Université Charles-de-Gaulle, Villeneuve dAscq, France The issue addressed in the study is: How do people perceive the combined effect of alcohol consumption and tobacco consumption on risks of cancer? The method used was an application of Information Integration Theory. Sixty-four participants of both sexes were asked to estimate the risk of cancer associated with a number of situations described by a tobacco-consumption level associated with an alcohol-consumption level. Participants were subsequently presented with a questionnaire concerning the way alcohol and tobacco consumption can cause cancer. Results showed that French adults apparently considered that indulging in only one of these two behaviours represents a maximum health risk. The two effects were seen to combine disjunctively which runs counter to current medical data. However, there was total contradiction between the participants answers to the questionnaire concerning their knowledge and the information integration task.
