A review of the therapeutic potentials of the cannabinoids is presented. With respect to the antifertility aspects of cannabinoids, 2 mg delta 9-THC suppressed luteinizing hormone secretion in rats and 2 and 3 mg/kg resulted in a deterioation of male sexual performance. A new chapter in marijuana research was opened in 1964 with the identification of delta 9-tetrahydrocannabinol as the active ingredient. Antiedema, analgesic, antipyretic, antiinflammatory, antifertility, antiepileptic, anticonvulsant, antihypertensive, cardiotonic, pulmonary, and antidepressant effects along with potentiation of barbiturates and analgesics are reviewed leading one to the conclusion that marijuana is "a drug for all reasons". During the past decade many investigators have pursued the possibility of modification of the delta 9 structure to delineate activities. 1 compound, Abbott 40656, SP106, a water-soluble benzopyran derivative is presently under Phase 1 clinical evaluation as a sedative-hypnotic.
