Frequently asked questions about safety
What is psychedelic therapy?
Psychedelic therapy, also called psychedelic-assisted therapy, pairs a psychedelic or dissociative medicine with psychological support to treat conditions like depression, anxiety, and PTSD. Rather than a daily medication, psychedelic therapy uses a limited number of guided sessions built around preparation, the medicine experience, and integration afterward.
How does psychedelic therapy work in the brain?
Psychedelic therapy is thought to work by temporarily increasing neuroplasticity, the brain's ability to form new connections and adapt. Paired with psychological support, that window of flexibility may help people shift entrenched patterns of thought and behavior, though the exact mechanisms are still being studied.
Which psychedelics are used in therapy, and how do they differ?
The medicines most studied for psychedelic therapy are ketamine, psilocybin, and MDMA, which differ in how they work, their legal status, and how far along they are in research. Ketamine is the most widely available for legal clinical use in the United States today, while psilocybin and MDMA remain mostly limited to clinical trials or specific state programs.
Is psychedelic therapy legal, and what can I access right now?
Legal access to psychedelic therapy depends on the medicine. Psilocybin and MDMA therapy are not yet federally approved and are generally available only through clinical trials or state programs like those in Oregon and Colorado. Ketamine therapy is legal and available now, including through licensed telehealth providers, making it the most accessible form of psychedelic therapy for most people in the U.S.
Can I do psychedelic therapy at home?
Some psychedelic therapy can be done at home under clinical supervision. Ketamine therapy in particular is offered by licensed telehealth providers who prescribe treatment, guide preparation and integration, and monitor safety remotely. Other psychedelics generally require in-person, clinic-based settings where they are legal.
Which mental health conditions can psychedelic therapy help?
Psychedelic therapy has the strongest research base for depression, anxiety, and PTSD, with emerging study of conditions like prolonged grief and substance use. The evidence varies by medicine and condition, and psychedelic therapy is not appropriate for everyone.
Is psychedelic therapy safe, and who is a good candidate?
When delivered by qualified providers with proper screening, psychedelic therapy has established safety protocols. Whether someone is a good candidate for psychedelic therapy depends on their medical and psychiatric history, current medications, and the specific medicine, which a licensed provider evaluates before treatment.

Ketamine therapy is a clinician-guided treatment that uses a prescription dissociative medication to promote neuroplasticity and support lasting change for conditions like depression, anxiety, and PTSD.
There are more options for ketamine therapy today than ever before — from at-home programs like Mindbloom to in-clinic IV infusions, nasal spray treatments like Spravato, and other telehealth providers.
Ketamine therapy is one of the most extensively studied mental health treatments of the past two decades, with peer-reviewed research published across leading academic and clinical research institutions.
