About Caitlin McClure-Thomas: Caitlin is a PhD candidate at The University of Queensland’s National Centre for Youth Substance Use Research. Her research explores how cannabis messaging shapes people’s attitudes, beliefs, and behaviours.

Her work seeks to inform evidence-based approaches to harm reduction and contribute to discussions about cannabis regulation.
