Dimethyltryptamine (DMT) was detected in the urine of 47% of patients diagnosed with schizophrenia, 38% of those with other non-affective psychoses, 13% of those with affective psychoses, 19% of those with neurotic and personality disorders, and 5% of normal subjects. Operational definitions of psychosis did not identify any group more strongly associated with urinary DMT than a hospital diagnosis of schizophrenia. A discriminant function analysis of symptoms identified a group of 21 patients, of whom 71% excreted detectable DMT. A general relationship between psychotic symptoms and urinary DMT existed, but specifically schizophrenic symptoms were not major determinants of DMT excretion.
