The Medicine May Prepare the Soil. Integration is the Work that Makes it Grow.

When my daughters were young, one of the books we returned to again and again was Frog and Toad. One story, The Garden, has stayed with me ever since. At the time it felt like a gentle lesson in patience. Years later, working as a medical doctor in psychiatry and supporting people in legal psilocybin retreats, I realized it also describes the process of psychological and behavioral change related to psychedelics quite well.

Gardens cannot be rushed. You prepare the soil, plant the seed and return to it with care. Most of the important work happens beneath the surface, long before anything becomes visible. And everyone who has worked a garden knows it is tedious and sweaty at times.

Much of today’s conversation about ketamine, psilocybin and other psychedelics centres on pharmacology. Those questions matter. Ketamine can produce rapid antidepressant effects in treatment-resistant depression. Psilocybin as well has shown durable antidepressant benefits for some people after one or two dosing sessions. Ibogaine has shown promise in addiction treatment with anti-craving and antidepressant effects. Different psychedelic medicines, different mechanisms, different evidence—but they all point toward the same possibility: a temporary biological window in which psychological change may become more accessible.

Over the years I have noticed that the sessions people remember most are not always the most dramatic. More often, they are the ones that quietly changed what happened afterwards: a difficult conversation finally took place, a relationship began to heal, avoidance gave way to curiosity, or a healthier routine slowly became sustainable. The experience mattered. What transformed life was what followed.

The same impression emerged in our qualitative study of adolescents’ psychedelic experiences, currently under review. Participants often described the experience as the beginning rather than the destination. Its meaning continued to evolve through conversations, relationships and everyday choices. Some wished they had received more guidance and integration support afterwards; others found their own way. Integration looked different for each person.

That is why I increasingly think of augmentation with psychedelics or other non-pharmacological methods such as breathwork as preparing the soil. The medicine may due to its biological effects loosen rigid patterns, increase psychological flexibility and allow people to encounter themselves from a different perspective. Powerful as that is, it remains an opportunity rather than a guarantee.

Preparation therefore begins long before any medicine is administered. It starts by understanding the individual: their psychiatric and medical history, relationships, values, hopes and vulnerabilities. Safety is fundamental, but preparation is also about intention. What kind of life does this person hope to cultivate? Which habits move them towards it, and which repeatedly pull them away?

Integration is often described as talking about the experience. I think it is something simpler and more demanding. It is deciding what deserves to become part of everyday life. For some people that process requires psychotherapy. Others benefit from behavioural activation, movement, mindfulness, trusted relationships or simply time. Like psychotherapy itself, integration should be personalized. As my mentor professor JoAnne Dahl said in an email conversation a while ago, integration is the reality of Life.

No therapist can grow someone else’s garden. We can offer knowledge, structure, accountability and compassion, but eventually the healthier boundary, the morning walk and the difficult conversation belong to the individual. Lasting change is built through repeated actions, not profound moments alone.

Recent international consensus papers have highlighted preparation, psychological support and integration as essential elements of psychedelic-assisted therapies while acknowledging how much remains unknown. We still do not know which models work best for whom, how much support is optimal or how these elements contribute to outcomes. Those questions represent one of the field’s most exciting opportunities.

At Nūvai, we see preparation and integration as integral to treatment rather than administrative steps around it to ensure safety. We are deliberately building a culture of careful attention to detail, presence, compassion and genuine curiosity. Every interaction matters—from the first phone call to the final follow-up—because trust is built through small moments as much as extraordinary ones.

Our ambition extends beyond delivering ketamine-assisted psychotherapy. We hope to help shape the future of preparation and integration by combining psychotherapy, behavioural science, physiology, longitudinal outcome monitoring and digital tools that support change between sessions. We do not claim to have all the answers. We want to help discover them.

The future of psychedelic therapy will not be defined only by better molecules. It will also be defined by better preparation, better integration and a deeper understanding of the individual differences in how people transform meaningful experiences into everyday life. The medicine may prepare the soil. What grows afterwards depends on how we care for the garden.
