This retreat is aimed at mental health professionals interested in becoming psychedelic-assisted therapists, psychedelic therapists interested in an ACT-informed psychedelic experience and those wishing to better support people in integrating psychedelic experiences.

There is currently a psychedelic research renaissance involving sizeable clinical trials in both Europe and the USA. Even if preliminary, the current results suggest unprecedented success rates for depression, addictions and more. With such trials underway, psilocybin is expected be medically licenced in the next 5 years (See New Atlas FDA Breakthrough therapy, or Wired for more depth). The purpose of this retreat is to prepare and connect those interested in such developments. If you are interested in collaborating on future retreats like this, you are especially welcome.

Experts at multiple psychedelic research centres consider Acceptance and Commitment Therapy to be an important and useful framework for modern psychedelic therapy (see Walsh & Theissen 2018Guss 2018). These four and a half days are an opportunity to explore the psychedelic experience with some ACT perspectives in mind.

In preparation you may consider your personal challenges in terms of ‘willingness’ (how open are you to certain discomforts?), ‘experiential avoidance’ (what are the obvious or subtle ways you avoid those inner discomforts?), your motivations (what impulses behind your inner and outer behaviours are keeping you from what you truly want). Simple metaphors such as the ‘reverse compass’ may guide us on our way: where is your mind telling you not to go?

To integrate your psilocybin experience into a life better lived, we may also consider if our old thought patterns take us where we really want to go. What new behaviours do our insights invite? How might our old habits get in the way of what we really want?

As well as offering these latter perspectives, the ACT model also invites its own integration with other models and traditions, into a behaviourally aware eclecticism. Some of these modalities of integration include breathwork, art therapy, neuroplasticity and guided visualisation.

Participants are invited to contribute their data towards a multi-baseline, single case series design study, tracking mediators of change before and after a psychedelic-assisted personal growth, including a number of ACT preparation and integration sessions pre and post retreat. Please contact us for further details of this research project…

This four and a half day retreat will include:

Day 1: Arrival (in the afternoon) and preparation: approaching the psychedelic experience as an opportunity for personal growth
Day 2: Self as context meditation and bodywork – you are not your programming. Afternoon ceremony – with Psilocybin Truffles, you embark on your psychedelic journey with the support of sober mental health professionals
Day 3: Integration – What is still coming up? Being in your direct experiencing. Breathwork. Journaling on your experience as it continues to surface.
Day 4: Second Ceremony – an opportunity to go deeper.
Day 5: Further integration – Has any of your inner or outer behaviour changed? What might you continue to do differently? What new paths do you feel invited to follow? Current psychedelic integration research findings. Is a new view emerging of the kind of life you want to live? Late afternoon departure.

Each day will include experiential practices to help us get into our direct experiencing. Through sharing circles we will learn from each other.

Minimum facilitator ratio: one to every five participants. Each participant will receive one on one pre and post-ceremony check-ins.

Those participating in the study will receive two preparatory, and four post ceremony integration sessions at no additional cost.

Spaces are highly limited to a maximum of 15. Private rooms available for a supplementary fee of £150/night

This retreat will also have other mental health professionals with ACT training and psychedelic therapy guide experience, ensuring each of you can receive individual attention when you need it. This retreat is not aimed at people with severe mental-health issues. All facilitators will remain sober throughout the retreat.

Join us in our stunning location with hot tubs and acres of woodland to soothe you on your journey.
