For many years there has been a problem in our university with the smoking and not-smoking areas. It seems that anybody respect the areas where they shouldn't smoke. So although smokers have the right to smoke and they probably need to do it, it would be better if all the university were smoke free, because passive smokers are damage and might star smoking, and also it can cause many environment problems.
If you are a passive smoker your body is damage in the same way as if you were a smoker. When a person is around people that is smoking, that person is breathing all the smoke they exhale, this is very harmful for the body. All that smoke is a mix of the cigarette's nicotine and the CO2 of the other person. So that means that if you are a passive smoker you are breathing something as harmful as a cigarette.
People usually start smoking when they are teenagers because of the peer pressure. That behavior is very common in that age, but that doesn't just happen when you are a teenager. When you are in a group that have one thing in common, usually in an unconsciously way you try to fit in, it doesn't mean that the person doesn't has a personality, it is just a typical reaction on the human beans. So a smoking environment might make an influence in people and get them to start smoking.
Smoking is a very dirty habit. When you smoke you throw the ashes and the butt away and usually in our university people do it in the floor. If hundreds of people do that many times every day, it is impossible to imagine the quantity of ashes and butts that we have around. It is true that those areas are cleaned everyday, but it is impossible to clean all the ground, so that dirt stays there and contaminates the environment that surround us and the place in which we study. .
Smokers have he right to smoke if they want to and in some cases they really need it. This is something to think about, there are a lot of reasons to make the university a non-smoking area but we have to think also in the smokers.
