Firstly, cigarette smoke is very harmful to non-smokers. For years people have been smoking in public thinking its my body, I can do whatever I want to it but in fact smoking not only harms the smoker, but also those around him or her. It causes more damage to their lungs from breathing it. So, people should not be allowed to smoke around other people in public.
Secondly, smoking is a cause of pollution. There is a lot of research that shows that many kinds of gases that is released by smoking and is harmful for the environment, such as carbon dioxide. Polluting the environment affect seriously human beings health. So, smoking should be banned in public.
Thirdly, smoking in front of young people is a bad influence on them. Young people tend to copy what they observe and are the influenced by the normality of smoking around them. If anyone smoking in front of a child, the child may be think it that smoking is a good thing but it is not. The more young people are exposed to smoking the better the chance of them becoming smokers themselves. More importantly, young people can be encouraged to smoke and use other addictive drugs, which is very dangerous. Thus, smoking in public places should be prohibited immediately.
In conclusion, from three reasons mentioned above: Cigarette smoke is very harmful to non-smokers, smoking is a cause of pollution, Smoking in front of young people is a bad influence on them, I do hope that I would never again like to see people smoking in public,
