Several studies have estimated the numbers of deaths caused by tobacco use in Australia;1-3. Some of the key findings are presented in this section.

3.30.1 Estimated mortality and morbidity from tobacco use, 2011—the Australian Institute of Health and Welfare (2016)

 

The Australian Burden of Disease study estimated that smoking caused a total of 18,762 deaths in 2011, or more than 1 in every 8 deaths (12.8%).2   

Table 3.30.1 shows the years of healthy life lost (‘disability-adjusted life years’, or DALY) from death and illness due to tobacco use in Australia in 2011.

Lung cancer was the leading cause of death and illness due to smoking, followed by chronic obstructive pulmonary disease, coronary heart disease and stroke (Table 3.30.3).

3.30.2 Estimated mortality from tobacco use, 2010—Peto et al methodology

Estimates of deaths caused by smoking in Australia have been calculated by Peto et al for 2010,3 using a methodology first described in 1992.4 Extrapolating from WHO mortality for lung cancer and other diseases, and using UN population data, Peto et al estimate that a total of 22,900 deaths were caused by active tobacco use in Australia in 2010 (Table 3.30.4).3 These estimates are likely to be conservative, because they do not include any deaths in individuals aged under 35 (including infants). About one quarter of all deaths due to smoking (or 6,100 of 22,900) occur in individuals aged between 35 and 69, who lose, on average, about 23 years of life.3   

The robustness and wide applicability of this methodology has enabled Peto et al to expand their calculations to worldwide estimates of mortality due to tobacco.3 (See Section 3.36 ).

Figure 3.30.1 shows that of all deaths due to tobacco, 39% are cancer deaths, 29% are due to vascular diseases, and a further 21% are caused by respiratory disease.

3.30.3 Estimated mortality from tobacco use in Australia in 2004–05 —the Department of Health and Ageing, 2007

The most recent of a series of reports by the Department of Health and Ageing—first published in 19905-8—estimates that almost 15,000 people died due to tobacco use in the financial year 2004–05.1 The methodology used in these reports has calculated ‘attributable fractions’ for the proportion of deaths due to specific diseases caused by tobacco, based on extensive literature reviews and developed progressively since the first publication.

By this methodology, it was estimated that in 2004–05, tobacco use caused a total of 14,901 deaths.1 Of these deaths, 14,790 were attributable to active smoking (including 56 deaths in infants subjected to maternal smoking) and 113 occurred in adults due to exposure to secondhand smoke (Table 3.30.1).1 As discussed in Section 3.28, smoking also confers a protective effect against a small number of diseases. It was estimated that in 2004–05, smoking prevented death from these specific diseases in 148i smokers. However it should be noted that prevention of one disease in one individual does not protect against other diseases caused by smoking in the same individual; there is no sound medical basis for taking up or continuing smoking in order to prevent or ameliorate the process of any disease.

The same study also quantified deaths caused by other drug use in Australia. Table 3.30.2 shows that most drug-caused deaths in tobacco are caused by tobacco. Almost 90% of deaths due to drugs in 2004–05 were caused by smoking compared with 6% from alcohol and 5% from illicit drug use.1
