A study commissioned by the Department of Health and Ageing in 2003 showed quite spectacular long-term returns on investment and cost savings through the Preventive action of tobacco control programs, road safety programs and programs preventing cardiovascular diseases, measles and HIV/AIDS.[12]

For example this report estimated that the 30% decline of smoking between 1975 and 1995 had prevented over 400,000 premature deaths[13] and saved costs of over $8.4b, more than 50 times greater than the amount spent on anti-smoking campaigns over that period.

The recent US study Prevention for a Healthier America shows that for every US$1 invested in proven community-based disease prevention programs (increasing physical activity, improving nutrition and reducing smoking levels), the return on investment over and above the cost of the program would be US$5.60 within five years.[14]
