Clean Indoor Air Act Amendments
Effective July 1, 2025, Idaho amends its Clean Indoor Air Act to add and revise definitions and to clarify requirements regarding sign posting. Under the amendments, tobacco products means any substance that contains tobacco, including cigarettes, cigars, pipes, snuff, smoking tobacco, tobacco paper or smokeless tobacco. It is presumed that a lighted cigarette, cigar or pipe contains tobacco.
In addition, "no smoking" signs must be appropriately sized, conspicuous, legible with letters at least one inch in height, unobscured and placed at a height and location easily seen and read by persons entering or within the posted area. Signs may contain information such as the international smoking and no smoking symbols and references to the Idaho Clean Indoor Act.
