Addendum: I keep hearing that it's not the government's job to protect us from harmful substances. Really? Then what's the point of the FDA?
"The legitimate object of government is to do for a community of people whatever they need to have done, but cannot do at all in their separate and individual capacities. In all that the people can individually do as well for themselves, government ought not to interfere." – Abraham Lncoln
I'd argue that addiction weakens the will sufficiently that individuals lose the ability, partialy or totally, to protect themselves.
Update: Just hours after the county passed the ban, the PA state senate exempted casinos from all smoking bans . What a crock of $#*%! Now the county ban is in jeopardy. Why do casinos deserve preferential treatment over bars and restaurants? Stupid greedy politicians. I guess now there's another reason to sweep more incumbents out .
