smoking is harmful for your health. Many smokers die because of cigarettes. Tobacco is a drug for many people, they can't stop it. Smoking must be forbidden in public places. Smoking is not pleasant for nonsmokers.I don't smoke (of course). And my family doesn't have smokers. So I hate smoking. Smoking is not good for our bodies' health. So I won't smoke in my life.Actually the tobaco smoke contain three principal dangerous chemicals; i.e. tar,nicotine & CO. Tar badly affects our lungs, nicotine affects our lungs, nerves & cardiovascular system. All these problems may lead to cancer. Smokers by kissing cigarettes may get mental satisfaction, they may get mental pleasure, but they simply burn their life span.
In my opinion, the smoking ban in public places is a very good idea. Why? when I go to restaurants, my clothes smell of cigarettes and it is very unpleasant. Secondly, smoking is dangerous for smokers' health and non-smokers' health. Thirdly, the smoking ban is excellent because a lot of people die of lung cancer. In conclusion, I say the smoking ben will not be for pubs' landlords because customers will always go to pubs to have fun.

Finally,

Although smoking in public places is very common there are some people who think that public smoking in certain places should be banned by law and I support this idea. In my opinion it should be banned particularly in places where people eat.
