Tetrahydrocannabinol (THC) is the primary psychoactive compound found in the cannabis plant. It interacts with the body's endocannabinoid system, particularly the CB1 receptors in the brain, leading to effects such as euphoria, relaxation, and altered perception. THC is commonly associated with recreational use but also has potential therapeutic benefits. In addition to its psychoactive effects, THC is being studied for its medicinal properties. Research suggests it may help alleviate symptoms related to conditions like chronic pain, nausea, and anxiety. However, its use can also lead to side effects, including impaired memory and coordination.
