Montana Clean Indoor Air Act Complaint of Violation Form

The Montana Clean Indoor Air Act (CIAA) requires all enclosed public places and workplaces to be smokefree (M.C.A. 50-40-104). It also requires all Montana businesses to prominently post no-smoking signs on all public entrances. In addition, tobacco products of any kind, including e-cigarettes, are not permitted on public school property at any time. (M.C.A. 20-1-220). Click here for more information about the state law.

Some localities in Montana may also prohibit the use of e-cigarettes in enclosed public places and places of work and prohibit smoking within a specified distance of building entrances. Visit the Montana Tobacco Policy Explorer to find out if your county has such a policy in place.

All complaints concerning violations of the CIAA are a matter of public record. In order 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 first hand.

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