A map of the USA showing which states have smoking bans, based on the Wikimedia Commons' SVG USA map. States with smoke-free bars are blue, smoke-free restaurants red, and smoke-free workplaces green. States which have smoke-free laws in more than one of these locations use additive coloring. For example, a purple state bans smoking in both bars and restaurants. A state which bans smoking in all three locations is white.
