Smoking is the most dangerous of all habits. I consider it a bad habit. It has a damaging effect on human health and life. It breeds many fatal diseases . It causes cancer , bronchitis , tuberculosis , heart – attack and many health hazards . Smoking prevents free flow of blood and supply of oxygen in the body . This leads to serious heart problems . A chain smoker cannot enjoy sound health . A smoker also causes harm to a non – smoker . Besides , Smoking pollutes the air and leads to environmental disaster . Still, the worst sufferer is the man who smokes . He cannot but suffer in the long run . However, there is no smoker in our family . My father who used to smoke occasionally has got rid of it and now the family is totally smoke free . Recently smoking in the public places has been banned by the government . As smoking is a slow poison, banning smoke in public is a commendable initiative. We should come forward to maintain and materialise this law by people.
