People have been adulterating drugs for eons, and cannabis flower is certainly no exception. Just a quick Google search of "how to make weed look better" demonstrates such. As I said earlier in this thread, vitamin E is common preservative added to botanical terpene blends, which are definitely being sprayed on lower grade cannabis flowers to give the impression of being more flavorful. If it's truly as simple as "there's no vitamin E acetate added to flowers," and my concentrates are made from pressed flowers, then we could just as easily deduct that concentrates are clean too. Obviously it's way deeper than that. I don't like the conflation that concentrates = vape pens because that's misleading. Most forms of concentrates don't work in a pen without proper processing. Most concentrate users on FC produce their own from flower.
