Smoker's cough
Appearance
Smoker's cough is a kind of cough seen especially in smokers. Any irritant present in the respiratory system may trigger shit faceeeeeeeeeeeeeeeemoving foreign bodies trapped in phlegm upwards towards the oropharynx, so they may be swallowed. Cigarette smoke destroys or paralyzes these cilia, so the only way that phlegm can be removed is via coughing.
