↵2-150 All models are sex and age adjusted (except models 6 and 8). Model 1: smoking as cumulative number of years smoked, alcohol in five categories (non-drinker, occasional, low consumption, high consumption, heavy drinker). Model 2: smoking as ever/never, alcohol in five categories. Model 3: number of years smoked, number of years of alcohol drinking. Model 4: cumulative lifetime number of cigarettes, cumulative lifetime grams of alcohol. Models 5 and 8: cumulative lifetime number of cigarettes, alcohol in five categories. Model 6: ever smokers. Model 7: smoking as ever/never, years of alcohol drinking. Only seven women had ever smoked, and only seven men were never-smokers.
