As a smoker that's making a feeble attempt at trying to quit, I could understand this. It's a gross habit in really every way that it can be, it's totally within reason for a town or city to say they don't want it both metaphorically and literally littering their public works.
Yes, I believe that there should be a ban on smoking in public places. Have smoking and non-smoking area are not sufficient. Smoke does not magically stay in the smoking area, it migrates any where it so chooses. It is a health hazard to those that choose not smoke and it seeps into clothing and hair. If a smoking area is warranted then it should be enclosed so that the smoke does not move around others.
Smoking is harmful to people's health and it should be banned in public places. The government should make stricter laws limiting the use of cigarettes in order to improve public health. It is not fair for smokers to force non-smokers to breathe in their second hand smoke. Smoking should only be done in private.
Smoking should be banned in all public places. People should not have to suffer from second hand smoke or deal with that nasty smell. If you want to smoke, then you should take your bad habit away from public places and do it at home or at other private areas.
Smoking should be banned in public places mostly because the second hand smoke is terrible for people to inhale and anyone who is not smoking is not going to like walking on a sidewalk and suddenly have a huge smoke cloud around them. It is not fair to subject the people who do not want to smoke to their bad habits.
When people breathe in second hand smoke, their health is being put in danger. When smoking is made illegal in public, that will be to the benefit of the public good, because fewer and fewer people are being put in danger by the foolish actions of selfish people. Everyone will benefit from this.
Smoking negatively effects the health and comfort of more than just the person that is smoking. While I believe that people should have the freedom to do with their bodies as they choose, smoking effects more than just the smoker. Smoke can be very irritating to those in the near vicinity. It smells awful and the smoke can make it difficult to breathe. It causes others to cough. The effects of second-hand smoke have been proven in many studies and the consequences of continued exposure to second-hand smoke are clear and deadly. There are also those that suffer from conditions like asthma that make constantly breathing smoke a real health concern.
I think all out bans can be somewhat dangerous, because when you consider some public places, public smoking is still common and actually accepted. Bars have experienced problems in some states that have eliminated all smoking within properties. Ultimately, I think decisions like these should be left up to business owners, not governments. Public places like parks, which are open, should not be a problem for non-smokers and smokers a-like to utilize without being bothered by the other. Therefore, in that setting, I feel smoking should be fine.
