Most of Sunstone’s psychedelic-assisted therapy sessions occur one-on-one. One therapist stays with one participant through preparation, the dosing session, and integration afterward.
Some Sunstone studies bring participants together at points along the way.
In our first psilocybin trial, participants prepared as a group, received psilocybin at the same time in their own rooms with their own therapist beside them, and came back together to integrate.
Some arrived wary of groups and described a close bond by the end. They had two things in common: an experience that's hard to describe to anyone who hasn't had one, and a diagnosis most had been carrying privately.
One of those groups is still meeting years after the study closed.
We're studying how best to incorporate group therapy into psychedelic-assisted therapy, where it belongs in a study, and for whom it matters most.
