If citizens can not have the right to commit suicide, they cannot be allowed to stay in an atmosphere full of smoke because that might cause certain chronic disease leading to their unnatural death. Thus, there should be a complete ban on smoking in all the public places across the country. The recent Supreme Court order banning smoking in public places is not restricted to a few metropolitan towns; it must be enforced in all the villages and cities. The three-page order contains certain statements of facts. ?Fundamental right guaranteed under Article 21, of the Constitution provides that none shall be deprived of his life without due process law. Than why a non-smoker should be afflicted by various diseases including lung cancer or of heart only because he is required to go to public places?? Some time back when the court ruled that suicide was unconstitutional and illegal, it had referred to Article 21, which says that State alone has the right to deprive a citizen of his life, but with due process of law. Thus inhaling of smoke by passive smokers has been equated with commission of suicide, an act prohibited under law. But when a person who makes an unsuccessful attempt to commit is liable to face criminal prosecution which man end in his conviction, a passive smoker, however, is immune from any penal action. If one is made to inhale smoke for no fault of his and also against his wishes, the perpetrator of offence of smoking gets away with a nominal fine for such a grave offence that costs the exchequer Rs. 13,500 crore annually in terms of loss of productivity. According to WHO report, smoking may kill seven million people annually. During the last half century, smoking killed more than 10 million people in the developing countries alone. The court also felt that the persons not indulging in smoking cannot be compelled to or subjected to passive smoking on account of acts of the smokers. The ban on smoking order is judicial intervention, and not an activism.
