We extracted data on average earnings from the ILOSTAT database of the International Labour Organization. We calculated life-course cigarette expenditures using cohort life expectancies and inflation, and converted these expenditures into net present value terms using a 3% social discount rate.</p><p><strong>Findings: </strong>The average age of adult cigarette smokers in our sample was 40 years, and their average expenditure on cigarettes was equivalent to 7.2% of annual average earnings. Given an average life expectancy of 55 years at the age of 15 years, we estimated an average life-course consumption of 217 752 cigarettes and a full life-course expenditure of 8481 United States dollars (US$) in net present value terms, more than twice the current average annual earnings of workers.
