A Treasury report has admitted that smoking saves the Government money because smokers die earlier and pay more in tobacco tax than their health problems cost.
The regulatory impact statement on tobacco taxes prepared ahead of the Budget said smokers' shorter life expectancies reduced the need for superannuation and aged care.
"When the broader fiscal impacts of smoking are considered ... smokers are probably already 'paying their way' in narrowly fiscal terms."
In last week's Budget, Associate Health Minister Tariana Turia introduced tobacco levies that will increase the price of a 20-pack of cigarettes to more than $20 in four years.
The charges would increase the Government's tax take from tobacco from $1.3 billion to around $1.7 billion by 2016.
