When NOT to Trip
Honest guidance on contraindications, mental states, medications, and life situations where the answer is 'not now' or 'not ever.'
When NOT to Trip
The most important decision you make about psychedelics may be the decision not to take them. This page is unambiguous about when psychedelics are dangerous, ill-advised, or simply poorly timed.
”Not Ever” — Strong Contraindications
These situations carry significant documented risk. The answer is not “be careful” — it’s “don’t.”
Personal or Family History of Psychotic Disorders
If you have a personal history of schizophrenia, schizoaffective disorder, or delusional disorder, classical psychedelics are contraindicated. The risk of triggering relapse or worsening prognosis is substantial.
If you have a first-degree relative (parent, sibling, child) with one of these conditions, your risk is elevated. Some experienced clinicians will work with you in highly controlled settings; unsupervised use is inadvisable.
Bipolar I Disorder
The risk of triggering mania is significant. Additionally, lithium — a common and effective treatment for bipolar I — creates a dangerous seizure risk when combined with psychedelics. The combination of bipolar I and lithium essentially rules out psychedelic use without extraordinary circumstances.
Taking Lithium
Regardless of diagnosis, if you are taking lithium, do not combine it with LSD or psilocybin. The seizure risk is documented and serious.
Taking MAOIs
Monoamine oxidase inhibitors (certain antidepressants and herbal preparations) combined with psychedelics — especially DMT/ayahuasca — can cause fatal serotonin syndrome or hypertensive crisis.
Under 25 with Developing Psychiatric Conditions
The brain continues developing into the mid-20s. If you have emerging or unclear psychiatric symptoms, adding psychedelics to the mix can obscure diagnosis and potentially worsen outcomes. If you’re struggling and under 25, prioritize psychiatric evaluation and stabilization.
”Not Now” — Temporary Contraindications
These situations may resolve with time, treatment, or changed circumstances.
Active Suicidal Ideation with Intent or Plan
If you are actively considering suicide and have a plan or intent, psychedelics are dangerous. They can intensify emotional states unpredictably, and the impaired judgment during a trip can be catastrophic.
What to do instead:
- Call or text 988 (US Suicide & Crisis Lifeline)
- Text HOME to 741741 (Crisis Text Line)
- Contact a mental health professional immediately
This does not mean people with depression can never explore psychedelics. It means active, acute suicidal crisis is not the time.
Acute Grief or Recent Trauma
In the immediate aftermath of a death, assault, accident, or other major trauma, your nervous system is already overwhelmed. A psychedelic experience will likely intensify rather than resolve this state.
General guideline: Wait at least several months after major loss or trauma before considering psychedelics. Focus on stabilizing support: therapy, sleep, nutrition, social connection.
Unstable Living Situation or Relationship
If you don’t have a safe, private space; if you’re in an abusive relationship; if you’re unstably housed — these are not optimal conditions for psychedelic experiences. Set and setting include your overall life context.
Active Substance Dependence (Other Than Nicotine/Caffeine)
Using psychedelics to escape addiction without a structured plan often backfires. The exception: psilocybin for smoking cessation has promising trial data, but those trials are medically supervised. Self-treating active addiction with psychedelics is not harm reduction.
Recent Psychiatric Medication Changes
If you’ve recently started, stopped, or changed doses of psychiatric medications — especially SSRIs, SNRIs, or mood stabilizers — your brain chemistry is in flux. Wait until you’re stable on a new regimen and have discussed interactions with your prescriber.
Significant Sleep Deprivation
Don’t trip exhausted. Sleep deprivation amplifies anxiety, paranoia, and cognitive fragmentation. Rest first.
”Probably Not, But Talk to a Professional”
Borderline Personality Disorder
Opinions vary among clinicians. Some report benefits; others report destabilization, especially around abandonment fears that may surface during a trip. If you have BPD, work with a psychedelic-informed therapist and consider lower doses with extensive preparation.
Dissociative Disorders
The interaction between dissociative conditions and psychedelics is not well understood. Proceed only with specialized professional guidance.
Complex PTSD
Some people with complex trauma find psychedelics healing; others find them retraumatizing. The difference often comes down to preparation, support during the experience, and integration resources. Don’t go it alone.
Situational Red Flags
Even without medical contraindications, certain life situations suggest waiting:
- You’re doing this primarily to please a partner. Your motivation matters.
- You’re trying to avoid a difficult decision. Psychedelics won’t make the decision for you.
- You don’t have a safe space or a trusted sitter. These are non-negotiable for macrodoses.
- You feel pressured by a timeline. “I need to heal before the wedding/job/school year.” Healing doesn’t follow your calendar.
- You haven’t done the basic homework. If you haven’t read about set and setting, interactions, and what to expect, you’re not ready.
When Medications Complicate Things
| Medication | Risk Level | Guidance |
|---|---|---|
| SSRIs/SNRIs | Moderate | Discuss with prescriber. May blunt effects; serotonin syndrome rare but possible. Do not stop suddenly. |
| MAOIs | High/Dangerous | Contraindicated. Do not combine. |
| Lithium | High/Dangerous | Contraindicated. Seizure risk. |
| Tramadol | Moderate-High | Serotonin syndrome risk. Avoid. |
| Stimulants (Rx or recreational) | Moderate | Cardiovascular strain, anxiety. Avoid combining. |
| Benzodiazepines | Low-Moderate | May dampen experience; physical dependence risk if used as trip-killers repeatedly. |
The Honest Bottom Line
Saying “not now” or “not ever” is not failure. It is not weakness. It is not missing out.
Harm reduction includes the radical act of knowing yourself honestly and choosing safety over experience when the balance tips that way. There are many paths to healing. Psychedelics are one tool among many, and they are the wrong tool for some people and some moments.
If this page has ruled you out, that doesn’t mean you’re broken or beyond help. It means you deserve approaches that fit your specific situation. Therapy, medication, community support, meditation, movement, and time are all genuine, evidence-based paths.
