I can imagine a tax so high that it's effectively a ban, and a tax half that size that might be a compromise between black and white ban/no ban
We had in the UK the sugar tax which was an effective ban on added sugar in soft drinks - you can hardly buy any drink without artificial sweeteners now, all of the old formulations were taken off the market because they were uneconomical. However, it never prior received attention as a ban, it was always described as just a "tax".
Wouldn't be surprised to find out they smoke more than they used to with it being less scarce.
