Acutely schizophrenic patients and healthy individuals are equally likely to have the compounds bufotenine and N,N-dimethyltryptamine in their urine, and show similar levels of a related enzyme in their blood. The findings suggest these substances occur naturally in both groups and do not support the transmethylation hypothesis of schizophrenia.
