This paper reviews data regarding the effects of the legislation banning smoking in enclosed public places, including workplaces, restaurants and bars which entered into force in several countries of Europe starting with the year 2004. The source of data is represented by articles and short information published in peer reviewed journals or in electronic format between the years 2005 and 2008. Highlights include a consideration of the effects of these laws on the attitudes of the population regarding their implementation, exposure to passive smoking in public places as well as the scientific evidence on the public health and economic impact of these laws. The results of smoking ban in public places observed in several parts of Europe support initiatives in many countries toward implementing smoke-free legislation, particularly those who have ratified the Framework Convention on Tobacco Control, which calls for legislation to reduce tobacco smoke pollution.
