The law they passed in Indiana included giving
juice to someone for free. So in theory if you made juice and gave it to a friend you would face the same penalties as a store selling the stuff without meeting the State requirements. I don't think anyone was actually charged though. And the law might have been cancelled anyway.
The Indiana law had some pretty interesting parts to it. It required any vendor mixing juice to hire a certified security service who would monitor the operations 24/7 (I guess they thought breaking to get nic would be common) as well as review safety features and standards of the vape shop / mixer (back when house juice was still a thing). Where it got really odd was there was only one security company "certified" to perform all those duties, and that firm would only accept something like 3 shops of their choice from the applications and be "unable" to take on any additional vendors. So the single security company controlled the few stores that could stay in business as usual (other than the fees) but everyone else was out.
Of course that security firm has family connections to the state senator who pushed it through, but hey, they were just trying to do the right thing to protect Indiana citizens, right? It was signed into law by then Governor Pence, our current VP.
Of course it was so ludicrous and an obvious conflict of interest action that it was tossed out by a federal court. But the damage was done as the vape businesses of Indiana felt beat up, spent too much on legal fees, and in the end it did to my knowledge close some shops all together. There were other restrictions and regulations attached to that bill and I'm a little fuzzy as it was several years ago, but I sure remember that attempt to grab the entire vape business of Indiana by a small group of connected people.
Never saw any statements from Pence about why he signed it and how he felt about it when it was tossed out in court.
