Résumé :
FRANÇAIS :
Deux groupes d'utilisateurs chroniques (fumeurs de charas et buveurs de bang) ont été comparés à un échantillon de non-utilisateurs dix ans après une première évaluation. Les performances sont moins bonnes chez les utilisateurs et montrent une détérioration significative sur le plan cognitif (tests de Wechsler, de vitesse, d'exactitude, temps de réaction, test visuomoteur de Bender) non significative dans le domaine de la personnalité.
ENGLISH :
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 bang users, 19 charas smokers and 15 controls could be re-studied after a lapse of 9-10 years. All the users had continued the use during the intervening years. Tests of intelligence, memory and percetuo-motor tasks earlier administrated 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-users controls. The study thus further corroborates our earlier findings of impairment of cognitive functions associated with long-term, heavy cannabis use.
