The only study that has tested the bioavailability of inhaled CBD is from 2014; it found a bioavailability of about 25 percent for 100 mg and 200 mg doses of CBD using a Volcano vaporizer. (The topical lotions are even less studied; there have been no clinical trials on them at all.) This is more efficient than ingesting CBD, in the same way that vaporizing THC is more efficient than eating it. To get an effect, you should ingest a different amount of CBD than you’d inhale ... but how much is that? How much is too much?
As a representative with 2 companies that have CBD on the market and as a person with intractable pain and multple painful problems wirth my spine I can say that cbd does not work for everyone. It does nothing for me or for my mil who has a cancer like growth impeding her ability to swallow and has undergone radiation to shrink it. Everyone has a chemistry that’s personal to them for some it helps but for many it does not. With that in mind it’s a 50/50 chance of it helping and until you come out your pocket you’ll never know. Buyer beware.
I tell several sellers of CBD food and drink what I learned from Blessing and ask what they think. “Return customers who come back, and swear by it and love it, buy two at a time to stock up for the week because they do find it to be very helpful,” says Tavares. Clancy echoes this: “We rely a lot on consumer feedback and testimonial, and generally it’s positive when taking that minimal amount. Now, that very well could be a placebo effect, but either way, people have come back and reported significant benefits when it comes to easing social anxiety.”
If you want a daily CBD therapy that actually tastes like a “proper” cup of java, on the other hand, you really do need to set yourself up with a well-made, properly infused CBD roast. The best cannabis-incorporating master roasters (which we’ll talk about below) have spent years devising and perfecting specific roasting processes that allow for efficient CBD infusion, without having to sacrifice any traditional coffee taste.
We don’t know how CBD affects the brain in any kind of depth. We don’t know which doses and delivery methods are best for different outcomes. We don’t know how CBD interacts with most other drugs or foods. We don’t know the differences between the effects of isolates and full-spectrum preparations. We don’t even know how many cannabinoids there are. California, for what it’s worth, seems aware and concerned about this whole thing.
For ingested CBD, that fat solubility is a problem. “[Ingested] CBD has a very low bioavailability, something between 6 and 15 percent, which varies between people,” says Blessing. Because ingested CBD is so inefficient at actually getting to the brain to stimulate CB1 and other receptors, the doses shown to be effective have to be very high. “There’s no evidence that doses below 300 mg of CBD have any effect in any psychiatric measure,” says Blessing. “And in fact, dose-finding studies show that the lowest clinically effective dose of CBD for reducing anxiety is 300 mg.” Blessing is talking about induced anxiety in otherwise healthy patients, which is all we have studies on; studies of CBD’s efficacy in treating clinical anxiety, which would require regular doses, haven’t been published.
Derived from the stalk and seed of cannabis (hemp) plants, cannabidiol (CBD) oil or CBD hemp oil is a natural botanical concentrate that is high in the compound CBD. Of the more than 85 cannabinoids so far identified in the cannabis plant, CBD is the second most common after tetrahydrocannabinol (THC). Unlike THC, CBD is non-psychotropic and therefore doesn’t cause a euphoric high.
So is it possible that despite all this anecdotal evidence, low-dose CBD is a placebo? Sure, because, say it with me: We don’t know anything about CBD. “Unfortunately,” says Baron, “we are nowhere near close to having any definitive trials on effectiveness for most symptoms claimed to benefit from CBD with trials that are scientifically relevant, such as prospective randomized placebo-controlled trials.”
The final advantage in the above list of a lower cost per milligram is one worth looking into further. As previously mentioned, because a full spectrum product is derived from a whole plant ex-tract it typically costs more (you the consumer are getting more than just CBD). Chase Terwilliger, CEO of CBDistillery, adds, "It is less expensive to manufacture isolate-based products com-pared to full-spectrum products. Rather than taking advantage of a larger margin, we decided to pass the savings along to the consumers." For those looking for a pure CBD product, you will al-so be delighted to find that CBD oil made from isolate is typically less expensive than a full-spectrum product. Which brings up a final point which is to do your research on the industry standard pricing for cost per milligram to ensure you are not paying an unnecessary premium.
