PHOENIX (CBS5) -
This year, "World No Tobacco Day" - celebrated May 31 - was a date of special significance for Arizonans. It helped mark the five-year anniversary of the Smoke-Free Arizona Act, a landmark voter initiative that prohibits smoking in most enclosed public places.
Within the past five years, Arizona has been a national leader in reducing tobacco use. Since the law became effective in 2007, an estimated 230,000 Arizonans have quit using tobacco.
A 2010 statewide survey showed that more than 80 percent of Arizonans and 70 percent of business owners appreciate smoke-free laws.
