Abstract
Examined the cognitive effects of chronic marijuana use by comparing the performance of 144 marijuana users and 89 nonusers (aged 18-42 yrs) on measures of vocabulary, expression, quantitative thinking, and literary interpretation. Computerized learning and cognitive tests were also administered. Nonusers performed better than either light or heavy users in language skills. On the expression test, the heavy users performed worse than either the nonusers or light users. Although light chronic marijuana use produces no cognitive impairment, it appears that heavy chronic use produces a small but significant impairment of verbal expressive skills without concomitant impairment of vocabulary, reading comprehension, mathematical abilities, or general abilities
