During the lecture, titled Comorbidity, collaboration and compassion, Professor Bowden Jones spoke about co-morbidity and new evidence-based recommendations for clinicians and service providers. The talk included a case study on cannabis use and its link to mental illness, and was followed by a panel discussion with plenty of opportunity for the audience to ask questions. Joining Owen on the panel were Dr Emily Finch, chair of the Addictions Faculty, and Dr Jonathan Dewhurst, clinical lead for addiction services at Greater Manchester Mental Health NHS Foundation Trust, as well as expert by experience Melinda King.
