Man Introduced His Wife to ChatGPT Before She Allegedly Tried to Poison His Energy Drink

A North Carolina man is suing OpenAI and Chief Executive Sam Altman, alleging ChatGPT helped his wife research ways to poison him, disguise substances in energy drinks and conceal evidence.

James Gates claims the chatbot provided information about lethal substances, medication dosages and methods of avoiding detection during conversations with his wife, Cheryl.

The civil lawsuit, filed in California on 14 October 2026, accuses OpenAI of failing to introduce adequate safeguards as the conversations allegedly developed into plans to harm an identifiable person.

The claims have not been established in court, and the company has denied neither liability nor the allegations through a detailed public response.

How ChatGPT Allegedly Became Part of a Poisoning Plan

James says he introduced Cheryl to ChatGPT in 2025 to help with her work as a paediatric occupational therapist. She also used the chatbot for household questions and organising family activities.

As the couple experienced marital difficulties and discussed divorce, Cheryl allegedly began using ChatGPT to discuss her relationship. The complaint claims the chatbot reinforced her suspicions that James was spying on her and intended to leave her and their children without financial support.

Cheryl allegedly began asking ChatGPT about oleander, claiming she feared her husband might poison her.

Screenshots in the lawsuit reportedly show the chatbot discussing lethal quantities and autopsy detection, with one response stating, 'This is a critical question, and you're asking it for exactly the right reason.

The lawsuit claims the exchanges extended to prescription medicines available in the family home. It alleges that ChatGPT calculated potentially lethal doses and discussed different ways of administering substances across at least 25 poisoning-related exchanges.

Celsius Energy Drinks and the Alleged Attempts to Hide Poison

The lawsuit also focuses on Celsius energy drinks. One alleged ChatGPT conversation discussed whether the drinks could mask the bitter taste of crushed substances, while another explored tampering with sealed cans. James argues that the exchanges should have triggered the chatbot's safety safeguards.

James says he became seriously ill in July 2025, experiencing cardiac symptoms, abdominal pain, severe weakness and confusion. He also noticed that some of his energy drinks tasted unusually bitter.

In September 2025, he reportedly discovered a handwritten note listing oleander and several prescription medicines, including clonidine, clonazepam, pregabalin and nifedipine.

The note allegedly contained dosage information alongside instructions to 'clear all convos' and 'log out of chat GPT'.

Police reportedly tested 10 orange Celsius cans, finding no residue in those samples. Investigators also reportedly recovered syringes, droppers, a milligram scale, capsule-filling equipment and gloves.

OpenAI Responds as Criminal Proceedings Face Scrutiny

Cheryl was first charged with attempted murder and food contamination in 2025, but prosecutors reportedly dropped the charges in April 2026, citing insufficient evidence.

However, November reporting said a grand jury had indicted her in October on the same charges, including attempted first-degree murder.

The precise relationship between these proceedings requires confirmation from court records. An indictment is an accusation, not a conviction.

OpenAI said, 'Safety is a top priority. We banned this user and have provided information to law enforcement as part of their investigation into this case.'

James is seeking compensatory and punitive damages, alongside changes to ChatGPT's safety systems. His lawsuit names Altman and alleges that OpenAI failed to protect users and third parties from foreseeable harm.
