Understanding CB1 and CB2 Receptors: The Science Behind CBD for Pets
There are two main types of receptors that cannabinoids interact with to create effects in the body — CB1 and CB2. These receptors make up a key part of what is known as the endocannabinoid system (ECS), a network responsible for maintaining balance and wellness in mammals, including dogs and cats.
CB1 vs. CB2: What’s the Difference?
CB1 Receptors: These are primarily located in the central nervous system (brain and spinal cord). They play a major role in regulating mood, anxiety levels, and overall alertness.
CB2 Receptors: These are primarily found in the peripheral nervous system and immune cells. They influence pain perception, inflammation, and immune response. Together, CB1 and CB2 receptors work to keep your pet’s body in balance.
Did You Know? Dogs have more cannabinoid receptors than most mammals, which is why it’s important to choose pet-specific CBD products with proper dosing guidelines.
Plant-Based Cannabinoids and Your Pet
Plant-based cannabinoids (phytocannabinoids) like CBD can also bind to CB1 and CB2 receptors. While THC is responsible for the psychoactive “high” in marijuana, CBD is non-intoxicating and delivers most of the health benefits associated with hemp.
The 2018 Farm Bill made hemp (containing less than 0.3% THC) legal in the United States, making it possible for pets to enjoy the benefits of CBD without the risk of intoxication.
