Consumer use of e-cigarettes is rising despite a lack of rigorous safety testing, manufacturing controls, and a well-understood risk profile. Many states and municipalities have prohibited e-cigarette sale to minors or amended their smoke-free laws to restrict public use. I discuss the public health impact of e-cigarettes and the current lack of Food and Drug Administration regulation, and advocate that states and localities reexamine their smoke-free laws and sale restrictions to appropriately regulate public use and youth access.
