Pharmacological Safety

MAO-B Interaction Matrix

MAO-B inhibitors (selegiline, rasagiline, safinamide) are prescribed for Parkinson's disease and sometimes depression. At therapeutic doses, they selectively inhibit MAO-B ... but selectivity is dose-dependent and can be lost. This matrix maps the interaction risk with each psychedelic compound.

Hard Stop
Caution ... MD Consult
Data Limited
CompoundInteractionRisk
DMT / AyahuascaHigh potentiation risk — MAO enzymes metabolize tryptamines; inhibition makes DMT unpredictably potentHard Stop
5-MeO-DMTHigh potentiation + serotonin toxicity risk — case reports of severe agitation, hyperthermia, rhabdomyolysisHard Stop
MDMAHypertensive crisis, serotonin syndrome — stimulant + MAOI combination potentially fatalHard Stop
PsilocybinPossible attenuation or potentiation; unpredictable — elevated serotonin from MAO blockade may alter responseCaution — MD Consult
LSDLikely attenuated; serotonin load risk at higher doses — historical data shows MAOIs may block LSD effectsCaution — MD Consult
MescalineInsufficient clinical data — theoretical serotonergic interaction riskCaution — Data Limited
MAO-B Inhibitor Wash-Out Guidance
selegiline
Half-life: ~10 hours
Recovery: 2–3 weeks (irreversible MAO inhibition)
Cessation must be supervised by neurologist — abrupt discontinuation in Parkinson's patients carries serious risk
rasagiline
Half-life: ~3 hours
Recovery: 2–3 weeks (irreversible)
Similar profile to selegiline. Do not discontinue without neurologist supervision
safinamide
Half-life: ~20–26 hours
Recovery: 1–2 weeks (reversible)
Newer agent with reversible MAO-B inhibition. Shorter recovery but still requires medical supervision
Critical Safety Reference

Medication Interaction Guide

If you take any of these medications, review the guidance carefully before considering any psychedelic experience. This is not exhaustive ... always consult your prescribing physician.

SSRIs / SNRIs
Hard Stop
Fluoxetine, sertraline, paroxetine, citalopram, venlafaxine, duloxetine
Risk: Attenuates psilocybin/LSD effects. LIFE-THREATENING serotonin syndrome with ayahuasca.
Guidance: Taper under MD supervision 2–6 weeks before. Ayahuasca: absolute contraindication without full washout.
MAOIs (non-selective)
Caution
Phenelzine (Nardil), tranylcypromine (Parnate), isocarboxazid (Marplan)
Risk: Dangerous potentiation of all serotonergic psychedelics. Hypertensive crisis.
Guidance: Hard stop for all psychedelics. 2–3 week washout minimum under psychiatrist supervision.
MAO-B Inhibitors
Caution
Selegiline (Eldepryl/Zelapar), rasagiline (Azilect), safinamide (Xadago)
Risk: High potentiation of DMT/5-MeO-DMT/MDMA. Unpredictable with psilocybin/LSD.
Guidance: See MAO-B Interaction Matrix. Neurologist must supervise any changes.
Lithium
Hard Stop
Lithium carbonate, lithium citrate
Risk: Seizure risk — ABSOLUTE contraindication with all classic psychedelics.
Guidance: Hard stop. No exceptions. Do not combine under any circumstances.
Stimulants
Caution
Amphetamine (Adderall), methylphenidate (Ritalin), lisdexamfetamine (Vyvanse)
Risk: Increased heart rate and blood pressure. Autonomic instability.
Guidance: Discontinue day of experience minimum. Discuss with prescriber.
Antipsychotics
Caution
Quetiapine, olanzapine, risperidone, aripiprazole, haloperidol
Risk: Block psychedelic effects via 5-HT2A antagonism. May indicate contraindicated conditions.
Guidance: Renders experience therapeutically ineffective. Underlying diagnosis may be absolute contraindication.
Tramadol
Hard Stop
Tramadol, tapentadol
Risk: Seizure risk + serotonin syndrome risk with all psychedelics.
Guidance: Hard stop. Do not combine.
Supplements to Flag
Caution
St. John's Wort, 5-HTP, Syrian rue (Peganum harmala), high-dose tryptophan
Risk: Serotonergic load increases serotonin syndrome risk.
Guidance: Discontinue 2 weeks before. Syrian rue contains natural MAO-A inhibitors (harmine, harmaline).

Tony Greenberg · The Diode of Perception

The diode of perception tethering movement to bone accelerates the other fundamental processes of life.

Beyond hunger, what you think of as necessity or craving is automatically fulfilled in the quickening of the senses — as spirit reaches in to taste the body.

Things of the past and future, things that you touch for pleasure — the pleasure is what electrical current you offer that thing.

If it is a living body — animal or human — it knows your love as you embrace its presence with your energetic breath: the waves of awareness stemming from that which you control your body from spirit.

The sharpening of will takes place as the simplicity of life — the places where your awareness cannot escape the body to forget itself in idle pastures, but remains alive in the sensation of time slowing across the curve of heartbeat weaving breath.

What the Numbers Are Saying

You are the instrument. Every medicine, every ceremony, every facilitator conversation begins with one question: what is the current condition of the thing being played? This assessment exists to answer that — not to gatekeep, but to give you an honest map before you walk into territory that rewards preparation and punishes shortcuts.
