On the national level, several laws restricting smoking in public places have been passed. Federal law bans smoking on domestic airline flights, nearly all flights between the United States and foreign destinations, interstate buses, and most trains. Smoking is also banned in most federally owned buildings. The Pro-Children Act of 1994 prohibits smoking in facilities that routinely provide federally funded services to children.
Many state and local governments have passed laws prohibiting smoking in public facilities, such as schools, hospitals, airports, bus terminals, parks, and beaches, as well as private workplaces, including restaurants and bars. Some states have passed laws regulating smoking in multiunit housing and cars. More than half of the states have enacted statewide bans on workplace smoking.
To highlight the health risks from secondhand smoke, the National Cancer Institute, a component of the National Institutes of Health, holds meetings and conferences in states, counties, cities, or towns that are smoke free, unless specific circumstances justify an exception to this policy. More information is available online.
The U.S. Department of Health and Human Services Healthy People 2020, a comprehensive, nationwide health promotion and disease prevention agenda, includes the goal of reducing illness, disability, and death related to tobacco use and secondhand smoke exposure. Currently, most Americans are exposed to secondhand smoke, and children are at greatest risk. For 2020, the goal is to reduce the proportion of people exposed to secondhand smoke by 10 percent. To assist with achieving this goal, Healthy People 2020 includes ideas for community interventions, such as encouraging the introduction of smoke-free policies in workplaces and other public areas.
More information about this program is available on the Healthy People 2020 website.
Internationally, a growing number of nations, including France, Ireland, New Zealand, Norway, and Uruguay, require all workplaces, including bars and restaurants, to be smoke free.
