Cannabis Use Linked to Reduced Brain Function in Young Adults: Largest Study Yet

A large-scale study examining the effects of cannabis on the brains of 18-to-36-year-olds reveals a link between cannabis use and reduced brain function during cognitive tests. Researchers analyzed data from 1,003 adults, finding that both recent and heavy lifetime cannabis use correlated with significantly lower brain activity during working memory tasks. While the study has limitations, including the inability to establish causality, it highlights the need for further research into cannabis's potential impact on young adult brains. Published in JAMA Network Open, this study provides crucial information for informed decision-making about cannabis use.
