State-by-state and country-by-country guide to DMT legality: Colorado decrim, DEA religious exemptions, and 4-AcO-DMT analogue law.
No. N,N-dimethyltryptamine (DMT) is a Schedule I controlled substance under the federal Controlled Substances Act (21 U.S.C. § 812). Schedule I classification means the federal government has determined the drug has no currently accepted medical use, a high potential for abuse, and lacks accepted safety for use under medical supervision. DMT has held this classification since 1970 when the CSA was enacted.
Possession of DMT is a federal felony. Distribution and manufacturing carry enhanced penalties. There is no federal therapeutic access pathway for DMT as of 2026 — no FDA Expanded Access program, no approved IND that creates a general compassionate use route, and no rescheduling proceedings underway. The April 2026 executive order on psychedelic therapies (Accelerating Medical Treatments for Serious Mental Illness) accelerates FDA and DEA review processes generally, but does not change DMT’s Schedule I status or create any legal access pathway.
The one meaningful exception at the state level is Colorado. Beyond that, the legal picture is defined by city-level deprioritization policies (which are not legal protections) and the narrow DEA religious exemptions described below.
| Jurisdiction | Status | Details |
|---|---|---|
| Federal (all states) | Schedule I | DMT has been Schedule I under the Controlled Substances Act since 1970. Federal law supersedes state law; even in Colorado, federal agents retain jurisdiction. |
| Colorado | Decriminalized (Prop 122) | The Natural Medicine Health Act (Proposition 122, passed November 2022) decriminalized personal possession of DMT for adults 21 and older under state law. No licensed DMT healing centers exist — the state’s therapeutic program currently covers psilocybin, with DMT healing centers expected to be addressed after June 2026. Sale and distribution remain criminal under state law. |
| All other states | Schedule I | DMT is a Schedule I controlled substance in all other US states. Several cities (Oakland, San Francisco, Santa Cruz, Berkeley, Arcata, Eureka in California; Detroit, Ann Arbor, Hazel Park in Michigan; and others) have passed deprioritization resolutions directing local police to treat entheogen enforcement as low priority — but these resolutions are not legal protections and do not bind state or federal law enforcement. |
Four US religious organizations have obtained confirmed DEA exemptions permitting their members to use DMT-containing ayahuasca in religious ceremonies. These exemptions were established through federal court litigation under the Religious Freedom Restoration Act (RFRA), following the Supreme Court’s landmark 2006 ruling in Gonzales v. O Centro Espírita Beneficente União do Vegetal (UDV), which found that the government had not demonstrated a compelling interest sufficient to override the UDV’s sincere religious practice.
The four confirmed exemption-holding organizations are:
These exemptions are organization-specific. They do not extend to other ayahuasca ceremony providers, neo-shamanic retreat centers, or individuals who independently claim religious use of ayahuasca. Organizations claiming RFRA protection without a court or DEA determination face prosecution risk.
4-AcO-DMT (4-acetoxy-N,N-dimethyltryptamine, also known as psilacetin or O-acetylpsilocin) is a synthetic tryptamine that is a prodrug of psilocin — meaning it metabolizes into psilocin in the body. It is not explicitly listed on the DEA’s Schedule I list of controlled substances.
However, the Federal Analogue Act (21 U.S.C. § 813) treats any substance “substantially similar” in chemical structure or pharmacological effect to a Schedule I controlled substance as a Schedule I substance — but only when intended for human consumption. The DEA and Department of Justice have argued that 4-AcO-DMT is an analogue of psilocin (which is itself Schedule I as a DMT-related tryptamine and psilocybin metabolite). Federal prosecutions under this theory have occurred; the “not for human consumption” label used by research-chemical vendors does not provide legal protection when there is evidence of intended human use.
Several US states also have their own analogue acts that may apply. 4-AcO-DMT should be treated as carrying meaningful federal and state legal risk regardless of its unscheduled status.
| Country | Status | Details |
|---|---|---|
| Brazil | Legal (ayahuasca) | CONAD (Brazil’s National Drug Policy Council) resolved in 2010 that ayahuasca is legal for religious use. Ayahuasca ceremonies are widely practiced, and numerous churches and retreat centers operate legally. Isolated or synthetic DMT is not separately authorized. |
| Peru | Legal (ayahuasca) | Ayahuasca was declared a national cultural heritage of Peru in 2008 (Supreme Decree No. 040-2008-PCM) and is widely available through licensed retreat centers in the Amazon region. It is used as a traditional medicine and in organized ceremony settings. Isolated or synthetic DMT is not separately addressed. |
| Portugal | Decriminalized | Since 2001, Portugal has decriminalized personal possession of all drugs, including DMT, as a public health measure. Possession of small quantities is an administrative offense referred to a dissuasion commission; trafficking and supply remain criminal. No therapeutic access pathway exists. |
| Netherlands | Decriminalized | Personal possession of small quantities of DMT is effectively decriminalized under Dutch drug policy, though DMT is a List I (hard drugs) controlled substance. Ayahuasca ceremonies operate in a legal grey area; several organizations have faced prosecution. Psilocybin truffles (not DMT) are the Netherlands’ better-known legal psychedelic. |
| Czech Republic | Decriminalized (misdemeanor) | Possession of small amounts of DMT (the Czech threshold for “small amount” is generally interpreted as a few doses) is a misdemeanor administrative offense rather than a criminal matter. Sale, production, and larger quantities are criminal offenses. No therapeutic access. |
| United States | Schedule I | DMT is Schedule I federally with no approved therapeutic use. Colorado has decriminalized personal possession under state law. Four religious organizations hold DEA ayahuasca exemptions. See full detail above. |
| United Kingdom | Class A | DMT is a Class A controlled substance under the Misuse of Drugs Act 1971 — the highest restriction category. Penalties for possession are up to 7 years; for supply, up to life imprisonment. No therapeutic or research exemption pathway exists for DMT outside of licensed research settings. |
| Australia | Prohibited | DMT is a Schedule 9 (Prohibited Substance) drug in Australia. Australia rescheduled MDMA and psilocybin for therapeutic use in 2023, but DMT was not included in that rescheduling and remains strictly prohibited with no therapeutic pathway. |
| Canada | Schedule I (CDSA) | DMT is a Schedule I substance under the Controlled Drugs and Substances Act. Unlike MDMA and psilocybin, DMT has not been the subject of significant Health Canada Special Access Program (SAP) approvals. No legal therapeutic access pathway exists. |
Legal DMT retreats — meaning retreats where DMT is administered in a legally protected context — are almost entirely ayahuasca retreats. The key jurisdictions are:
In the US, the only legal ayahuasca access is through membership in one of the four DEA-exempted religious organizations listed above. These are not retreat centers open to the public; they are religious congregations. Vaporized or synthetic N,N-DMT retreats have no legal pathway in the US as of 2026. The main DMT guide covers the clinical research pipeline (Small Pharma/Helus Pharma SPL026, Imperial College DMTx studies) in more detail.
Colorado is the only US state where personal possession of DMT has been decriminalized, under Proposition 122 (2022) for adults 21 and older. In every other state and under federal law, DMT (N,N-dimethyltryptamine) is a Schedule I controlled substance. Four religious organizations — UDV, Santo Daime, Iowaska Church of Healing, and the Church of Gaia — hold confirmed DEA exemptions to use DMT-containing ayahuasca in their ceremonies.
Personal possession of DMT is decriminalized in Colorado for adults 21+ under Prop 122 (the Natural Medicine Health Act, 2022). You may possess DMT for personal use without criminal penalty under state law. However, no licensed DMT healing centers exist in Colorado — the state's therapeutic program currently covers psilocybin only, with DMT-specific healing centers expected to be considered after June 2026. Federal law (Schedule I) still applies.
4-AcO-DMT (psilacetin) is not explicitly listed on the DEA's Schedule I list. However, it is a prodrug of psilocin, and the DEA and DOJ have argued it is subject to the Federal Analogue Act (FAA), which treats substances substantially similar to Schedule I drugs as Schedule I when intended for human consumption. Several arrests and prosecutions have occurred under this theory. Possession of 4-AcO-DMT carries meaningful federal legal risk even though it is not explicitly scheduled.
No country has legalized DMT for recreational or general therapeutic use. Portugal has decriminalized personal possession of all drugs since 2001, including DMT. The Czech Republic treats small-amount possession as a misdemeanor. The Netherlands has decriminalized personal possession of small quantities. In Brazil, ayahuasca (containing DMT) is legal for religious use and consumed in organized ceremony settings. In Peru, ayahuasca is legal as a traditional medicine and widely available through licensed retreat centers. Everywhere else, DMT is a controlled substance.
Legal DMT retreats — meaning retreats where DMT itself is served legally — are primarily ayahuasca retreats in Peru, Brazil, Costa Rica, and the Netherlands, where the legal status of ayahuasca varies by jurisdiction. In the US, the only legal ayahuasca access is through one of the four DEA-exempted religious organizations (UDV, Santo Daime, Iowaska, Church of Gaia), which are not retreat centers open to the public. Vaporized or synthetic DMT retreats have no legal pathway in the US as of 2026.
