How does cigarette smoking result in lung cancer and emphysema?

 

Answer:

Chemical carcinogens present in tobacco smoke are the major cause of lung cancer.

The cigarette smoke irritates the air passages of the lungs causing them to produce mucus which causes cough resulting in enlarging air spaces/ reduce surface area/lose their elasticity (any point can be mentioned) thus difficulty in breathing causing emphysema.
