Three months later, Norway joined Ireland in enacting a total workplace ban. One year after these bans took effect, reports from both governments lauded the health effects of the measures.

In March 2005, the Irish Office of Tobacco Control released a study of worker health, which was assessed before the ban and again one year after. Researchers found that air quality in bars had improved dramatically, with larger airborne particulate matter falling 53 percent and smaller particulate matter falling 88 percent, settling at a level similar to that found in non-smoking homes. Moreover, levels of carbon monoxide in non-smoking workers' blood decreased 43 percent.

The Norwegian study found similar positive results: airborne particulate matter declined 70 percent in bars and restaurants, and nicotine levels in the urine of non-smoking workers decreased nearly 90...
