In my opinion, smoking should be banned, as we all know because of smoking everyday people die, on the packets of cigarette its written that it is dangerous to health and causes cancer then also many people smoke everyday, and the people around the people who smoke are also affected and they don't deserve cancer, as they don't have any habits like smoking which causes cancer.
In my opinion the factories making cigarettes should be first banned, as the people who smoke are blind (yes fully blind) as they cannot see that it is clearly written on the pack "CIGARETTE SMOKING IS INJURIOUS TO HEALTH. TOBACCO IS INJURIOUS TO HEALTH. SMOKING KILLS and TOBACCO CAUSES MOUTH CANCER".
Still they smoke, we cannot stop people from smoking cigarettes, but if the factories are closed then how would anybody smoke and as a result of this there would be less number of cases of mouth cancer and cancer (lungs) caused by smoking. So as a conclusion smoking should be banned.
