In Ireland they implemented a smoking ban in March 2004 and researchers have noted a marked increase in air quality as a result. The research reports that an all out smoking ban in the workplace is wonderfully successful in reducing exposure to harmful particles, and, or course carcinogens. This Irish study supports previous research.
The workers were all given lung function tests before the ban came in and a year later….The bar-workers said they were exposed to around 40 hours per week before the ban came in, falling to 25 minutes afterwards – a 99% decrease in exposure.
And lung function tests improved dramatically in non-smoking barmen post-ban.
