Smokers cough frequently because

Question

Quizplus · Accepted Answer

When someone inhales smoke from cigarettes or other tobacco products, the smoke irritates and inflames the lining of the airways. This irritation causes the cilia, tiny hairs that line the airways and normally help clear mucus and debris out of the lungs, to become paralyzed. Without the cilia moving the mucus and debris out of the lungs, they accumulate and can trigger a cough. This persistent cough is often referred to as a "smoker's cough."
