This would be an extinction level event for many small to medium batch blenders and importers, but also it could be a shot in the arm for any remaining local B&M stores. Unfortunately, not many B&M tobacconists in my area.
Of course there’s the historical record of previous drug and alcohol prohibitions, if there is still a healthy demand then there will be money to be made and folks will be getting their Esoterica curtesy of some criminal “tobacco cartel”. Might even improve availability.
Psst... hey buddy, what to buy a gram of Stonehaven?
These are the good old days.
