A new review from neuroethicist Eddie Jacobs, and published in the Journal of Psychedelic Studies, is suggesting psilocybin may have great potential as a treatment for obsessive-compulsive disorder (OCD). Jacobs, from King’s College London and the University of Oxford, says it is surprising how little focus has been on the therapeutic potential of psilocybin in treating OCD, and he points to a number of new clinical trials that are finally exploring this promising treatment.
