Smokefree Class Competition A European school-based smoking prevention programme

How Long Does Wax Pen Stay In Your Urine?


Co-funded by the European Commission from 1997 to 2009, a network of partners from up to 22 European Countries engaged in implementing a school-based intervention to prevent smoking: the “Smokefree Class Competition” (SFC). The network was co-ordinated by the Institute for Therapy and Health Research (IFT-Nord), Germany.


The idea of SFC was first established in Finland in 1989. SFC is especially conceptualized for schools and carried out as a competition for pupils aged 11 to 14 years. The concept and materials are attractive and can be easily integrated in many different subjects.

Even though the program is suited to the needs and circumstances in the individual countries, the methods applied are similar in all participating countries. The degree of flexibility placed in a fixed conceptual frame enables comparison and sharing of data and experiences thus contributing to uniformity and consensus of the approach across the states.

All countries agree on a basic set of rules for the project implementation.


Several process and outcome evaluation studies have been carried out in the European participating countries demonstrating high acceptance and practicability of the program as well as giving hints for effects of participation in the competition in reducing smoking among adolescents. In addition, a cost-effectiveness study shows that SFC is a cost-effective school-based intervention.
