Although significant advances have been made in recent years in the clinical evaluation of detrimental effects induced by developmental marijuana exposure, prospective longitudinal studies are currently underway. So far, they have preferentially investigated the cognitive effects of prenatal exposure to cannabis, with... 

Altered perception of the passage of time is the second common cognitive effect of cannabis (Chait Pierri, 1992). This is perhaps best described in statements like a few minutes seemed to pass like hours. Phe effect has been noted in both surveys and the experimental literature. However, the time distortion is not as pronounced in the research reports as it is in more subjective self-reports pro ided by marijuana users.

From a potency standpoint, the results were less than exciting. At low doses, performance scores did decline slightly and some subjects reported mild symptoms suggestive of marijuana effects. However, a substantial alteration in both cognitive performance and mood occurred only in one of the two individuals who received the highest dose (60 mcg/kg). This volunteer clearly showed a drop in performance scores, and developed clear-cut signs and symptoms of a marijuana high.

A9-Tetrahydrocannabinol (A9-THC) is considered to be the predominant compound in preparations of C. sativa (marijuana, hashish, bhang) that is responsible for the central nervous system effects in humans. The recognized central nervous system responses to these preparations include alterations in cognition and memory, euphoria, and sedation. Potential therapeutic applications of cannabis preparations that are of either historical or contemporary interest include analgesia, attenuation of the nausea and vomiting of cancer chemotherapy, appetite stimulation, decreased intestinal motility of diarrhea, decreased bronchial constriction of asthma, decreased intraocular pressure of glaucoma, antirheumatic and antipyretic actions, and treatment of convulsant disorders. These effects have been reviewed recently (Howlett, 1995).
