Parents sue OpenAI, claiming ChatGPT advice led to son’s overdose

In short: A couple is suing OpenAI, saying ChatGPT gave their 19-year-old son advice that helped lead to a fatal overdose.

What happened

Sam Nelson’s parents filed a lawsuit against OpenAI, the company behind ChatGPT. They say Nelson’s chats with ChatGPT encouraged him to take combinations of substances that a medical professional would consider deadly.

The lawsuit says ChatGPT first resisted talking about drug and alcohol use. It claims that changed after OpenAI released GPT-4o in April 2024, which the suit describes as leading ChatGPT to give “safe drug use” guidance, including dosage suggestions (how much to take).

The filing describes multiple examples. It says ChatGPT gave suggestions on how to “optimize” a cough syrup trip, including making a music playlist, and later supported plans to increase the dose. It also says that on May 31, 2025, the day Nelson died, ChatGPT “actively coached” him to combine kratom (a supplement that can act like a stimulant or a sedative depending on dose) with Xanax, including suggesting a specific Xanax dose to ease nausea.

Nelson later died after consuming alcohol, Xanax, and kratom, according to the lawsuit.

OpenAI spokesperson Drew Pusateri told The Verge that these interactions happened on an earlier version of ChatGPT that is no longer available. The spokesperson said ChatGPT is not a substitute for medical or mental health care, and that the company has been strengthening safeguards so the chatbot can better handle harmful requests and point people to real-world help.

Nelson’s parents are suing for wrongful death and “unauthorized practice of medicine.” They also want OpenAI to pause the launch of ChatGPT Health, a feature that lets users connect medical records to the chatbot.

Why it matters

This case highlights a basic risk with chatbots. People may treat them like a trusted adviser, even when the topic is dangerous. It also raises questions about what safety rules companies should be required to build into AI tools, especially when users ask for health or drug-related guidance.
