Understanding the Endocannabinoid System and Cannabis: The Interplay between Endocannabinoids, Phytocannabinoids, and Terpenes
Introduction:
The endocannabinoid system (ECS) is a vital part of the human body that plays a critical role in regulating various physiological processes. These processes are fundamental to the human experience, including pain, mood, appetite, and sleep. The ECS is made up of a network of receptors, neurotransmitters, and enzymes. These components interact with endocannabinoids, which are naturally produced by the body, and phytocannabinoids, which are found in plants such as cannabis.
In this article, we will explore the intricacies of the endocannabinoid system and the role that endocannabinoids and phytocannabinoids can play in this complex network. We will also touch on the concept of the “entourage effect”. This refers to the way in which different cannabinoids and terpenes interact with each other and the endocannabinoid system to produce a more potent effect.
What are Endocannabinoids?
Endocannabinoids are naturally occurring compounds that are produced by the body and interact with the endocannabinoid system. The two main endocannabinoids are anandamide and 2-arachidonoylglycerol (2-AG). Anandamide is known for its role in regulating mood, appetite, and pain perception, while 2-AG plays a role in regulating inflammation and immune system function.
The endocannabinoid system works by receiving signals from the endocannabinoids and transmitting them to the appropriate receptors in the body. It is present throughout your body, and connects the brain, the digestive system, the reproductive system, the immune system, and the cardiovascular system, among others. Thus, this system helps to maintain balance, or homeostasis, in the body. It also plays a role in regulating processes such as pain perception, mood, appetite, and sleep.
What are Phytocannabinoids?
Phytocannabinoids are the cannabinoids found in the cannabis plant, including both hemp and marijuana. Phytocannabinoids can also be found in plants such as Echinacea and ‘Electric Daisy’ albeit in lower concentrations than cannabis.
Phytocannabinoids interact with the endocannabinoid system in a similar way to endocannabinoids. They can produce different effects depending on the receptors they interact with, and the other cannabinoids and terpenes present in the plant.
The two most well-known phytocannabinoids are THC (tetrahydrocannabinol) and CBD (cannabidiol). THC is the psychoactive compound that is responsible for the “high” associated with marijuana use. CBD, on the other hand, is non-psychoactive and is known for its potential health benefits, such as reducing anxiety and inflammation. However, there are over 100 different phytocannabinoids found in the cannabis plant alone.
Each cannabinoid has its own unique chemical structure. The unique shape of the molecule is responsible for the properties and potential health benefits associated with each particular cannabinoid. Some of the less well known phytocannabinoids include CBN (cannabinol), CBG (cannabigerol), and THCV (tetrahydrocannabivarin). As cannabis breeding progresses, consumers will have increasing access to a variety of novel cannabinoids.
Terpenes and the Entourage Effect:
Terpenes are fragrant oils found in many plants, including the cannabis plant. They have been shown to interact with the endocannabinoid system and with other cannabinoids to produce a more potent or somehow altered effect. This phenomenon is known as the “entourage effect.”
For example, the terpene myrcene has been shown to enhance the effects of THC and other cannabinoids by increasing their absorption rate. Similarly, the entourage effect can also be used to describe interactions between different cannabinoids. For instance, CBD has been shown to have a potentiating effect on THC, reducing its psychoactive effects and making it more tolerable for some people.
Interaction between Cannabinoids and the endocannabinoid system:
Different cannabinoids can interact with different receptors in the endocannabinoid system to produce different effects. For example, CBD has been shown to interact with the 5-HT1A receptor, which is involved in regulating mood. THC however, interacts with the CB1 receptor, which is involved in regulating pain perception and appetite.
The interaction between cannabinoids and the endocannabinoid system is complex and multi-faceted as we have seen. Different cannabinoids and terpenes interacting with each other, and with different receptors, produce varying effects. As we discover more about the interactions between these compounds, we can better predict the potential benefits and effects of different cannabis-based products. This is one reason why test results should accurately reflect concentrations of cannabinoids and terpenes present in the product.
Conclusion:
In conclusion, the endocannabinoid system is a complex and vital part of the human body. Endocannabinoids and phytocannabinoids can play a critical role in regulating various physiological processes. The entourage effect is an important key to our understanding of cannabis medicine. As we know, different cannabinoids and terpenes interact with each other, and with the endocannabinoid system to produce a more potent effect.
Understanding the intricacies of the endocannabinoid system and the interaction between these compounds is critical. With this knowledge, we will better understand the potential benefits and effects of different cannabis-based products.
