In my opinion,smoking in public places should be prohibited.There are many reasons that support this point of view,but today I want to concentrate on three reasons.
One reason is that is harmful for non-smokers,another reason is that smoking is a cause of pollution,and a reason is that smokers have other ways to receive nicotine.
Firstly,smoking is harmful for non-smokers.Smokers should have the right to smoke,but it's not reasonable if that right is harmful to others.Obviously,if people smoke in public places,non-smokers have no choice but to become secondhand smokers.Don't non-smokers have the right to choose not to be secondhand smokers?
Secondly,smoking is a cause of pollution.There is a lot of research that shows that many kinds of gases that are released by smoking and are harmful for the environment,such as tar and carbon dioxide.Everyone knows that now the environment is getting worse and worse.Do you want smoking to be another source of the problem?
Lastly,smokers have other ways to receive nicotine.Nowadays,we have many ways to receive nicotine,such as nicotine gum and nicotine patches.Smokers can use these products instead of smoking.Do you really want people to smoke in public places instead of using these new products?
In conclusion,I want to say that there are no reasons left to permit smoking in public places,and I also think that maybe this is the time for people to quit smoking.Banning smoking is not just for us,but for this world and for everyone who has to live in this world after us.
