AI AND ETHICS

Man poisoned after following ChatGPT’s unsafe health advice

ChatGPT gave a man dangerous health advice that sent him to the hospital with hallucinations. It illustrates why you should never follow AI medical advice without consulting a doctor.

Details:

• The 60-year-old man asked ChatGPT for a healthy salt alternative. It told him to use sodium bromide, a toxic chemical.

• He took it for three months and started having extreme thirst, trouble walking, acne, paranoia, and both visual and hearing hallucinations.

• Doctors diagnosed him with bromism, a rare poisoning from too much bromide.

• He stayed in the hospital for three weeks, got fluids and medicine, and recovered fully.

Experts say AI can sound confident even when it is wrong, and using it for health advice without medical oversight can be dangerous.
