Who Diego Quattrone is

Dr Diego Quattrone is a Consultant Psychiatrist at the Maudsley Hospital and runs the Johnson Psychiatric Intensive Care Unit (PICU), located at the Ladywell Unit, University Hospital Lewisham, which specialises in delivering comprehensive care to patients in the most acute stages of their psychiatric illness. He has previously led the Inpatient and Crisis Services for the Lewisham Operations Directorate of South London and Maudsley NHS Foundation Trust. He holds a Senior Lecturer position at King's College London and is an Associate Professor of Psychiatry at the University of Palermo. His research focuses on the epidemiology and genetics of psychopathology associated with cannabis use and addiction, including the role of the endocannabinoid system in psychosis risk. In UK press coverage he has argued that cannabis use is heavily implicated in acute psychiatric admissions, reporting that at least 80% of new patients at his PICU disclose cannabis use, and that the risks of the drug are frequently underestimated.

“at least 80% of new admissions report cannabis use. He feels the dangers of the drug are overlooked, adding that use is "among the strongest factors associated with violence before and during admission"”
