Country Access Report

Medical Access and Reimbursement in Mexico

Mexico remains restrictive for classical psychedelics, with psilocybin, LSD, MDMA, DMT and mescaline or peyote treated as Group I psychotropics and limited to authorised scientific research. Esketamine has public-system formulary recognition in the national Compendio, but real access depends on institutional adoption and procurement. Ketamine has controlled medical use, while depression treatment is off-label. Private ibogaine and 5-MeO-DMT services should be treated as unapproved private activity, not as national medical access.

Access by Compound

Compound-specific notes summarise what is realistically available through approved medical use, clinical research, exceptional access, or private care where the country report has verifiable information.

Compound Access

Psilocybin

Group I; authorised research only

Psilocybin, psilocin, and hallucinogenic mushrooms are Group I psychotropics under Mexico's General Health Law. Article 249 limits the acquisition of Group I substances to health-authority-authorised scientific research, so this is not a routine medical pathway. #

Compound Access

MDMA

Group I; authorised research only

MDMA is treated as a high-control psychotropic in Article 245. No Mexican market authorisation or routine reimbursement route was identified outside authorised research. # #

Compound Access

Esketamine

Formulary recognised; access is institution-dependent

Esketamine has EU and international trial evidence and is visible in Mexico's Compendio Nacional de Insumos para la Salud. That improves public-system legitimacy, but access still depends on local adoption, procurement, specialist administration and budgets. # # #

Compound Access

Ketamine

Controlled medical use; psychiatric use is off-label

Ketamine is a Group III psychotropic with recognised therapeutic use. It can exist in ordinary controlled medical care, but depression treatment remains off-label, with public evidence strongest for a small Mexico City-linked clinical study. # # #

Compound Access

DMT

Group I; authorised research only

DMT is listed as a Group I psychotropic. Reviewed sources did not show an authorised treatment or reimbursement route outside health-authority-approved research. #

Compound Access

5-MeO-DMT

Unapproved; private observational activity only

No approved Mexican medical pathway for 5-MeO-DMT was identified. Mexico-linked evidence comes mainly from private or naturalistic ibogaine plus 5-MeO-DMT observational work, not from national authorisation. #

Compound Access

Ibogaine

Unapproved private clinics; no national pathway

Ibogaine is not an approved medicine in Mexico. Private clinics operate and have contributed observational evidence, especially in cross-border treatment settings, but this is not a recognised national treatment or reimbursement pathway. # #

Compound Access

Ayahuasca

No authorised medical access verified

Mexico controls DMT and reviewed sources did not identify a national medical or reimbursement route for ayahuasca. Ceremonial or cultural contexts should not be treated as general medical authorisation. #

Compound Access

Mescaline

Group I; peyote context is culturally governed

Mescaline and peyote are listed in Group I. Wixarika sacred-route protection and the UNESCO inscription matter for Indigenous governance and peyote context, but they do not create a general medical access route. # # #

Compound Access

2C-X

No authorised medical access verified

Reviewed Mexican sources did not identify an authorised treatment or reimbursement route for 2C-family substances. Any public claim should be checked against current controlled-substance language before publication. #
