CANNABIS AND COGNITIVE FUNCTIONS. A RE-EVALUATION

Out of 25 each of long-term, heavy bhang (marihuana) ingestors, 25 charas (hashish) smokers and 25 matched non-user controls earlier studied and reported by us, 11 bhang users, 19 charas smokers and 15 controls could be restudied after a lapse of 9-10 years. All users had continued the use during the intervening years. Tests of intelligence, memory and perceptuo-motor tasks earlier administered to the subjects were repeated. This showed a significant additional deterioration in case of the users on a number of psychological measures, i.e. on digit span, speed and accuracy tests, reaction time and Bender visuo-motor gestalt test. The deterioration in the cannabis users was significantly greater than in the case of the non-user controls. The study thus further corroborates earlier findings of impairment of cognitive functions associated with long-term heavy cannabis use.
