Smoking costs the NHS five times as much as previously thought, researchers have calculated.
Treating disease directly caused by smoking produces medical bills of more than £5bn a year in the UK.
In 2005, smoking accounted for almost one in five of all deaths and a significant amount of disability, the Oxford University team said.
The British Heart Foundation who funded the research said tighter regulations were needed on the sale of tobacco.
The figure of £5bn in 2005-06 equates to 5.5% of the entire NHS budget.
