I've read that smoking related illnesses cost less money overall to treat than average. As an extreme example, if someone went around disintegrating people with an orbital laser, this would clearly reduce overall heathcare spending. So in this analogy, smoking is the equivalent of an orbital laser that (plausibly) causes people to die before they develop an even more expensive-to-treat healthcare situation.

If you've read it, then please provide the citation.

Smoking not only has its own direct impacts (lung cancer, emphysema), but it also makes many other conditions far worse than they would be without smoking, and therefore more expensive to treat.

I don't think this analogy works, the space laser is instant and does not spread to non-targets. Smoking does reduce the average life span, but not to zero. In the remaining time, healthcare costs are increased on top of anything expensive they'd develop naturally. Smoking also causes serious diseases in non-smokers and kills 1.3 million non-smokers per year. https://www.who.int/news-room/fact-sheets/detail/tobacco
