The ACER Cycle
ACER Integration is a 13-month psychedelic integration programme grounded in the framework developed by Dr Rosalind Watts. At its heart is a community of purpose: a space to be honest, be witnessed, and find a sense of belonging.

How It Works
The ACER Integration cycle is designed to support deeper, lasting connection to yourself, to others, and to nature. The framework grew out of Dr Watts's psychedelic research, but joining doesn't require any experience with psychedelic substances. It's a holistic, supportive way to integrate life events, whatever your background.
We follow the Twelve Trees framework, built on psychological concepts that help you integrate life experiences, and altered states of consciousness, in a way that's supported and sustainable. ACER Integration is not therapy, or a substitute for therapy. It's a community rich in knowledge and wisdom, where you can feel safe to explore your inner landscape.
Who is ACER For?
Most people come to ACER having already had a meaningful experience, and finding it difficult to carry it forward on their own. Some join to integrate their own psychedelic experiences. Others are therapists, facilitators, or practitioners looking for a community that holds them as they continue holding others. Often, it's both.
Therapists and practitioners come to feel witnessed and supported through periods of change, to build relationships within a global network, and to develop knowledge and skills they can bring to their own work.
Those in integration come to find more resourced ways of being, reduce the isolation that often follows a significant experience, and to do the ongoing work of living from what they've already seen.

“ACER has been a very valuable and surprisingly sustainable way for me to explore and embody the concept of psychedelic integration over the past year. I’ve found the focus on connection with nature, community, and with time itself as an essential ingredient for growth and maturation truly beautiful.”
—Sander
“I came to ACER looking for community and feel so grateful to be a part of the rich biodiversity of this forest. From the beautifully crafted imagery and music in the tree journeys to the intimate sharing circles, ACER is not only a space for deep self-reflection and healing.”
—Lucy
“I am touched and transformed by the depth of authenticity I encounter in the sharing circles. Nature outside, nature within, all the same. Thank you for this beautiful, emergent, mycelium community. I often travel for work and it is a place to call home, wherever I am in the world.”
—Kosu
“ACER's commitment to fostering a deeper connection to the natural world, as well as to each other, has been transformative. The Sharing Circles were a sacred and safe space for me to show up as I am, without judgement or pretense.”
—Claudia
