September 30, 2011 (Atlanta, Georgia) — Cigarette smoking among working US adults is far more common than average for those with occupations in the construction, restaurant, and transportation industries, and far below average for teachers, scientists, and lawyers, suggests an analysis published in today's Morbidity and Mortality Weekly Report that put the age-adjusted national mean at 19.1% [1].
The analysis is based on National Health Interview Survey (NHIS) data for 2004 to 2010, and shows a smoking prevalence in some occupations well over double the target of <12% put forth by the government's Healthy People 2010 initiative [2], according to the report.

"Although workplace policies or exposures to secondhand smoke were not assessed in this study, national surveys have shown that the proportion of smoke-free worksites was lower in agriculture, forestry, fishing, mining, and construction and higher in professional and related services."
