Cannabidiol (CBD) is a naturally-occurring constituent of industrial hemp (cannabis sativa) plants. It is the most abundant non-psychoactive cannabinoid found in cannabis and is being scientifically investigated for numerous reasons. Most people have heard of a cannabinoid called THC, which is the ingredient in cannabis that gets users high. Unlike THC, CBD (cannabidiol) is a non-psychoactive cannabinoid and does not cause a high.
California’s legalization spurred Dr. Geoffrey Guy and Dr. Brian Whittle to found GW Pharmaceuticals, a company that would utilize clinical trials to unpack various cannabinoid formulations as potential therapies with the overriding focus of developing what would later be known as Sativex (Nabiximols). This oral mucosal spray was made up of CBD and THC in a 1:1 ratio and successfully combated neuropathic pain, spasticity, overactive bladder, and symptoms of multiple sclerosis.

In 2014, the Kentucky legislature revised the definition of marijuana under state law to create legal protection for patients who use a cannabidiol (CBD) medicine as part of an approved clinical trial or on the written order of “a physician practicing at a hospital or associated clinic affiliated with a Kentucky public university having a college or school of medicine.”
Given the opioid crisis, physicians are less likely to lead with narcotics, and some of us are deciding not to prescribe them altogether. The problem with narcotics is that they work. They work really well. Sometimes too well, leading to a patient becoming so comfortable they “forget” to breathe. So, while reducing the amount of narcotics prescribed to patients is a good thing, the problem is physicians don’t have a lot of good alternatives to recommend to their patients, until now.
Even as the research proceeds, thousands of people are using CBD as medicine. A British pharmaceutical company, GW Pharma, has developed two CBD drugs: Sativex, which contains a 1-to-1 ratio of CBD and THC, and Epidiolex, which is pure CBD. The former is prescribed for the painful muscle spasms that occur in multiple sclerosis, while the latter is aimed at childhood seizures. Sativex is not available in the United States, but it is approved in 29 other countries, including Canada, England and Israel.
The list includes marijuana (undifferentiated by strain) and heroin. (While the federal government oversees marijuana research, marijuana use is regulated, in part, by state laws.) As a result, scientists who study the compound must follow a host of restrictive rules. Last year, responding to a request from several governors to change marijuana’s designation, the Drug Enforcement Administration announced that all cannabis would remain a Schedule 1 drug.
Researchers in New Zealand have studied whether cannabis can be used to treat severe motor and vocal tics in those suffering from Tourette syndrome. The study concluded that subjects who took a controlled THC-CBD medicated spray showed marked improvement in the frequency and severity of motor and vocal tics post-treatment. Although the study is only a small clinical trial, it is one of the first to specifically analyze the effects of cannabis on Tourette syndrome.
Ananda Hemp is a tempting brand to say the least. They source their seeds from the largest hemp seed bank in the United States and have generational farmers grow their products. Plus, they offer excellent customer service with their products. However, I was disappointed that they had only two concentrations of tinctures available, one amounting to 200 mg and other being 600 mg.

Now, with the passing of the new 2018 Farm Bill, hemp and hemp-derived products have been officially removed from the purview of the Controlled Substances Act, such that they are no longer subject to Schedule I status. Meaning that so long as CBD is extracted from hemp and completely pure (without any THC — something the DEA doubts is possible) and grown by licensed farmers in accordance with state and federal regulations, it is legal as a hemp product.

We use a combination of both Subcritical and Supercritical extractions. This allows us to perform a “fractional extraction” by first extracting at lower pressures to remove the lighter, temperature-sensitive volatile oils, and then subsequently extracting the same material at a higher pressure to remove the remaining oils. This approach is the best because it allows us to extract a complete range of cannabinoids, terpenes, essential oils, and other beneficial phytochemicals that yield a more potent blend.
With President Trump signing off on the Agricultural Improvement Act of 2018 (aka the 2018 Farm Bill) last month, the federal government now fully recognizes hemp as a legal agricultural product. But while many reports are claiming that this means that cannabidiol (CBD) is also legal, that’s not quite correct. With a lot of misinformation flying around, and contradictions between state and federal laws, things are admittedly somewhat confusing. Let’s try to sort things out by answering some questions about hemp, CBD, and what has recently changed in federal law.
CBD was first discovered in 1940 by Roger Adams, a prominent organic chemist at the University of Illinois. Shortly thereafter, other scientists began testing isolated cannabinoids on lab animals; notably, Walter S. Loewe ran trials on mice and rabbits with the cannabinoids THC, CBD and CBN. He found that CBD produced no observable effects in the animals’ behavior while THC caused, what he called, a “central excitant action” in rabbits. Despite science’s movement forward, scientists were completely unaware of the cannabinoids’ chemical structure, so no one could tell which specific compound resulted in which effect.

CBD, short for cannabidiol, is a compound found in cannabis that has gained prominence in recent years for its therapeutic properties. Cannabis advocates have hailed the cannabinoid for its promise in combating seizures, anxiety and myriad other ailments. CBD is "the new ‘it’ drug," according to The Washington Post. It’s a "rapidly rising star for its capacity to deliver mental and physical benefits," according to Quartz.
The FDA’s refusal to allow companies to market CBD as a dietary supplement is based on the fact that federal classification as a dietary supplement requires that a substance has not been authorized for investigation as a new drug or medicine. Since Epidiolex has been studied in clinical trials by GW Pharmaceuticals going back several years now and was granted orphan drug status by the FDA in 2013, CBD cannot therefore be classified as a dietary supplement. Or so the FDA says. But cannabis companies are arguing that they started marketing CBD as a dietary supplement before there were any drug trials involving CBD, such that they should still be allowed to claim dietary supplement status for their products. Thus far however, the FDA isn’t budging on this issue.
Cannabis most likely originates from Central Asia, as archeological evidence indicates that it was already cultivated in China for food and fiber 10 000 years ago. Even in ancient Egyptian mummies, clues have been found for the use of Cannabis as food or medicine.25 In fact, Cannabis is one of the oldest known medicinal plants and is described in almost every ancient handbook on plant medicine, most commonly in the form of a tincture or a tea.26,27 Some religions were closely related with the properties of the Cannabis plant. For example, in Hindu legend, Cannabis is believed to be the favorite food of the god Shiva, because of its energizing properties. As Cannabis spread from Asia toward the West, almost every culture came into contact with this miracle plant. Nowadays, varieties of Cannabis can be found in all temperate and tropical zones, except in humid, tropical rain forests.28
‘A good pointer of quality is that the manufacturer will be a member of the Cannabis Trades Association UK, an organisation created to ensure legal and ethical CBD trading standards, says Dr Brewer. ‘Only companies that meet high quality standards can carry its seal of approval such as Healthspan’s range of CBD Oil products, for whom I act as Medical Director.’

But he wasn’t finished. In February of 1980, Dr. Mechoulam teamed up with South American researchers to publish a study regarding cannabis and epilepsy. This study is seen as one of the earliest double-blind studies of CBD on clinical subjects. The study Dr. Mechoulam and his team conducted included 16 people, many of whom were children, who all suffered from severe epilepsy. The results were startling: Every subject who received CBD experienced improvement in their condition with little to no side effects. This anticonvulsant study has since proven to be an integral milestone in the world of clinical marijuana research, but largely went unnoticed at the time.
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.
