After analyzing the area of smoking is harmful to hygiene and smoking in public portrays a bad example. As has been proven, smoking should not be allowed in public area, because besides the two examples above, I think smoking should be banned in public places. That is because non-smokers should not be forced to secondhand smoke against their will. Even though it is an obvious etiquette not to smoke when surrounded by many people, a large number of smokers do not seem to care so much about it. For example, it is not that hard to find a person smoking at a bus stop even if there are little girls around him or her. There should be rules restricting people who have little regard for the well-being of others. Another reason why smoking should be banned in public places is because of the garbage problem. Not many smokers throw away their cigarette butts into the trash cans. Most of them just toss it on the streets. The streets will be much cleaner if smoking is banned. Therefore smoking should not be allowed in public area
