[Health warnings on cigarette packets. An overview].

The implementation of health warnings leads to continuous dissemination of the latest scientific findings on the health consequences of smoking. In combination with other recognized effective tobacco control measures, a lower consumption and an increased quit-rate are thus to be stimulated. The effectiveness of health warnings depends on their content as well as on their design and size. Thus, large warnings are by far better than smaller warnings. The same applies for warnings that are placed on the front of cigarette packets. Warnings that incorporate pictures are considerably more effective than warnings based solely on text. The combination of pictures and text format is most effective. International experience shows that the dissemination of Quitline phone numbers in combination with health warnings on every packet clearly improves the effectiveness and broad reach of smoking cessation advice via Quitlines. The implementation of pictorial health warnings combined with the imprint of the phone number of the Quitline of the Federal Center for Heath Education is highly recommended in Germany.
