Oregon's Indoor Clean Air Act (ICAA) protects nearly every Oregonian from the health risks of secondhand smoke. The ICAA prohibits smoking in the workplace and within 10 feet of all entrances, exits and accessibility ramps that lead to and from an entrance or exit, windows that open and air-intake vents. In 2016, the Oregon legislature added "inhalant delivery systems" to the ICAA. This means that the ICAA applies to products such as e-cigarettes and vape pens.
Under the ICAA, smoking is prohibited in public places and workplaces, with few exceptions. Public place means any enclosed area open to the public. Place of employment means an enclosed area that is under the control of a public or private employer and that employees frequent during the course of employment.
The Oregon Health Authority (OHA) is responsible for enforcing the ICAA.
