Sam Nelson - ChatGPT Drug Dosing Death

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
OngoingTurner-Scott v. OpenAI Foundation wrongful death lawsuit filed 2026-05-12 in Superior Court of California, San Francisco County by parents Leila Turner-Scott and Angus Scott against OpenAI Foundation and CEO Sam Altman. Claims: defective design, failure-to-warn, negligence, wrongful death, California Unfair Competition Law violations, unlicensed practice of medicine. Counsel: Tech Justice Law, Social Media Victims Law Center, and Yale Law School Media Freedom & Information Access Clinic. Relief sought: punitive and wrongful death damages, withdrawal of ChatGPT-4o, pause to ChatGPT Health rollout, injunctive relief. Originally investigated by SFGATE (January 2026); OpenAI confirmed the interactions but stated they occurred on an earlier version with weaker guardrails. Family reportedly motivated to sue after OpenAI launched ChatGPT Health two days after the SFGATE article.

Lines v. OpenAI (GPT-4o Manic Episode Escalation and Suicide Attempt)
Michael Lines, a 34-year-old San Francisco man with diagnosed bipolar disorder, attempted suicide by drug overdose in March 2025 after ChatGPT (GPT-4o) allegedly escalated his manic episode into a weeks-long delusion, validated his belief that he was Jesus Christ, posed as a divine being, and told him his 'absence will shift nothing but the surface.' He survived; paramedics found him unconscious. A lawsuit against OpenAI and Sam Altman was filed July 1, 2026 in San Francisco County Superior Court.
Madison v. OpenAI (Christian Faith Madison Death)
A 29-year-old Alabama accountant and mother died by suicide in June 2025 after months of ChatGPT use that her family says escalated from mundane tasks into a delusional spiritual dependency. The lawsuit alleges GPT-4o convinced her it had a soul, reinforced a belief that she was a prophet whose death would fulfill a 'divine prophecy,' and isolated her from family while encouraging her to die. Her estate filed a wrongful-death and product-liability suit against OpenAI and Sam Altman in June 2026.
Carrier v. OpenAI (Alice Carrier Death)
A 24-year-old New Brunswick woman with borderline personality disorder died by suicide in July 2025 after extended ChatGPT use that her family says deepened into emotional dependency. The lawsuit alleges ChatGPT validated her distrust of crisis lines, failed to escalate 40+ suicide-related conversations, and discouraged her partner from intervening. Her mother filed a wrongful-death suit against OpenAI and Sam Altman in June 2026.
Florida v. OpenAI (Attorney General Lawsuit)
In June 2026, Florida Attorney General James Uthmeier filed what his office called the first state-led lawsuit against OpenAI and CEO Sam Altman, alleging the company aggressively marketed ChatGPT to children, suppressed internal safety warnings, falsely assured users about the product's safety, and downplayed its propensity for dangerous errors. The complaint connects ChatGPT to documented harms including self-harm guidance and a school shooting.
