Should the government ban smoking in public?

In my opinion,the smoking ban in public places is good because nonsmokers shouldn't breathe the smoke of smokers. It's unheathy for nonsmokers and smokers too. For example, at the disco, smokers don't respect nonsmokers and dance in smoke. It's dangereous. For me, it is a good idea to ban smoking in public places because smoking is unhealthy for health. Kids have to be protected from smokers and with a smoking ban, it's an opportunity for smokers to stop smoking....
