Plant Psychedelics
It's been used for thousands of years, studied seriously for decades, and is still mostly talked about in ways that don't help anyone. Here's what you actually need to know.
Dosing Guide
Dried vs fresh, species, strain, growing conditions, individual body chemistry, stomach contents, tolerance — psilocybin dosing has more variables than almost any other substance. The ranges below are for dried Psilocybe cubensis, the most common species. Other species vary significantly: P. azurescens can be 3–4x more potent by weight than cubensis; P. semilanceata (liberty caps) are typically 1.5–2x more potent. Use the lower end of any dose range when working with an unfamiliar species.
Freshness matters enormously. Poorly stored or old mushrooms can lose significant potency. "I did 3.5g and barely felt anything" is almost always a storage or strain issue, not a tolerance issue.
Microdose
0.05–0.3g
Sub-perceptual. Goal is no visible intoxication. Most people feel subtle shifts in mood, focus, or creativity. If you can tell you've taken something, your dose is too high for microdosing purposes.
Threshold
0.5–1g
First signs of effect — mild visual changes, mood lift, slight body feeling. Good entry point for first-timers who want to get a sense of the substance without committing to a full experience.
Moderate
1–2.5g
Clear psychedelic effects. Visual enhancement, emotional openness, altered sense of time. Most first experiences should be in this range. Still manageable if something unexpected comes up.
High
2.5–5g
Strong visuals, significant ego dissolution at the higher end, emotional intensity. The clinical trial standard dose is roughly 25mg psilocybin — equivalent to 3–4g dried mushrooms for most people.
Heroic
5g+
Complete ego dissolution. Boundary between self and experience disappears. Advanced territory only — approach with significant prior experience, intentional set and setting, and a trusted sitter.
⚠ The lemon tek variable
Soaking ground mushrooms in lemon juice pre-ingestion converts psilocybin to psilocin before it hits your digestive system. It accelerates and intensifies onset significantly — some people report it feels like 1.5-2x the dose. If you use lemon tek, reduce your dose accordingly and be prepared for a faster, more intense come-up.
Tim's Take
Your experience is your experience. It might be life-changing. It might be confusing. It might be nothing at all. All of those are valid outcomes. The biggest mistake I see people make is loading the experience with so much expectation that they spend the whole time grading it instead of living it. You don't have to unpack a profound insight. You don't have to have a breakthrough. Sometimes the most useful thing psilocybin does is remind you how to have fun and let go — and that's enough. Don't put so much pressure on it that you miss it.
Microdosing
Microdosing became a wellness trend before the science caught up. The result is a lot of people dosing too high, dosing too frequently, and expecting it to work like an antidepressant. The goal of a microdose is sub-perceptual. If you feel it, it's too much.
The Fadiman Protocol — the most studied approach:
Day 1
Dose day — 0.1–0.3g dried mushrooms. Take in the morning. Note effects throughout the day without judgment.
Day 2
Transition day — no dose. Effects from day 1 may still be subtly present. Good day for reflection and journaling.
Day 3
Rest day — no dose. Allows full clearance and prevents tolerance buildup.
Day 4+
Dose day again. Repeat the cycle for 4–8 weeks, then take a full month off to assess what's changed.
Microdosing is not a substitute for mental health treatment
The research is promising but not conclusive. If you're managing depression, anxiety, or PTSD, microdosing should complement — not replace — professional care. Personal or family history of psychosis or bipolar disorder: do not microdose without medical guidance.
Tim's Take
Most people microdose wrong — and it can cause real problems. The actual target is sub-perceptual: you should feel nothing. No visual shift, no mood lift you can point to, no sense that something is happening. The moment you can feel it, you've taken too much and you've left the microdose range entirely. Beyond the tolerance question, there's a real concern with long-term serotonergic load — sustained use can affect serotonin availability in ways that aren't benign. Microdosing isn't a daily supplement. It's a protocol that requires rest days, honest self-assessment, and a clear reason for doing it. If you're chasing the feeling, you're doing it wrong.
Set & Setting
Set is your mindset going in. Setting is your physical and social environment. Most difficult psychedelic experiences trace back to one or both of these being off — not to the substance itself. Trying to use mushrooms to escape something difficult is a setup for that difficult thing to become inescapable for six hours.
Set — what to actually check
How are you doing emotionally right now — not in general, right now. Are you in conflict with someone? Carrying unprocessed grief or fear? Are you using this to run from something or move toward something? Honest answers matter more than any dose calculation.
Setting — the physical environment
Safe, familiar, comfortable. No obligations for 8+ hours. Phone on do not disturb. People in your environment should be people you'd be comfortable crying in front of. Nature is generally excellent. Loud parties are generally not.
The sitter question
For doses above 2g, having a sober trusted person present is genuinely valuable. They don't need to do anything. They just need to be there and not be scared of what they're seeing.
When it gets difficult
Surrender is almost always the right move. Resistance amplifies difficulty. Moving toward uncomfortable material rather than away usually resolves it faster. Changing your environment — going outside, lying down, changing the music — can shift things significantly.
Tim's Take
Make it your own. Nature, your couch, a playlist, silence — trust yourself to know what you actually need. The guidelines exist because they work on average, not because they're law. What matters more than any specific setup is that you feel genuinely comfortable in it, and that you give yourself permission to adapt. Nothing is rigid. If you're outside and it starts feeling wrong, go inside. If the music isn't working, turn it off. Be fluid — bend, turn, change course. You don't have to know the path ahead. You just have to trust the direction you're moving in.
The Science
Psilocybin is a prodrug — your body converts it to psilocin, which acts primarily on 5-HT2A serotonin receptors. What happens downstream from that activation is where it gets interesting.
Default Mode Network
The DMN is your inner monologue, rumination, your sense of "I." Psilocybin suppresses DMN activity significantly — which correlates with ego dissolution and is thought to be the mechanism behind therapeutic effects on depression and rigid thought patterns.
Neuroplasticity
Psilocybin promotes dendritic spine growth and synaptic plasticity — making the brain more malleable and open to new patterns. This is the proposed mechanism behind long-lasting changes from a single session. The brain stays more plastic for weeks after.
BDNF & neurogenesis
Psilocybin increases Brain-Derived Neurotrophic Factor, a protein that supports neuron survival and growth. This may explain some antidepressant effects and why microdosing shows promise for certain conditions.
The research landscape
Johns Hopkins, NYU, and Imperial College London have all published significant clinical data. Psilocybin outperforms SSRIs in treatment-resistant depression in some studies. FDA Breakthrough Therapy designation granted 2018. Oregon and Colorado have legalized supervised therapeutic use.
Harm Reduction
Psilocybin mushrooms have an excellent physiological safety profile — non-toxic, non-addictive, lethal overdose is essentially impossible at any realistic dose. The risks are primarily psychological, and they're real.
SSRIs and SNRIs significantly blunt effects. If you're on serotonergic antidepressants, psilocybin may not work at typical doses. Do not stop your medication to try psilocybin without medical supervision. Serotonin syndrome risk with lithium is real and serious.
Personal or family history of psychosis or schizophrenia is a hard contraindication. Psilocybin can precipitate psychotic episodes in predisposed individuals. This isn't a risk to manage around — it's a reason not to use.
HPPD is real but rare. Hallucinogen Persisting Perception Disorder — persistent visual disturbances after use — can occur with psilocybin. Risk increases with frequency of use and high doses.
Identification matters if you're foraging. Psilocybe mushrooms have toxic lookalikes. Galerina marginata can be lethal and resembles some Psilocybe species. When in doubt, don't.
Tolerance builds fast and clears fast. Taking mushrooms two days in a row produces significantly diminished effects. Most people need a minimum of two weeks between experiences to maintain full sensitivity.
Nausea on come-up is common. Lemon tek, mushroom tea, or an empty stomach can help. It usually passes within 30–45 minutes as the experience begins.
Integration
A powerful psilocybin experience without intentional integration is like having a profound conversation and immediately going to sleep and never thinking about it again. The neuroplasticity window — the period of increased brain malleability after a session — is an opportunity. What you do in the days and weeks after matters as much as preparation.
Journaling
Write immediately after the experience, even if it's fragmented. Connections that feel obvious during the experience become hazy quickly. Capture images, emotions, and insights while they're fresh. Revisit in 48 hours and again in two weeks.
The day after
Rest. Clear your schedule if possible. The day after a significant experience often carries a gentle afterglow — use it. Avoid alcohol and stimulants for at least 24 hours.
Talk about it
Find someone you trust to process with — ideally someone with their own experience with psychedelics. Integration circles exist specifically for this. Psychedelic-informed therapists are valuable for more intense experiences.
What came up
Difficult material that surfaced deserves attention. The experience may have shown you something — a pattern, a relationship, a fear — your ordinary mind was avoiding. Integration means doing something with that information.
Tim's Take
Integration should be left to the person. Not every experience is a miracle or a turning point — and treating it like one when it wasn't sets you up for a weird kind of disappointment. If you need to process something, do it. Psychedelic-informed therapists are available online and worth seeking out if what came up was heavy. But maybe journaling is enough. Maybe a conversation with someone you trust is enough. Maybe you just need a few days and a good meal. Whatever happened in there, you're still you on the other side of it — and you were already enough before you started.
Legal Landscape
Psilocybin is Schedule I federally. The state-level landscape is moving faster than most people realize.
Decriminalized
Denver · Oakland · Santa Cruz · Ann Arbor · Washington D.C. · Seattle · Detroit · Several cities in MA and MI
Legal / Therapeutic
Oregon (Measure 109 — supervised therapeutic use) · Colorado (Prop 122 — healing centers) · More states pending
Federal Status
Schedule I · No accepted medical use federally · FDA Breakthrough Therapy designation creates a research pathway · This is changing
Decriminalization means personal possession is low enforcement priority — not legal. Legal therapeutic access means supervised sessions in licensed facilities, not personal use at home.
