Cannabis, also known as marijuana or ganja, is a psychoactive product of the plant Cannabis sativa L. subsp. indica (= C. indica Lam.). The herbal form of the drug consists of dried mature flowers and subtending leaves of pistillate ("female") plants. The resinous form, known as hashish, consists primarily of glandular trichomes collected from the same plant material. The major biologically active chemical compound in cannabis is Δ9-tetrahydrocannabinol (delta-9-tetrahydrocannabinol), commonly referred to as THC.
