Study Finds Cannabis Usage in Middle Aged and Older Adults Associated With Larger Brain Volume, Better Cognitive Function
Summary
New CU Anschutz study using UK Biobank data finds that lifetime cannabis use in adults aged 40-77 is generally associated with larger brain volumes and better cognitive performance, especially at moderate use. The results are nuanced, with one region showing lower volume at higher use and several caveats about usage patterns, potency, and aging context.
