It is known to everyone that srnoking is harmful to our health. Research conducted in many countries has indicated that smoking causes lung cancer, heart disease and various respiratory illnesses.
Responding to overwhelming medical evidence of the harnful effects of smoking, many governments have taken actions to reduce tabacco consumption. Some have imposed heavy taxes on tabacco products, others have conducted anti-smoking campaigns.In theatres,cinemas and some public places nonsmoking is often demanded by authorities.
However, none of the governments have even considered prohibiting the sale of tobacco. This is due partly to the political power of the big tobacco companies and partly to the fact that so many people, particularly in influential position in society, are habitual smokers. Tobacco farmers and workers are also strongly opposed to legislation. In fact, smoking is not only a matter of habit but also a matter of profits.
