Smoking bans are public policies, including criminal laws and occupational safety and health regulations, that prohibit tobacco smoking in certain spaces. The United States Congress has not attempted to enact any type of nationwide federal smoking ban in workplaces and public places. Therefore, such policies are entirely a product of state and local laws.
Utah was the first state to enact a comprehensive statewide ban on smoking in public places, with the state Legislature passing the Utah Indoor Clean Air Act in 1994. Similarly, California enacted a statewide smoking ban for restaurants that went into effect in 1995. Throughout the early to mid-2000s, especially between 2004 and 2007, an increasing number of states enacted a statewide smoking ban of some kind.
