[kan′əbis]

Etymology: Gk, kannabis, hemp

a psychoactive herb (marijuana) derived from the flowering tops of hemp plants. It has no currently acceptable clinical use in the United States (where it is marketed as marinol) but has been used in the treatment of glaucoma and as an antiemetic in some cancer patients to counter the nausea and vomiting associated with chemotherapy. Cannabis is controlled under Schedule I of the Controlled Substances Act of 1970. All parts of the plant contain psychoactive substances. Cannabinoids, or psychoactive substances synthesized by the hemp plant, include cannabinol, cannabidiol, cannabinolic acid, cannabigerol, cannabicyclol, and several isomers of tetrahydrocannabinol (THC). THC is believed to cause the most characteristic psychologic effects, which include alterations of mood, memory, motor coordination, cognitive ability, and self-perception. Low doses of cannabis seldom impair the ability to perform simple motor tasks but commonly hinder more complex actions, such as driving and flying, which involve complex sensory perception, concentration, and information processing. Cannabis may also enhance the nondominant senses of touch, taste, and smell. Higher doses in some persons can produce delusions, paranoid feelings, anxiety, and panic. This drug also increases the heart rate and systolic blood pressure. Cannabis is about three times more powerful when smoked than when taken orally. Research indicates that some cannabinoids may be therapeutic as anticonvulsants and helpful in reducing intraocular pressure associated with glaucoma. Also called bhang, ganja, grass, hashish, marijuana, pot, reefer, tea, weed.
