Montana Expands the Clean Indoor Air Act to Include E-cigarettes 

 Using e-cigarettes, or vapes, is no longer allowed in Montana’s public indoor spaces. This is the result of Senate Bill 390, a bill passed by the Montana Legislature and signed into law by Governor Greg Gianforte on May 8, 2025. The new law went into effect immediately.

 The Clean Indoor Air Act now prohibits smoking or vaping nicotine, marijuana, or any other substance in workplaces or indoor public places in Montana. The purpose of the Montana Clean Indoor Air Act is to protect the health of Montanans by prohibiting smoking in enclosed public places and places of work. The Act recognizes the fundamental right of nonsmokers to breathe smoke-free air and establishes that the need for clean air takes precedence over the desire to smoke.
