Sacred Plants, Stalled Laws: Mexico and the Andes' Shared Path

Every autumn, groups of Wixárika pilgrims leave their communities and travel more than 400 kilometers east, on foot in the old way, toward the high desert of Wirikuta in Potosí. They carry candles, water from their home springs, and offerings wrapped in cloth. They are going to hunt hikuri, the peyote cactus, which in Wixárika cosmology is the heart of the deer god and the point where the physical world opens onto the sacred one. The mara'akame, the community's ritual specialist, leads the harvest according to rules that have nothing to do with Mexico City and everything to do with a relationship between people and plant that predates the Mexican state by centuries.

That journey happens legally, in a country where peyote is a controlled substance and simple possession can, on paper, land someone in federal custody. This is the paradox sitting at the center of plant medicine law in Mexico and across the Andean nations to the south: broad prohibition stays on the books while narrow, hard-won exceptions carve out room for Indigenous ceremony. Nobody legalized peyote, coca, or cannabis outright. Lawmakers and courts instead built small, specific doors into otherwise locked buildings.

Mexico's Supreme Court declared outright cannabis prohibition unconstitutional, and Congress still hasn't finished the job of writing a replacement law. Coca occupies a parallel limbo in Peru, Bolivia, and their neighbors, legal when chewed or offered to the apus in a mountain ceremony, illegal the moment it's treated as a commodity. These aren't separate stories about separate plants. They're two legal systems responding to the same unresolved question: how much room does a state make for Indigenous practice when the rest of the population is told the substance is dangerous.

Mexico's Narrow Legal Window for Peyote

The legal foundation for peyote use in Mexico sits in a single, narrowly worded provision: Article 195 bis of the Federal Penal Code, which shields the use of psilocybin mushrooms and peyote when practiced within the traditional ceremonial context of Indigenous peoples. It's a carve-out, not a legalization. The General Health Law's Article 245, Group I still lists mescaline, psilocybin, psilocin, and specifically named species like Psilocybe mexicana as controlled substances with no recognized medical use. Possession outside that ceremonial frame is, technically, a federal crime.

In practice, COFEPRIS and federal prosecutors have shown little interest in chasing down ceremonial use. Their enforcement energy goes toward trafficking networks and large-scale cultivation, not a mara'akame carrying a woven bag of cactus buttons back from Wirikuta. That's a choice about where to spend resources, not a formal legal guarantee, and it leaves practitioners dependent on the goodwill of whichever prosecutor happens to be paying attention that year.

Only a handful of Indigenous groups, principally the Wixárika (Huichol), hold recognized standing to harvest peyote at all, and even within those communities the mara'akames themselves regulate who picks, how much, and when, treating the plant as a living relative rather than a resource to be extracted. Wirikuta's status as a sacred site hasn't translated into consistent protection on the ground; mining concessions, agribusiness expansion, and highway construction have all encroached on the desert where hikuri grows, and enforcement of the cultural exemption varies depending on which federal or state office is involved. A September reform to Constitutional Article 2 reportedly strengthened the language around Indigenous cultural autonomy, according to legal analysis, giving advocates a stronger hook to argue that peyote access is a constitutional right tied to identity rather than a prosecutorial courtesy. Whether that reform changes anything on the ground in Potosí remains to be seen.

Cannabis in Legal Limbo Since the SCJN Ruling

Mexico's Supreme Court ruled, and again in a string of related amparo decisions in the years that followed, that blanket cannabis prohibition violates the constitutional right to free development of personality. Congress still hasn't passed the implementing legislation the court all but ordered it to write. The result is a country where growing, possessing, and consuming cannabis for personal use is protected by case law, but where no licensed dispensary exists anywhere in the country, no regulatory agency issues cultivation permits, and no legal supply chain connects a grower to a consumer. Anyone who wants product still buys it the way they always have.

The SCJN determination is worth reading closely because it went further than most press coverage suggests. The justices specifically named ideological use, personal use, cultural identity, ancestral custom, cosmogony, therapeutic application, and recreational use as categories deserving protection. That's an unusually broad list for a court ruling, and it explicitly put Indigenous ceremonial and ancestral use in the same sentence as recreational use, which is a different legal move than the narrower peyote exemption.

Early drafts of the implementing bill tried to carry that spirit into the regulatory text. One widely discussed version proposed reserving 40 percent of cultivation licenses for Indigenous peoples, ejidatarios working communal land, and other groups the bill classified as vulnerable, an attempt to make sure a legal cannabis industry didn't simply hand the market to whoever already had capital and lawyers. The version of the bill still circulating through Congress years later has scaled that commitment back considerably, trimming the set-asides and softening the language around who qualifies. Watching whether those numbers survive the final text tells you a lot about whose interests the law is actually built to serve.

Coca's Sacred Status Across the Andes

Coca's religious life in the Andes predates the Inca empire and never stopped. Across Peru, Bolivia, Chile, Ecuador, Colombia, and Argentina, the leaf functions as a medium of communication between people and the mountain spirits known as apus, and between people and Pachamama, the earth, and Inti, the sun. It's not a side element of ceremony. It is frequently the ceremony itself.

Ritual specialists called paqos conduct despacho offerings in which coca leaves, along with other items like llama fat, sweets, and small symbolic objects, are arranged and burned or buried as a gift to the apus in exchange for protection, good harvest, or health. A common gesture within these rituals has the paqo selecting three perfect coca leaves, known as a k'intu, and blowing on them before offering them to the wind, directing the breath toward a particular mountain or toward Pachamama herself. It's a small, precise motion, repeated across generations, that carries enormous weight in the ceremony's logic.

Alongside offering rituals sits a divinatory practice, coca leaf reading, sometimes called haywarikuy, in which a specialist scatters leaves and reads the patterns they form, their orientation, their texture, which side faces up, to answer questions about health, travel, or fortune. In Bolivia these readers are commonly called yatiri; in Peru, yachaq. Both titles describe a role that combines healer, counselor, and intermediary with the spirit world, occupying a position in Andean communities roughly analogous to the mara'akame's role among the Wixárika.

None of that cultural weight has moved coca off the international drug control schedules, where it remains listed as a controlled substance, with its sacred and traditional uses treated as a separate, unresolved category rather than grounds for removal.

Two Regions, One Legal Pattern

Line the three substances up and the pattern repeats with almost mechanical consistency. Mexico didn't legalize peyote; it exempted ceremonial use from a law that otherwise criminalizes mescaline. Bolivia didn't legalize coca nationally in the way cannabis-legal U.S. states have legalized cannabis; it carved out recognized traditional use through its coca leaf policies, while leaving the broader international scheduling untouched. Mexico's cannabis status sits somewhere in between, constitutionally protected but statutorily unfinished. In all three cases, legislators chose the narrowest possible fix rather than confronting prohibition head-on.

What actually protects a mara'akame carrying peyote through a highway checkpoint, or a paqo performing a despacho in a provincial plaza, isn't the statute itself so much as the enforcement discretion of whoever is on duty that day. Prosecutors and police officers decide, case by case, whether a given act of possession looks like ceremony or looks like trafficking, and that judgment call is where the real protection lives. Written law provides the vocabulary; practice provides the actual outcome.

Reform efforts in both regions have shown the same stalling pattern. Mexico's cannabis implementing bill has moved through multiple legislative sessions without reaching a floor vote that sticks. Various Andean proposals to decriminalize or more fully recognize coca beyond strictly traditional contexts have surfaced in Peruvian and Bolivian legislatures over the years and gone nowhere, even when courts or international bodies left the door open. Judicial victories keep outpacing legislative follow-through.

What connects peyote, cannabis, and coca most directly is the demand coming from Indigenous communities themselves: that cultural identity, not just religious practice narrowly defined, be recognized as a standalone basis for legal protection. That's a more expansive ask than a religious exemption, and it's the ask that keeps running into the slowest-moving part of each country's government.

None of these carve-outs appeared because a legislature woke up one day feeling generous toward plant medicine. The Wixárika fought for recognition of their relationship to hikuri through decades of organizing around Wirikuta's protection. Andean coca growers' unions and cultural organizations spent generations pushing back against eradication campaigns funded by foreign drug policy before Bolivia's traditional-use framework took the shape it has now. Mexico's cannabis amparo cases were filed by specific plaintiffs willing to spend years in court. Every narrow exception in this story has a name attached to the fight that produced it.

Until Mexico's Congress actually finalizes cannabis implementing legislation, the country will keep operating on the same arrangement it's already used for peyote for decades: tolerance in practice, near silence in statute. That's a workable arrangement for people with the right lawyer or the right community standing behind them, and a precarious one for everybody else, which is precisely the problem Indigenous advocates keep raising.

The detail worth watching isn't the next floor speech or press conference. It's whether the final cannabis bill restores anything resembling that original 40 percent license set-aside for Indigenous peoples and ejidatarios. A bill that quietly drops that number while keeping the ceremonial language intact will have told you, in the most concrete way possible, which part of the court's ruling the government actually intended to honor.
