What are Cannabinoids
Cannabinoids are naturally occurring compounds found primarily in the cannabis plant (Cannabis sativa). They are responsible for the diverse effects and potential therapeutic properties associated with cannabis use. The term “cannabinoid” is derived from “cannabis” and the suffix “-oid,” which means “resembling” or “like,” indicating that these compounds are unique to the cannabis plant.
There are over 100 known cannabinoids, each with distinct chemical structures and biological effects. These compounds interact with the body’s endocannabinoid system (ECS), a complex cell-signaling system that maintains homeostasis, or balance, within the body. The ECS regulates various physiological and cognitive processes, including pain sensation, mood, appetite, sleep, and immune system function.
The two most well-known and widely studied cannabinoids are delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is the primary psychoactive compound in cannabis, responsible for the characteristic “high” experienced by users. Conversely, CBD is non-psychoactive and associated with various potential health benefits without mind-altering effects.
In addition to THC and CBD, there are many other cannabinoids, such as cannabinol (CBN), cannabigerol (CBG), and cannabichromene (CBC), each with its unique properties and potential therapeutic applications. Research into the effects and uses of these lesser-known cannabinoids is ongoing, and new compounds continue to be discovered.
Cannabinoids can also be classified as endogenous (naturally produced within the body), phytocannabinoids (derived from plants, primarily cannabis), and synthetic cannabinoids (artificially created in a laboratory). Endogenous cannabinoids, or endocannabinoids, are produced by the body as part of the ECS and serve as chemical messengers to help maintain homeostasis. Phytocannabinoids, such as THC and CBD, are naturally occurring plant compounds. At the same time, synthetic cannabinoids are designed to mimic the effects of natural cannabinoids but often have more potent and unpredictable results.
Cannabinoids have become a subject of intense scientific investigation due to their potential therapeutic applications and unique interactions with the body’s endocannabinoid system (ECS). As our understanding of cannabinoids has expanded, researchers have identified three main types of cannabinoids:
- The body naturally produces endocannabinoids which are essential components of the ECS. The primary endocannabinoids are anandamide (AEA) and 2-arachidonoylglycerol (2-AG). They function as neurotransmitters, binding to cannabinoid receptors (CB1 and CB2) throughout the body to modulate various physiological and cognitive processes. In addition, endocannabinoids play a critical role in maintaining homeostasis by facilitating communication between cells and regulating the release of other neurotransmitters.
- Phytocannabinoids are plant-derived cannabinoids found primarily in the cannabis plant, although some other plants also produce similar compounds. Phytocannabinoids interact with the body’s ECS in a similar way to endocannabinoids. The most well-known phytocannabinoids are THC and CBD. However, other essential phytocannabinoids include CBN, CBG, CBC, and THCV, each with unique properties and potential health benefits. In addition, the full spectrum of phytocannabinoids found in cannabis plants is thought to have a synergistic effect, known as the “entourage effect,” which may enhance the therapeutic potential of individual cannabinoids.
- Synthetic cannabinoids: These are artificially created compounds designed to mimic the structure and function of natural cannabinoids. They are typically produced in laboratories for research purposes or as active ingredients in some pharmaceutical drugs. Synthetic cannabinoids can be more potent than their natural counterparts and are often associated with more severe side effects. Examples of synthetic cannabinoids include dronabinol (Marinol), nabilone (Cesamet), and the controversial “Spice” or “K2” compounds found in some illicit synthetic cannabis products.
As research on cannabinoids continues progressing, scientists are discovering new ways to harness these compounds for medical and therapeutic purposes. For example, studies have demonstrated the potential of cannabinoids to treat a range of conditions, including chronic pain, epilepsy, multiple sclerosis, anxiety, and many others. Additionally, ongoing research is exploring the use of cannabinoids in cancer treatment, neurodegenerative diseases, and other areas of medicine.
Cannabinoids represent a diverse and complex group of compounds with significant potential for therapeutic applications. Their unique interactions with the body’s endocannabinoid system have sparked intense scientific interest, leading to new cannabinoids and a deeper understanding of their mechanisms of action. As our knowledge of cannabinoids expands, so does the potential for developing innovative new treatments and therapies for various health conditions.
Latest Uses of Cannabinoids
there have been several promising developments in using cannabinoids for various medical and therapeutic purposes. Here are some of the latest services and areas of research related to cannabinoids:

- Cancer treatment: There is ongoing research into the potential use of cannabinoids, including their ability to reduce tumor growth, enhance the efficacy of conventional cancer treatments, and alleviate cancer-related symptoms like pain and nausea.
- Glaucoma: Some studies suggest that cannabinoids, mainly THC, may help reduce intraocular pressure in individuals with glaucoma, providing temporary relief for this eye condition.
- Sleep disorders: Cannabinoids, particularly CBN and CBD, are being explored for their potential soothing effects and ability to improve sleep quality in individuals with sleep disorders such as insomnia.
- Inflammatory and autoimmune conditions: Cannabinoids, especially CBD, have demonstrated anti-inflammatory properties, making them a potential treatment option for rheumatoid arthritis, Crohn’s disease, and psoriasis.
- Appetite stimulation: Cannabinoids like THC and CBN have been shown to stimulate appetite, which could benefit patients experiencing appetite loss due to medical conditions or treatments like chemotherapy.
It is important to note that while a growing body of research supports these uses, many studies are still in their early stages, and further research is needed to understand the therapeutic potential of cannabinoids fully. Additionally, the legal status of cannabinoids varies by jurisdiction, and their use for medical purposes should always be discussed with a healthcare professional.
The Endocannabinoid System: How Cannabinoids Interact with Our Bodies
Cannabinoids, naturally occurring in the body or derived from external sources like the cannabis plant, interact with our bodies through the endocannabinoid system (ECS). The ECS is a complex cell-signaling network that plays a crucial role in maintaining homeostasis, the stable balance of internal conditions necessary for optimal health and well-being.
The ECS comprises three main components: endocannabinoids, receptors, and enzymes. Endocannabinoids are lipid-based signaling molecules that are naturally produced by our bodies. The primary endocannabinoids are anandamide (AEA) and 2-arachidonoylglycerol (2-AG). These molecules are similar in structure to plant-based cannabinoids so that they can interact with the same receptors in the ECS.
There are two main types of receptors in the ECS: CB1 and CB2. CB1 receptors are primarily found in the brain and central nervous system, while CB2 receptors are more prevalent in the immune system and peripheral tissues. Endocannabinoids and plant-based cannabinoids, such as THC and CBD, bind to these receptors, influencing a wide range of physiological processes, including:
- Hormone levels and fertility
- Heart rate
- Body temperature
- Hunger and digestion
- Immune function
- Memory and concentration
- Motor control
- Sensory perception
Enzymes are responsible for breaking down endocannabinoids once they have fulfilled their function. The primary enzymes involved in this process are fatty acid amide hydrolase (FAAH), which breaks down anandamide, and monoacylglycerol lipase (MAGL), which degrades 2-AG.
Endocannabinoids work precisely, targeting only the systems that need to be regulated at any moment. However, when cannabinoids from external sources, such as cannabis, are introduced into the body, they can have a more widespread effect, potentially causing both desirable and undesirable changes simultaneously. This is one reason why the therapeutic use of cannabinoids requires careful consideration of dosages and potential side effects.
The endocannabinoid system plays a vital role in regulating numerous physiological processes and maintaining overall balance in the body. Therefore, understanding the interactions between cannabinoids and the ECS is essential for unlocking the full therapeutic potential of these compounds and developing targeted treatments for a wide range of medical conditions.
Cannabinoids and the FDA: Current Approvals and Future Prospects
As research on the therapeutic potential of cannabinoids continues to advance, the FDA has approved a few medications derived from these compounds. At present, there are three FDA-approved cannabinoid-based drugs:
- Marinol (dronabinol): A synthetic form of THC approved for the treatment of chemotherapy-induced nausea and vomiting (CINV) and for appetite stimulation in patients with AIDS-related wasting syndrome.
- Cesamet (nabilone): Another synthetic THC compound, also approved for the management of chemotherapy-induced nausea and vomiting in patients who have not responded well to conventional antiemetic treatments.
- Epidiolex: A purified CBD formulation approved for the treatment of two rare and severe forms of childhood epilepsy, Lennox-Gastaut syndrome and Dravet syndrome.
The limited number of FDA-approved cannabinoid-based medications can be attributed to the early research stage and the stringent requirements set by the FDA. For example, to gain approval, new drugs must undergo extensive clinical trials involving many participants to assess the safety and efficacy of the treatment for specific patient populations.
Conducting such large-scale studies is a time-consuming, expensive, and complex process. However, as more research is conducted and additional evidence of the therapeutic benefits of cannabinoids is uncovered, more cannabinoid-based drugs will likely be developed and approved for a wider variety of medical conditions.
Regarding the legal status of cannabinoids, hemp-derived CBD products with less than 0.3% THC are permitted at the federal level in the United States. However, marijuana and marijuana-derived products remain illegal at the federal level even though many states have legalized marijuana for medical or recreational use. Therefore, it is essential to be aware of your state’s laws and consult with a healthcare professional before using cannabinoid-based products for medical purposes.
Top 11 Hemp Derived Cannabinoids
- Hemp-derived cannabinoids are compounds found in the Cannabis sativa plant, specifically the hemp variety, which contains less than 0.3% THC. Here are the top 5 hemp-derived cannabinoids known for their potential therapeutic benefits:
- CBD (Cannabidiol): CBD is the most abundant cannabinoid found in hemp and is well-known for its potential therapeutic properties. It has been studied for its anti-inflammatory, analgesic, anti-anxiety, and neuroprotective effects. In addition, CBD is non-psychoactive, meaning it does not produce the “high” associated with THC.
