Because of this classification, it's not easy for researchers to get their hands on the drug. "That's not to say you can't do it, but there are hoops you need to jump through that can be a pain, which may deter researchers from going into this space," Bonn-Miller said. "Relatively speaking, it's a small group of people in the U.S. that do research on cannabinoids in humans."
In most countries it is forbidden to create oil from cannabis, because cannabis is a controlled substance (i.e. illegal drug). However, CBD, unlike THC, is not a controlled drug, and regulations are minimal by comparison in many places around the world. This has led to the appearance of numerous CBD-rich extracts on the international market. Most of these extracts contain low levels of CBD and high levels of CBD-acid, the natural constituent of the fresh cannabis plant before it is heated.
Well, primarily because it’s just simpler to get. Because it’s legal, it can be ordered right online without a rpescription. Second, many people prefer the natural aspect of CBD oil found in hemp, which doesn’t need to be coaxed or altered in order to derive high levels of CBD from it. CBD oil from hemp is pure, which means the levels of THC and other trace compounds are miniscule. That means you can count on getting the effects of CBD without experiencing unwanted side effects. And finally, because hemp-derived CBD oil has been used for so long medicinally, many people trust it more than CBD oil from hybridized pot strains, which have only recently begun to be explored as a medicinal product.
In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
