The EEG was recorded continuously, and THC-induced psychopathology was assessed by pre- and post-experiment questionnaires. Subjects had to signal THC experiences. EEG measurements (distribution means of frequency bands derived from EEG frequency analysis)...
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...

The altered states of consciousness and the somatic changes were measured by several questionnaires administered after the experiment.
