As Clinical Lead of the Psilocybin for Depression Study at Imperial College London and Clinical Director of Synthesis Institute Dr. Rosalind Watts recognized the potential of psychedelic therapy, but also its risks and pitfalls, namely that the psychedelic substance can open the door, but real, long-lasting benefits depend on substantial integration support. She is the founder and director of Twelve Trees Integration, a global community with online and in-person aspects to support people in the months and years after their psychedelic experiences. Twelve Trees focuses on helping people build their connectedness to self, others, and the natural world. This is the mechanism that Dr. Watts discovered to be underpinning the changes observed in her psilocybin for depression research, leading her to develop a model for psychedelic therapy, "Accept, Connect, Embody (ACE)," a model for community integration of psychedelic work, "Accept, Connect, Embody, Restore (ACER)," and a psychometric tool for measuring connectedness (Watts Connectedness Scale (WCS). Dr. Watts co-founded the UK's first psychedelic integration group, sits on advisory boards for The Usona Institute and The Synthesis Institute, and is a consultant psychologist for small pharma that are investigating DMT as a treatment for depression.
