Integration therapy

Not to be confused with sensory integration therapy, an unrelated occupational-therapy approach for sensory-processing difficulties (for example, in autism) — this page covers psychedelic integration therapy specifically.

What is psychedelic integration?

Psychedelic integration is the process of making sense of a psychedelic experience and translating it into lasting change in daily life. It is not a single session — it is an ongoing practice, typically spanning weeks to months, supported by a trained therapist. The term covers both the preparatory work before a session and the reflective work afterward.

"Integration" in a psychedelic-therapy context means the non-drug psychological work that prepares a patient for a session and helps them metabolize the experience afterward. It is done by a licensed mental-health professional — psychologist, psychiatrist, licensed clinical social worker, licensed professional counselor, marriage and family therapist — with training in how psychedelic experiences interact with psychotherapy.

It is not:

• A substitute for medical supervision during dosing.
• The same thing as psychedelic-assisted therapy (PAT), which involves the therapist being present during the dosing session.
• Coaching or "guiding" without a clinical license — a large and unregulated market that does not meet the professional standards described on this page.

The distinction matters legally and clinically. For legally accessible therapies (ketamine, Oregon/Colorado psilocybin), patients typically see two professionals: a medical prescriber or facilitator who handles the dose, and a separate licensed therapist who handles the before-and-after. For therapies accessed through trials or retreats abroad, finding a qualified integration therapist at home is often the most impactful preparation a patient can do.

Why integration matters (the evidence)

The 2025 meta-analysis

The most systematic look at this question, published in JAMA Psychiatry in 2025, synthesized 12 controlled trials of psychedelic-assisted therapy for depression (733 participants total, classic psychedelics only). The authors ran metaregressions on preparation hours, integration hours, and total session count.¹

• Overall effect of PAT on depressive symptoms: Hedges g = -0.84 (large, clinically meaningful).
• Preparation hours were significantly associated with greater symptom reduction (β = -0.13; p = 0.04).
• Post-dose integration hours were not statistically associated with outcome (p = 0.53).
• Longer follow-up periods were associated with smaller effect sizes, suggesting benefits may attenuate without sustained support.

The headline take: across modalities, how well prepared a patient is going into a session appears to matter more than how many post-session debriefs they get. This is consistent with clinical experience, where first-session anxiety, trust in the therapist, and intention-setting strongly shape what happens during the drug experience. The finding does not mean integration is useless — the trials included mostly brief post-dose protocols, and naturalistic integration happens over months.

What good preparation looks like

• Medical and medication history. Including serotonergic medications (SSRIs, SNRIs, tramadol, MAOIs), cardiovascular status, and family history of psychosis or mania.
• Trauma history assessment. Not to exclude patients, but to orient the therapist to what may surface and to plan ahead for containment.
• Intention-setting. Short, personal, realistic goals. "Understand my relationship with my father" beats "heal my depression."
• Practical orientation. What the substance will feel like, how long it will last, what to do if anxiety spikes.
• Informed consent. Known risks, including rare ones (HPPD, psychosis in vulnerable individuals, cardiac events for ibogaine or MDMA patients with cardiac disease).

What good integration looks like

• First contact within 24–72 hours. Even a brief check-in matters; the window when experience material is most accessible is short.
• Non-interpretive listening first. The patient narrates the experience; the therapist does not rush to assign meaning.
• Somatic tracking. Psychedelic experiences are often heavily body-based; integration that ignores the body misses material.
• Behavioral commitment. What specifically will you do differently this week? This month?
• Follow-up over weeks to months. Insights often crystallize gradually; relapse of depression symptoms is most likely in the weeks after the acute effect wears off.

The Bathje synthesized model

The integration model most widely used in practitioner training — adopted by MAPS in its Integration Station resources — was articulated by Bathje et al. and integrates four domains of post-session work:²

1. Cognitive: making sense of the content, reconciling experiences with prior beliefs, narrative building.
2. Emotional: processing emotional material that surfaced, often over weeks, sometimes including previously unprocessed grief, fear, or anger.
3. Somatic: noticing and working with body-based shifts — posture, tension patterns, breathing habits — that the experience may have changed.
4. Behavioral: translating insights into concrete changes, whether relational, vocational, or health-related.

Finding a qualified integration therapist

The market for psychedelic-adjacent services has grown much faster than the number of clinicians with real training. Three practical filters:

1. A clinical license in your state. Non-negotiable for anyone providing psychotherapy. Check directly with your state licensing board if you have doubts.
2. Psychedelic integration training from a recognized program. The programs below are the most established psychedelic therapy training programs for licensed clinicians. All require clinical licensure as an admission criterion and offer continuing-education credit:
   • Fluence — Certificate in Psychedelic Therapy & Integration (PTI) and Advanced Certificate in Psychedelic Harm Reduction and Integration (PHRI). Most recognized integration-focused curriculum.³
   • California Institute of Integral Studies (CIIS) — Certificate in Psychedelic-Assisted Therapies and Research.
   • Integrative Psychiatry Institute (IPI) — ketamine-assisted psychotherapy and broader PAT training.
   • Naropa University — contemplative and transpersonal orientation.
   • Beckley Academy — self-paced and cohort online options.
   • Numinus, Vital (Psychedelics Today), Polaris Insight Center — other recognized options.
3. MAPS-affiliated or PAT-trial therapist. Therapists who have completed MAPS training or been trial therapists have the deepest in-session experience; not all are accepting private-practice clients.

Finding an integration therapist near you. Beyond the training-program directories above, our find a psychedelic-integration therapist tool lists the main US directories (Fluence, CIIS, Polaris Insight Center, MAPS/Lykos, IPI, Naropa, and Psychology Today's integration filter) in one place, with guidance on what a state license plus psychedelic-specific training should look like before you book. We don't maintain a separate city-by-city directory beyond that tool, since a therapist's actual license and training matter far more than geography — many also offer telehealth in states where they're licensed.

Cost and insurance

Integration sessions are typically billed as standard psychotherapy (CPT codes 90834, 90837). If the treating clinician is in-network, sessions may be partially or fully covered. The drug session itself, where it is legal (ketamine, Spravato), is usually the part that triggers the greatest variance in insurance coverage. Integration is generally the more accessible component financially.

What to avoid

• Retreats that only offer group integration the following morning and no structured post-retreat support.
• Clinicians who have attended one weekend workshop and present themselves as "psychedelic-informed" without deeper training.
• Coaches who suggest discontinuing prescribed psychiatric medication without involving the prescribing clinician.

How this fits with the therapy you\u2019re considering

Every other guide in this catalog points back here. That is deliberate: the drug is the smaller part of the intervention in almost every case, and the part that is most standardized. The therapy relationship — who you do this work with, how well prepared you are walking in, and how you make sense of the experience afterward — is where the variance in outcomes actually lives.

If you’re unsure which therapy to consider in the first place, the Which psychedelic quiz maps your goals, medical constraints, and legal situation to the therapies with the strongest fit.
