Sooo your source is a sketchy website with a quote claiming they can be "functionally identical"(whatever that even actually means), but without any actual lab testing of the thc concentrations to back that up. Oh, and the article specifically mentions how these are at best questionably legal to sell, and the fda has actively warned against them.
Also, edibles are a completely different story than concentrates. You can pack a bunch of delta 9 in and still be compliant because the actual food aspect of the edible counts towards the total concentration. 15mg of delta 9 thc in a 5g piece of chocolate is no big deal. For a single "farm bill compliant" vape cart to have the same amount(by weight) of delta 9 thc in it as my 1g dispensary cart, though, it would have to be oh... about 10 ounces(edited to correct, originally said pounds) of other junk.
Good stuff.
No, they literally do not. Literally all of them have lab results on their websites. The first one had about 9mg/g, the second one about 1.4mg/g, and the last had none at all. Also, even counting delta 8 thc they were all still only in the 70-80% range. Regardless of whether the first two are legal or not(I have a feeling they're not and enforcement is just weak), even the stronger one is only a 10th of what I get for the same price. And I live in one of the most expensive legal states by far. Just get normal weed from a dealer at that point if you're in an illegal state, it'll be stronger.
