke slows the movement of the tiny hairs (known as cilia) that line our lungs and help to remove mucus. When you stop smoking, these hairs become more active and start to clear away the mucus built up in your lungs.
