CIAA meaning in Governmental ?

The following is a list of smoking bans in the United States.

The United States Congress has not attempted to enact any type of nationwide federal smoking ban in workplaces and public places. Therefore, such policies are entirely a product of first-level jurisdictional, local criminal, and occupational safety and health laws.

In 1995, California was the first state to enact a statewide smoking ban for restaurants. Throughout the early to mid-2000s, especially between 2004 and 2007, an increasing number of states enacted a statewide smoking ban of some kind. As of July 2018, the most recent statewide smoking ban is Alaska's, which was signed into law on July 18, 2018, and went into effect on October 1, 2018.

As further detailed in this list, smoking laws vary widely throughout the United States. Some places in the United States do not generally regulate smoking at all, some ban smoking in certain areas and not others, and some ban smoking nearly everywhere, even in outdoor areas (no state bans smoking in all public outdoor areas, but some local jurisdictions do). As of July 1, 2017, according to the American Nonsmokers' Rights Foundation, 81.5% of the U.S. population lives under a ban on smoking in "workplaces, and/or restaurants, and/or bars, by either a state, commonwealth, or local law", and 58.6% live under a ban covering all workplaces and restaurants and bars. A smoking ban (either state or local) has been enacted covering all bars and restaurants in each of the 60 most populated cities in the United States except these ten: Jacksonville, Memphis, Miami, Las Vegas, Nashville, Oklahoma City, Philadelphia, Tampa, Tulsa, and Virginia Beach. New Hampshire allows smoking in some private member's clubs where alcohol is served.
