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 the most well-known examples are tetrahydrocannabinol (THC) and cannabidiol (CBD). In addition to those found in cannabis, cannabinoids can also be produced synthetically in laboratories. These compounds can have different effects on the body, depending on their structure and how they interact with cannabinoid receptors. Research into cannabinoids is ongoing, exploring their potential therapeutic benefits and applications.
