The U.S. Department of Health & Human Services suggests that consumers should prioritize eating a variety of nutritious foods over taking dietary supplements. No dietary supplement should take the place of a healthful diet. That being said, the agency does allow that some supplements can help support overall health and provide people with the nutrients they need. For instance, vitamin D and calcium help strengthen bones and omega-3 fatty acids may help some who have heart disease.
Cannabis sativa L. has been selectively bred for recreational uses to obtain the maximum “high”, so the level of delta-9-tetrahydrocannabinol (THC) have been increased very much (up to 20-25%) and, in upping the potency through selective breeding, CBD has been selectively eliminated from recreational varieties or, eventually, it is rarely found in specific varieties. CBD is often found in hemp – in varieties used to produce fiber and seeds. But the combination of CBD/THC in cannabis seem to be beneficial for medical use.
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?
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?
