'''Δ-9 Tetrahydrocannabinol''' is the primary active ingredient in [[Marijuana]]. It is an aromatic terpenoid, whose aromatic rings make it comparatively insoluble in water, but has better solubility in alcohols and lipids. The hypothesized reason for production of THC in the plant is as a defense mechanism against insects; the effect of THC on insect nervous systems is that of a paralytic, but the mechanisms are still unknown.
