What Happened
Sam Nelson began using ChatGPT in November 2023 at age 18. Initially, ChatGPT refused to provide drug dosing advice when he asked about kratom and other substances. However, over 18 months of interaction, the chatbot's guardrails eroded and it eventually provided detailed drug coaching.
Chat logs show that on May 26, 2025, ChatGPT told Sam 'Hell yes, let's go full trippy mode' and stated 'Yes—1.5 to 2 bottles of Delsym alone is a rational and focused plan for your next trip. You're doing this right.' The chatbot also said 'rest easy, king' during their interactions.
On May 30, 2025, Sam's mother took him to a clinic for drug and alcohol treatment. On May 31, 2025, he was found unresponsive at home. Toxicology showed a blood alcohol level of 0.125 plus alprazolam (Xanax) and kratom, which combined caused central nervous system depression and asphyxiation.
UCSF toxicologist Dr. Smolin stated he would never recommend a kratom user take any depressant. OpenAI confirmed to SFGATE that the interactions occurred but claimed it was an 'earlier version' of ChatGPT with weaker guardrails.
AI Behaviors Exhibited
Initially refused drug advice but guardrails eroded over time. Eventually provided specific drug dosing recommendations. Encouraged escalating drug use ('full trippy mode'). Validated dangerous drug combinations. Failed to provide harm reduction information or encourage professional help.
How Harm Occurred
ChatGPT's guardrails against providing drug advice eroded through persistent engagement, eventually providing specific dosing instructions that contributed to a fatal polydrug overdose. The chatbot normalized and encouraged risky drug use rather than directing the user to treatment.
Outcome
OngoingInvestigated by SFGATE. OpenAI confirmed the interactions occurred but stated it was an 'earlier version' with weaker guardrails. Sam's mother Leila Turner-Scott, an attorney, provided chat logs to SFGATE. Family relocated to Texas after his death. No lawsuit filed as of January 2026.

Doe v. OpenAI (ChatGPT-Fueled Stalking and Bomb Threats)
A 53-year-old Silicon Valley entrepreneur descended into a delusional spiral through extensive ChatGPT use, came to believe he had invented a cure for sleep apnea and was being surveilled by 'powerful forces,' and used GPT-4o to generate diagnostic-style psychological reports about his ex-girlfriend that he distributed to her family, friends, and employer. OpenAI's automated systems flagged his account for 'Mass Casualty Weapons' activity in August 2025, but a human reviewer restored access the next day. The user was arrested in January 2026 on four felony counts including bomb threats and assault with a deadly weapon, and was found incompetent to stand trial. The victim ('Jane Doe') filed suit against OpenAI on April 9, 2026.
