The Montana Clean Indoor Air Act (CIAA) prohibits smoking, including the use of marijuana and e-cigarettes, in all enclosed public places (Title 50, Chapter 40, Part 1, MCA). It also requires establishments containing an enclosed public place to post a sign in a conspicuous manner at all public entrances stating that smoking is prohibited. In addition, tobacco products of any kind, including e-cigarettes, are not permitted on public school property at any time (§ 20-1-220, MCA). Click here for more information about the state law.

All complaints concerning violations of the CIAA are a matter of public record. For complaints to be considered as evidence of a violation, you must provide your name, address, and phone number. If you choose to remain anonymous, the complaint will be considered non-actionable until a local Tobacco Education Specialist contacts the establishment and observes a violation firsthand.

If you have any questions or want to contact a Tobacco Education Specialist in your area, call 1-866-787-5247 or email infotobaccofree@mt.gov.
