Detailed explanation-1: -The chemicals you inhale when you smoke can cause inflammation and changes in your airways. Smoking damages the small hairs (cilia) that line your airways and usually help to keep them clear. Your airways also produce more mucus than normal. Coughing is your body’s natural way to overcome these changes.
Detailed explanation-2: -Smoking causes inflammation in the small airways and tissues of your lungs, causing your chest to feel tight. It also makes you feel short of breath and wheezy. This inflammation builds up the more you smoke and can turn to scar tissue that provokes physical changes in your airways and lungs.
Detailed explanation-3: -Over time, smoker’s cough can lead to hoarseness and chest pain. It can also be among the signs and symptoms of lung cancer. One study of young military recruits found that 40% of the 525 subjects who smoked regularly experienced a chronic cough with sputum production; only 12% of the 408 non-smoking participants did.
