Montana Clean Indoor Air Act
The Montana legislature passed the Clean Indoor Air Act (CIAA), one of the most important public health policies in state history, in 2005.
The law requires all enclosed public places and workplaces, including work vehicles, or vehicles that serve as a place of work, and vehicles accessible to the public, such as taxis and buses to be smokefree; and it requires businesses to prominently place smokefree signs on all public entrances. The Montana Department of Public Health and Human Services has adopted these rules.
The health benefits of the Clean Indoor Air Act are three-fold:
- Patrons and workers alike are protected from the deadly health effects of secondhand smoke exposure.
- More people who smoke will try to quit.
- Fewer Montana youth will begin smoking.
