Sir: I have seen people smoking in public buses and no one objects to it. Perhaps this is because of the fact that most people are unaware that they too would be affected badly if someone sitting close is smoking. Some studies even suggest that second hand smoke could in fact be even more harmful than actually smoking a cigarette yourself. I believe that if awareness about the hazards of passive smoking is created among the general public, a great deal of the government’s work will be done.
