"Accepting that there may exist certain kinds of expressive conduct for which actual speech could not provide an adequate substitute, such as, erotic dancing, the Supreme Court has made clear that regulations limiting the full expressive impact of such conduct can nevertheless comport with the First Amendment. See Erie, 529 U.S. at 301, 120 S.Ct. 1382 (plurality opinion) (although prohibiting full nudity, a law permitting dancers wearing "pasties" and "G-strings" leaves open ample alternative channels of expressing the message of erotic dancing). Whether or not the use of a fake or prop cigarette can have precisely the same dramatic impact or convey the same degree of realism as an actual, burning, smoke-producing cigarette, it, like the theatrical use of substitutes for virtually every other type of dangerous or illegal conduct, is capable of amply communicating to an audience an intended message. Especially in the context of a theatrical performance, where the message is typically conveyed by imitation rather than by scientific demonstration, some resultant lack of realism cannot be considered fatal to the regulation of conduct. Because it is clear, without further evidentiary support, that the state has a significant interest in protecting the health and welfare of its citizens and that the welfare of those citizens would be more exposed to harm without the smoking ban than with it, the ban is adequately tailored for purposes of the First Amendment to the United States Constitution."
