>They gave psilocybin in much lower dose to the placebo group... I wonder what the point of that was Psylocybin usually comes with obvious hallucinogenic or physiological effects. The placebo group would instantly realize they have been given a placebo if no physiological effects appear at all, hereby making the blind study useless. The Charité hospital in Berlin is starting a similar study sometime in summer of this year. The setup is that the control/placebo group (instead of Psylocybin) receives a dosage of Niacin [1]. This causes a "flushing" effect[2] in the test subject and in this way can trick them into believing they have indeed received Psylocybin.
