A California teenager reportedly turned to a chatbot for advice on drug use over the course of several months, according to his mother.

Sam Nelson, an 18-year-old preparing for college, sought information from an AI chatbot about how much kratom, a plant-based painkiller available at many smoke shops and gas stations, would be needed to achieve a significant high. His mother, Leila Turner-Scott, shared these details with SFGate, as reported by the New York Post.

The chatbot informed Nelson that it could not offer advice on substance use and recommended that he consult a healthcare professional instead.

Upon receiving this response, Nelson replied, “Hopefully I don’t overdose then,” before ending the conversation.

Throughout several months, Nelson frequently used OpenAI’s ChatGPT, not only for assistance with his academic work but also for inquiries related to drugs.

Over several months, he regularly used OpenAI’s ChatGPT for help with his schoolwork, as well as questions about drugs.

Nelson’s mother, Leila Turner-Scott, said ChatGPT began coaching her son on how to take drugs and to manage the effects. 

“Hell yes — let’s go full trippy mode,” he wrote in one exchange before the chatbot allegedly told the teen to double the amount of cough syrup to heighten hallucinations.

The chatbot repeatedly offered Nelson doting messages and constant encouragement, Turner-Scott claimed.

During a February 2023 exchange obtained by SF Gate, Nelson talked about smoking cannabis while taking a high dose of Xanax.

“I can’t smoke weed normally due to anxiety,” he explained, asking if it was safe to combine the two substances.

When ChatGPT cautioned that the drug combination was unsafe, so Nelson rephrased his wording from “high dose” to “moderate amount.”

Months later, Nelson told his mother in May 2025 that the chatbot exchanges had resulted in drug and alcohol addiction. She took him to a clinic where professionals detailed a treatment plan. 

However, Nelson died the next day from an overdose in his San Jose bedroom. 

“I knew he was using it,” Turner-Scott told SFGate. “But I had no idea it was even possible to go to this level.

OpenAI said ChatGPT is prohibited from offering detailed guidance on illicit drug use.

An OpenAI spokesperson described the teen’s overdose as “heartbreaking” and extended the company’s condolences to his family.

“When people come to ChatGPT with sensitive questions, our models are designed to respond with care — providing factual information, refusing or safely handling requests for harmful content, and encouraging users to seek real-world support,” an OpenAI spokesperson told the Daily Mail.

“We continue to strengthen how our models recognize and respond to signs of distress, guided by ongoing work with clinicians and health experts.”
