In conclusion, Sorcha discusses the protocol for the PsilOCD study at Imperial College London, with results from this study soon to be published.

“[OCD] is this complex behavioral pattern and certain medications moderately help and nothing seems to be highly effective yet and that definitely points to the need for novel pharmacotherapy.” [12:46]
“[By utilizing lower doses of psilocybin], people who maybe fixate on their health and on their mental health and sensations and things can benefit from psilocybin without having to overcome that barrier.” [18:25]
