Research Abstract	Occupational settings are considered to be a suitable situation to promote smoking control. In the present study the effectiveness of comprehensive smoking control was determined in workplaces. Questionnaire survey study about the exposure level of passive smoking, smoking prevalence and the smokers' intention for quitting smoking was carried out in two factories. Comprehensive smoking control (countermeasures against passive smoking, education about the adverse health effects of smoking, smoking cessation support) was introduced in one of the factories (intervention group) for three year and no countermeasures were enforced in the other factory (control group). The level of passive smoking among all the workers, smoking prevalence and intention for quitting smoking among the smokers were assessed. The same questionnaire study was done in the control group. Total ban of smoking was introduced in all shared premises and in most of the offices. One-third of the break rooms in the intervention group were improved by introducing a designated smoking area with independent ventilation. Two thirds of workplaces were covered by total ban or designated smoking area without leak. Occupational health personnel carried out strong recommendation for quitting smoking during periodical health examination and in factory news. The smoking prevalence decreased from 53.4% to 48.1% (1^<st> year), 48.2% (2^<nd> year), 44.8% (3^<rd> year) in the intervention group, while it changed from 61.7% to 61.6% (1^<st> year), 61.9% (2^<nd> year), 64.0% (3^<rd> year) in the control group. The total success of quitting smoking in the intervention group was 2.37 times higher than it was in the control group. These results will be applied to the comprehensive smoking control program that can be used in other enterprises.
