Another reason for the growing popularity of these cannabinoids and acetates is that, unlike heavily regulated THC, they are legal to use in most states. That’s because it’s extracted mostly from hemp-derived CBD, which is legal to farm across the U.S. But they still sit in a legal gray area. Hemp’s legality stems from the so-called federal farm bill (the Agriculture and Nutrition Improvement Act of 2018), which removed hemp and its byproducts from the list of controlled substances. The reason: Hemp’s low THC levels (less than 0.3%). The bill doesn’t mention Delta-8, Delta-10, THC-O or THC-V anywhere. Hemp advocates and others who sell it have used this loophole to legally market these products. As a result, it’s now the fastest growing product from the hemp industry.
