Analysis of a smoking policy in the workplace.

Following implementation of the smoking policy, an overall decrease in tobacco consumption was reported among 33% of the employees; of these, 32% quit completely. Smokers who reported smoking more than one pack of cigarettes a day were three times more likely to decrease consumption than those who reported smoking one pack or less a day. Among those who decreased their tobacco consumption, 43% associated this decrease with the policy implementation. A notable inverse relationship existed between smokers' tobacco consumption and attitudes about the policy: as cigarette consumption decreased, attitude about the policy increased positively.
