A 41-year-old man seeking the meaning of life drank a tea and paste made from the San Pedro cactus during a shamanic ritual. Hallucinations began after 9.5 hours, presenting as a psychotic reaction with catatonia. He was admitted to a psychiatry department and given a second-generation antipsychotic. The clinical symptoms resolved about 60 hours after mescaline ingestion, attributed to the antipsychotic's antagonistic effect on serotoninergic 5-HT2A receptors.
