Many states have passed statewide bans on smoking in enclosed public places, including restaurants and bars. Other states have enacted statewide smoking bans that include exceptions for certain businesses and workplaces—such as cigar bars, tobacco shops, and private clubs.

Some cities and towns have enacted ordinances (laws) that restrict smoking in restaurants and bars—and some cities and towns extend public smoking bans outdoors to sidewalks, apartment complexes, and other public spaces where nonsmokers may congregate, for example.

Violations of these smoking bans may be prosecuted as misdemeanor criminal offenses and include hundreds of dollars of potential fines.

In Idaho, the statewide smoking regulation is governed by the Idaho Clean Indoor Air Act, which prohibits smoking in most enclosed public places, including schools, public transportation, and areas of employment. However, there are exceptions to this rule, allowing smoking in designated smoking areas, bars, small workplaces with fewer than five employees, and other specified locations. Local governments in Idaho have the authority to enact more stringent smoking ordinances. For instance, some cities may extend smoking bans to outdoor public spaces or implement stricter regulations for restaurants and bars. Violations of the Idaho Clean Indoor Air Act and local smoking ordinances can result in fines and are typically treated as misdemeanors. It's important for individuals and businesses to be aware of both state and local regulations regarding smoking to ensure compliance.
