About

This site is informational, not clinical. N,N-dimethyltryptamine (DMT) and 5-methoxy-DMT (5-MeO-DMT) are Schedule I controlled substances in the United States. There is no legal medical use outside of FDA-authorized clinical research. We are not a clinic, do not provide referrals to underground providers, and do not sell substances or paraphernalia. This site collates peer-reviewed pharmacology, current clinical-trial activity, and federal legal context for researchers, clinicians, students, and curious adults. dmt.clinic is operated by AdvancedCare USA Inc. as an educational site. It is not a clinic, does not provide treatment, and is not affiliated with any trial sponsor or healthcare provider. Crisis support: 988 (US).

Educational only — legal status notice

DMT and 5-MeO-DMT are Schedule I controlled substances under the U.S. Controlled Substances Act. Possession, manufacture, and distribution are federal felonies. The only lawful access in the United States is through FDA / DEA-authorized clinical research or limited religious exemptions (UDV, Santo Daime — see below). This site does not provide referrals to underground providers and does not endorse extralegal use.

Pharmacology basics

DMT (N,N-dimethyltryptamine) is an indolealkylamine with high affinity at serotonin 5-HT₂A receptors. It is the principal psychoactive constituent of ayahuasca, where it is rendered orally active by harmala alkaloids (MAO-A inhibitors) from Banisteriopsis caapi. Smoked, vaporized, or injected DMT bypasses MAO and produces a rapid, short experience (typically 5–20 minutes for smoked, 15–30 minutes for IM).

5-MeO-DMT (5-methoxy-N,N-dimethyltryptamine) is a related tryptamine with markedly different pharmacology: it has high affinity at 5-HT₁A as well as 5-HT₂A, and the subjective experience is described differently — typically less visual, more ego-dissolving. It is found in the secretion of Incilius alvarius (Sonoran Desert toad) and in several plant species, and is also synthesized.

Both compounds are metabolized rapidly. Plasma half-life of DMT is roughly 10–15 minutes; 5-MeO-DMT is similar. Neither substance is associated with classical physical dependence, but both can cause cardiovascular and psychological adverse events, especially in uncontrolled settings.

Subjective experience research

Modern human research on DMT begins with Rick Strassman's IV-DMT studies at the University of New Mexico in the 1990s. More recent work — notably Imperial College London's continuous-infusion DMT studies (Timmermann et al., 2019, 2023) — has used fMRI and EEG to characterize the neural correlates of the DMT state. Findings include reduced alpha-band power, increased signal diversity, and patterns interpreted as relaxed precision-weighting under the predictive-coding framework.

For 5-MeO-DMT, observational and open-label survey research (Davis et al., 2019; GH Research Phase 2 data) reports rapid reductions in depression and anxiety scores, though placebo-controlled data remain limited as of early 2026.

Common subjective phenomena across both compounds include perceived encounters with autonomous entities, sense of profound ontological significance, and ego dissolution. These features have been catalogued formally but are not endpoints of any FDA-approved indication.

U.S. legal status — federal and state

Federal: Schedule I under 21 U.S.C. §812. DMT is explicitly listed; 5-MeO-DMT was added in 2011 (21 C.F.R. §1308.11). Schedule I means "no currently accepted medical use" and a high potential for abuse. Research requires a DEA Schedule I researcher registration and FDA IND.

Religious exemptions: Two federal carve-outs exist for ayahuasca use under the Religious Freedom Restoration Act: Gonzales v. O Centro Espírita Beneficente União do Vegetal (2006, U.S. Supreme Court, UDV) and a related ruling for Santo Daime branches. These are narrow; they cover specific named churches, not the public.

States and cities: A handful of cities — including Oakland, Santa Cruz, Ann Arbor, Detroit, and Washington, D.C. — have decriminalized possession of entheogenic plants. Colorado (Proposition 122, 2022) decriminalized possession of DMT and related substances for adults statewide and authorized regulated supervised use. Decriminalization is not legalization and does not protect commerce or distribution.

Frequently asked

Is DMT the same as ayahuasca?

No. DMT is a single molecule. Ayahuasca is a brew traditionally made by combining a DMT-containing plant (often Psychotria viridis) with a Banisteriopsis caapi vine containing MAO inhibitors. The MAOIs allow orally ingested DMT to remain active. The duration (4–6 hours) and physiological profile of ayahuasca are very different from those of smoked DMT (10–15 minutes).

What's the difference between N,N-DMT and 5-MeO-DMT?

They are different molecules with different receptor profiles. N,N-DMT is what most people mean by "DMT." 5-MeO-DMT is generally described as less visual and more ego-dissolving. 5-MeO-DMT can be obtained from the Sonoran Desert toad (Incilius alvarius); both compounds are also synthesized for research.

Is DMT legal in the United States?

No, for the general public. Both N,N-DMT and 5-MeO-DMT are Schedule I controlled substances under federal law. Limited exceptions exist for FDA-authorized research and for specific named religious organizations under the Religious Freedom Restoration Act (UDV and Santo Daime branches).

Are religious ayahuasca churches legal to join?

The UDV and certain Santo Daime branches have specific federal injunctions protecting their ceremonial use. These do not extend automatically to other churches calling themselves "ayahuasca churches." Many such groups operating in the U.S. do so without legal protection. Consult an attorney before making assumptions about religious cover.

What harm-reduction information should I know if I'm going to use it anyway?

Harm reduction is not endorsement. Documented risks include severe hypertension (especially with 5-MeO-DMT), serotonin syndrome when combined with SSRIs/MAOIs/lithium, prolonged psychological distress, and HPPD (hallucinogen persisting perception disorder). 5-MeO-DMT specifically carries cardiovascular and respiratory risks that have been associated with deaths. We recommend reading the Multidisciplinary Association for Psychedelic Studies (MAPS) and DanceSafe materials and reviewing contraindications with a clinician who knows your history.

Can I participate in a clinical trial?

Clinical trials enroll based on specific eligibility criteria (diagnosis, age, prior treatments, geography). The trial finder above links each NCT ID to ClinicalTrials.gov, which lists current contact information and eligibility details for active studies.
