Although CBD oils aren’t regulated by the FDA, purchasing products stateside from one of the nine states where recreational and medical cannabis use is legal will likely result in a higher-quality product than buying one made with hemp-derived CBD oil imported from abroad, says Martin Lee, director of Project CBD, a nonprofit that promotes medical research into CBD.
Because of recent legislation legalizing marijuana, CBD product sales have grown. People are more open to the medical benefits of the drug, especially now that CBD can be separated from THC. With popularity and interest on the rise, manufacturers have expanded their product offerings. Products typically come in two types: nutritional or medicinal products and beauty products.
Given CBD’s reputation as a popular, artisanal remedy, one would think that Epidiolex would command a lot of “off label” attention. After all, physicians often prescribe pharmaceuticals off label to treat conditions that were not the actual focus of clinical trials. But the costly price tag for Epidiolex (more than $30,000 annually) precludes off label prescribing as well as affordable access for tens of millions of Americans without health insurance.
Keep in mind, too, that CBD product companies use different CBD sources, extraction methods and production techniques – and not all resulting products are created equal. You'll have to do your own research to determine which companies you're willing to trust, Asquith says. Plus, how the products are packaged and consumed – be they in oils, creams or capsules – affect how they're absorbed in the body. Edibles, for example, are well-absorbed, while oils taken under the tongue are "baloney," Tishler says. And of course, salespeople at herb shops don't have the same mission, knowledge, training or oversight as physicians and pharmacists. "We have spent the last 100 years or so developing the pharmaceutical system because it works," Tishler says.
From anecdotal evidence in humans and from animal studies, CBD appears to affect the way we experience pain, inflammation, and anxiety. “Scientists have identified a number of receptors in the nervous system where CBD acts,” says Orrin Devinsky, MD, professor of neurology, neurosurgery, and psychiatry at NYU Langone. “It’s established that CBD has anti-inflammatory properties and can increase activity at some serotonin [the feel-good neurotransmitter] receptors.”
Now that cultivation of hemp has become legal in some parts of the world there are widespread discussions about how the medicinal properties of CBD oil is curing people of varied illnesses. Since it is derived from hemp which is a strain of cannabis, people had apprehensions about this product but now with widespread media coverage usage has become common in therapy clinics. CBD is one of the many cannabidiols that exist naturally in the Cannabis plant along with THC.There is difference between plants rich in CBD and those rich in THC as the former is called indica-dominant plants while latter is sativas rich plant. While sativas rich plants give an uplifting feeling, the indica rich plants give the body a relaxed feeling that is ideal for people in acute pain.
In response to the FDA’s historic decision, the Drug Enforcement Administration (DEA) announced in September 2018 that it had removed Epidiolex from Schedule I classification, a category reserved for dangerous drugs with no medical value. Henceforth, Epidiolex would be considered a Schedule V drug, the least dangerous designation under the Controlled Substances Act.
Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.
Because the FDA considers CO2 extraction to be GRAS or “generally regarded as safe” for commercial extraction, this method is popular in the food industry. The stability of supercritical CO2 also allows most compounds to be extracted with little damage. In the coffee industry, supercritical CO2 is already widely accepted as safer than traditional solvents to extract the caffeine from decaffeinated coffee beans.
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.
‘The media has no doubt helped drive this popularity,’ says Dr Sarah Brewer, medical director at Healthspan. ‘However, the main drive is because people who take it experience the benefits very quickly, and “word of mouth” is a powerful thing. CBD oil also has such a wide range of benefits, reducing anxiety, promoting relaxation, ensuring a good night’s sleep, reducing pain perception and improving general feelings of wellbeing. It therefore appeals to a wide range of people.’
In other words, many popular claims remain unfounded – and overlook the fact that there's a difference between CBD that's studied in labs for particular conditions and CBD products that are sold to consumers for general well-being. "What happens is people say, 'Look, CBD is harmless and it doesn't get me intoxicated, so I'm going to take it for what ails me," says Dr. Jordan Tishler, a Harvard physician and CEO of InhaleMD, a Boston-area practice specializing in cannabis therapeutics. "Then they're going to get some perceived benefit because that's the way the placebo effect works, and then they go and trumpet this."
At least one benefit of CBD is well-supported by science: It can be effective in treating children with rare, genetic seizure disorders. Adults, children and even animals with epilepsy have been shown to benefit from the chemical too, the World Health Organization reports. There's also some evidence that CBD can help with anxiety, says Dr. Robert Carson, an assistant professor of neurology and pediatrics at Vanderbilt University who focuses on children with epilepsy. "In children, especially those with autism spectrum disorders, this may manifest as improved interactions with others," he says. Other preliminary research shows CBD holds promise for conditions including Alzheimer's disease, cancer, psychosis and Parkinson's disease – and is pretty much impossible to abuse or become addicted to, WHO says.
CBD has proven neuroprotective effects and its anti-cancer properties are being investigated at several academic research centers in the United States and elsewhere. A 2010 brain cancer study by California scientists found that CBD “enhances the inhibitory effects of THC on human glioblastoma cell proliferation and survival.” This means that CBD makes THC even more potent as an anticancer substance. Also in 2010, German researchers reported that CBD stimulates neurogenesis, the growth of new brain cells, in adult mammals.
That being said, though, CBD isolate still has a very relevant place in the cannabis market. A lot of people, for instance, use it to concoct their own personal daily CBD remedies – they mix the pure powder with oil, or they add it into their coffee, or they make edibles out of it. Since it comes in an easily-measurable powder, it’s a great option for those individuals who are trying to calculate exact personal dosages of CBD medication by the milligram.
Full spectrum CBD also contains a variety of essential vitamins, minerals, fatty acids, protein, chlorophyll, terpenes, flavonoids, and fiber. When referring to CBD in the hemp plant, it’s important to understand that hemp contains a large number of cannabinoids (in trace amounts), but the main compound is cannabidiolic acid (CBDa). As CBDa is more abundant in the hemp plant, firms must decarboxylate the oil. This process heats the oil and changes CBDa into CBD.
With that being said, let’s discuss the wonderful thing we call CBD oil. CBD, cannabidiol, is one of over 85 active cannabinoids identified in hemp and other cannabis plants. CBD oil is derived from hemp, due to its abundance naturally occurring in the plant. CBD oil is extracted using the whole plant, stalks or flowers. Since hemp contains only trace amounts of THC, CBD oil products are non-intoxicating.
CBD Isolate is the purest supplement available. It’s a 99% pure CBD supplement derived from hemp oil. Despite its concentration, CBD isolate effects are similar to other CBD concentrates, and it can be used in a variety of ways. It can be consumed itself, added to foods and beverages, or vaporized. You can also add it to other CBD products to increase their potency.
