-Caveat Lector- Study suggests pot's effect on IQ is temporary
Copyright � 2002 Agence France-Presse TORONTO (April 2, 2002 2:37 p.m. EST) - Marijuana use has no long term effects on a user's intelligence, according to a study appearing in the Journal of the Canadian Medical Association Tuesday. Canadian researchers, however, cautioned that their findings should be interpreted cautiously, saying more research is needed to determine if pot ingestion affects specific cognitive activities, such as attention or memory. The preliminary study by Carleton University researchers in Ottawa evaluated the intelligence quotient of 70 people aged 17-20 through self-reporting and urinalysis and compared it to their IQ score at 9-12 years old before initial drug use. Although the intelligence of a group of heavy users who smoked five or more joints weekly differed from that of light pot smokers, "a negative effect (in IQ) was not observed among subjects who had previously been heavy users but were no longer using the substance." It is well-documented that marijuana use can cause acute cognitive changes that last for several hours after use, but researchers were trying to determine if its use produces a negative effect beyond that time period. "We conclude that marijuana does not have a long-term negative impact on global intelligence," said Peter Fried, a professor of psychology. The researchers pressed for more study on the issue, saying their results may have been moderated by the small number of participants, the length of time the drug was used, the number of joints smoked or the young age of the subjects. "It is also important to emphasize that broad intellectual functioning may be less vulnerable to the consequences of marijuana use than more specific cognitive domains, such as attention and memory," they said. ------------------------ "In little more than a year we have gone from enjoying peace and the most prosperous economy in our history, to a nation plunged into war, recession and fear.
