A 25-year-old white male died after consuming herbal extracts containing beta-carbolines and hallucinogenic tryptamines. Autopsy found no anatomic cause of death. Toxicologic analysis of heart blood identified N,N-dimethyltryptamine (0.02 mg/L), 5-methoxy-N,N-dimethyltryptamine (1.88 mg/L), tetrahydroharmine (0.38 mg/L), harmaline (0.07 mg/L), and harmine (0.17 mg/L). The medical examiner ruled the cause of death as hallucinogenic amine intoxication and the manner of death as undetermined.
Auditory perceptual biases, such as a tendency to hear things differently, are linked to anomalous self-experiences, especially feeling alienated from one's surroundings and emotional numbing, in people with first episode psychosis and healthy controls. No link was found between metacognitive efficiency and anomalous experiences. The findings support the minimal self-disturbance model of schizophrenia spectrum vulnerability, particularly the idea of hyperreflexivity.
