There has been a fair amount of confusion surrounding the legality of CBD oil. But while the vast majority of cannabinoids are controlled substances under the Misuse of Drugs Act, rest assured that CBD oil is legal across the UK for medicinal purposes, provided it has been derived from an industrial hemp strain that is EU-approved. These strains contain very little to no THC (the psychoactive cannabinoid).
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.
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.
CBD is one of over 110 active cannabinoids inside marijuana plants and is most predominant inside the resin glands (trichomes) of the female cannabis plant. Your body contains cell receptors known as cannabinoid receptors. Cannabinoids, found in cannabis, are agonists that bind to these receptors. Cannabinoid receptors can be found all over the body including, but not limited to, the:
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.
Researchers at the Department of Pharmacognosy, The School of Pharmacy, University of London, UK, basis the study conducted on mice found that CBD oil has analgesic properties and may relieve chronic pain of all kinds . It can disrupt the activity of pain receptors in the body and instead cause a release of neurotransmitters such as serotonin and dopamine – “feel good” compounds that can ease discomfort and pain, even if the pharmaceutical painkillers have no effect.
Tetrahydrocannabinol is the most abundant cannabinoid in most medical and recreational marijuana strains. However, in hemp THC is a minor constituent and appears only in trace amounts under 0.3% by dry weight, as required by the U.S. government for hemp products. THC mimics the action of anandamide, a neurotransmitter naturally produced in the human body, and binds to CB1 receptors in the endocannabinoid system found mostly in the brain. The extremely low levels of THC in hemp make hemp oil non-psychoactive and safe for all ages to use.
‘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.’
That leaves those touting CBD’s effectiveness pointing primarily to research in mice and petri dishes. There, CBD (sometimes combined with small amounts of THC) has shown promise for helping pain, neurological conditions like anxiety and PTSD, and the immune system—and therefore potentially arthritis, diabetes, multiple sclerosis, cancer, and more.
