Scott Shannon, M.D., assistant clinical professor at the University of Colorado, recently sifted through patient charts from his four-doctor practice to document CBD’s effects on anxiety. His study, as yet unpublished, found “a fairly rapid decrease in anxiety scores that appears to persist for months,” he says. But he says he can’t discount a placebo effect, especially since “there’s a lot of hype right now.”
There’s no definite amount that’s appropriate for everyone, but the ratio of CBD to THC will indicate how psychoactive the product is and if it’s legal in your state. The more CBD compared with THC, the less of a high, and vice versa. “Managing psychoactivity is key to successful cannabis therapy,” says Lee. “Amounts should be made clear on the label and lab-certified so people know what’s helping them and what’s not.”
To extract, you soak the hemp plant in a solvent, such as grain alcohol. After the material soaks, the remaining liquid contains CBD and the other cannabinoids from the pant. Once you evaporate the solvent, the CBD hemp oil remains. The oil is then ready to either consume or add to edible products. Commercial producers have adopted and modified Mr. Simpson’s method. CBD hemp oil producers use ethanol to extract CBD.
Basically, cannabis is an umbrella term that includes both hemp and marijuana plants. Cannabis sativa is actually the scientific name of the cannabis plant (Cannabis = genus; sativa = species), and hemp and marijuana are just two different “varieties” of it (i.e. you could refer to both marijuana and hemp plants as “cannabis” plants, but you would not, for instance, refer to a “marijuana” plant as a “hemp” plant). Hopefully that’s not too confusing.
When looking at isolate, it is important to verify the purity. While many are in the 99.9+% range with no identifiable amounts of THC, there are lower purity ones (such as 99.5% or lower) that may still have trace amounts that show up on the labs. This small amount is typically negligible, and is nowhere near the amount usually found in full spectrum products. But it’s still something to be aware of for those seeking the purest they can find.
Our bodies are thought to produce endocannabinoids by the billions every day. “We always thought the ‘runner’s high’ was due to the release of dopamine and endorphins. But now we know the euphoria is also from an endocannabinoid called anandamide,” its name derived from the Sanskrit word for bliss, says Joseph Maroon, M.D., clinical professor and vice chairman of neurosurgery at the University of Pittsburgh Medical Center. We produce these natural chemicals all day, but they fade quickly because enzymes pop up to destroy them. That’s where CBD comes in: By blocking these enzymes, CBD allows the beneficial compounds to linger. This is why Amanda Oliver, 31, a career consultant in Charleston, SC, pops a CBD gummy bear each night before bed. “I used to lie there tossing and turning as my mind raced from work projects to whether I had set the home alarm,” Oliver says. One piece of candy with 15 mg of CBD is enough to shut off her brain and facilitate sleep. She also swears by the CBD oil she takes at the height of her period, which she says quells her debilitating cramps.
Cohen has found that chronic conditions including autoimmune diseases and pain syndromes can be helped with a 6-mg under-the-tongue tincture (the fastest delivery system) or a 25-mg capsule taken twice a day. Dosages for topical products like lotions are especially hard to determine—there’s no clarity on how much CBD gets into the system through the skin.
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.
While there is much debate on which form is better, this 2015 study leans in favor of full spectrum CBD oil products. There are many that believe that other cannabinoids, THC especially, are necessary to take full advantage of what cannabis has to offer. Ultimately, however, we are all different and it comes down to the individual user and their needs. If drug testing is a concern, you’re encouraged to seek out CBD isolate products (or terpsolates) or broad spectrum products instead of full spectrum.
A study published by David Cheng, Postdoctoral Scientist, Neuroscience Research, University of New South Wales, NSW, Australia, says that CBD has a potential as a preventive measure against symptoms of Alzheimer’s. This presents yet another exciting development for medical researchers, given the persistent challenges to finding effective solutions for this condition.
Industrial production of CBD oil is done by combining the cannabinoid rich plant with other compounds like CO², butane, ethanol or olive oil etc., all of which leave their residues in the final product. The most important part of CBD oil extraction is selection of right plant for the extraction of oil. Cost of final product will depend on its potency and purity which is controllable only via oil extraction technique.
‘In doses used as a food supplement, CBD poses few risks, and side effects are unusual but can include a dry mouth or drowsiness,’ reveals Dr Brewer. ‘Higher doses used medically are well tolerated, and there are no serious safety concerns. A World Health Organization report issued in 2017 concluded that cannabidiol does not appear to have abuse potential or cause harm.'
‘CBD has proven anti-anxiety effects and may be helpful in depression, based on anecdotal reports,’ says Dr Gordon. ‘I use high CBD prescription cannabis medicine products as part of a mental health protocol with my patients suffering with anxiety and depression. The antidepressant effects of CBD have been shown in animal models, but we now need large, depression-specific studies in humans as the next step.’
The Internet is lousy with the stuff, but for a safe and reliable source, talk to your physician, advises McLaughlin. She may be able to introduce you to a reputable practitioner who can offer CBD oils and related therapies—or she may know of a colleague who can make a referral. If you’re trying to treat a medical condition, it’s better to avoid the guesswork and find guidance from a practitioner who’s had experience in—and is knowledgeable about—the most reliable CBD products and doses for your condition. Here are 14 things you should never lie to your doctor about.
As a vitamin supplement. Hemp oil, in particular, holds high doses of important vitamins, like Vitamins E, B, B1 and B2. Hemp oil is also an invaluable source of protein and antioxidants, and contains high levels of helpful body supplements like potassium, magnesium and fatty acids. (which can also help cure maladies like acne and psoriasis, and is known to improve the human body's cholesterol levels.
There are more than 80 cannabinoids found in cannabis plants, with THC being the primary one, followed by CBD. However, in the hemp plant, which is a different strain of the species Cannabis sativa, CBD is the main active ingredient, and THC is barely present, making its use and legality more widespread. The reason that CBD is such an effective form of support for human health is due to the body’s endogenous cannabinoid system. This regulatory structure of the body has millions of cannabinoid receptors in the brain and nervous system, which react not only to plant-derived cannabinoids (such as hemp and marijuana) but also to natural cannabinoids produced within our body. When hemp oil is used and processed by the body, it is effectively boosting the function of the endocannabinoid system, helping our body regulate itself in many different ways.
