A gas chromatographic-mass spectrometric determination of the plasma N,N-dimethyltryptamine concentration from normals and psychiatric patients revealed that within the limit of sensitivity of the assay (0.5–1.8 ng/ml of plasma), there was no difference amongst normals, patients with psychotic depression, acute and chronic schizophrenia.
