It's worth understanding the incentives of the businesses profiting from tobacco to help understand how it is so pernicious to society. I don't think the author is wrong to highlight the profits to businesses.
The health cost is externalized for the producer because it is shifted to the consumers.
It also significantly reduces costs in terms of social security.
To me it sounds too much like one of many myths the tobacco industry spread.

I think if you factor in not just healthcare but benefit payouts and additional taxes paid we find smokers are persecuted minority that more than pays their way. And they have a good chance of really suffering those last 10 years of their shorter life.
So these are the years people go from productive to a net societal expense as they collect social security and Medicare.
I guess we don’t really know. But I think it’s probably true that smokers don’t end up costing society anymore than non-smokers overall.
Saying that, smoking is a ridiculous thing and I’ve seen how it not only steals years but makes those final 10 years progressively worse and torturous.
There's a lot of casual smokers who never become that pack-or-two a day kind of extreme addict one can clearly attribute their smoking to their lung/mouth/throat cancer.
But they are still more likely to develop some kind of ailment from their lighter smoking, as it's equivalent to frequently subjecting your body to a poison that enters the bloodstream. Especially since it's not necessarily going to be a respiratory cancer, attributing cause becomes ambiguous enough to to make all the stats unreliable at best.
Consider the fact that some american cities ban wood burning fireplaces/stoves as a public health measure. And that's diffuse atmospheric smoke, nobody is sucking directly from the stacks day after day, year after year.
An obese person dying of a heart attach in their mid-50’s is a net positive to society since they have consumed limited health resources, collected few social benefits, and have contributed many social dollars.
Smokers die young before they collect most social benefits, plus they pay so many taxes. Smokers are a net benefit to society much like lotto players.
