This ban also includes flavored cigars, which most users only smoke occasionally. But even so, why is society bothered with someone's individual choice to smoke a menthol cigarette away from others? I don't see the "external effects" you're alluding to, so it feels like the "long tail" is small in magnitude.

If I have to take a guess, you might be thinking of healthcare costs and having to subsidize smokers. But if that's a concern, I feel we should avoid universal healthcare proposals (like Medicare for All) and instead let people choose what insurance coverage they want from private companies, from a menu of choices, so that they pay for what the coverage they want based on who they are and the habits they have. I suggest this path because everyone has a different idea about what they want covered. Some may not want to subsidize smokers, some may not want to subsidize abortions, some may not want to subsidize healthcare for the obese, some may not want to subsidize puberty blockers for children, and so on.

Ultimately, all of this is leading us back to what I feel the US got right in the past - favoring choice, control, and responsibility at the individual level instead of increased government size, regulation, and paternalism.
