Delta-9-Tetrahydrocannabinol, commonly known as THC, is a psychoactive compound found in the cannabis plant. It is the primary cannabinoid responsible for the “high” or intoxicating effect associated with cannabis use. THC functions by binding to specific receptors in the brain and nervous system, leading to various impacts such as altered perception, mood changes, and increased appetite. THC is used medically for its potential therapeutic benefits, such as pain relief, nausea reduction, and appetite stimulation. However, its psychoactive effects also make it a controlled substance in many countries worldwide.
