Secondhand Smoke and Casino Dealers
Simply working in a casino does not mean dealers must gamble with their health. There is nothing lucky about developing a respiratory illness, lung cancer, or heart disease—especially if you are a healthy nonsmoker. Results of new research conducted by the National Institute for Occupational Safety and Health (NIOSH) on secondhand smoke—the exposure of non-smokers to tobacco smoke—confirm that dealers at the casinos investigated were exposed to secondhand smoke. Secondhand smoke, also called environmental tobacco smoke, is a combination of smoke given off by the burning end of a tobacco product and the smoke exhaled by the smoker. Secondhand smoke is made up of approximately 4,000 chemicals, of which about 40 are known to cause cancers.
