University of California San Diego researchers published a study in Neuropsychology finding that teenagers who begin using cannabis show slower gains in thinking and memory skills as they develop. The study analyzed data from more than 11,000 participants drawn from the Adolescent Brain Cognitive Development (ABCD) Study, the largest long-term study of brain development in U.S. youth. The research represents the most comprehensive U.S. examination to date of how cannabis affects adolescent cognitive development, providing evidence that marijuana use during the teenage years may impair the normal progression of cognitive skill acquisition during this critical developmental period.
