This study concerns the geographical relationships between alcohol consumption per capita; smoking and death from cirrhosis of the liver and cancer of the oesophagus in persons of 15 years old and over in Quebec. First, the geographical distribution of variables is analysed. Secondly, we have used methods of correlation and regression in order to evaluate their relation to each other. In the latest case we have chosen the logistic regression model to investigate the simultaneous effects of alcohol and tobacco. The results show that alcohol consumption is closely related to mortality from cirrhosis of the liver. Moreover, there was no significant relation found between total alcohol consumption and oesophageal cancer. These findings can be applied to cases of consumption of wine and spirits.
