Question 1

Is psilocybin legal in the US?

Accepted Answer

Psilocybin is currently legal for therapeutic use in Oregon, Colorado, and New Mexico. It remains federally illegal but is decriminalized in several cities and states.

Question 2

Which states allow psychedelic retreats legally?

Accepted Answer

Oregon, Colorado, and New Mexico currently allow licensed psilocybin service centers. Ketamine therapy is legal in all 50 states.

Question 3

What is the difference between legal and decriminalized?

Accepted Answer

Legal means a state or jurisdiction has passed laws explicitly permitting supervised use, possession, or sale of a substance — like Oregon's licensed psilocybin service centers. Decriminalized means possession or personal use is no longer a criminal offense (typically resulting in a fine rather than arrest), but the substance is not officially legal to sell or distribute commercially. Decriminalization does not create a legal market for retreats.

Question 4

Is ketamine therapy legal in all US states?

Accepted Answer

Yes. Ketamine is the only psychedelic-assisted therapy that is legal in all 50 US states when administered by a licensed medical provider. It is FDA-approved as an anesthetic and the FDA has approved Spravato (esketamine nasal spray) specifically for treatment-resistant depression. Hundreds of ketamine clinics operate legally across the country, offering IV infusions, intramuscular injections, and oral lozenge protocols.

Question 5

Can I do an ayahuasca retreat legally in the US?

Accepted Answer

Ayahuasca contains DMT, a Schedule I substance, making it federally illegal in the US. However, two religious organizations — the União do Vegetal (UDV) and Santo Daime — have won Supreme Court cases granting them the right to use ayahuasca in religious ceremonies under the Religious Freedom Restoration Act (RFRA). Outside of these specific religious organizations, ayahuasca retreats are not legal in the US. Legal ayahuasca retreats are widely available in Peru, Costa Rica, Jamaica, and the Netherlands.
