Dr Marta Di Forti is a Senior Lecturer at the Dept of Social, Developmental and Genetic Research, Institute of Psychiatry, and Honorary Consultant Adult Psychiatrist, Lambeth Community team, South London and Maudsley NHS foundation Trust. She leads the first and only Cannabis Clinic for patients with Psychotic disorders in UK. She was recently awarded a MRC Senior Research Fellowship to expand her research in the role of cannabis use in psychosis and its underlying biology. With her team she showed for the first time that use of high potency types of cannabis e.g. "skunk" carries a higher risk of psychosis than use of traditional types and that it affects rates of Psychotic disorders across Europe. Though it still remains unclear who are those cannabis use most at risk. Her future work aims to investigate the interaction between cannabis use and genes predisposing to schizophrenia, and how cannabis changes the epigenome.
