Morbidity and mortality attributable to alcohol, tobacco, and illicit drug use in Canada

Objectives. This study estimated morbidity and mortality attributable to substance abuse in Canada. Methods. Pooled estimates of relative risk were used to calculate etiologic fractions by age, gender, and province for 91 causes of disease or death attributable to alcohol, tobacco, or illicit drugs. Results. There were 33498 deaths and 208095 hospitalizations attributed to tobacco, 6701 deaths and 86076 hospitalizations due to alcohol, and 732 deaths and 7095 hospitalizations due to illicit drugs in 1992. Conclusions. Substance abuse exacts a considerable toll on Canadian society in terms of morbidity and mortality, accounting for 21% of deaths, 23% of years of potential life lost, and 8% of hospitalizations.
