In the United States, Congress has not attempted to enact any nationwide federal smoking ban. Therefore, smoking bans in the United States are entirely a product of state and local criminal and occupational safety and health laws. As a result, the existence and aggressiveness of smoking bans varies widely throughout the United States, ranging from total bans (even outdoors), to no regulation of smoking at all. Jurisdictions in the greater South tend to have the least restrictive smoking bans or no statewide bans at all. Of the 60 most populated cities in the United States, all but 17 ban smoking in all bars and restaurants.
