Data for Ireland on the estimated number of deaths directly attributable to smoking are contained in the publication. "Mortality from Smoking in Developed Countries, 1950-2000" by Richard Peto and others. Figures are only available for the years 1975, 1985, 1990 and 1995 and are reproduced in the following table. The estimates are based on an indirect method which uses the results of epidemiological studies of mortality in smokers versus non-smokers in the United States to assign proportions of total mortality due to tobacco for each relevant cause of death.
