Well, while you search for the link to that study and share it with us, we can spend time reading this chapter from a report about the tobacco cost in Australia (updated August 2021) that lists net present value of "healthcare costs avoided" being merely 2/3 of the lost productivity due to premature deaths alone. Total tangible costs come out to 9.5 times greater than those savings, if you try to put a cost on the suffering caused by premature death and ill health the costs are 50 times greater than the savings from healthcare avoided. https://www.tobaccoinaustralia.org.au/chapter-17-economics/17-2-the-costs-of-smoking https://www.tobaccoinaustralia.org.au/chapter-17-economics/1...
