[Effects of N,N-dimethyltryptamine (DMT) on tests of psychoticism (author's transl)].

In a controlled study on 38 volunteers the effects of 250 micrograms/kg N,N-dimethyltryptamine (DMT) i.m. on objective and performance tests measuring psychoticism according to Eysenck were assessed. The hypothesis was tested that subjects treated with DMT (N = 26) differ from those receiving placebo (N = 12) in the same way as endogenous psychotics differ from normals. Confirmation was obtained in 7 out of 19 variables, most of which may be considered as tests of concentration. These results are similar to those of a previous study on the effects of (-) delta9-trans-Tetrahydrocannabinol.
