Your reasoning starts a slippery slope in terms of rights and is weak arguement at best. People who go to smokey bars know the negative effects of cigarette smoke. I've never been to a town which has no options for non-smokers, for both consumers and employees. Should we ban driving as well? The rate of pedestrian deaths has been decried in the news[1], and its effects are much more immediate.
Your second comment is odd and the start of another slippery slope. You mention the reason it's done is because of higher healthcare costs, yet you mention a special tax that supposedly recovers these costs. This also doesn't take into account the fact that many people pay higher premiums for health insurance as smokers anyhow. This one points directly to a fast food tax because obesity is quickly becoming a leading cause of death[2].
Once again Franklin rings true here:
"They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."
Also note, I'm not a smoker, but I do believe that our freedoms here are being chipped away. Also apologies to the mods if this all is offtopic but (to tie it all together) the removal of online gambling is just another example of freedoms being eroded for the sake of "morality", greed, or what the state thinks is "good for you".
