Over the last few months we’ve given you an overview of hemp, the endocannabinoid system (ECS) and the beneficial cannabinoids found in Cannabis sativa L. In last week’s post The Benefits of Cannabinoids there was one significant cannabinoid missing, cannabidiol (CBD). In this week’s post we will discuss the wildly popular cannabinoid cannabidiol (canna-bi-diahl) and help you begin to understand the distinctions between various CBD product forms.

Nowadays, CBD is everywhere and is constantly being talked about— and for good reason! With so many options, product types, and forms, it has become increasingly difficult to make an educated decision about which form of CBD to choose. One of the most important things to understand is how to determine the differences between CBD products. One topic we will discuss further, following the benefits of CBD, is how to understand the differences in forms of CBD, including full spectrum, broad spectrum, or isolate products.

As we shared in our earlier post Hemp vs. Marijuana, CBD was discovered in the 1940s and is one the most abundant cannabinoids in the hemp plant. It does not produce the psychotropic effects commonly associated with THC. When CBD was discovered, researchers recognized the potential of the plant, but due to legality reasons, which have unfortunately continued until very recently, and other obstacles it took over 20 years to begin really exploring and understanding how to best expand on some of the original findings. Throughout 1963-64, Dr.Raphael Mechoulam, an organic chemist at the Weizman Institute in Israel, and his team worked to identify the chemical structure of CBD, isolate it, and then synthetically recreate it in his lab. They found that, although CBD is one of the most abundant cannabinoids, it could be given at increased amounts with little to no side effects. It was Dr. Mechoulam and his team that first recognized that CBD had antiepileptic properties, research that would later be used to develop FDA approved pharmaceuticals; one for use in rare childhood seizure disorders. ^[1]

What is Cannabidiol (CBD)?

CBD is a phytocannabinoid found in various concentrations through most parts of the hemp plant, but the highest levels are found in the flowers and trichomes. Phytocannabinoids accumulate in the sticky cavity of trichomes, which are small hairs that largely occur in female flowers and can be found in lower concentrations in other aerial parts of the plant.^[2]

Benefits of CBD
In our last post titled The Benefits of Cannabinoids, we learned that CBD does not just start as CBD. It is created through a series of chemical conversions which occur in nature mostly through changes in temperature and time. This begins when Cannabigerolic acid (CBGa), the mother of cannabinoids, is broken down into its non-acidic form Cannabigerol (CBG), which then breaks down into Cannabidiolic acid (CBDa) and Tetrahydrocannabinolic acid (THCa). CBDa is then further broken down into CBD.

Interestingly it is estimated that by 2025 CBD will be close to a $25 billion-dollar industry.^[3] Clearly CBD has gained some incredible popularity with consumers, but we are also seeing an increase in research and clinical studies of the compound and are starting to discover new and exciting benefits. There is increasing evidence that CBD has numerous therapeutic potentials and is essential to supporting inner balance and the overall health and wellness of many of our body’s systems. If you read our previous posts on the ECS, you know that CBD binds to the network of receptors throughout the body that make up the ECS and play an important part in regulating pain perception, balanced emotions, and other autonomic functions. Several studies demonstrate the reduction of pain perception following intake of CBD,^[4] and when combined with other phytocannabinoids, it can cause an even greater reduction in pain perception. This research also supports the importance of the entourage effect to benefit health, using the synergistic effects of all the compounds found in hemp versus using isolated compounds.

What is not commonly known about CBD and its potential benefits is that, in 1999, the U.S. Government, under the Department of Health and Human Services, filed a patent on non-psychoactive cannabinoids, including CBD, as a treatment for specific illnesses. The U.S. Government was awarded that patent in 2003; “Cannabinoids as antioxidants and neuroprotectants, Unites States Patent 6,630,507”. Click here to see the full patent.

As popularity has grown over this compound both medical and regulatory agencies have begun to weigh-in with their opinions about the benefits and safety profiles of CBD. For example, the World Health Organization (WHO) published their Cannabidiol (CBD) Critical Review Report^[5] where the WHO discussed the available research in regard to medical and recreational uses, safety profiles, and outcomes following CBD usage. Following this report, the WHO recommended that pure CBD and CBD preparations containing no more than 0.2% THC should no longer be included in the international drug control conventions, after noting in their report that CBD had been found to be “generally well tolerated with a good safety profile”.

Interestingly, in addition to the WHO’s recommendation to remove CBD from international drug control conventions, the World Anti-Doping Agency (WADA), an international organization that “was founded with the aim of bringing consistency to anti-doping policies and regulations within sport organizations and governments right across the world”^[6], removed CBD from their list of prohibited substances. However, it is important to note that although CBD is no longer prohibited, athletes should be aware that many CBD products contain low levels of THC, which is still a prohibited substance under WADA.

Product Formulation of CBD
For the majority of CBD supplements on the market it appears the products are mostly sold in three different overarching forms, or categories—full spectrum extract, broad spectrum extract, and isolate, but what is the difference?
The following definitions of these products have come from the U.S. Hemp Authority Glossary, developed to promote standardized labeling for the hemp industry.

Full Spectrum Extract “is hemp extract including THC and other cannabinoids, terpenes, and other naturally occurring compounds, that has been processed without intentional complete removal of any compounds and has a final THC quantification of not greater than 0.3%.”
Broad Spectrum Extract “is hemp extract that has been intentionally processed to remove THC such that the quantified THC has been deemed non-detectable by a compliant laboratory using a fit-for-purpose method with a limit of quantification of less than 0.01%.”
Isolate “is the confined molecule and most pure form of the cannabinoid such as CBD.”

Ultimately, the difference between a full spectrum, broad spectrum, and isolate products seems to come down to efficacy; the degree of product processing; and number of compounds in the final product. The most important thing you can do as a consumer is to first research the different forms and then choose a product to best fit your needs and desired outcomes.

Because each form of CBD is specific to a consumer’s need, the conversation around full spectrum versus broad spectrum versus isolate CBD is a much bigger one. We will go into more detail about the specific differences about each of these forms of CBD and how they contribute to the entourage effect in a future post.

After such invaluable insight into the U.S. hemp regulations and the 2018 Farm Bill by our very own Joy Beckerman, we return to science in this week’s post. Let’s take a look at some of the different cannabinoids that are found in Cannabis sativa L. and what benefits research on these cannabinoids has revealed.

Now that we are more familiar with the endocannabinoid system, let’s focus on some of the compounds that activate this system and, as of late, have gained a lot of attention—cannabinoids. Becoming familiar with some of the more abundant cannabinoids found in the hemp plant, and the research that has been conducted to further analyze these compounds may help us better understand the effects cannabinoids can have on our systems.

As we have discussed in previous posts, phytocannabinoids are cannabinoids that have been produced in a plant. In this case we are discussing the hemp plant, which as defined by federal regulation cannot contain greater than 0.3% tetrahydrocannabinol (tetra-hydro-cannab-in-al), referred to as THC. THC is just one of over 100 phytocannabinoids¹researchers have discovered within this plant.

“Mother of Cannabinoids”

The highest percentage of phytocannabinoids are found in the unseeded flower buds of female plants.²

The most abundant of the phytocannabinoids begin as “parent” cannabinoids called Cannabigerolic (canna-bi-ger-o-lic) acid or CBGa, also known as the “mother of cannabinoids,” and Cannabigerovarinic acid or CBGVa. The formation of some of the most abundant cannabinoids occurs when CBGa is converted into:

Cannabigerol (canna-bi-ger-al), commonly called CBG;
Cannabidiolic (canna-bi-di-ah-lic) acid—CBDa;
Tetrahydrocannabinolic (tetra-hydro-cannabin-alic) acid—THCa; and
Cannabichromenic (cannabi-chrom-ee-nic) acid—CBCa.

As further break down of these compounds occur other cannabinoids are revealed. In the image below, the parent cannabinoids CBGa and CBGVa, are converted to other compounds.

These chemical conversions typically occur in nature mostly through changes in temperature and time. In the laboratory or manufacturing facility however, these conversions can be achieved in an expedited fashion through a multitude of manufacturing processes such as time, temperature, and pressure. One common example of this process—called decarboxylation (de-carboxil-ation)—involves exposing the plant, or an extract from the plant, to high temperatures over an extended period of time. In a fresh hemp flower or a fresh extract, CBDa exists at a very high level, which can be converted to CBD through the process of decarboxylation, in order to produce products formulated with consistent levels of CBD.

Cannabinoid Benefits

Although discussed less often than CBD, CBG is an important cannabinoid, and like CBD, has been shown to be non-psychotropic (mind-altering).³ In a recent study, CBG was shown to have some aseptic-like properties and activity, and appeared to support the destruction of “drug-resistant MRSA by destroying preformed biofilms and resistant organisms in cell culture and non-human studies.”⁴CBG has also been studied as a possible way to support healthy levels of inflammatory compounds and support normal bone growth and healing.⁵

The acidified compounds of THC and CBD, Tetrahydrocannabinolic acid (THCa) and Cannabidiolic acid (CBDa) are believed to have their own supporting attributes. Like CBG, both THCa and CBDa are non-psychotropic, as they do not produce intoxicating effects. THCa has been researched as a possible way to support healthy cell function and healthy muscle function while CBDa and THCa also have been studied as a way to help support appropriate levels of inflammatory-compounds.⁶ Additionally, in one study, CBDa was correlated with increased serotonin receptor level activation, a receptor associated with the serotonin neurotransmitter, known for its participation in overall well being, emotional balance, and other autonomic system-related functions.⁷

THC, primarily recognized for its psychotropic effects, is used in both medicinal and adult-use forms across the world. The Food and Drug Administration (FDA) has approved three drugs, Marinol^®, Cesamet^®, and Syndros^®, as synthetic versions of THC for therapeutic uses in the United States. As of June 2020, in the U.S., there are over 10 states with adult use regulations and over 30 states with regulations regarding medical use of THC.

CBC, like CBD and CBG, is non-psychotropic, and interestingly, is thought to work through non-cannabinoid receptors that can communicate with the endocannabinoid system (ECS) to help balance emotional fluctuations, support healthy bone growth and support healthy cell function.⁸ Although CBC is structurally similar to THC and CBD, it has been shown to affect the production of our endocannabinoids, leading to an increase in the level of Anandamide. CBC binding appears to take place on capsaicin receptors, called TRPV1, which are responsible for nociception, heat sensation, body temperature, and detection of harmful toxins we ingest or absorb from our external environment.⁹ CBC also binds to sensory receptors, called TRPA1, that stimulate our senses and protective responses¹⁰. Interestingly, studies of CBC use on the skin have shown its support of overall skin health and has shown its ability to maintain normal oil levels.¹¹

Future Cannabinoid Potential

As the science evolves over time, and the variations in the hemp plant continue to change through breeding techniques and genetic research, we will see the potential of many more cannabinoids like Tetrahydryocannabivarin (THCV) and Cannabidivarin (CBDV), which have already begun to show therapeutic potential across multiple body systems. Studies have demonstrated the potential of THCV to support emotional balance, support healthy appetite level and also supports healthy bone growth as studies revealed it binds with both CB1 and CB2 receptors throughout our ECS. ¹² Likewise, CBDV has shown promise in supporting healthy brain development and healthy cellular function by binding with the non-cannabinoid receptor, TRPV1,¹³ previously mentioned as a binding site for CBC. In addition, a few companies have started looking into cultivation of pharma grade, algae-based cannabinoids for medical therapies. With the potentially massive grow ability, algae-based cannabinoids could eliminate the need for synthetic cannabinoids.¹⁴ As many believe the 2018 Farm Bill was passed to create a new stream of income for U.S. farmers, synthetic cannabis and non-hemp derived cannabinoids may become obsolete (i.e. under the guidelines of the U.S. Hemp Authority Certification, synthetic cannabinoids and non-hemp derived cannabinoids are not allowed). We will discuss the ins and outs of the U.S. Hemp Authority in a future post.

For the continued benefit to our bodies and in order to support inner balance, it is important for us to learn more about cannabinoids and to support the research being conducted on these compounds. Although this post discussed the benefits of major cannabinoids in the hemp plant, we did not discuss the most popular one—CBD. Never fear! We didn’t forget it. This cannabinoid is so important, it deserves its own post. In our next post we will take an in-depth look at CBD and the benefits that have been uncovered by past and current research.
