THC, or tetrahydrocannabinol, is the primary psychoactive compound found in cannabis (marijuana). It is responsible for the “high” that users experience when consuming marijuana. THC interacts with the body’s endocannabinoid system, particularly by binding to cannabinoid receptors in the brain and nervous system. This interaction can influence various physiological and psychological processes, including mood, memory, appetite, and pain perception.
THC is one of over 100 cannabinoids identified in the cannabis plant and is often the subject of research regarding potential medicinal benefits, such as pain relief and appetite stimulation, as well as recreational use. Its legality varies by region, with some places permitting its recreational and medicinal use, while others maintain strict regulations.
