The Montana Clean Indoor Air Act was passed in 2005, and this year Montana has taken another important step to protect community health with the passage of Senate Bill 390 (SB 390). SB 390 expands the Montana Clean Indoor Air Act to include e-cigarettes and other vaping devices. This legislation closes a critical gap in the 20-year-old law, ensuring that residents and workers across the state are safeguarded from harmful exposure to e-cigarette aerosol in indoor public spaces and workplaces.
