Lifetime cannabis use linked to younger-looking brains in a 25k-participant study
TL;DR Summary
A large UK Biobank imaging study of over 25,000 participants aged 44–81 found that lifetime cannabis users have brain connectivity patterns that resemble younger brains and outperformed non-users on several cognitive tests, with aging-related networks showing opposite changes; however, being cross-sectional and based on lifetime use, the study cannot establish causation and the effects are modest.
