Amid today’s psychedelic renaissance, more IRBs will find themselves responsible for oversight of psychedelic research. In this gatekeeping role, IRBs must ensure appropriate participant protection without inhibiting important science. Yet neither IRB perspectives on psychedelic research nor psychedelic investigator experiences with IRBs have been studied. Through interviews with psychedelic investigators and a survey of IRB chairpersons, Prof. Lynch's project aims to promote high-quality ethics review of psychedelic research by developing empirically informed resources for both IRBs and investigators.
