Which psychedelic is right for me?
No web page can answer this for you, and anyone who answers it confidently is guessing. What is true: these medicines differ in length, intensity, legal access and how much research stands behind them. Those differences narrow the field a long way. The last step is a conversation with someone who knows your history.
This is the most common question people arrive with, and it is usually the wrong first question — not because it is naive, but because it puts the molecule before the person. Nobody can responsibly tell you which substance suits you without knowing your medical history, your medications, your mental-health history, where you live, and what kind of support you will have afterwards.
What a page like this can do is show you the real differences, so that by the time you talk to a practitioner you are asking sharper questions.
The six options, side by side
Read the legal column first. For most people in most U.S. states, legality removes more options than preference does.
| Medicine | Typical session length | Character | U.S. legal status (Oct 2026) | Research stage |
|---|---|---|---|---|
| Psilocybin | 4–6 hours, plus preparation and integration sessions | Perceptual and emotional; widely described as inward and hard to predict in advance | Schedule I federally. Supported legal access exists only through Oregon's licensed service centers, Colorado's licensed healing centers, or a clinical trial. Several cities have deprioritised possession enforcement, which is not the same as legal access. | Two Phase 3 trials in treatment-resistant depression met their primary endpoints (COMP005, COMP006). The sponsor has a rolling FDA submission underway and expects to complete it in Q4 2026; approval would also require DEA rescheduling. Not approved. (What the trials show) |
| MDMA | 6–8 hours alongside a therapy protocol | Emotionally open with little perceptual distortion; studied as an adjunct to talk therapy rather than on its own | Schedule I. Access only through a clinical trial or expanded access. | The FDA declined the PTSD application in August 2024. A resubmission without a new Phase 3 trial was reported in August 2026 but has not been publicly confirmed by the FDA. Not approved. (What the trials show) |
| Ketamine / esketamine | 40–60 minutes for an infusion; roughly two monitored hours for esketamine | Dissociative rather than classically psychedelic; usually given as a series of sessions | Schedule III and legally prescribable. Esketamine (Spravato) is FDA-approved for treatment-resistant depression and dispensed under a restricted-distribution (REMS) programme; generic ketamine is used off-label in clinics nationwide. | Approved for treatment-resistant depression as esketamine. Effects arrive quickly and generally require repeat dosing to hold. |
| LSD | 8–12 hours | The longest of the classic psychedelics, which makes the setting and the support around it matter more, not less | Schedule I. Clinical trials only. | Phase 2b results in generalized anxiety disorder were published in JAMA. The sponsor has announced positive topline results from two Phase 3 anxiety trials (August and September 2026); no application has been approved. Not approved. (What the trials show) |
| Ayahuasca / DMT | A ceremony typically runs 4–6 hours; vaporised DMT lasts minutes | Ceremonial and physically demanding — nausea and vomiting are an expected part of ayahuasca, not a complication | DMT is Schedule I. Narrow federal religious exemptions cover specific congregations only (the UDV, and some Santo Daime churches); they do not extend to the public. | Small pilot trials in treatment-resistant depression. Not approved. |
| Microdosing | Not a session — sub-perceptual amounts taken on a schedule | By design you are not meant to feel much; there is no journey to be guided through | Follows the parent substance, so psilocybin and LSD microdosing are federally illegal | Placebo-controlled trials have largely failed to separate microdosing from placebo. Treat strong claims here with more suspicion than usual. |
What actually narrows the choice
In practice, four constraints do most of the work — and none of them is "which one sounds most appealing."
1. What is legally available where you live
If you want supported, above-ground access in the United States today, the honest list is short: ketamine through a licensed medical provider, psilocybin through Oregon's or Colorado's regulated programmes, or a clinical trial. Everything else either requires travel or sits outside the law. That single fact eliminates most of the table for most people.
2. Your medications and medical history
This is the constraint people most often underestimate. Of the 281 people who completed our intake, 55 — one in five — told us they were currently taking medication. Antidepressants, mood stabilisers, cardiac medication and a personal or family history of bipolar disorder or psychosis all change the picture, and some of them change it to "not this, and not now." Twenty-six people who completed our intake named bipolar disorder; that is a conversation with a prescriber, not a question to settle by reading.
3. How long a session you can actually hold
An eight-to-twelve-hour LSD session and a forty-minute ketamine infusion are not variations on a theme. They demand different amounts of time, different childcare arrangements, different recovery days, and different amounts of trust in whoever is sitting with you.
4. Who supports you in the weeks afterwards
Integration is the part people skip and then regret skipping. Of 239 completed preference records, 71 people — about 30% — told us they were not yet sure what format they wanted at all. That uncertainty is worth taking to a consultation rather than resolving by guessing.
Why the fit is with the person, not the molecule
Two people can take the same substance in the same amount and have experiences with nothing in common. What reliably differs is who prepared them, who was in the room, and who helped them make sense of it afterwards. That is the part you can actually choose well — and it is the part the research keeps pointing at when it talks about "set and setting."
So the practical sequence is: find a practitioner you trust, bring your history and your constraints, and let the choice of medicine fall out of that conversation. Not the reverse.

Where our numbers come from
Figures attributed to Guides Collective on this page come from our own intake questionnaire, completed by 281 adults between 23 December 2025 and 1 August 2026. They describe the people who came to us, not the general population, and they are self-reported. We publish them because nobody else in this category publishes anything comparable — not because they settle a clinical question.
You don't have to decide alone
Tell us what you're working with and we'll show you the guides we'd choose for your situation. The medicine is a conversation you have with them — not a box you tick first.
