I dont know of any casino in Las Vegas that is actively lobbying to try to prohibit smoking in its casino. I also dont know of any shareholders, even if they are from Maine, who are actively pressuring the executives of their companies that own those casinos, to get them to prohibit smoking.The Health nanny's started in Las Vegas a year or so ago, but it soon became history and we never heard anymore about LV going smoke free. Too much money involved.
