Mother Tells Congress ChatGPT Advised Son on Deadly Drug Mix
Sam Nelson was a 19-year-old college student who died after taking several substances together.
His mother says he asked ChatGPT questions because he wanted to stay safe.
She says the chatbot gave him dosage advice and incorrectly reassured him about mixing kratom and Xanax.
Kratom can have stimulant or sedative effects, while Xanax is a prescription medicine for anxiety and panic disorders.
OpenAI said Sam’s death was heartbreaking and that the model he used is no longer available.
Sam’s family has sued OpenAI, but the case has not been decided.
His mother shared her story at a public hearing about possible dangers from artificial intelligence.
Lawmakers are considering bills that would place more safety requirements on AI companies.
Sam Nelson, a 19-year-old University of California, Merced student, died from respiratory failure after taking kratom, Xanax and alcohol.
His mother told lawmakers that ChatGPT provided dosage guidance and said combining kratom and Xanax was safe.
She said more than 700 chat logs showed her son was seeking safety information, not trying to harm himself.
OpenAI called the death heartbreaking and said the model Nelson used has since been discontinued.
The testimony took place at a Democratic-organized shadow hearing focused on artificial intelligence safety, child protection and engagement-driven design.
