Is ayahuasca legal in Costa Rica? The honest answer is that it sits in a grey area: DMT, the psychoactive compound in the brew, is a controlled substance under Costa Rican law, but the plant preparation itself has never been formally classified, and no one has been prosecuted for drinking it. What changed in January 2025 is that the Ministry of Health declared retreats offering ayahuasca for therapeutic purposes to be operating illegally.
Where the Grey Area Comes From
Costa Rica’s main drug statute, Law 8204, doesn’t maintain its own list of banned chemicals. Instead, it controls every substance listed in three international treaties the country has ratified, including the 1971 Convention on Psychotropic Substances.1United Nations Office on Drugs and Crime. Costa Rica Law No. 8204 – Complete Revision of the Law on Narcotics, Psychotropic Substances, Drugs of Unauthorized Use and Related Activities DMT appears on Schedule I of that Convention, the most restrictive tier.2United Nations Office on Drugs and Crime. Schedules of the Convention on Psychotropic Substances of 1971 So DMT is controlled in Costa Rica, even though it isn’t named in the body of Law 8204 itself.
Ayahuasca the brew is a different question. The International Narcotics Control Board, the body that monitors UN drug treaty compliance, stated in a 2001 letter that preparations made of plants containing DMT, including ayahuasca, are not under international control and are not subject to the 1971 Convention. Costa Rica has never formally adopted or rejected that interpretation through legislation or a court ruling. The question is simply unresolved.
What Law 8204 Actually Punishes
Even setting the ayahuasca-specific ambiguity aside, Costa Rica draws a sharp line between using a substance and selling one. Personal drug possession for immediate use is not a criminal offense. Law 8204’s penalties target distribution, manufacturing, transportation, storage, and sale.
Article 58 imposes eight to fifteen years of imprisonment on anyone who, without legal authority, distributes, manufactures, transports, stores, or sells controlled substances, or who possesses them for any of those purposes.3United Nations Office on Drugs and Crime (UNODC). Costa Rica Law 8204 – Articles 57-75 The same penalty applies to possession or trade in seeds or natural products used to produce controlled drugs. The qualifying phrase matters: possession alone isn’t enough for prosecution unless it’s tied to intent to traffic or distribute.
For a visitor drinking ayahuasca at a ceremony, that distinction matters. Personal consumption falls outside Law 8204’s criminal penalties. For the person preparing, serving, and charging for the brew, the exposure is far more serious, because those activities resemble the manufacturing and distribution Article 58 targets.
The January 2025 Ministry of Health Warning
In January 2025, Costa Rica’s Ministry of Health issued a public warning against the advertising, use, and consumption of ayahuasca and ibogaine for therapeutic purposes. The Ministry said any product based on ayahuasca must comply with national regulations for control and registration, and that neither substance has gone through the sanitary registration process required for medicines or therapeutic products in the country.
The Ministry’s position rests on three requirements no ayahuasca retreat currently meets:
- Sanitary registration confirming that a therapeutic product meets safety, quality, and efficacy standards. Ayahuasca has not been registered.
- Treatment conducted by certified professionals registered with the relevant professional association.
- Treatment delivered in facilities approved by the Ministry of Health, such as licensed hospitals or clinics.
The Ministry recommended that the public avoid retreats and ceremonies involving these substances and urged people to report the promotion of unregistered psychoactive substances to health authorities. Some retreats have reportedly faced closure or heightened scrutiny, though widespread, systematic enforcement has not yet materialized.
This is where retreat operators face the most practical legal risk. Whether or not ayahuasca itself counts as a controlled substance, the Ministry has clear authority over therapeutic claims. Any retreat marketing ayahuasca as healing, cleansing, or therapeutic is making health claims about an unregistered product, which is unambiguously illegal under Costa Rica’s health regulations regardless of DMT’s status.
Bringing Ayahuasca Across the Border
Whatever ambiguity exists around drinking ayahuasca inside Costa Rica disappears at the border. Costa Rica prohibits importing drugs, and customs authorities enforce that prohibition at airports and ports of entry.4International Trade Administration. Costa Rica – Import Requirements and Documentation Pharmaceuticals, drugs, cosmetics, and chemical products including precursor chemicals require import permits valid for five years and must be registered with the Ministry of Health. Natural medicinal products also require registration before sale.
Even if you view ayahuasca as an unregulated plant brew rather than a drug, trying to carry it through customs puts you at the intersection of drug prohibition and pharmaceutical import controls, while holding something that contains a Schedule I compound. The destination country usually poses equal or greater danger. The United States, for example, classifies DMT as a controlled substance without the plant-versus-chemical distinction. Article 58’s eight-to-fifteen-year sentence applies to transporting controlled substances without authorization, so attempting to leave Costa Rica with ayahuasca carries the same trafficking penalties as any other drug export.
What This Means If You’re Considering a Retreat
Drinking ayahuasca at a ceremony in Costa Rica is unlikely to produce criminal charges against you personally. Personal consumption is not criminalized, and there is no public record of prosecutions against individual ceremony participants. The legal risk sits with retreat operators, who face potential liability under both drug trafficking statutes and health regulations.
“Unlikely to be prosecuted” is not the same as “legal.” The Ministry’s 2025 warning signals that tolerance for the retreat industry may be shrinking. If authorities shut down a retreat you’re attending, you could be caught up in an enforcement action even without charges against you. And because no formal licensing system exists, there is no way to confirm a retreat is operating with government approval, because none of them are.
A useful test: if a retreat markets itself using therapeutic or healing language, it’s violating Costa Rican health regulations. If it frames the experience as spiritual or ceremonial without health claims, it occupies a genuinely grey space where enforcement has historically been minimal but is no longer guaranteed.
