A cannabinoid is a type of chemical compound that interacts with the body's endocannabinoid system, which helps regulate various functions such as mood, appetite, and pain sensation. Cannabinoids can be found in the cannabis plant, where they are produced naturally, but they can also be synthesized in laboratories. There are over 100 different cannabinoids, with the most well-known being tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is primarily responsible for the psychoactive effects of cannabis, while CBD is often used for its potential therapeutic benefits without causing a "high."
