There are reasons why some people may want to refrain from consuming any and all THC. If you’re a competing athlete, a first responder, or simply interested in avoiding even trace levels of THC for personal reasons, THC-free CBD oil products could be ideal. Because isolated CBD supplements are more concentrated, they’re also more optimal for those interested in a higher daily CBD intake.
Some individuals have been found to have mutations on the CNR1 gene, which is responsible for coding the CB1 receptor (a type of receptor in cells throughout your body that interacts with cannabinoids). Issues with the CNR1 gene can ultimately result in a poorly functioning endocannabinoid system, which is an important variable when figuring out how to use CBD oil.
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.
Though a CBD latte might not do much for you — at least not beyond what caffeine and the placebo effect combined can do, which isn’t nothing — it’s also probably harmless in most cases, says Carson, and may even have positive benefits we aren’t yet aware of. “I suspect there’s probably some antioxidant benefit to CBD like there is with coffee,” says Carson. “There’s tons of good things in coffee that we still don’t fully understand, and I think the marijuana plant is much the same way.”
While there are producers who will tell you the difference between legal and illegal CBD comes down to whether your batch is derived from marijuana or hemp—both are plants in the cannabis family, but hemp contains very little THC compared to marijuana—the truth is that even hemp isn’t legal everywhere. In Massachusetts, for example, you’re allowed to grow marijuana at home, but it’s still a crime to grow hemp.

In the current market space is there much difference in cost, in bulk, between 99+% pure CBD from the different sources being discussed? IOW between high-cbd cannabis, and low-total-cannabinoid “industrial hemp”, and hemp grown for seeds not fiber? Extraction from high-cbd cannabis would seem easier as you have to work with less plant material per unit of end product, but then it costs a lot less per lb plant material to grow a huge field of hemp. So, how does it land these days?
