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.
Classes decide to be a non-smoking class for a period of six months. The programme is carried out as a class
activity. All partners point out on their materials that the participation in the program is voluntary for
the pupils and classes.
Pupils sign a class contract and an individual contract promising not to smoke during the competition. The
contracts serve to underline their commitment.
The responsibility for the control of smoking lies mainly with the pupils themselves: pupils monitor their
smoking status and report regularly, whether they have smoked or not.
Classes which refrain from smoking for that period of time are rewarded: They participate in a national as
well as a European prize draw, in which they can win a number of attractive prizes.
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.
Body fat: People who have higher body fat retain THC for a longer period of time. THC storage options are limited for thin users.
At the time of the test, you should drink plenty of water.
THC will be excreted quickly by fast metabolizers.
How often do you exercise?
Usage method and frequency: THC is cleared faster by infrequent users than by persistent users.
The method of detection that was used (blood, hair, saliva, or urine).
