Justin Sinclair (CSO, ANTG) is a researcher and pharmacognosist who has been formally studying medicinal plants and fungi for more than 25 years. His work sits at the intersection of traditional botanical knowledge and modern clinical science, with a particular focus on how plant-based medicines can be used safely, effectively, and ethically in patient care.

Justin has been closely involved in the evolution of medicinal cannabis science and research in Australia since its earliest regulatory reforms. In 2015, he was appointed to the Scientific Advisory Board of United in Compassion, the patient advocacy organisation that played a pivotal role in changing Australia’s medicinal cannabis laws. He later became a board member of the Australian Medicinal Cannabis Association (AMCA) in 2020, contributing to industry standards and professional dialogue.

Justin also advises Cannabis Clinicians Australia (CCA) on technical and scientific matters, and has been deeply involved in medicinal cannabis education since 2016, delivering more than 150 lectures to healthcare professionals, industry leaders, and patient groups across Australia and New Zealand.

Justin is currently completing his doctoral research at the NICM Health Research Institute (Western Sydney University) where he is investigating the safety, tolerability, and effectiveness of medicinal cannabis for endometriosis. Since 2016, he has published 5 book chapters and 25 peer-reviewed journal articles on medicinal cannabis.

Outside of his academic work, Justin enjoys spending time in old-growth forests, learning from First Nations peoples about medicinal plants, and - perhaps unsurprisingly - tending his own garden.
