Smoke-Free Policies Improve Air Quality in Hospitality Settings

Overview

  • Breathing secondhand smoke from cigarettes, cigars and other tobacco products that burn has immediate, harmful effects on health (see Health Effects of Secondhand Smoke).
  • Many studies show that comprehensive smoke-free laws that prohibit smoking in all indoor areas of worksites and public places, including bars and restaurants, improve air quality and reduce exposure to secondhand smoke.1-14
  • These studies usually measure levels of respirable suspended particulates, or RSPs, before and after a smoke-free law is put in place to measure any change.
  • One specific type of RSPs that are assessed in these studies is 2.5 microns or less in diameter (PM2.5).
    • These particles are easily inhaled deep into the lungs.
    • They are released in large amounts when tobacco products, such as cigarettes and cigars, are burned.
