Ban smoking in public places

Last Sunday I saw in a newspaper an advertisement about passive smoking or a second-hand smokers. In it, you can see a little girl and this sentence:

“This girl smokes a packet every day. Because every time that someone smokes in front of a cild, she or he is to be forced to smoke. Choose spaces without smoke".

First of all, I think that smoking in public places should be banned, because it is unfair on people who don't want to inhale the smoke of other people.

Secondly, there are some arguments for the ban, for example:
-Passive smoking is dangerous
-A majority of people favour a smoking ban
-A ban would encourage more smokers to give up
-People have a right to protect themselves from smoke inhalation
-Smoking is a habit which is addictive

We all know smoking is not healthy. Unfortunately when smokers are able to smoke in public buildings they can make other people sick.
I think that smoking should be banned in public places especially restaurants. why should nonsmokers have to take in other peoples smoke when they are eating.

Finally, not allowing smoking in public places and office buildings is a very good rule. I believe this for several reasons. Not only will banning smoking improve people’s health, it will also increase worker productivity and reduce conflictivity
