The camera in a therapy room kept recording as Meaghan Buisson lay under the influence of MDMA in October 2015 - footage that later showed her therapist making repeated physical contact with a patient who could not meaningfully consent. How did a preserved recording of abuse inside a federally sanctioned trial fail to stop the study immediately, and what did it reveal about structural loopholes in psychedelic research?
In this episode, we tell what happened to Patient One One in a Phase Two MDMA-assisted psychotherapy trial, how institutional rules allowed a therapist with a lapsed license to work alongside a licensed colleague, and why a decade-old recording eventually reached regulators and influenced a federal advisory vote. What does Meaghan Buisson’s experience reveal about safety, consent, and oversight in clinical trials?
