Hard to say the blackmarket vapes will recover
What exactly constitutes "blackmarket" vapes? The big brands you see -- Kingpen, SmartCarts, Bape Vapes, etc -- are these blackmarket? (I understand there are probably knockoffs of "name" brands, but a legit Kingpen cartridge, is that blackmarket?)
"black market" = folks making their own vape cartridges in their kitchens. they buy empty cartridges in bulk, fill them with home-made or bought liquid THC (often imported from china), sometimes add adulterants and dilutants, and sell their product out the back of their car/on a street corner, or, more likely, online via existing online marketplaces like etsy, ebay, etc. they are not a legit business, or even attempting to be. it's literally home-made vapes.
Kingpen is a legit company, so their
actual products are not black market.
the complication arises from fakes - above-mentioned cartridge-packers can easily copy the packing from legit brands and sell them to unsuspecting consumers.
