The Science Behind Cannabis Extracts: How They Work in the Body


Cannabis extracts have gained popularity in recent years for their potential therapeutic benefits. From relieving pain and inflammation to reducing anxiety and stress, cannabis extracts have shown promise in treating a variety of conditions. But how exactly do these extracts work in the body? Let’s explore the science behind cannabis extracts and how they interact with the body’s endocannabinoid system.

The Endocannabinoid System

The endocannabinoid system is a complex network of receptors and neurotransmitters found throughout the body. It plays a key role in regulating various physiological processes, including mood, memory, appetite, and pain sensation. The two primary receptors in the endocannabinoid system are known as CB1 and CB2 receptors.

CB1 receptors are primarily found in the brain and central nervous system, while CB2 receptors are predominantly located in the immune system and peripheral tissues. When cannabis extracts are consumed, the active compounds, known as cannabinoids, interact with these receptors, activating a cascade of chemical reactions that influence the body’s response to pain, inflammation, and other processes.


Two of the most well-known cannabinoids found in cannabis extracts are tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is the psychoactive compound responsible for the “high” sensation often associated with cannabis use, while CBD is non-psychoactive and has been shown to have various health benefits.

THC binds primarily to CB1 receptors in the brain, leading to the euphoric effects commonly experienced when consuming cannabis. On the other hand, CBD interacts with both CB1 and CB2 receptors, but in a different way. CBD does not directly bind to these receptors but instead modulates their activity, promoting a sense of relaxation and well-being without the psychoactive effects of THC.

How Cannabis Extracts Work in the Body

When cannabis extracts are consumed, whether through smoking, vaping, or ingesting, the cannabinoids are absorbed into the bloodstream and transported throughout the body. Once in the body, the cannabinoids interact with the endocannabinoid system, binding to the CB1 and CB2 receptors and influencing their activity.

Depending on the specific cannabinoid profile of the extract, different effects can be experienced. For example, a high THC extract may provide pain relief and euphoria, while a CBD-dominant extract may reduce anxiety and promote relaxation. The terpenes, aromatic compounds found in cannabis extracts, also play a role in the overall effect by modulating the interaction between cannabinoids and receptors.

Benefits of Cannabis Extracts

Research has shown that cannabis extracts have the potential to alleviate a wide range of symptoms and conditions, including chronic pain, inflammation, epilepsy, anxiety, and depression. Some studies have also indicated that cannabis extracts may have neuroprotective and anti-cancer properties, although more research is needed to fully understand these effects.

In addition to their therapeutic benefits, cannabis extracts are also being used recreationally for their relaxing and mood-enhancing effects. However, it is important to note that individual responses to cannabis extracts can vary, and some people may experience adverse effects such as paranoia, dizziness, or impaired coordination.


Overall, the science behind cannabis extracts reveals a complex interplay between cannabinoids, receptors, and neurotransmitters in the body’s endocannabinoid system. By understanding how these compounds work, researchers can continue to explore the potential therapeutic uses of cannabis extracts and develop new ways to harness their benefits while minimizing any potential risks.

Whether used for medical purposes or recreational enjoyment, cannabis extracts have the potential to offer relief and enhance well-being for many individuals. As more research is conducted and regulations evolve, the full potential of cannabis extracts may be further unlocked, providing new avenues for improving health and quality of life.
