EDIT: In hindsight, I think I should've looked into posting this in a different community.. It's closer to a silly "innovation".. soo.. is this considered FUD? I also don't support smoking or vaping, especially among kids. Original title had "privacy-violating" before the "solution".
The black market carts in question were specifically weed vapes, not nicotine vapes, which are actually more different than you may think. Not only was that not a problem with nic vapes ever, it hasn't been a problem with homemade weed carts since that one incident (which IIRC was caused by one singular dumbass in WI or MN) either.
There still are "black market carts" for both weed and nic, but they've learned not to use vitamin a and are now mostly just regular ol' knockoffs.
That said however, that's why it's always better to use a refillable vape with a bottle of juice over a disposable, they usually don't counterfeit bottles opting instead for dispos, and even if they did it's easy to make your own juice so you know what you put inside.
