A healthy 18-year-old woman developed severe anxiety, hallucinations, and physical agitation after ingesting a mushroom product bought at a gas station. Doctors diagnosed psilocybin intoxication based on her symptoms and their resolution with supportive care, despite not having confirmatory toxicology tests. The product's vague labeling made diagnosis challenging. She was treated with intravenous fluids and benzodiazepines, and her symptoms gradually resolved before discharge. This case illustrates how commercially available mushroom products can cause hallucinogen intoxication, requiring clinicians to rely on clinical signs and careful exclusion of other causes.
