Statewide bans on smoking in all general public places
24 states have enacted statewide bans on smoking in all enclosed public places, including bars and restaurants: Arizona, California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Iowa, Maine, Maryland, Massachusetts, Minnesota, Montana, Nebraska, New Jersey, New Mexico, New York, Ohio, Oregon, Rhode Island, Utah, Vermont, Washington, and Wisconsin (effective July 5, 2010).

Statewide bans exempting bars
7 states ban smoking in most enclosed public places, but permit adult venues such as bars (and casinos, if applicable) to allow smoking if they choose: Arkansas, Florida, Louisiana, Nevada, Pennsylvania, North Dakota, and Tennessee. In Florida, Pennsylvania, and Tennessee, state law preempts local governments from enacting stricter smoking bans than the state, though in the other five states, some cities and/or counties have enacted stricter local smoking bans to varying degrees.

Unique statewide smoking bans
6 states have enacted smoking bans in particular places: Georgia bans smoking in restaurants where persons under 18 years of age may enter, but allows most anywhere else either to designate smoking areas indoors or allow smoking freely. Idaho, New Hampshire, North Carolina, South Dakota, and Virginia also have unique statewide smoking bans.
