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.
