Cannabis and the brain: What's the long-term impact?

Researchers in New Zealand have used MRI to evaluate the effects of cannabis (or marijuana) on the aging brain. They presented their findings at the International Society for Magnetic Resonance in Medicine (ISMRM) annual meeting in Toronto, Canada, and our report on their work was the most viewed article on in 2023.

For an update, we caught up with Rebecca Lee, a doctoral candidate in medical physics and imaging at the University of Otago and the New Zealand Brain Research Institute. In this video interview recorded on 8 January, she explains how and why the team conducted the study. She also comments on the impact and educational value of the research on the illicit use of cannabis.
