Yale Psychedelic Science Group

With the recent re-emergence of psychedelic research demonstrating therapeutic efficacy for a variety of psychiatric and medical conditions, a small group of residents, fellows, and faculty at Yale that initially met informally to discuss current research recognized the need for a more structured educational initiative to illuminate this important and rapidly growing area of science. The Yale Psychedelic Science Group (YPSG) was established in January 2016 as an interest group within the Yale Department of Psychiatry to discuss issues at the intersection of psychedelic substances and psychiatry.

Although the YPSG hopes to enlarge the scope of its discussion and activities, its initial focus will be on contemporary clinical research and the mechanisms of action of psychedelic treatments. Therefore the YPSG has organized a forum where clinicians and scholars from across Yale can learn about and discuss the recent studies in an academically rigorous manner. At our monthly meetings, research scientists from outside institutions who are activity engaged in clinical studies with classical psychedelic compounds present their findings. The primary objectives of this forum are to promote a critical examination of the presented work and to encourage the sharing of interdisciplinary perspectives during the ensuing discussion period.
