In 1992 the Public Health, Social and Safety Policy Services of Bologna Municipality, passed the project "TOBACCO-FREE BOLOGNA". Since then they have been working hard to make people aware of the serious harm caused by smoking, to help them to change their habits connected with it and to follow a definitely healthy life style. The plan, involving both, the Municipality, the Health fittings, the School and the Voluntary Assistance Bodies, addresses all the citizens so that they stop smoking and build a healthier city. It is a section of the 1994 "Healthy Cities International Plan, by W.H.O. (World Health Organization) or better, of the European Action Plan against nicotinism. Our Plan aims to improuve our life quality in a healthier environment. For this very reason, the city of Bologna has joined the "Healthy City Plan" and later the "Multicity Action Plan Tobacco-free Healthy Cities", whose members are 14 European Cities which are working hard to fight nicotinism and to exchange both their working methods and goals. The fifth Business Meeting of the Representatives of the Plan Member Cities, was held in Bologna in March 1995. Anything a city is able to do to improve its own citizens’ health, and not only what concerns strict measures against smoking, is very important. The closer cooperation among different bodies (cultural, social, institutional, yielding) the more effective the area: all of them should work together to help people to get aware of the importance of any measure taken in defence of everybody’s health. Any step on that way has to be seen as the promise to a more human, civil and soc ial development. In our plan, the youths are our preferred interlocutors, they are the ones who can help us to reach the highest goals. That is why our clever team, along with the pupils of the "Scuola Media Besta" - Bologna has made this booklet every middle and high school student should read carefully. No doubt all the readers will join us in thanking them.
