✅ Trip Preparation Checklist

Psilocybin is not safe for everyone, and some personal and family medical histories represent serious contraindications that should be treated as firm boundaries rather than guidelines. The most significant risk factor is a personal or family history of schizophrenia, schizoaffective disorder, or any psychotic disorder. Psilocybin can trigger or accelerate psychotic episodes in individuals with this genetic predisposition, and this risk extends to first-degree relatives of people with these diagnoses — not only to those who have been diagnosed themselves. If you or a parent or sibling has a history of psychosis, the risk is not worth taking regardless of dose.

Bipolar I disorder (which includes manic episodes) is another strong contraindication. Psilocybin can destabilise mood cycling and has been associated with triggering manic episodes in people with bipolar I. Bipolar II with a well-managed history and no current instability may carry lower risk, but should always be discussed with a psychiatrist before any consideration of psilocybin. Active suicidal ideation — meaning current thoughts of self-harm with or without a plan — is an absolute contraindication. While clinical research has shown psilocybin reduces suicidal ideation in certain populations over time, an active suicidal crisis is not the right context for a psychedelic experience, which can intensify emotional states dramatically and unpredictably.

Medication interactions require careful attention. SSRIs (selective serotonin reuptake inhibitors) and SNRIs significantly blunt the subjective effects of psilocybin, often to the point where the experience is minimal. This is because psilocybin's primary mechanism involves agonism at the 5-HT2A serotonin receptor, and SSRIs cause receptor downregulation over time. Some people discontinue SSRIs before a session, but this must only be done under psychiatric supervision — abrupt discontinuation carries serious risks including discontinuation syndrome and mood instability. Lithium carries a particularly important warning: there are documented case reports of seizures occurring when lithium is combined with psilocybin. The mechanism is not fully understood, but the interaction appears to lower seizure threshold, and combining them should be considered genuinely dangerous. Anyone taking lithium should not use psilocybin.

Intention-setting is often reduced to asking "what do I want to get out of this experience?" — but this framing is incomplete and can lead to frustration when the experience does not deliver the insights or emotions you sought. A more honest and useful question is: "What am I willing to face?" Psilocybin is not reliably a pleasure machine or a healing vending machine. It amplifies what is already present in your psychology, and that includes material you may have been avoiding — grief, shame, fear, unresolved relationships, core beliefs about your worth and place in the world.

Effective intention-setting involves sitting with a written statement — not a wish list, but a genuine declaration of openness. The tradition of writing intentions in clinical psilocybin research asks participants to reflect on what they hope to understand, what they are afraid of, and whether they are genuinely willing to receive difficult or uncomfortable information. This matters practically: people who enter a session with rigid expectations ("I want to feel love and connection") often fight the experience when it goes somewhere else, which is where challenging trips come from. Those who enter with open curiosity ("I am willing to look at whatever comes") tend to navigate difficult material more effectively. Your intention does not control the experience — it shapes your relationship to it.

Fasting for 4–6 hours before ingesting psilocybin is widely recommended and for good reason. A full stomach significantly increases the likelihood of nausea during onset — a common and unpleasant side effect that can dominate the early phase of the experience. Psilocybin is metabolised to psilocin in the gut and liver, and gastric activity during this process often causes queasiness. Fasting does not eliminate nausea, but it reduces both its frequency and severity. A light snack of a few crackers or a small amount of fruit is acceptable if you are prone to low blood sugar, but a heavy or fatty meal in the hours before should be avoided. Many experienced practitioners recommend ginger tea around 30 minutes before the session, as ginger has well-established anti-nausea properties and does not interact negatively with psilocybin.

Hydration matters — dehydration makes the experience more physically uncomfortable and can worsen headaches in the post-session period, which are among the most commonly reported aftereffects. Drink adequate water in the 24 hours before, but avoid overhydrating immediately before the session. Alcohol should be avoided for at least 48 hours prior: it disrupts sleep architecture, elevates baseline anxiety, and its after-effects (even mild ones) reduce the quality of the psilocybin experience substantially. Sleep quality in the days before the session is equally important. Poor sleep amplifies anxiety and emotional reactivity — both of which will be magnified during the experience. If you have been sleeping badly due to stress, it is worth postponing the session until you have had two or three nights of adequate rest. Cannabis should also be avoided in the 24 hours prior, as the interaction with psilocybin is unpredictable and can intensify the session beyond your intended range.

"Set and setting" is the foundational harm-reduction principle for psychedelic use, articulated by Timothy Leary and subsequently validated through decades of clinical research. "Set" refers to mindset — your psychological state, intentions, and expectations. "Setting" refers to the physical and social environment in which the experience takes place. Both require deliberate preparation. For the physical environment: room temperature should be comfortable and controllable — psilocybin commonly causes temperature dysregulation, and the ability to add a blanket or open a window gives you options. Having access to outdoors or a garden is a significant asset; natural environments provide an enormously stabilising effect during challenging moments, and many people report their most meaningful experiences happening during time spent outside.

Remove clutter and sources of visual chaos from your space before the session. Under psilocybin, ordinary objects can become intensely visually engaging, and a cluttered environment full of electronic devices, notifications, and random objects can fragment attention and increase anxiety. Avoid mirrors or cover them: mirror-gazing under psilocybin can be deeply disorienting and, for some people, disturbing, as facial features and proportions distort in ways that can provoke anxiety or dissociation. Turn off or silence all devices except for a dedicated music player or playlist — having your phone available for calls and social media is a significant distraction that pulls you out of the experience and potentially exposes you to anxiety-inducing content at exactly the wrong moment. Designate a sober trip sitter if you are using more than a low dose — someone who knows where you are, can check in, and can provide calm presence if needed. The trip sitter does not need to intervene unless something is genuinely wrong; their primary role is simply to be present and to not panic.

Integration — the process of making meaning from and behavioural changes based on the experience — is where much of the lasting value of psilocybin comes from. Research consistently shows that the magnitude of any acute subjective experience does not predict long-term outcomes; what predicts outcomes is the quality of the integration work done in the days and weeks following. This planning should happen before the session, not after, because the post-session period is not ideal for making organisational decisions. Schedule the day after the session off from work or significant obligations before you ingest anything. The day after a meaningful psilocybin experience is often emotionally tender, reflective, and not well-suited to professional demands or complex social interactions.

Arrange a journaling session for the morning after — even if it is just 30 minutes of unstructured writing about what you remember, what you felt, and what questions arose. Many of the most useful insights from a session are accessible in this early window and fade significantly over the following days, much like dream content. If you work with a therapist, psychedelic integration coach, or participate in an integration circle, schedule a session within one to two weeks of the experience. This is the optimal window for working with the material while it is still emotionally alive. Let a trusted person in your life know that you are planning a session and may want to talk in the days following — not necessarily about the content, but simply having social support available matters. Isolation in the integration period is one of the most common contributors to difficult or confusing post-experience states.

The period from when the main effects resolve (typically 4–6 hours after ingestion) through the end of the evening is often called the "afterglow" — a state of emotional softness, reflective openness, and sensitivity that can be as valuable as the peak experience if treated well. The single most important thing to do in the immediate post-session hours is rest. Avoid screens — particularly social media, news, and anything emotionally stimulating or demanding. The nervous system is in a sensitive and permeable state, and negative content can imprint disproportionately. A short, gentle walk in nature if you feel stable enough is one of the most consistently well-regarded aftercare practices: the grounding effect of physical movement and natural environment helps the system settle.

Eat a light meal once you feel ready — something simple and nourishing, not heavy or complex. Soup, fruit, rice, or toast work well. Avoid alcohol in the evening following a session. The temptation to "come down" with alcohol is understandable, but it interferes with consolidation of the experience and can shift emotional states in unpredictable directions. Avoid cannabis for the same reasons — it can unexpectedly reactivate intense perceptual states in some people for several hours after psilocybin. Sleep is the most powerful integration tool available: the brain does significant consolidation work during REM sleep, and sleeping well the night of or night after a session strongly correlates with positive integration outcomes. If sleep is difficult, a warm bath, chamomile tea, or a guided body-scan meditation can help the nervous system settle enough to rest.
