Mexico classifies psilocybin and peyote as restricted substances, but constitutional protections for indigenous cultural and spiritual practices shield traditional Mazatec and Huichol use.
Mexico's Ley General de Salud (General Health Law) places psilocybin, psilocin, and mescaline in Group I of Article 245 — the category for substances with little or no accepted therapeutic value and high potential for abuse.
Article 245 is specific about the plants and fungi, not just the isolated compounds. Mescaline is listed alongside Lophophora williamsii (the peyote cactus) by name. Psilocybin is listed with hallucinogenic mushrooms of any variety, with Psilocybe mexicana, Stropharia cubensis, and Conocybe species named as examples.
Articles 247, 248, and 249 of the same law prohibit planting, cultivation, harvesting, processing, possession, trade, and consumption. On paper, Mexico's framework is among the most expansive prohibitions in Latin America.
Mexico's Constitution protects indigenous cultural and spiritual practices through Article 2, which recognizes indigenous and Afro-Mexican peoples as public law subjects with the right to self-determination and cultural autonomy.
The September 2024 constitutional reform to Article 2 strengthened these protections. Indigenous peoples gained the right to "decide their internal forms of coexistence and their social, economic, political, and cultural organization" — language broad enough to cover ceremonial use of plant medicines.
Article 4 of the Constitution adds a right to cultural identity and access to one's own cultural practices. Together, Articles 2 and 4 are the legal basis Mexico's indigenous communities and their advocates cite when arguing that the drug law prohibition cannot constitutionally apply to traditional spiritual use.
The Mazatec people of the Sierra Mazateca in Oaxaca have used psilocybin mushrooms in healing ceremonies for centuries before any drug law existed.
The mushrooms are called teinanácatl in Mazatec — literally "sacred children" or "holy mushrooms." The ceremony is called a velada, a night-long ritual led by a healer (curandera or curandero) involving prayer, chanting, and the ingestion of fresh or dried mushrooms. The mushroom most closely associated with Mazatec ceremony is Psilocybe caerulescens, though several species grow in the region.
María Sabina (1894–1985), a Mazatec healer from Huautla de Jiménez, is the most famous practitioner in the historical record. R. Gordon Wasson attended her velada in 1955 and published his account in Life magazine in 1957, introducing psilocybin mushrooms to the Western world. The resulting wave of outsiders destroyed her community's privacy. Federales raided Sabina's home repeatedly, and her house was burned down. She was never convicted of a drug offense — a fact advocates cite as early precedent for tolerance of indigenous ceremonial use.
Today, Huautla de Jiménez has become a destination for both cultural tourism and people seeking mushroom experiences. Established Mazatec healers generally do not offer services to outsiders in the way retreat centers do — the velada is a healing session tied to a specific person's need, not a scheduled group experience. See our psilocybin guide for how traditional Mazatec practice differs from modern therapeutic models.
The Wixáritari (Wixárika in singular; also called Huichol in Spanish) make an annual pilgrimage of roughly 800 kilometres from their homeland in the Sierra Occidental — spanning Nayarit, Jalisco, Durango, and Zacatecas — to Wirikuta, a high-desert sacred site in San Luis Potosí.
At Wirikuta, they harvest hikuri (peyote, Lophophora williamsii) as a sacred act of communion with their ancestors and the deer spirit, Kauyumari. Peyote is not a recreational substance within Wixáritari culture — it is the center of a cosmological system that the pilgrimage sustains.
The San Luis Potosí state government declared Wirikuta a Sacred Natural Area in 2001. The Wixárika Route was recognized by UNESCO as a tentative World Heritage site. Neither declaration changes the federal classification of peyote under the Ley General de Salud, but both signal that the Mexican state acknowledges the pilgrimage as a protected cultural practice.
The Wixáritari also face pressure from non-indigenous peyote tourists and, in some areas, organized groups harvesting peyote commercially for sale. Lophophora williamsii is a slow-growing cactus — it can take 10 to 15 years to reach harvestable size — making overharvesting a genuine conservation threat. See the peyote guide for more on peyote ecology and how the Wixáritari's situation compares to the Native American Church in the United States.
Mexico has no licensed psilocybin service center system for non-indigenous people — no equivalent of Oregon's licensed service centers or Jamaica's formally tolerated retreat industry.
What Mexico does have is a long-standing informal tolerance. Dozens of mushroom retreat operations run openly in Oaxaca, San José del Pacífico (a mountain village in Oaxaca known for wild mushroom use), and other areas. They market to international visitors, charge fees, and operate without COFEPRIS permits or drug-law exemptions.
Article 195 bis of the Federal Penal Code provides a partial legal basis: it limits prosecution for use of psychoactive substances in traditional spiritual practices or ceremonies. Some attorneys argue this provision covers non-indigenous-led ceremonies if they are conducted in a spiritual context. Others argue it was written specifically for indigenous practitioners and provides no shield for commercial retreats. No court has definitively resolved this question.
| Who you are | Activity | Legal risk level |
|---|---|---|
| Wixáritari member | Peyote pilgrimage / harvest at Wirikuta | Constitutionally protected; prosecution risk: essentially zero |
| Mazatec healer | Conducting traditional velada ceremony | Constitutional shield + administrative tolerance; prosecution risk: negligible |
| Indigenous community member (other) | Traditional ceremonial use | Protected in principle under Article 2; prosecution risk: very low |
| Non-indigenous retreat operator | Charging fees for mushroom ceremonies | Gray area; COFEPRIS targets trafficking, not ceremony; risk: low in practice, nonzero legally |
| Non-indigenous visitor / tourist | Attending a retreat or ceremony | Gray area; rarely if ever prosecuted; no statutory protection |
| Anyone | Trafficking / commercial supply | Fully prohibited; enforcement active |

Mexico's Supreme Court (SCJN) took up Amparo en Revisión 374/2020, a case that directly challenged Articles 245, 247, 248, and 249 of the Ley General de Salud as unconstitutional.
The petitioner argued that banning psilocybin mushrooms violated the constitutional right to free development of personality and the right to health. In the First Chamber's draft analysis, Minister González Alcántara Carrancá argued the absolute ban does not pass Mexico's strict proportionality test — the standard used to resolve conflicts between rights and public-health restrictions.
The First Chamber debated the case in 2024 but did not issue a final ruling before Mexico's 2025 judicial election, which replaced all Supreme Court justices. The new court, seated September 1, 2025, inherited the case. No decision had been issued as of June 2026. A ruling against the ban would set a precedent — likely requiring amparo proceedings by individual petitioners, not an immediate blanket legalization, but a signal that enforcement is constitutionally questionable.
Mexico, Brazil, and Peru each protect traditional psychedelic use through constitutional and cultural-heritage frameworks, but the strength and formality of each approach differs significantly.
| Feature | Mexico | Brazil | Peru |
|---|---|---|---|
| Substances covered | Psilocybin mushrooms; peyote (mescaline) | Ayahuasca (DMT + B. caapi) | Ayahuasca; San Pedro cactus (mescaline) |
| Legal basis | Constitutional Articles 2 & 4 (cultural rights) | CONAD Resolution 1/2010 (explicit authorization) | Cultural heritage decree (2008, ayahuasca) |
| Named statutory exemption? | No | Yes — resolution names the brew and authorized entities | Partial — heritage decree, not a drug-law carve-out |
| Non-indigenous coverage | No — retreats operate in gray area | Covers registered religious entities; commercial retreats in gray area | Broad — tourism and therapy retreats widely tolerated |
| Enforcement posture | Trafficking targeted; ceremonial use not prosecuted | Trafficking targeted; authorized religious use protected | Trafficking targeted; ceremonial use broadly tolerated |
| Formal licensing pathway? | No | Yes — for registered religious entities via CONAD | No formal system, but heritage status provides implicit cover |
Mexico's position is the least formally defined of the three: the widest drug-law prohibition on paper, the strongest constitutional cultural-rights framework, and the least formal implementation. Read about the Brazil approach in full on the Brazil ayahuasca authorization page, and compare with Jamaica's approach — the most permissive regime for non-indigenous visitors — on the Jamaica psilocybin page.

No, not for the general public. Psilocybin and psilocin are listed under Group I of Article 245 of Mexico's Ley General de Salud — the most restricted category. However, Mexico's Constitution protects indigenous cultural and spiritual practices, and federal authorities have not prosecuted Mazatec healers or Wixáritari peyote pilgrims who use these substances within their traditional ceremonies.
The Wixáritari (Huichol) hold a constitutional right to use peyote as part of their spiritual tradition under Article 2 of Mexico's Constitution. Their annual pilgrimage to Wirikuta to collect hikuri (peyote) has never been prosecuted. There is no explicit statutory exemption by name in the drug law — the protection is constitutional, not a written carve-out.
Mexico has no licensed retreat system for non-indigenous visitors. Therapeutic retreats and ceremonies outside indigenous communities operate in a legal gray area. COFEPRIS enforcement focuses on trafficking rather than personal or ceremonial use. Participating as a non-indigenous person does not carry the same constitutional protection indigenous practitioners hold, so the legal risk — while historically low — is not zero.
Mexico's Supreme Court (SCJN) debated Amparo en Revisión 374/2020 in 2024. The case challenged the psilocybin ban as an unconstitutional restriction on the right to free development of personality and the right to health. The First Chamber did not issue a final ruling. The new court seated in September 2025 inherited the case; no decision had been issued as of mid-2026.
María Sabina (1894–1985) was a Mazatec healer from Huautla de Jiménez, Oaxaca, whose velada ceremonies introduced psilocybin mushrooms to the Western world in the 1950s. She was never convicted of a drug offense despite repeated raids on her home after her ceremonies became internationally known. Her case is often cited as early evidence that Mexico historically tolerated indigenous ceremonial use, even before the constitutional framework for indigenous rights was fully developed.
Mexico, like Peru and Brazil, grounds indigenous psychedelic protection in constitutional cultural-rights frameworks. Brazil issued a formal authorization (CONAD 2010) that explicitly names ayahuasca and covers registered religious entities. Peru declared ayahuasca a national cultural heritage item in 2008. Mexico has neither a heritage declaration nor a formal authorization — its protection is constitutional in principle and relies on prosecutorial restraint in practice.
No. Harvesting and removing peyote from Wirikuta is illegal under federal law for non-indigenous visitors. A quirk in San Luis Potosí state law means personal consumption in the desert area is rarely prosecuted, but removal is not covered. The Wixáritari themselves have raised concerns about non-indigenous peyote tourism depleting their sacred sites — the peyote cactus takes 10 to 15 years to reach harvestable size.
