If you’ve spent any time in the wellness corners of the internet lately, you’ve probably seen the word “microdosing” more times than you can count. Microdosing Psilocybin, LSD, or San Pedro (mescaline). Different plants (and one synthetic compound), different histories, different legal realities, and yet they all get lumped into the same conversation like they’re interchangeable. They’re not. And if you’re standing at the beginning of this path wondering which one is actually right for you, I hope this article can help bring you some clarity and answer your questions.
I’m not here to tell you which one to choose. You’ll need to rely on your own research and intuition for that. What I can do is give you a map of the terrain: why people are drawn to each one, how they tend to feel in the body, and who should think twice before starting, so you can make an informed decision instead of a guess. (A note on the legal side of things for each of the three is at the end of this post.)
A quick note before we go further: everything below is general education and anecdotal reporting, not medical advice, and it’s not a substitute for talking with your own doctor or therapist; and none of it replaces the professional care you may already be receiving.
Microdosing Psilocybin
Why people are drawn to microdosing psilocybin: Psilocybin is where most of the current clinical research is concentrated, so a lot of people come to it because there’s real, growing scientific language around it, not just anecdote. It’ also more easily accessible and more widely available than other medicines. Anecdotally, people report reaching for psilocybin for:
- Emotional support, release, and processing what they’ve been carrying
- Softening a harsh inner critic or persistent self-judgment
- Feeling more present in day-to-day life
- Loosening rigid, repetitive thought patterns or mental loops
- A sense of connection to something larger than themselves
How it tends to feel: Most people describe psilocybin at a microdose level as a subtle brightening, more mental flexibility, and an easier relationship with their own thoughts. It’s generally considered the most “cerebral” of the three, working primarily through the serotonin system.
Microdosing San Pedro (mescaline)
Why people are drawn to microdosing san pedro: People often come to San Pedro looking for something that feels less “in the head” and more embodied. It has a long history of ceremonial use, and many people are drawn to that lineage. Anecdotally, people report reaching for San Pedro for:
- Heart-opening and a felt sense of connection, to themselves, to others, or to nature
- Grounding, embodiment, and getting out of an overactive mind
- Emotional warmth or softness rather than sharp mental clarity
- A sense of ceremony, lineage, and ritual around their practice
- Processing grief or heavier emotional material at a gentler pace
How it tends to feel: San Pedro works on a longer timeline than psilocybin, with a slower onset and a longer window of effect. People often describe its energy as warmer, heart-opening, connecting, more physical, and more grounding. It also engages the adrenergic (fight-or-flight adjacent) system more than psilocybin does, which is part of why it can feel different in the body.
Microdosing LSD
Why people are drawn to microdosing LSD: Anecdotally, people who microdose LSD often describe reaching for it for reasons that lean more cognitive or productivity-focused than emotional. Commonly reported draws include:
- Creativity and generative thinking
- Cognitive focus, motivation, and sustained clarity across a workday
- A general mental “brightening” or lift in mood
How it tends to feel: People commonly describe LSD microdoses as more energizing and “sharper” than psilocybin, with effects that some report lasting longer into the day. Precision matters, as even small changes in dosing can bring subjectively different effects.
Following your intuition
Here’s something I want to name directly, because it matters more than most guides let on: your intuitive pull toward one of these medicines over the others is real information, not a distraction from the “real” decision-making process. If you keep finding yourself drawn to San Pedro even though your list of goals reads like a psilocybin brochure, that pull is worth listening to, not overriding.
That intuitive sense is also something to keep checking in with over time, not just at the start. It’s normal for what you need to shift: maybe you begin with microdosing psilocybin for emotional release, and months later find yourself pulled toward San Pedro’s slower, more embodied pace, or toward LSD for a season where focus matters more than depth. Feeling pulled toward a different medicine than the one you started with isn’t a sign you chose wrong the first time. It’s often a sign that your practice is doing what it’s supposed to do: revealing what you actually need next.
Let your intuition be part of where you start, and part of how you decide when it’s time to adjust or switch.
Who should think twice about any of these
This isn’t an exhaustive medical list, and it’s not a substitute for talking with your prescriber, but some general categories worth real caution around:
- Anyone currently on SSRIs, SNRIs, MAOIs, or lithium. Combining classic psychedelics with these medications carries real interaction risks, and this is a conversation to have with your prescriber, not something to navigate alone.
- A personal or close family history of psychosis, bipolar disorder, or schizophrenia. Psychedelics can be genuinely destabilizing for some people with this history. Consulting with a qualified professional is recommended.
- Pregnancy or breastfeeding. There isn’t safety data here, so this isn’t the time to experiment. There are anecdotal reports out there though if you want to look.
- Cardiovascular conditions, arrhythmia, or uncontrolled blood pressure, particularly relevant for San Pedro given its effect on the adrenergic system.
- Anyone in an unstable or acutely distressing period of life. Even at sub-perceptual doses, these substances can surface a lot, and that’s not something to do without support if things already feel shaky.
If any of this sounds like you, that’s not a door closing, it’s a sign to bring in a professional (a therapist, a doctor, a facilitator) before doing anything else. You can also begin with reviewing the psychedelic contraindications guide on the resources page of this website.
Answering the questions I get asked most
Which one is better for someone who’s never microdosed before? There’s no universal answer, but microdosing psilocybin tends to be an approachable starting point for a lot of people, largely because there’s more research, more community knowledge, and may be grown at home even. That said, “easiest to start with” isn’t the same as “right for you.”
What’s better for anxiety? Anecdotally, people managing anxiety more often gravitate toward psilocybin or San Pedro, both of which are commonly described as calming and grounding rather than activating. This is anecdotal reporting, not a clinical claim, and if you’re managing diagnosed anxiety, this is worth discussing with whoever you already see for that.
What’s better for depression? Psilocybin has the most research behind it specifically in the context of mood, though “research exists” is different from “this treats depression.” If you’re navigating a depressive episode, please don’t treat any of these medicines as a replacement for the mental health care you’re already receiving, or as a reason to pause it without talking to your provider first.
What’s better for ADHD? This is actually where LSD gets mentioned most often anecdotally, with people reporting more sustained focus and motivation compared to psilocybin. However, San Pedro/mescaline may offer some relief as well with its ability to work on serotonin, dopamine and adrenergic systems together. Again, this is self-reported experience, not a clinical recommendation, and it doesn’t replace an evaluation or treatment plan with your provider.
Do any of them have negative side effects? Yes, all three can. Commonly reported effects across all three include mild nausea, fatigue (especially early on), vivid or unusual dreams, and emotional material surfacing that you didn’t expect. Less commonly, people report anxiety spikes, headaches, or feeling “off” for the rest of the day if a dose runs slightly too high. None of these medicines are risk-free just because two of them are plant-based and decriminalized here.
So how do you actually choose?
Instead of asking “which one is best,” a more honest question is: what am I actually looking for? Are you looking for support with a racing mind and a nervous system that never fully lands? Are you looking for something more grounding, more physical, more connected to the body? Are you drawn to sustained focus more than emotional depth? None of these are wrong questions, and none of them have a universal answer. What’s true for your neighbor may not be true for you.
What I’d gently push back on is the idea that you need to figure this out entirely alone, by trial and error, with information scattered across forums and social media. A relationship with any of these medicines, done with real support (tracking, screening, someone to ask questions of when something feels off), tends to go very differently than one built in isolation.
Take what resonates, leave the rest
There is no universal right answer here, only the right answer for you, at this point in your life, with your body, your history, and your intentions. Wherever you’re starting from, start slowly, start informed, and don’t be afraid to ask for support along the way.
A note on legality
In Colorado, psilocybin and non-peyote mescaline (the compound in San Pedro) are decriminalized for personal adult use under the Natural Medicine Health Act. LSD is not included in that law. It’s synthetic rather than plant-derived, and it remains a Schedule I controlled substance, fully criminalized at both the state and federal level.
I’m a therapist, not an attorney, and this post isn’t legal advice. If you’re considering any path into this work, including a religious exemption route, please do your own research and talk with an attorney who focuses on psychedelic law before making decisions. This space is changing quickly, and the responsible thing is to get current, accurate information rather than relying on any single blog post, including this one.
