Seminar: Robin M Murray
Professor Sir Robin M Murray is a Scottish psychiatrist, at the Institute of Psychiatry, King's College London. In 1987 he was among the first to suggest that schizophrenia might be a neurodevelopmental disorder. Together with colleagues, he has demonstrated the important role of environmental factors in the etiology of schizophrenia including obstetric and other early childhood events. Robin Murray and colleagues were among the first to demonstrate that prolonged heavy abuse of cannabis can contribute to the onset of psychosis, and that starting early before 15 years and using high potency cannabis (e.g. skunk) particularly increase the risk. Currently, they are researching why some people are especially vulnerable to this drug while most develop no problems. Murray previously wrote that while the risk increase is "about five-fold [...] for the heaviest users", the issue has become a political football. Murray has commented repeatedly on these issues in BBC articles and programmes.
