Smoking should be banned to reduce pollution and disease. First of all it will significantly reduce the risk of heart attacks and other diseases, particularly among individuals such as children and non-smokers. Secondly, it will help public places be less toxic and we won't have to deal with pollution. Finally, It could also help some people quit smoking. If people were allowed to smoke in public places they may not be as motivated to stop smoking as they are with not being allowed to smoke in public areas.
