Workplace smoking restrictions, occupational status, and reduced cigarette consumption.

Reductions in workday cigarette consumption among indoor workers subject to different levels of smoking restriction were examined using representative population data for both blue-collar and white-collar workers. Regardless of whether workplace smoking bans were total or applied only to the usual work station, reported workday cigarette consumption was reduced by approximately five cigarettes per day compared with leisure-day consumption. This was in contrast to there being no difference between workday and leisure-day consumption among those who had no ban on smoking at their usual work station. This pattern of findings applied to all occupational-status groups, after controlling for sex and number of cigarettes smoked on a leisure day. These results are discussed with reference to potential public-health benefits and to implications for reduced retail sales of cigarettes.
