Three experiences familiar to heavy drinkers were related to mortality over a 12-year and 23-year follow-up period. Weibull survival models were used to test the significance of associations and to produce estimates of relative risk. Age and marital status were controlled for by including them into the models, and social class by analysing the data separately for the 462 upper and 1614 lower social group males. The experiences studied were the occurrence of alcohol intoxication, that of hangover, and that of hangover drinking. All three had some prognostic value. Significant associations were found for mortality from pulmonary tuberculosis, cancer of the lung, digestive cancer, coronary heart disease, respiratory diseases, gastrointestinal diseases, injuries, and all causes of death. The number of significant associations found over the 23-year follow-up period was smaller than over the 12-year follow-up period.
