Poisonings resulting from the ingestion of magic mushrooms in Kraków.

Hallucinogenic mushrooms, also called "magic mushrooms", are becoming a more frequent cause of abuse, especially among young people, who use them experimentally for recreational purposes. In the autumn of 2004, several people were admitted to and observed in the Department of Clinical Toxicology in Krakòw after they had used magic mushrooms to experience hallucinatory sensations. Three of them had visual hallucinations, and the fourth experienced both visual and auditory hallucinations followed by the exogenous psychosis after use of Psilocybe semilanceata. One person was hospitalised for several days while the others were observed in the emergency department. The main source of information for patients about hallucinogenic mushrooms was the internet. In the cases discussed the mushroom poisoning caused no organ damage and the symptoms disappeared in about 6 hours.
