The connoisseurs hold out for (−)-trans-Δ9-tetrahydrocannabinol.
THC, or Δ9-tetrahydrocannabinol, is the principal psychoactive compound found in cannabis. Its molecular formula is C21H30O2, and its structure allows it to interact with cannabinoid receptors in the human nervous system. THC acts primarily as a partial agonist of CB1 receptors in the brain, altering neurotransmitter release and producing changes in perception, mood, memory, coordination, and appetite. It can also activate CB2 receptors, which are more closely associated with immune tissues. Its effects vary with dose, route of administration, and individual physiology. THC is used in research, pharmaceuticals, and recreational products.
