An inquest heard that Joshua Warner, a 21-year-old first-year psychology student at the University of Portsmouth, died by suicide in January 2023 after obtaining a lethal substance online from Canadian seller Kenneth Law. The coroner concluded that Mr Warner had intended to end his life and that his death could not reasonably have been predicted or prevented by the health professionals treating him, despite his family’s concerns about access to care.

Law has pleaded guilty in Canada to aiding and abetting suicide and is due to be sentenced, with Mr Warner’s case to be added to the proceedings. The National Crime Agency said Law sent 330 products to the UK that were directly linked to 79 deaths, while Mr Warner’s family described him as a thoughtful, witty and deeply loved young man who had struggled privately with borderline personality disorder, ADHD and depression.
