These are actually some old findings, subtitled Prevention No Cure for Increasing Health Expenditure. The basic idea being that, although the actual health related costs of smokers (and obese people) are higher, because non-smokers and the thin live longer, they run up higher costs in total health care expenditure during years when they are retired.
The basic idea being that people are productive until about the age they retire, and during that time are contributing. After that time they are basically draining what they already produced, since smokers produce just as much as non-smokers, but die earlier, they leave the world with the greatest contribution!
