What are cannabinoids?

Cannabinoids (e.g., THC and CBD) are the chemical compounds secreted by cannabis flowers that can affect the human body. They work by imitating compounds our bodies naturally produce, called endocannabinoids, that affect nerve, brain and immune cell activity.

Currently, there are two known primary cannabinoid receptors: CB1 and CB2 receptors. CB1 receptors are located in the central nervous system, and in some peripheral tissues. They affect appetite, muscle control, pain, cognition, thermoregulation, and our stress response. CB2 receptors are primarily found in immune cells, and at a lower density in the central nervous system. CB2 activation is associated with function and immune cell proliferation, inflammation, and pain. Although these two cannabinoid receptors have been studied relatively extensively, there are more cannabinoid receptors being examined.
