A friend once told me she'd been microdosing psilocybin for six weeks and felt like the volume knob on her anxiety had been turned down by about a third. Not silenced. Just turned down. That's the kind of report you hear constantly in this corner of the psychedelic world — quiet, modest, hard to verify, and oddly compelling.

Microdosing psychedelics has moved from Silicon Valley curiosity to mainstream conversation over the past few years, and the questions I get from readers researching plant medicine almost always include some version of: should I try this before committing to a full ceremony? Fair question. Let's get into what microdosing actually is, what the science says, and what it doesn't.

What Microdosing Actually Means

A microdose is what researchers politely call a sub-perceptual dose — small enough that you don't feel high, don't see walls breathing, don't have any of the textbook psychedelic experiences. You can drive. You can answer emails. You can sit through a meeting without anyone suspecting a thing. That's kind of the whole point.

Roughly speaking, a microdose lands somewhere between a tenth and a twentieth of a recreational dose. For the most common substances people use, that works out to:

• LSD or 1P-LSD: around 5–15 micrograms
• Psilocybin mushrooms: 0.1–0.3 grams of dried mushroom
• DMT (smoked): 1.5–3 milligrams
• MDMA: 5–15 milligrams (though this one is contested and risky — more on that later)

Finding your dose is genuinely a trial-and-error process. People who are sensitive to serotonergic compounds can feel noticeable effects at amounts that another person wouldn't register at all. The rule of thumb most experienced microdosers follow: if you can feel it, you took too much. A proper microdose should slide under your perception, not announce itself.

How Often, and for How Long?

The protocol most people reference comes from researcher James Fadiman, who suggested dosing once every three to four days for around ten weeks, then taking a break. The logic is partly about tolerance — psychedelics build it fast — and partly about not letting the practice become invisible background noise. Others run shorter cycles, or use a two-days-on, one-day-off rhythm. There's no single right answer, and frankly, anyone who tells you there is hasn't been paying attention.

Why People Microdose in the First Place

The reasons cluster into two broad camps. The first is mental health — people dealing with depression, anxiety, PTSD, ADHD, or OCD who either haven't responded well to conventional medication or don't love the side effects that come with it. The second is what you might call optimization — focus, creativity, energy, mood, the feeling of being a little more present and a little less stuck in your own head.

The mental health angle is where things get interesting, and where I see the most readers genuinely curious. If you've been on SSRIs for a decade and you're tired of feeling emotionally flattened, the idea of a sub-perceptual dose of psilocybin twice a week sounds appealing. Journalist Erica Avery wrote publicly about microdosing LSD lifting her out of a depressive episode, and writer Ayelet Waldman built a whole book around her experience doing the same. Waldman's depression stayed gone after she stopped. Avery's came back — and she eventually concluded that occasional larger doses worked better for her than ongoing small ones.

Which is the most honest thing anyone can say about this practice: your mileage will vary. Dramatically.

What Does the Research Actually Say About Microdosing?

Here's where I have to put on my skeptic hat, because the gap between what people report anecdotally and what controlled studies have found is bigger than the microdosing community generally admits.

The Placebo Question

The obvious worry with any sub-perceptual practice is that the effects are mostly placebo. You believe the tiny dose will help, so it does. That's not nothing — placebo effects are real and clinically significant — but it matters for the question of whether the molecule itself is doing anything.

A double-blind, placebo-controlled trial published in Biological Psychiatry in 2019 tried to answer this. Researchers gave healthy volunteers LSD at 6.5, 13, and 26 micrograms versus a placebo. They found dose-related effects on subjective experience — feelings of vigor went up, but so did anxiety. Creativity scores actually got worse on LSD. Cognitive performance didn't improve. None of which lines up neatly with the rosy reports you read online.

One of the researchers noted that benefits might only show up after repeated dosing over time, which the study didn't measure. And the 26-microgram dose is arguably no longer a microdose at all — most harm-reduction guides classify it as a low recreational dose. So the picture is muddier than either side of the debate likes to admit.

The Self-Report Studies

Fadiman ran a much larger observational study with over a thousand participants across 59 countries. People microdosing LSD or psilocybin roughly every three days reported improvements in mood, productivity, focus, energy, relationships, and health habits. Some had even tapered off antidepressants in favor of microdosing.

Encouraging — but it's a self-report study with no control group. Fadiman himself was careful to note that people whose primary issue is anxiety probably shouldn't microdose, because some users find it amps anxiety up rather than down. That tracks with the controlled trial.

What About DMT?

A 2019 rodent study found that microdoses of DMT given over seven weeks improved measures of depression and anxiety without messing with cognition. Promising, but it's rats, not people, and the leap from rodent brain to human depression is famously treacherous. We don't have meaningful human data on microdosing DMT for mental health yet.

The Honest Caveats Nobody Mentions in Microdosing Forums

A few things I think are worth saying plainly:

1. Microdosing can increase anxiety in some people. If you already run hot, this is not a benign practice. Start lower than you think you need to, or skip it entirely.
2. The supply chain is unregulated. Unless you're growing mushrooms yourself or have a reliable analytical source for LSD, you don't actually know what you're taking or how much. Dose-by-eye with street acid is a recipe for an accidentally bigger experience than you bargained for at the office.
3. It interacts with medications. SSRIs, lithium, tramadol, MAOIs — these matter. Don't combine without doing serious homework, and ideally don't combine at all.
4. Microdosing MDMA is not like microdosing LSD. MDMA is neurotoxic at higher doses and the safety profile of long-term low-dose use is genuinely unknown. I'd skip this one.
5. It's not a replacement for the deeper work. The people I've interviewed who got the most out of psychedelics didn't get there through microdosing. They got there through full ceremonies — ayahuasca, psilocybin, ibogaine — with proper preparation, integration, and support around them.

Microdosing vs. the Full Ceremony Route

This is probably the question that matters most for readers weighing a retreat. Microdosing and ceremonial plant medicine are different tools doing different jobs. A microdose is a quiet nudge to your nervous system, maybe useful for taking the edge off a difficult month or unsticking a creative block. A full ayahuasca ceremony, or a psilocybin retreat with experienced facilitators, is something else entirely — a full confrontation with whatever you've been carrying.

People recovering from addiction, in particular, tend to find that microdosing alone doesn't get them where they need to go. The research on psychedelics and addiction recovery — the work on ibogaine for opioid dependence, psilocybin for alcohol use disorder, ayahuasca for trauma underlying substance use — involves full doses in carefully held settings, not sub-perceptual experiments at the kitchen table.

That said, some people use microdosing as a gentle on-ramp. A way to develop a relationship with these compounds and notice how their own system responds before committing to a multi-day retreat. There's logic to that, as long as you're honest about what microdosing can and can't do.

So Should You Try It?

If you're chronically anxious, on psychiatric medication, or already suspect you're someone who reacts strongly to substances, the honest answer is probably no — or at least not without serious thought and ideally a clinician who knows what you're up to. If you're a generally stable person curious about what a slightly quieter mind might feel like, and you have access to reliable material, it might be worth a careful experiment. Start lower than the standard protocol. Keep a journal. Take real breaks. Pay attention to what changes and what doesn't.

And if what you're really looking for is the deeper work — the kind that addresses trauma, addiction, or the persistent sense that something in your life is stuck — microdosing is unlikely to be the whole answer.
