The Science of Second-Hand Smoke

Dr. Moira Gunn speaks with Dr. Stan Glantz, professor of medicine at the University of California, San Francisco, and Jim Rapace, a health physicist with the Environmental Protection Agency in Washington, D.C., discuss the effects of second-hand smoke with Dr. Moira Gunn. Together they relate the decade-long effort at the EPA that resulted in the landmark 1992 report on the effects of second- hand cigarette smoke. While that report concentrated mainly on second-hand smoke's potential for causing cancer, most scientific studies since that time have indicated an even greater public health problem -- heart disease. Dr. Glantz, a member of the California State Scientific Advisory Panel on Toxic Air Contaminants, discusses the immediate and long-term effects of second-hand smoke on individuals, as well as some of the grass-roots citizen action efforts that have sprung up in response to smoke as a pollutant.
