I don't see why a smoker's desire to smoke should supersede a working man's need to be free of the risk of lung cancer and heart disease.

Irish Pubs Under Smoke-free Law in Ireland Show 91% Lower Indoor Air Pollution T

A survey of air pollution levels in "Irish pubs" around the world has found that indoor air pollution in authentic Irish pubs in Ireland, where a smoke-free law has been in effect for two years, is 91 percent lower than in "Irish pubs" located in other countries and cities where smoke-free laws do not apply. Researchers from Harvard School of Public Health (HSPH), Roswell Park Cancer Institute and health authorities in Ireland collaborated on the project that assessed air samples from 128 "Irish pubs" in 15 countries in North America, Europe, Australia and Asia.
