Are mushrooms legal in Costa Rica? It depends entirely on the mushroom. Culinary and other non-psychoactive mushrooms are freely grown, sold, and eaten across the country with no special permissions. Mushrooms that contain psilocybin are illegal to cultivate, possess for sale, transport, or distribute under Costa Rica’s main drug statute, even though personal use is handled as a health matter and enforcement against small-scale users has historically been light.
Culinary Mushrooms Are Unrestricted
Edible mushrooms without psychoactive compounds sit under ordinary food and commercial rules, not drug law. You can buy them in grocery stores and farmers’ markets, grow them, and cook with them without any license or registration. Costa Rica’s tropical climate supports a wide range of fungi, and commercially cultivated varieties are widely available.
Why Psilocybin Mushrooms Are Illegal
Costa Rica’s drug law is Law No. 8204, the Complete Revision of the Law on Narcotics, Psychotropic Substances, Drugs of Unauthorized Use and Related Activities. It defines controlled drugs by reference to the substances listed under three UN drug conventions, including the 1971 Convention on Psychotropic Substances.1United Nations Office on Drugs and Crime. Drug Laws/Individual Listing for Costa Rica Psilocybin appears in Schedule I of that 1971 convention, which puts it on Costa Rica’s controlled list automatically.
Article 58 of Law 8204 makes it a crime to distribute, manufacture, cultivate, produce, transport, store, sell, or possess-for-any-of-those-purposes a controlled substance, and it reaches natural products capable of producing controlled substances as well as synthetic drugs. Mushrooms containing psilocybin fall squarely within that language.2United Nations Office on Drugs and Crime.

Personal Use Versus the Law on Paper
Law 8204 draws a deliberate line between trafficking and personal consumption. Personal drug use is treated as a health matter, and Article 79 directs people who use drugs in public places toward voluntary treatment and rehabilitation rather than criminal prosecution.2United Nations Office on Drugs and Crime. Law No. 8204 – Complete Revision of the Law on Narcotics, Psychotropic Substances, Drugs of Unauthorized Use and Related Activities Using in public can still lead to confiscation and a referral to a treatment program.
Costa Rican authorities have historically concentrated enforcement resources on large-scale trafficking of cocaine and other drugs rather than on psilocybin, which is why psychedelic mushrooms are often described as being in a gray zone. The gap is real, but it is a matter of enforcement priorities rather than legality. The conduct is still unlawful, and priorities can shift.
Psilocybin Retreat Centers
Costa Rica hosts a growing number of psilocybin retreat centers, many run by foreign operators marketing ceremonial or therapeutic experiences. These businesses exist inside the same enforcement gap described above. Law 8204 contains no religious-use carve-out, no ceremonial exception, and no licensing pathway for psychedelic-assisted therapy.3United Nations Office on Drugs and Crime. Law No. 8204 – Complete Revision of the Law on Narcotics, Psychotropic Substances, Drugs of Unauthorized Use and Related Activities
Article 66 specifically targets this type of operation. Managers or employees of establishments open to the public who allow people to gather on the premises to consume controlled substances face one to six years in prison, and authorities can revoke the business’s license and order temporary or permanent closure.3United Nations Office on Drugs and Crime. Law No. 8204 – Complete Revision of the Law on Narcotics, Psychotropic Substances, Drugs of Unauthorized Use and Related Activities Retreats that have run for years without incident reflect prosecutorial choices, not legal protection.
Penalties If Enforcement Comes
Law 8204 does not treat psilocybin more leniently than other controlled substances. The main exposures for mushroom-related conduct are:
- Trafficking, cultivation, production, transport, storage, sale, or possession for any of these purposes under Article 58: eight to fifteen years in prison.2United Nations Office on Drugs and Crime. Law No. 8204 – Complete Revision of the Law on Narcotics, Psychotropic Substances, Drugs of Unauthorized Use and Related Activities
- Aggravated offenses under Article 77 (including supplying minors or pregnant women, distribution in schools or sports facilities, using minors, or acting as part of an organized group of three or more): eight to twenty years.2United Nations Office on Drugs and Crime.

- Facilitating consumption at a business open to the public under Article 66: one to six years, plus license revocation and closure.3United Nations Office on Drugs and Crime.

Taking Mushrooms Back to the United States
Dried culinary mushrooms are agricultural products. All agricultural items must be declared on CBP Declaration Form 6059B, and a CBP agriculture specialist at the port of entry decides whether the item meets US entry requirements. Failing to declare can lead to confiscation and civil penalties up to $1,000 for a first-time non-commercial violation.4U.S. Customs and Border Protection. Bringing Agricultural Products Into the United States
Psilocybin mushrooms are a different matter. Psilocybin is a Schedule I controlled substance under US federal law.5Drug Enforcement Administration. Drug Fact Sheet – Psilocybin Bringing them into the United States is federal drug importation, regardless of state or local decriminalization at your destination. Nothing about Costa Rica’s enforcement posture changes what happens on arrival at a US airport.
