what feature of the epithelial lining of the respiratory tract is responsible for the smokers cough?
When tobacco smoke is inhaled into the respiratory system, the cilia begin to beat slowly. With time, the cilia, which act like a filter, disintegrate and eventually die away. This leads to smokers getting what is known as a smoker's cough.
there are at least 400 fires started by careless smokers each year.
the anti smoke law was made to protect non smokers and also to try to help smokers to quit smoking!

If a smoker is trying to expel mucus in the respiratory passages, that is done by coughing. Smokers often cough.
Respiratory Illness
For example, children living with smokers are twice as likely to have respiratory problems as children living with nonsmokers.
The tiny delicate cilia are killed by tobacco smoke; and as a result, smokers have few if any cilia remaining in their lungs. Because of this, and the constant irritation of smoke, smokers are much more susceptible to all sorts of respiratory problems.
