The Smoke Free Illinois Act (410 ILCS 82; Public Act 095-0017) is a comprehensive anti-smoking law that took effect in Illinois on January 1, 2008 (2008-01-01), and bans smoking in most buildings and vehicles used by the general public, used as a place of employment, or owned by the government or other public body. It also requires "no-smoking" signs, bans smoking within 15 feet (4.6 m) of openings in the targeted buildings, and requires at least 75% of rooms in each hotel to be non-smoking. It replaced the more limited Illinois Clean Indoor Air Act (410 ILCS 80).
