Spotty...
As far as the dooming, a few businesses have closed, Provape being the latest. But various States have done some ugly things.... some of which may be changed back, due to court or legislative means.
But in this world of alternative facts, their innuendo takes precedence over science... Yeah, some kid tried an
ecig once, so now they're a "user." Like saying I tried vodka once, so I'm a Russian....
One of the key "filing" dates did get pushed off to later this year (or it would have been in effect already), so a lot of people still have their heads comfortably buried in the sand. And, in spite of what many of us here have been saying for, literally, years, many of those will still be totally surprised...
