Smoking is a Personal Choice?

I can understand how secondhand smoke can be considered annoying, but is it really dangerous?
Yes. Secondhand smoke harms the health of those exposed to it. Secondhand smoke has been proven to cause lung cancer and heart disease, and has been linked to asthma and respiratory problems. Secondhand smoke has 4,000 chemicals, more than 50 of which are carcinogens.

What's wrong with smoking sections? Isn't that a good way to make everybody happy?
No. Smoking sections are misnomers. Smoke travels; it knows no boundaries. Having smoking sections is like have peeing and non-peeing sections in a swimming pool - it doesn't work. Like that yellow substance in the water, smoke circulates, and everybody is exposed to it.

Smoking is legal. Why don't you believe that smokers can smoke where they please?
People do not have the right to harm other people's health. Everyone has the right to breathe clean air.

What's next? Will people want to ban beer and fried foods?
Drinking beer and eating fatty foods are not comparable to smoking cigarettes. Drinking beer or eating fatty foods won't harm those around you; smoking will.
