Smoking ban
Evidence basis
Restrictions upon smoking in bars and restaurants can substantially improve the air quality in such establishments. For example, one study listed on the website of the U.S. Centers for Disease Control and Prevention states that New York's statewide law to eliminate smoking in enclosed workplaces and public places substantially reduced RSP (respirable suspended particles) levels in western New York hospitality venues. RSP levels were reduced in every venue that permitted smoking before the law was implemented, including venues in which only second-hand smoke from an adjacent room was observed at baseline. The CDC concluded that their results were similar to other studies which also showed substantially improved indoor air quality after smoking bans were instituted.
