Why did the City of Springfield adopt the Springfield Smoke Free Air Act of 2011?

Maybe this could help you

Explanation:

On April 5, 2011, Springfield voters passed the Springfield Smokefree Air Act of 2011. Following city charter rules, a group of citizens collected the necessary number of signatures required to place the issue on the ballot. The city charter states that City Council must then either pass the proposed language or send the issue to ballot, and Council elected to allow the voters to decide. Once the issue is placed on the ballot, citizens vote to pass or not pass the proposal. After a successful petition drive to repeal the law, a second vote was held on June 5, 2012. In that election, Springfield voters re-affirmed the law by a 2 to 1 margin. In May 2012, City Council voted unanimously to amend the law to include a handful of exemptions for on-stage theatrical productions and in pre-existing bingo parlors, private clubs, cigar bars, and retail tobacco stores that meet certain strict definitions.
