Understanding Cannabinoid Receptors and Their Functions
At Cady Brook Cannabis, we believe that educating our customers about the science behind cannabis products helps everyone make more informed choices. Today, we’re diving into the fascinating world of cannabinoid receptors—the biological system that allows cannabis compounds to interact with our bodies.
What is the Endocannabinoid System?
The endocannabinoid system (ECS) is a complex cell-signaling system that plays a critical role in regulating a range of functions and processes in our bodies, including:
- Sleep
- Mood
- Appetite
- Memory
- Reproduction and fertility
- Inflammation and immune response
The ECS exists and is active in your body even if you don’t use cannabis. It’s composed of three core components: endocannabinoids, receptors, and enzymes.
Understanding CB1 and CB2 Receptors
Cannabinoid receptors are found throughout the body and are a key part of the endocannabinoid system. There are two main types:
CB1 Receptors
CB1 receptors are primarily found in the central nervous system, specifically:
- Brain cortex (controlling mood, cognition)
- Hippocampus (memory)
- Basal ganglia (movement control)
- Cerebellum (motor coordination)
- Hypothalamus (appetite regulation)
THC (tetrahydrocannabinol), the psychoactive compound in cannabis, binds primarily to CB1 receptors, which explains its effects on cognition, memory, and motor functions.
CB2 Receptors
CB2 receptors are mainly found in the peripheral nervous system, particularly in immune cells such as:
- B cells
- T cells
- Macrophages
- Microglia in the brain
- Peripheral tissues (skin, liver, etc.)
CBD (cannabidiol) doesn’t bind directly to either receptor but instead works by inhibiting the breakdown of endocannabinoids, allowing them to have more effect on your body.
How Cannabis Compounds Interact With These Receptors
When you consume cannabis products, phytocannabinoids (plant-derived cannabinoids) mimic our body’s own endocannabinoids and interact with our cannabinoid receptors in various ways:
- THC: Acts as a partial agonist at CB1 receptors, binding directly and activating them, which produces the “high” sensation.
- CBD: Works indirectly, influencing receptor activity without binding directly. It can modulate THC’s effects and work through other non-cannabinoid receptors.
- CBG (Cannabigerol): Binds to both CB1 and CB2 receptors but with less potency than THC.
- CBN (Cannabinol): Has a higher affinity for CB2 receptors but is only mildly psychoactive.
The Entourage Effect
The entourage effect refers to how cannabinoids work better together than in isolation. This synergistic relationship between various compounds in cannabis can enhance therapeutic effects while reducing adverse reactions.
For example, CBD can mitigate some of THC’s anxiety-inducing effects by influencing how THC binds to CB1 receptors. Terpenes (aromatic compounds in cannabis) also contribute to this effect by influencing how cannabinoids interact with receptors.
Practical Applications
Understanding cannabinoid receptors can help consumers make more informed choices when selecting cannabis products:
- For anxiety relief: Products with balanced THC:CBD ratios may provide anxiety relief without excessive psychoactivity.
- For inflammation: Products targeting CB2 receptors may help with inflammatory conditions.
- For sleep issues: Combinations that influence both receptor types may be beneficial for sleep regulation.

Future Research
Scientists continue to discover new aspects of the endocannabinoid system. Recent studies suggest there may be additional cannabinoid receptors beyond CB1 and CB2, such as GPR55, which some researchers refer to as “CB3.”
Understanding these complex receptor interactions helps advance our knowledge of how cannabis compounds work and could lead to more targeted therapeutics in the future.
We hope this technical dive into cannabinoid receptors helps you understand the science behind the products we offer at Cady Brook Cannabis. Next time you visit our dispensary in Webster, MA, feel free to ask our staff about how specific products might interact with your endocannabinoid system!
