Join our host Dr Leon Barron, General Practitioner and founder of the PCCN as he is joined by a wide range of guests in conversation, keeping you up to date and at the very forefront of developments in the medical cannabis sector.

Dr Mark Smith is an experienced UK-trained GP with interests in chronic disease management, sports injuries and diving, and aviation medicals.  In 2015 looking for a career change and a new challenge, he moved with his wife who is also a GP to Perth in Australia.


Mark was one of the first GPs in Austra lia to prescribe medical cannabis to his patients and began prescribing shortly after legislation change in 2019.


Here he talks about his journey and personal experiences of prescribing and how this has changed his practice and approach to his wider clinical care. He is also uniquely placed to be able to compare and contrast the different approaches taken by Australia and the UK towards access to medical cannabis and the wider role of GPs in prescribing.
