cannabis

A drug derived from the hemp plant. Marijuana is the dried leaves, flowers or stems of various species of the hemp grass Cannabis , especially Cannabis sativa , Cannabis indica and Cannabis americana . Cannabis resin contains the cannabinoid tetrahydrocannabinol which produces euphoria (the easy promotion of silly laughter or giggling) and an apparent heightening of all the senses, especially vision, with distortion of dimensions. There is slowing of reflexes, distortion of distance and alteration in the sense of responsibility. Driving becomes dangerous. Much valued is an illusory sense of deep philosophical insight or a conviction of omniscience. Panic attacks or acute anxiety may occur, and SCHIZOPHRENIA, MANIA, DEPERSONALIZATION or confusional psychoses have been precipitated. Persistent heavy users may become apathetic and show loss of interest and concern (amotivational syndrome). Cannabis does, however, have some valuable medical uses. It is a sedative that can relieve some side effects of drugs and can help some patients to live more comfortably with some serious illnesses. The former rigidity of official attitude against its therapeutic use is softening, especially since cannabinoid receptors were found to be widely expressed throughout the central nervous system. A number of American States have approved its medical use. See also GLUTAMATE.
