THC
THC (tetrahydrocannabinol, specifically delta-9-THC) is the primary psychoactive compound in cannabis responsible for the euphoric "high." It binds to CB1 receptors in the brain and nervous system, affecting mood, perception, appetite, pain, and memory. THC content in flower typically ranges from 10-30%. Medical applications include pain management, nausea reduction, appetite stimulation, and sleep assistance. THC is classified as a Schedule I substance federally in the United States.
