What Are Hemp Cannabinoids?
Cannabinoids and the Cannabis Sativa Plant
The cannabis sativa plant is a remarkable botanical species that contains over 100 distinct phytocannabinoids, which are natural chemical compounds responsible for many of its therapeutic and psychoactive effects. Notably, cannabis sativa and hemp plants are widely recognized for their high THC content and high CBD content.
Among these, certain cannabinoids like Delta 9 THC and cannabidiol (CBD) are the most widely recognized, often stealing the spotlight due to their higher concentrations and well-documented effects. Other plants contain structures very similar to cannabis or marijuana, but cannabis is the only natural source of THC, CBD, etc.
Delta 9 THC is best known for its psychoactive properties, which produce the “high” associated with cannabis use, while CBD has gained attention for its non-intoxicating therapeutic potential in areas such as anxiety relief, chronic and cancer pain management, and inflammation reduction.
For instance, research found in 15 RCTs (randomized clinical trials) discovered that using cannabinoids such as THC reduced pain by 30% when compared to control groups. Animal studies also suggest CBD may help with anxiety and lessen cravings for substances such as alcohol and opioids.
Lesser Cannabinoids – Their Legality and Applications
However, beyond these well-known cannabinoids, industrial hemp — legally defined by the 2018 U.S. Farm Bill as cannabis sativa containing no more than 0.3% Delta 9 THC by dry weight — has brought increased attention to its lesser-known cannabinoids.
These so-called “minor” cannabinoids include compounds like tetrahydrocannabivarin (THCV) and cannabigerol (CBG), which are now being celebrated for their unique benefits and potential applications.
THCV, for instance, has been studied for its possible appetite-suppressing effects (similar to some dietary supplements), while CBG shows promise in areas like anti-inflammatory and neuroprotective therapies.
Notably, many of these cannabinoids originate from one key compound in the plant: cannabigerolic acid (CBGA), often referred to as the “mother cannabinoid.” CBGA is the foundational molecule from which other cannabinoids are synthesized. Through enzymatic processes, CBGA transforms into precursor compounds such as tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA).
These precursor acids, when exposed to heat or light, undergo decarboxylation, converting into the more familiar cannabinoids like Delta 9 THC and CBD, unlocking their full effects in the body.
The Endocannabinoid System (ECS)
Cannabinoids produce their effects on the human body by interacting with a complex cell-signaling system known as the endocannabinoid system (ECS).
The ECS is a regulatory network that plays a critical role in maintaining balance, or homeostasis, in the body. It is involved in various physiological functions, including pain regulation, mood stabilization, appetite control, immune response, and even sleep cycles.
Cannabinoid Receptors
The system is composed primarily of two types of receptors: CB1 and CB2 cannabinoid receptors, which are distributed throughout the body. CB1 receptors are found predominantly in the brain and central nervous system, while CB2 receptors are more concentrated in the peripheral organs and immune cells.
Delta 9 Effects on Cannabinoid Receptors
Delta 9 THC, for instance, binds strongly to CB1 receptors in the brain, which is why it produces psychoactive effects such as altered perception and euphoria. The runner’s high, a euphoric feeling experienced during aerobic exercise, has long been linked to endorphin release. However, newer research indicates it may actually be caused by endocannabinoids instead.
CBD Effects on Cannabinoid Receptors
On the other hand, cannabinoids like CBD do not directly bind to these receptors but instead influence them indirectly, modifying the way the ECS responds to other compounds. Minor cannabinoids like THCV offer even more intriguing possibilities.
Unlike Delta 9 THC, THCV can act as a CB1 receptor antagonist, potentially suppressing appetite and offering an alternative for those looking to manage weight.
Similarly, CBG interacts with both CB1 and CB2 cannabinoid receptors. Research suggests that it may have anti-inflammatory and neuroprotective properties, making it a focus of interest for treating conditions such as glaucoma and neurodegenerative diseases.
The interactions between cannabinoids and the ECS illustrate the remarkable versatility of these compounds. Despite sharing common biosynthetic origins, cannabinoids can produce a wide range of effects depending on how they engage with ECS receptors.
These nuanced interactions are why the therapeutic potential of cannabinoids continues to inspire significant interest in both research and medicine.
As we learn more about minor cannabinoids and their individual properties, their medicinal role in health and wellness is likely to expand, offering new possibilities for targeted therapies and personalized treatment options.
Debunking Common Myths About Hemp Cannabinoids
MYTH 1: THCA Is Just Another Form of “Diet Weed”
What THCA Is and How It Works
Tetrahydrocannabinolic acid, or THCA, dominates raw cannabis plants but has no psychoactive effects on its own. The presence of a carboxylic acid group prevents THCA from binding effectively to CB1 receptors.
However, once exposed to heat, THCA undergoes a process called decarboxylation, transforming into Delta 9 THC, the familiar psychoactive compound. This means that consuming raw cannabis products with high THCA levels will not create the “high” associated with decarboxylated Delta 9 THC.
Therapeutic Benefits of THCA
Instead of psychoactive effects, THCA offers unique therapeutic benefits. For example, emerging research shows that THCA may help reduce inflammation and nausea.
Despite the promising findings, human clinical trials remain scarce. Medical cannabis advocates stress the need for robust research before THCA-based treatments can be standardized.
MYTH 2: Delta 8 THC and Delta 9 THC Are Essentially the Same
The Science Behind Delta 8 vs. Delta 9 THC
Both Delta 8 THC and Delta 9 THC are natural cannabinoids in hemp, but their chemical structures differ slightly. Delta 8 has a double bond on its eighth carbon chain, whereas Delta 9’s double bond sits on the ninth.
This seemingly small distinction creates significant changes in how the two interact with CB1 receptors in the ECS. While both compounds produce psychoactive effects, Delta 8 binds less strongly to CB1 receptors, resulting in milder effects.
A 2023 Forbes Health survey highlighted how Delta 8 users often report less anxiety compared to those consuming Delta 9. However, comparing their effects can be tricky since product purity and concentrations vary widely in the market.
Legal and Safety Considerations
Delta 8 THC occupies a legal gray area under the 2018 Farm Bill due to its synthetic production. It is predominantly created by chemically altering CBD through enzymatic conversion or chemical synthesis. The process can result in contamination from harmful byproducts like residual solvents or acids.
While Delta 9 THC remains a federally controlled substance unless its concentration in hemp is under 0.3%, 12 U.S. states have banned Delta 8 specifically because of safety concerns and its synthetic nature.
MYTH 3: THCV Solely Acts as “Diet Weed”
More Than Appetite Suppression
Often dubbed the “diet weed,” tetrahydrocannabivarin (THCV) is a cannabinoid known for its appetite-suppressing properties. Acting as a CB1 antagonist at higher doses, THCV may reduce food cravings and calorie intake. A 2021 study showed that 61% of participants consuming THCV products experienced a reduction in hunger.
At smaller doses, however, THCV may paradoxically activate CB1 receptors, temporarily stimulating appetite rather than curbing it.
Neurological and Metabolic Potential
Beyond weight management, preliminary research suggests THCV could improve motor coordination and tremor control in patients with neurodegenerative conditions.
For instance, a British Journal of Pharmacology study found that THCV’s neuroprotective effects may alleviate symptoms of Parkinson’s disease in rats. Larger-scale clinical trials are still required to confirm safety and efficacy in humans.
MYTH 4: THCP Is 33 Times More Potent Than THC
Clarifying THCP’s Potency
First discovered in 2019, tetrahydrocannabiphorol (THCP) captured attention due to its seven-carbon side chain, which grants it up to 33 times greater CB1 receptor affinity compared to Delta 9 THC in lab models.
However, scientists caution against equating binding affinity with real-world psychoactive effects. Although THCP may offer highly potent therapeutic effects in theory, anecdotal evidence suggests the high it produces may not feel noticeably stronger than that of regular Delta 9 THC strains.
Safety and Regulations Lagging Behind
Unlike other cannabinoids, THCP has seen no human clinical trials, meaning that its potential risks and benefits remain largely speculative. Furthermore, commercial THCP products tend to rely on synthesized forms, raising concerns about manufacturing standards and the absence of regulatory oversight.
MYTH 5: All Synthetic Cannabinoids Are Unsafe and Potential Risks to Your Health
Natural vs. Synthetic Cannabinoids
There’s a common misconception that synthetic cannabinoids are synonymous with harmful substances like K2 or Spice. While it’s true that those chemically engineered products present serious health risks, synthetic cannabinoids like Delta 8 THC or THCP often mimic natural cannabinoids found in hemp.
Delta 8 exists naturally at low levels in hemp plants, but it is typically produced in higher concentrations through chemical processes for commercial use.
That said, many commercially sold “synthetic” cannabinoids have been flagged for contamination. According to liquid chromatography testing, some Delta 8 products sold in unregulated markets contained heavy metals or banned solvents.
This highlights the need for stricter testing standards and certification requirements, like those enforced by FDA-reviewed CBD manufacturers.
Exploring Minor Cannabinoids Beyond Tetrahydrocannabinol (THC) and Cannabidiol (CBD)
The Rising Stars of Minor Cannabinoid Research
- CBG (Cannabigerol): Often referred to as the “mother cannabinoid” because it serves as a precursor to THC, CBD, and other cannabinoids, CBG is gaining attention for its unique benefits. Like CBD, CBG has shown promise in reducing inflammation without inducing psychoactive effects, making it an appealing option for therapeutic use.
- CBN (Cannabinol): Often misunderstood as solely a sedative, CBN’s effects are much more nuanced. While its sedative properties become more pronounced when combined with THC, CBN on its own has shown potential for pain relief and anti-inflammatory effects.It’s also being studied for its potential role in bone healing, stimulating the growth of new bone cells. Though research is still in its infancy, CBN is carving a niche in the wellness industry for those seeking non-psychoactive options for relaxation and recovery.
- CBC (Cannabichromene): This non-psychoactive cannabinoid is particularly intriguing for its ability to amplify the effects of other cannabinoids, a phenomenon known as the “entourage effect.”Studies suggest that when combined with THC, CBC enhances pain-relieving effects, offering potential for future treatments targeting chronic pain or inflammation. Additionally, CBC has shown promise in promoting neurogenesis, the growth of new brain cells, which could have implications for addressing cognitive disorders.
The Entourage Effect in Action
The “entourage effect” refers to the synergistic interaction between various cannabinoids and terpenes, resulting in enhanced therapeutic benefits compared to using isolated compounds.
Initial findings illustrate the importance of using a combination of cannabinoids for certain medical conditions, as the interplay between these compounds can unlock greater efficacy.
More Cannabinoid Systematic Reviews Are Expected to Come
As research into minor cannabinoids accelerates, these rising stars are paving the way for new therapeutic options. From reducing inflammation and pain to promoting relaxation and even stimulating brain cell growth, the potential of cannabinoids beyond THC and CBD is vast.
This emerging field holds the promise of more targeted, effective treatments in the future, benefiting those seeking natural alternatives to conventional medicine. As with any medication or supplement, inform your doctor if you use CBD regularly, so they can periodically monitor your liver enzymes.
The Way Forward in Cannabinoid Research
The rapid growth of the cannabinoid industry has outpaced regulatory frameworks and clinical understanding. With preclinical studies hinting at therapeutic uses for cannabinoids ranging from treating inflammation and joint pain to managing multiple sclerosis and neuropathic pain, the opportunities are undeniable.
However, there is still a critical need for third-party testing, clear labeling, and scientific transparency to protect consumers. Organizations like the National Institute on Drug Abuse (NIDA) and the World Health Organization (WHO) play a vital role in expanding clinical trials and forming internationally relevant guidelines. Meanwhile, FDA-approved CBD manufacturers and hemp product producers must emphasize safety and traceability to combat misinformation.
By bridging cannabinoid research with consumer education, we can unlock the therapeutic potential of compounds like THCA, THCV, Delta 8, THCP, and even minor cannabinoids while mitigating potential risks. Most cannabinoids represent a promising horizon in natural product pharmacology, and their full story is one that science, not speculation, must tell.
