Illinois Coalition Against Tobacco (ICAT) and partners successfully urge Illinois General Assembly to change statewide law to allow local communities to pass comprehensive smoke-free laws. Governor Blagojevich signs the law August 10, effective January 1, 2006. Shortly thereafter, Deerfield enacts a smoke-free ordinance, becoming the first community in the state to take advantage of renewed local control. In 2006, 30 Illinois communities used this new power to go smoke-free, the most ever in a calendar year anywhere in the U.S.
