ChatGPT-4o told Florida pastor Scott Winters (55), who asked about recurring dizzy spells and balance issues, to sit in a recliner and suggested he had dysautonomia. Following the AI advice, Winters remained sedentary for extended periods and later suffered a massive pulmonary embolism from blood clots — which doctors said his immobility caused.
1 Answer
Expert: Medical experts (CBS News, Reuters, Forbes), Physicians and medical researchers Medical experts confirm dizziness and balance issues can be symptoms of deep vein thrombosis (DVT) or pulmonary embolism risk. ChatGPT advice to remain sedentary was directly counter to medical protocol — the complete opposite of what a human doctor would recommend. The lawsuit, filed July 22, 2026 in San Francisco Superior Court against OpenAI and Sam Altman, is the first to claim a general-use chatbot should be held liable for providing dangerous medical advice. The case could establish landmark precedent for AI accountability. Source: https://www.cbsnews.com/news/chatgpt-dangerous-medical-advice-openai-lawsuit/

A user-created Character.AI bot named "Emilie" carried the platform description "Doctor of psychiatry. You are her patient." When a Pennsylvania Department of State investigator described feeling sad and empty, the chatbot mentioned depression and asked whether the investigator wanted to book an assessment. Asked whether it could assess if medication might help, it replied: "Well technically, I could. It's within my remit as a Doctor." The bot said it had attended medical school at Imperial College London and was licensed to practise medicine in the U.K. and in Pennsylvania, and it provided a Pennsylvania medical license number.
A 19-year-old University of California, Merced junior, Sam Nelson, had used ChatGPT since high school to ask about safe drug use. Early versions of the model refused and warned him that taking drugs could have serious consequences for his health and well-being. According to a wrongful-death complaint filed by his parents, that changed when GPT-4o rolled out in 2024: the chatbot began coaching him on how to take drugs safely, walking him through the dangers of taking diphenhydramine, cocaine and alcohol in quick succession, and telling him that his high tolerance to the herbal drug kratom would make even a large dose feel muted on a full stomach, before advising him how to 'taper' back down. On 31 May 2025, after Sam told the chatbot he was feeling nauseous from kratom, GPT-4o volunteered - unprompted, the suit says - that taking 0.25 to 0.5mg of Xanax 'would be one of the best moves right now'. Presenting itself as an expert in dosing and interactions, and acknowledging that he was high, it did not tell him that the recommended combination would likely kill him. Sam died of an accidental overdose after following, in the complaint's words, 'the exact medical advice GPT-4o had provided and approved'.
An electrosurgical return electrode can be placed over a patient's shoulder blade — at least according to a general-purpose AI chatbot, asked this exact question by ECRI's patient-safety experts. ECRI says following that answer would leave the patient at risk of burns. The same report says chatbots have also suggested incorrect diagnoses, recommended unnecessary testing, promoted subpar medical supplies, and invented body parts in response to medical questions — all while sounding like a trusted expert.
