There was a situation like this in DC for cannabis. There was a ballot measure passed that legalized recreational use and gifting but selling weed was still illegal. So there were lots of “gifting” shops where they would sell things like stickers or t-shirts and then offer you a “free gift” of cannabis. It was sort of tolerated for a little while but the authorities started cracking down and required them to get licensed for medical maraijuana sales. [1]
