The same argument is made and accepted about alcohol: You can drink as much as you want but you cannot put others in danger by drink driving.

You can smoke as much as you want but smoking in public places, especially indoor, is banned not to impose your health choices on others.

This is how liberty works in a free society as mentioned in my previous comment.

Banning smoking altogether, on the other hand, is deciding for you and exactly what the "nanny state" refers to.
