Smokefree Policies Improve Air Quality in Hospitality Settings
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 smokefree 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 smokefree 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.
