The known harmful effects of second-hand smoke have caused an increase in smoking regulations in Florida over the past twenty years. In 1985, the Florida Legislature enacted the Florida Clean Indoor Air Act with the purpose of expressly preempting indoor smoking regulations promulgated by Florida municipalities to the State. In recent years, the Act’s preemption clause has caused confusion as to whether the State intended to preempt only indoor smoking or both indoor and outdoor smoking regulations. This Article explores the legislative history, recent caselaw, and attorney general opinions discussing the Florida Clean Indoor Air Act’s breadth of preemption in an effort to resolve the confusion.
