Tobacco contains a deadly poison – nicotine. This poison, when inhaled, injures the heart, lungs, brain and liver. It also effects the digestive system. Even indirect smoking, that is, sitting by the side of a smoker who is emitting smoke, is also injurious to the health of a non-smoker. He should, therefore, avoid sitting close to the smoker. Inspite of so many dangers to health, smoking is on an increase. The younger generation is seen to be falling a prey to this bad habit.
