It’s not uncommon to have increased coughing after smoking cessation.
It is because years of tar build-up is loosening and must be expelled from the lungs. Cigarette smoking
destroys tiny hair-like projections lining the respiratory tract called cilia. When you quit smoking
, the cilia need to repair and regenerate themselves. Coughing is often due to the reemerging cilia. But you should see a doc.
