North Carolina man sues OpenAI, alleging ChatGPT encouraged wife to poison him

The lawsuit

James Gates, of Charlotte, North Carolina, sued OpenAI in San Francisco Superior Court in October. The civil complaint alleges that ChatGPT gave his estranged wife, Cheryl Harris Gates, detailed instructions on how to poison him. The suit describes the chatbot as “defective” and says it “manipulated and encouraged” Harris Gates to poison her husband. Gates says he suffered severe physical and emotional harm and is seeking unspecified damages. The allegations in the lawsuit have not been proven in court.

What the suit alleges

According to the lawsuit, Harris Gates began using ChatGPT in early 2025 to assist with work evaluations while employed by Charlotte-Mecklenburg Schools. Her husband worked in cybersecurity. The suit says the couple’s marriage was under increasing strain, primarily driven by finances, and that they had discussed divorce but Gates had not contacted a divorce attorney.

The lawsuit alleges ChatGPT validated Harris Gates’ frustrations and began “feeding Cheryl’s increasing mistrust and delusions about her husband spying on her and planning to leave her and her kids with nothing.” Gates had told his wife he never intended to do that, the suit says.

The suit alleges that over several conversations, Harris Gates portrayed her husband as “narcissistic” and “controlling” and asked for details “about how to poison her husband, including what dosages and drugs to use and combine for his weight,” and how to conceal purchases from law enforcement.

Specific alleged exchanges include:

• Asking about the toxic plant oleander and how many leaves would be lethal, framed as self-protection. The suit alleges ChatGPT responded with specific instructions on preparation, dosage and administration, whether the plant would show up on an autopsy, and that its bitter taste could be masked in her husband’s energy drink.
• Asking if mixing Ambien and pregabalin “is better hidden in a beer at night or Celsius in the morning.” The suit alleges the chatbot said the energy drink would be better and made a table “rating which drinks best mask the taste of the poisons.”
• Asking which combinations and doses of drugs already in the home could be made lethal, and how to deliver them. The suit also alleges the chatbot named local places where she could anonymously buy castor beans, the main source of ricin.

The illness, arrest, and OpenAI’s response

Gates said he fell severely ill in July 2025 but recovered. His symptoms included a racing heart, extreme jitteriness and uncontrollable shaking, and he could not leave his couch for days, the suit says.

Harris Gates was arrested in October 2025 and charged with attempted murder and contaminating food or drink with a controlled substance. The district attorney’s office later dropped the charges for lack of evidence. An attorney for Harris Gates declined to comment.

Gates told USA Today that his wife moved in August 2025. He said he found a handwritten note after she came to pick up her belongings and left a notebook on the kitchen counter; the paper fell out when he picked it up. The note referred to the plan and included a reminder to delete her ChatGPT history, the lawsuit says.

The suit alleges Harris Gates’ Amazon history showed searches for syringes, and that liquid droppers, syringes, a scale and gloves were found at the home during a police search. It also accuses ChatGPT of prompting her to delete her chat history so it cannot be accessed, even if subpoenaed.

An OpenAI spokesperson said “safety is a top priority” and that Harris Gates was banned from the platform. The company said it works with mental health experts to help ChatGPT recognize signs of distress and to expand access to localized crisis resources and hotlines.

Gates told USA Today that he is separated from his wife and has temporary custody of the children.

Why it matters

The case is one of the first major civil lawsuits alleging that an AI chatbot provided instructions for a violent crime. It raises questions about how AI systems handle requests involving self-harm, violence, and dangerous substances, and whether companies can be held liable when users allege a chatbot encouraged illegal acts. OpenAI has said safety is a top priority and that it works with mental health experts to help ChatGPT recognize signs of distress.
