What are “cannabinoid receptors”?

Cannabinoid receptors are specialized proteins located on the surface of cells that have the ability to interact with cannabinoids, which are naturally occurring compounds found in cannabis as well as other substances that mimic their effects. When cannabinoids bind to these receptors, they trigger various physiological responses within the body, which can influence a range of functions such as mood, appetite, pain sensation, and memory.

These receptors are part of the endocannabinoid system, which plays an essential role in maintaining homeostasis and regulating many bodily processes. The most well-known cannabinoid receptors are CB1 and CB2. CB1 receptors are primarily found in the brain and are associated with the psychoactive effects of THC, while CB2 receptors are mainly found in the immune system and are thought to modulate inflammation and pain.

The other options do not accurately describe cannabinoid receptors. They are not exclusive to the brain, as they are also found throughout the body. Additionally, they are not components of the cannabis plant itself but rather are part of the human and animal physiology that interacts with cannabinoids. Finally, cannabinoid receptors do not solely activate in response to high doses of THC; they can be engaged by various cannabinoids, including those produced by the body's own endocannabinoid system, regardless of dosage
