The Lancet Psychiatry in conversation with

People with psychosis experience poor physical as well as mental health and infringement of their human rights in several spheres. How is this being addressed through legal frameworks? Which interventions most effectively support recovery of people with psychosis?
In this episode of In Conversation With, hosted by Joan Marsh (Editor-in-Chief, The Lancet Psychiatry), seven leading researchers from around the world discuss two in-depth reviews published in the journal that explore these questions with an emphasis on perspectives from low- and middle-income countries.

What does the science actually say about cannabis and mental health? In this episode of In Conversation With, hosted by Dustin Graham (Deputy Editor, The Lancet Psychiatry), three leading researchers unpack a landmark collection of papers on cannabis and mental health published in the journal.

Dr. Jack Wilson (University of Sydney) breaks down a comprehensive meta-analysis of randomised controlled trials, revealing striking evidence gaps. Dr. Wayne Hall (University of Queensland) synthesises multiple forms of evidence, exploring cannabis's complex relationship with psychosis, anxiety, and depression. Professor Tom Freeman (University of Bath) zooms out to examine international cannabis policy, from decriminalisation to commercial legalisation, and what those shifts mean for psychiatric outcomes.

Together, they tackle the tension between public demand, commercial interests, and a rapidly evolving evidence base — and what policymakers and clinicians urgently need to know.

How can you stop traumatic flashbacks in just one session?

Intrusive memories are so common after experiencing traumatic events and are one of the hallmark features of PTSD, but what if you could take away the power of those images without having to discuss them at length in therapy? In this episode, Emily Holmes talks about a new randomised controlled trial of an imagery-competing task, where participants are taught in just one guided session to recall a traumatic memory and then use mental rotation and playing Tetris, which had a strong effect on reducing intrusive memories and PTSD symptoms.  We talk about the neuroscience-informed development of this approach to trauma, and the importance of finding scalable and accessible approaches in psychological intervention research.

Can personality disorder treatments be reduced to just a few months?

The evidence base for personality disorder treatments, like dialectical behavioural therapy (DBT) or mentalisation-based treatment (MBT), points towards treatments that last at least a year. Within the mental health field in general, though, in many countries there's a drive towards offering shorter treatments. But how short is too short, considering the needs of people with personality-related difficulties and the challenges in developing a therapeutic relationship?

In this episode, Mike Crawford talks about a new study into a treatment of just 10 sessions using Structured Psychological Support, which draws on elements of DBT and MBT. We talk about the language used around personality disorder, how caution is now needed in reducing treatment duration, and about what to take forwards from this study for future treatment development.
