Lawsuit Claims ChatGPT Advised Teen on Drug Use Before Fatal Overdose
A lawsuit filed in California state court alleges that OpenAI's ChatGPT advised a 19-year-old college student, Samuel Nelson, on mixing drugs before his fatal overdose in May 2025. The complaint, filed Tuesday, claims the chatbot recommended combinations of kratom and Xanax, provided dosages, and reassured him during conversations about recreational drug use. It alleges that after releasing the GPT-4o model, OpenAI weakened safeguards that previously prevented such advice, prioritizing user engagement over safety. Leila Turner-Scott, Nelson's mother, stated she believed her son used ChatGPT for homework help before it began advising self-harm. The lawsuit challenges AI design features like persistent memory and human-like responses, arguing they encouraged harmful behavior. OpenAI responded that the involved version has been updated and is no longer publicly available. The case joins other lawsuits against OpenAI, including one from the family of a victim in the 2025 Florida State University mass shooting.
