Some physical and mental health conditions may increase the possibility of harm during or following a psychedelic experience.

Particular caution is warranted where there is significant current psychological instability or a personal or family history of psychosis, mania or bipolar-spectrum illness. Cardiovascular, neurological and other medical conditions may also be relevant, depending on the substance and circumstances.

Some of these questions require medical or psychiatric expertise rather than psychotherapy alone.

Prescribed medicines and other psychoactive substances can interact with psychedelic drugs in ways that alter their effects or introduce additional risk.

Prescribed medication should not be stopped, reduced or otherwise altered simply in order to take a psychedelic without appropriate advice from a doctor, pharmacist or other qualified prescriber.

Combining substances may also make effects less predictable and can introduce risks that would not be present with either substance alone.

An altered state may be more difficult to navigate when someone is already under severe stress, sleeping very little, emotionally destabilised or finding it difficult to remain grounded in ordinary life.

At such times, the understandable wish for relief can coexist with reduced capacity to manage whatever the experience makes more accessible.

Judgement, perception, orientation and coordination may all be affected during a significant altered state. Driving, traffic, heights, water, fire, machinery and other physical hazards can therefore become considerably more dangerous.

The environment does not determine what will happen, but it forms part of the conditions within which the experience unfolds.

Someone who becomes frightened, disorientated, physically unwell or unable to keep themselves safe may have difficulty obtaining help.

The presence of another person does not make psychedelic use safe and does not substitute for professional clinical care. At the same time, being completely alone can leave someone without practical help if something goes seriously wrong.

Anyone occupying a supportive role should be sufficiently sober and able to respond appropriately, including seeking emergency assistance where necessary.

Psychedelic and other altered states may involve increased emotional openness, dependency, uncertainty or suggestibility. This can make the behaviour, motivations and boundaries of anyone occupying a helping, guiding or authoritative role particularly important.

Questions about touch, sexual contact, privacy, recording, physical proximity and other significant boundaries are better considered while everyone involved has ordinary capacity to make decisions.

Consent given while sober should not be assumed to become broader or more permissive because someone is in an altered state.

A person's vulnerability should not be used as an opportunity to introduce sexual contact, impose interpretations, override previously established boundaries or encourage dependency.

Experiences of fear, grief, love, connection, bodily change, memory, imagery or spiritual significance can feel extraordinarily important and deserve to be taken seriously.

Their intensity, however, does not by itself tell us how much therapeutic change has occurred. Something may have become newly accessible while still needing considerable time and support to be understood, processed and incorporated into everyday life.

An overwhelming experience is not necessarily more therapeutic than a quieter one, and becoming aware of painful material does not mean that it has been resolved.

Altered states can give memories, images, beliefs and interpretations a powerful sense of truth or certainty.

Something can be psychologically important without necessarily being historically or literally accurate. It can therefore be useful to remain curious about what has emerged rather than making it immediately into the definitive explanation of one's history, relationships or difficulties.

The strength of an experience does not remove the need for reflection.

A psychedelic experience can sometimes create a compelling sense that something in life needs to change immediately. This may involve a relationship, work, family, treatment, identity, spirituality or another important area of life.

An insight can be taken seriously without being acted upon straight away. Allowing time for sleep, ordinary routine, reflection and conversation can make it easier to see whether something remains important once the intensity of the experience has passed.

Psychological distress during an altered state is not automatically a medical emergency. At the same time, a serious medical or psychiatric problem should not be dismissed as simply part of the experience.

Urgent help may be needed where someone:

• cannot keep themselves or another person safe;

• loses consciousness;

• has a seizure;

• develops serious breathing difficulty or other concerning physical symptoms;

• becomes dangerously agitated;

• is severely confused or disorientated;

• appears to be losing contact with ordinary reality in a way that compromises safety;

• develops severe suicidal or harmful impulses.

Where safety is significantly compromised, appropriate urgent or emergency medical services should be used rather than relying only on informal support.

The end of the acute drug effect does not necessarily mean that everything has returned to baseline.

Further assessment may be appropriate if there is persistent or worsening insomnia, anxiety, panic, marked changes in mood or energy, paranoia, unusual beliefs, perceptual disturbance, derealisation or depersonalisation, confusion, difficulty functioning in work or relationships, or difficulty distinguishing internal experience from events in the external world.

Seeking help after a difficult psychedelic experience does not require someone to conclude that the whole experience was a mistake. Sometimes the first task is simply to recover enough stability, sleep, orientation and perspective to begin understanding what happened.

Not every psychedelic experience is best understood through a trauma framework.

Some experiences are predominantly joyful, spiritual, embodied, creative, relational, existential or difficult to classify.

For people with trauma histories, however, earlier experiences of threat, neglect, attachment injury, loss or shame may become more accessible.

They may appear as memories or imagery, but also through fear, grief, bodily contraction, numbness, collapse, anger or a less clearly defined feeling that something important has been touched.

If someone remains overwhelmed, highly activated or dissociated afterwards, the immediate therapeutic task may be orientation, sleep, regulation and recovering a greater sense of safety and agency before exploring the material more deeply.

Pacing matters particularly when something has become accessible more quickly than the person can assimilate it.

What appears during an altered state may be clinically important without showing us, by itself, how much processing or change has taken place.

Integration is not solely a cognitive process.

Someone may have a coherent intellectual understanding of an experience while their body continues to respond as though something remains unresolved.

Following an altered-state experience, people may notice increased sensitivity, tension, exhaustion, activation, unusual bodily sensations, dissociation or changes in their sense of themselves or their surroundings.

Therapy may therefore pay attention to:

• bodily sensations and impulses;

• activation and settling;

• orientation to the present;

• mobilisation, tension, collapse or withdrawal;

• dissociation and disconnection;

• the capacity to remain present with emotion;

• relationships between bodily experience, meaning and relationship.

Depending on the person and our developing formulation, I may draw on relational psychotherapy, Sensorimotor Psychotherapy, Deep Brain Reorienting, parts-informed work and other approaches within my wider psychotherapy practice.

These are psychotherapy approaches, not psychedelic treatment protocols.

Altered-state experiences may influence how someone understands themselves and other people.

Love, closeness, grief, anger, loneliness, forgiveness, dependence, separation, fear or belonging can sometimes become especially prominent.

An experience may also leave someone with a strong sense that a relationship or another important aspect of life needs to change. That impression may deserve serious attention while still being allowed time to meet ordinary experience.

What feels compelling in the immediate aftermath may remain important, become more nuanced or acquire a different meaning once the person has returned to everyday relationships and routines.

Integration is not only for experiences that were frightening or difficult.

Some people seek psychotherapy following experiences of profound connection, compassion, unity, beauty, spiritual significance or a changed relationship with themselves.

Such experiences do not have to be reduced to symptoms, and therapy does not need to confirm one particular metaphysical or spiritual interpretation of what occurred.

The work can instead provide space for the person to consider the experience, the meaning they give it and what, if anything, they want to become part of their ordinary way of living.

Some psychedelic experiences are frightening, confusing or difficult to assimilate.

Afterwards, someone may experience:

• anxiety or panic;

• unusual bodily sensations;

• intrusive memories or images;

• emotional flooding;

• derealisation or depersonalisation;

• heightened sensitivity;

• sleep disturbance;

• shame or fear about what happened;

• existential uncertainty;

• changes in identity or self-experience;

• difficulty reconnecting with responsibilities or relationships.

Therapy does not require an immediate judgement that the experience was fundamentally good or bad.

A more useful starting point may be to ask what is happening now and what kind of support is needed. For some people, exploring meaning can begin relatively quickly. For others, restoring regulation, sleep, orientation and everyday functioning may need greater attention first.

Someone already in psychotherapy may have a psychedelic experience outside my involvement.

It may be self-directed, informally supported or facilitated elsewhere, or may occur within a research or other structured setting.

If this happens while we are working together, I encourage you to tell me.

Psychedelics can affect mood, sleep, regulation, dissociation, bodily experience, emotional accessibility, relationships and memory. These changes may also affect the course of psychotherapy.

Without knowing about the experience, changes might be attributed entirely to psychotherapy when several processes are contributing. The reverse can also happen: changes that were already developing through psychotherapy may subsequently be attributed entirely to the psychedelic experience.

Often the picture is mixed.

We do not always need to decide immediately what caused a particular change in order to work carefully with what has changed.

Looking at timing, functioning, relationships, bodily state and the evolving therapeutic process can often be more useful than reaching an early causal conclusion.

I regard a significant psychedelic or altered-state experience as clinically relevant information rather than something for which a client needs my permission or approval.

Knowing about it can help us understand changes in regulation, sleep, dissociation, mood, bodily experience or the pace and direction of the therapy.

If talking about the experience feels difficult, we can also explore that. You may anticipate judgement, worry that your autonomy will not be respected, feel ashamed or simply be uncertain whether the experience belongs in therapy.

The purpose of openness is to help us understand the therapeutic process more accurately.

I do not regard psychedelic integration as a single technique or protocol, and there is currently no single model of integration psychotherapy known to be appropriate for everyone.

I therefore approach this work as psychotherapy: relational, formulation-led, trauma-informed, attentive to bodily experience and responsive to the individual person.

My primary therapeutic orientation is relational psychotherapy. Depending on the person and what has emerged, my work may also draw upon or be informed by:

• Transactional Analysis and relational/psychodynamic thinking;

• developmental and attachment perspectives;

• Sensorimotor Psychotherapy;

• Deep Brain Reorienting;

• parts-informed approaches;

• EMDR-informed thinking;

• neuroscience and nervous-system regulation;

• neurotype, temperament, learning and sensory differences.

The person's development, history, relationships, body, temperament, neurotype, resources, health and present circumstances continue to matter.

A psychedelic experience can become an important part of the formulation without becoming the explanation for everything that follows.

Psychedelic experiences occur under very different conditions.

Self-directed use, informal support, facilitated experiences, ceremonial contexts, formal research and clinical treatment may differ substantially in screening, preparation, physical environment, interpersonal relationships, professional accountability and follow-up.

Psychotherapy can add an ongoing relationship in which an experience can be revisited and understood alongside the person's wider history and current life.

The therapeutic relationship may provide containment, perspective and somewhere to examine what remains meaningful, confusing, activating or unresolved. It also creates room to consider an insight without having to accept or act upon it immediately, and to notice how an experience may be influencing relationships, identity, behaviour and therapy itself.

Integration therefore involves more than explaining the experience. It concerns what becomes possible afterwards and what, over time, begins to find a place in the person's body, relationships, choices and ordinary life.

My role is not to tell someone what their experience means. It is to help them explore it thoughtfully while preserving agency, curiosity and appropriate uncertainty.

Promising findings from psychedelic research are sometimes discussed as though they apply automatically to psychedelic experiences occurring in very different circumstances.

Research studies typically operate within defined protocols that can include participant selection, medical and psychological screening, preparation, known substances, controlled conditions, trained personnel and structured follow-up.

Those conditions form part of the context in which findings about benefit and safety are produced.

An experience occurring independently, informally, ceremonially or with an unregulated facilitator may differ substantially from a research intervention.

This does not mean that every experience outside research or regulated healthcare will be harmful, nor that every experience within a formal setting will be beneficial.

Different contexts need to be understood on their own terms rather than treated as interchangeable.

Where someone is considering psychedelics because they are suffering or hoping for significant psychological change, that hope can be explored within therapy.

We can consider what they hope might become possible, what currently feels inaccessible and what they imagine an altered state might provide without turning psychotherapy into preparation for psychedelic use.

I do not begin from the assumption that psychedelic experiences are inherently healing or inherently harmful.

An experience may be meaningful, helpful, confusing, frightening, destabilising or difficult to interpret. More than one of these things can be true at the same time.

Research continues to develop, while substantial questions remain about who may benefit, who may be vulnerable to harm, how enduring psychological change occurs and how findings from carefully controlled settings translate into other contexts.

My position is one of openness combined with appropriate caution.

A powerful or unusual experience may deserve careful attention without being treated as proof of therapeutic depth or trauma resolution. Memories and interpretations may be psychologically significant without being taken as literal historical fact. Spiritual experiences can be explored without either pathologising them or requiring one particular explanation.

Sudden insight may also need time before it becomes a major life decision, and psychedelic experience does not replace the slower developmental, relational, embodied and behavioural processes through which change often becomes more established.

A significant altered-state experience can therefore be taken seriously without requiring it to become the explanation for everything that follows.
