Ketamine and Psychedelic Therapy on Long Island

How to Find Ketamine Care and a Psychedelic Therapist on Long Island

Finding ketamine treatment near you on Long Island comes down to two formats: a physical clinic you travel to, or an at-home telehealth program. In-clinic ketamine providers cluster on the Nassau North Shore around Great Neck and in western Suffolk near Melville and the Huntington corridor, thinning as you move east toward the East End. At-home care removes the geography question entirely: the ketamine prescription is handled online, and eligible adults complete sessions from home anywhere in New York. That matters because New York ranks 8th of 51 for access to care and first overall in the nation as of 2026, so the Long Island story is strong local infrastructure, not an access desert.¹

If you are searching for a psychedelic therapist or psychedelic-assisted therapy near you, it helps to know what is actually available. Ketamine is legal to prescribe in New York as a Schedule III medicine, while psilocybin and MDMA remain restricted, so the psychedelic-class therapist you can see today is, in practice, a licensed clinician guiding ketamine therapy.² That approach pairs each client with clinician oversight and structured program support rather than a prescription alone.

At-Home Ketamine Therapy Across Nassau and Suffolk Counties

Long Island is a two-county metro of about 2.9 million people, and access looks different across it. Nassau County, with roughly 1.4 million residents at about 4,900 people per square mile, is a dense inner-ring suburb where clinics are easier to reach.³ Suffolk County holds about 1.55 million people across nearly triple the land area at far lower density, stretching east toward the Hamptons and the East End where in-person options thin out.⁴ Mindbloom delivers at-home ketamine therapy to eligible adults across both counties, including Hempstead, Garden City, Great Neck, Long Beach, and Hicksville in Nassau, and Huntington, Babylon, Islip, Smithtown, Brentwood, and Riverhead in Suffolk, so the same clinician-guided program reaches the North Shore, the South Shore, and the East End alike.

Your Ketamine and Psychedelic Therapy Options on Long Island

Long Island offers real in-clinic care alongside at-home telehealth. Here is how the main options compare on where they happen, format, and typical cost.

In-clinic IV ketamine on Long Island is real and reachable, but cash-pay. An infusion clinic in Great Neck lists $550 per single infusion and $3,000 for a six-session course, with an introductory session at $450.⁵ A Suffolk clinic in Melville lists $525 per infusion.⁶ A practice serving both counties quotes a self-pay range of about $400 to $600 per infusion.⁷ These are out-of-pocket prices, and there is no in-network insurance coverage of IV ketamine for depression in New York. By comparison, Mindbloom's at-home ketamine therapy is $165 to $215 per session with a multi-session program, is HSA and FSA eligible, and may qualify for out-of-network reimbursement. If you are weighing formats, it is worth understanding how at-home sublingual ketamine compares with in-clinic IV infusions.

Spravato, the FDA-approved esketamine nasal spray, is offered at REMS-certified clinics on Long Island and may be covered by insurance for people who qualify, subject to the insurer’s prior authorization; otherwise it is paid out of pocket.⁶ Local coverage spans plans including New York Medicaid and Medicare alongside major commercial carriers, but approval is never automatic.

Many people searching for psychedelic therapy on Long Island are really asking about psilocybin, MDMA, LSD, or ayahuasca. None of these are legally available for therapy in New York today: psilocybin and MDMA are Schedule I, MDMA-assisted therapy is not FDA-approved, and there are no licensed psychedelic service centers in the state.² That is why ketamine is the psychedelic-class therapy you can legally begin now on Long Island, at home with Mindbloom.

What Ketamine Therapy Can Treat

Ketamine therapy is used most for depression, including treatment-resistant depression, and that is the flagship reason people on Long Island seek it out. It is often considered when first-line options such as talk therapy or antidepressants have not been enough. Mindbloom’s programs also address anxiety, PTSD, prolonged grief, burnout, and sleep difficulties. Depression and anxiety are the most common starting points, PTSD is a major focus given the strength of the outcomes evidence, and grief, burnout, and sleep round out what the treatment can support.

Mindbloom's Psychedelic Therapy Programs and Outcomes

Mindbloom has delivered more than 800,000 guided at-home sessions and is one of the largest at-home psychedelic-therapy providers. Its outcomes are peer-reviewed: a 2026 study of at-home subcutaneous ketamine reported results for depression, anxiety, and PTSD in a single study, and two earlier peer-reviewed studies cover its sublingual protocol, with research preprints extending the evidence to grief, burnout, and sleep. Mindbloom is the only at-home ketamine therapy provider with peer-reviewed PTSD outcomes.

The table below draws on Mindbloom’s own client data. Individual results vary.

_{⁸ Subcutaneous, six-session course (Parks 2026). Response = at least 50% reduction (PHQ-9/GAD-7) or at least 10 points (PCL-5); remission = final PHQ-9/GAD-7 under 5, or at least a 10-point reduction with PCL-5 under 33. ⁹ Grief (PGD-13), n=503; remission = no longer met diagnostic criteria (71.1% DSM-5-TR). ¹⁰ Burnout (MBI-GS), n=395; response = improved on at least one dimension (69.6%), remission = fell below the burnout threshold (59.5%). ¹¹ Sleep (PHQ-9 Item 3), n=13,963; single-item measure, remission = complete resolution; ketamine is off-label for sleep.}

Mindbloom offers tailored programs, built with mental-health thought leaders, that use the psychedelic modality to address specific outcomes rather than only prescribing medication for them. Programs include Grief, Habit Change, Anxiety, Depression, Self-Love, and Burnout.

• Mindbloom’s reported depression response rate is roughly 38% higher than the rate reported in a study of psychotherapy for depression (56.6% vs ~41%), and reached faster.⁸ ¹²
• Mindbloom’s reported PTSD response rate is about 32% higher than the rate reported in a study of first-line SSRIs (76.7% vs 58%).⁸ ¹³
• Mindbloom’s reported at-home PTSD response rate exceeds the rate reported in the leading repeated-infusion IV ketamine trial (76.7% vs 67%).⁸ ¹⁴
• Mindbloom’s reported depression response (56.6%) is at or above the rate reported in the largest controlled trials of single-dose psilocybin for depression (about 37–42%), on a far larger published evidence base and delivered at home rather than in a full-day, in-person licensed-center session.⁸ ¹⁵

Is Ketamine Therapy Legal on Long Island?

Yes. Ketamine is legal throughout New York and Long Island when prescribed by a licensed clinician. It is a federal Schedule III medicine, and using it for mental health is an established practice available now through telehealth.² Psilocybin and MDMA are a different matter: both remain Schedule I in New York, the state has no licensed psychedelic program, and neither Nassau nor Suffolk County has any local decriminalization or deprioritization policy on top of that statewide status. The national trajectory points the same way: an April 2026 federal executive order directed the FDA and DEA to accelerate research and access for psychedelic therapies, and ketamine is the one already available under medical supervision today.¹⁶

How At-Home Ketamine Therapy Works

At-home ketamine therapy starts with an online evaluation by a licensed clinician who reviews your history and decides whether treatment is appropriate. If it is a good fit, medicine is sent to your home and you complete sessions with preparation, a monitored dosing experience, and integration support afterward. A trained guide and clinician stay involved, and treatment frequency is personalized rather than set to a fixed schedule. Many people notice shifts early in a program, with benefits that build cumulatively over the full course. Ketamine has a long-established safety record in medical use, and a clinician screens for the conditions that would make it inappropriate before anyone begins.

Who Is a Good Fit, and What It Costs

Ketamine therapy is a prescription medical treatment, not a retail product, so it is available to eligible adults after a licensed clinician confirms it is a good fit. Mindbloom’s programs run $165 to $215 per session, are HSA and FSA eligible, and may qualify for out-of-network reimbursement, and the team can coordinate with an existing therapist or prescriber. Eligibility begins with an online clinical evaluation, and a licensed clinician confirms the plan before treatment starts.
