I have to guess no. Can't imagine it would even be possible. On an issue like vaping supplies they might be looking at enforcing 50 different sets of complex rules, which could change constantly.
On Jul 1st the Indiana regs come into effect. Sellers outside the State can only sell juice in the State if a) the buyer is an entity registered by Indiana, and b) the seller is a vendor registered by Indiana. I think. And those rules are very fuzzy and badly written, they are likely to be spruced up down the road. Nobody is sure yet if they apply to foreign vendors, or to raw nicotine, for example.
I don't see any way DHS could stay up to date with that kind of mess, times 50. Even if they opened up a package, there is no way they could figure out if all the State rules were being followed.
That's the practical problem with doing it. I have no idea whether they are mandated to do it, or allowed to do it, legally, or whether they currently do it for other product groups. Doesn't seem likely though. Maybe someone here knows.
