This research highlights how cannabis use during adolescence and early adulthood is linked to measurable alterations in brain connectivity. By demonstrating structural changes in regions critical for cognition and emotional regulation, this work provides neurobiological evidence to inform cannabis regulation and education policy. The change we hope to bring is evidence-driven guidance for age restrictions, public health campaigns, and targeted prevention strategies that prioritise brain health in young people. Ultimately, this research bridges neuroscience with policy, enabling more informed, protective, and equitable approaches to cannabis use.
