Cannabis Use Linked to Brain Changes and Psychosis Risk in Youth

A study from McGill University reveals that cannabis use exacerbates reduced synaptic density in young adults at risk of psychosis, worsening brain connectivity deficits linked to social withdrawal and motivational issues. This research, using advanced brain scanning, is the first to measure real-time structural brain changes in high-risk individuals, potentially paving the way for new therapies targeting social and functional deficits in psychosis. The findings highlight the need for early intervention strategies and further investigation into cannabis's impact on brain development.
