Correct Answer: Each batch of flower AND finished product should be tested by a state certified testing facility for potency, legality and safety. These test results should also be made available to any patient that requests them. These tests should certify 3 things: the amount of CBD contained in the product, the amount of THC in the product (the starting hemp plant material must test below 0.3%), and the lack of mold or toxic pesticides.
What’s more, CBD vape oils require additional equipment. In order to transform the oil into vapor, you’ll need an e-pen or vaporizer. This means an extra investment on top of the vape oil itself. I therefore recommend that, if you’re a first-time user, you try a more accessible and affordable CBD product type to make sure it’s the right supplement for you, before graduating to vape oil.
When buying industrial hemp CBD, i.e. everything you see outside of a state-licensed dispensary, all bets are off. Because the legality of industrial hemp is in flux, companies that use hemp CBD operate in a gray market with no oversight. Nick Mosely, Chief Science Officer of a testing lab in Washington explained that “everything currently on the market for interstate CBD sales is unregulated.” And product labels can be wildly different from what's actually contained in the product. Multiple studies of CBD oil sold online have repeatedly exposed brands that misrepresent purity and CBD dosage levels.
To get almonds from an almond tree, you can just shake the tree. To get juice from an orange, you can simply squeeze the fruit. But getting CBD oil from hemp is a much more complicated process. The cheapest and easiest ways to extract CBD oil from hemp commonly involve harsh solvents that can leave chemical residue in the CBD oil. The best, and most reliable extraction method, uses carbon dioxide (CO2) under high pressure and extremely low temperatures to pull out as much CBD as possible without introducing contaminants. Once the CO2 is no longer under intense pressure, it simply evaporates, leaving virtually no trace of extraction on the CBD oil.
