Four‐year follow‐up of smoke exposure, attitudes and smoking behaviour following enactment of Finland's national smoke‐free work‐place law

Abstract

This is the first follow-up study on a nationally implemented smoke-free work-place law. We found that such legislation is associated with steadily reducing ETS exposure at work, particularly at work-places, where the voluntary smoking regulations have failed to reduce exposure. The implementation of the law also seemed to encourage smokers to accept a non-smoking work-place as the norm.
