First statewide clean indoor air law

Illinois General Assembly adopts the first Illinois Clean Indoor Air Act.  The Act establishes separate smoking and non-smoking areas in restaurants and prohibits smoking in certain publicly accessible buildings, but preempts most communities in Illinois from adopting smoke-free laws.  Twenty-one municipalities with existing smoke-free laws are exempted from preemption and allowed to pass stronger laws.  Act goes into effect July 1, 1990.
