That was my first reaction too. However, . . . .
The medical classification is already out of the question in this country. Thrown out of court. So, other countries saying it's healthy and a good way to quit smoking might just get it out of the tobacco classification here.
Then, US entities (FDA, city/state governments, etc) will be backed into a corner. It's becoming known as safe and a really good way to quit smoking. So, they can't do the banning or the sin tax thing. Not that they won't still for a while. Yet, they can't call it medical because that's already been thrown out of court.
What's left? They've lost. Checkmate. Although, I'm sure, they're still going to play it out to the bitter end.
And, Europe will eventually be forced to make it not need a prescription because of the US making it openly available.
Now, this may take 10 years to play out. So, having a vapocalypse stash is still a good idea. But, sooner or later . . . .
