I hold licenses on both sides of that line, so I want to lay out the distinction plainly.
Ketamine is medicine, and it runs through a prescriber
Ketamine care is health care. It requires a clinician, an evaluation, a diagnosis, and a prescription. Within that, there are two routes people conflate.
Spravato, the brand name for esketamine, is FDA-approved for treatment-resistant depression. It is administered in a certified setting with at least two hours of monitoring afterward, and because it is approved, insurance often covers it.
Sublingual and intravenous ketamine are prescribed off-label. Off-label prescribing is legal and routine across medicine, but it is a different regulatory footing: the approval that exists is for a different use, and coverage usually does not follow. That does not make it wrong. It makes it something you should know you are choosing.
Either way, someone with a prescribing license is responsible for your care, and there is a diagnosis in your chart.
Psilocybin services are not health care, by design
Oregon's psilocybin program is not a medical program, and the wording in the law is deliberate. Sessions take place at licensed service centers. The person who sits with you is a facilitator. You do not need a diagnosis, a referral, or a condition to qualify, because the program is not treating a condition.
That surprises people who arrive expecting a clinical pathway. It also protects them. A facilitator is not diagnosing you and not prescribing anything, and a facilitator who talks as though they are has stepped outside their license.
What actually decides it
A few practical things usually settle the question faster than any theory.
- Are you looking for treatment of a diagnosed condition, with a clinician accountable for the outcome? That is the ketamine conversation.
- Do you want insurance to carry part of the cost? Spravato is the only one of these with a real chance of coverage. Psilocybin services in Oregon are private pay, with no insurance mechanism at all.
- How much time do you have? A ketamine appointment fits in a morning. A psilocybin session is most of a day, plus preparation before and integration after.
- What are you currently taking? This is where the two paths stop being independent, and it deserves its own section.
The medication question, which is not optional
Oregon's required preparation session includes a screen with specific exclusions, among them lithium in the previous thirty days and a diagnosis of active psychosis, and some histories call for a different kind of support first. A careful facilitator asks what you take and why, and sometimes says not yet.
This is the part of the work where my clinical background is genuinely useful, and also the part where I have to be most careful about scope. When I am facilitating, I am not managing your medications. What I can do is recognize when something belongs in front of a prescriber, and say so, rather than proceeding because you were hoping I would.
Being on an antidepressant does not disqualify you from Oregon's program. That is worth stating plainly, because the opposite belief is common and it leads people somewhere genuinely dangerous. So do not stop a medication on your own in order to qualify for something you already qualify for. Any change belongs with your prescriber.
A reasonable way to choose
If you have never had a psychiatric evaluation and you are struggling, start there. It costs you little and it tells you a great deal.
If you have been through several medications and a course or two of therapy without lasting relief, treatment-resistant depression has an approved option worth asking about by name.
If what you are after is not symptom reduction but something closer to perspective, and you are stable enough to spend a long day inside your own experience, the psilocybin program exists for exactly that, and it does not require you to be ill to qualify.
And if you are unsure, say so out loud to whoever you are talking to. The answer to which of these fits is not supposed to come from a website. It comes from an intake, where someone asks about your history and is willing to tell you the answer is neither.
Please note: psilocybin facilitation is not medical or psychiatric care and is not a treatment for any condition. Nothing here is medical advice or a claim about outcomes. Oregon's program is for adults 21 and older, is private pay, and sits outside the health care system by design.
