Drugs are not legal in Costa Rica in any recreational sense, but the country draws a sharp line between using a substance and selling, producing, or moving one. Personal consumption itself is not a crime. Nearly everything else involving controlled drugs is, and the main statute, Law 8204, punishes trafficking and distribution with eight to twenty years in prison.
Personal Use Is Not Criminalized
An inter-American review of Costa Rican drug policy confirmed that “drug use per se is not criminalized” under national law.1Organization of American States. Costa Rica – Multilateral Evaluation Mechanism Article 79 of Law 8204 handles public consumption as a health matter: officers who find someone using an unauthorized substance in a public space are directed to facilitate voluntary treatment at a public or private health center at no cost.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 Treatment is voluntary for adults; a minor caught using drugs is referred to the child welfare agency, PANI.
In practice, that means police can confiscate what you have on you and point you toward treatment, but they cannot charge you with a crime for consumption alone. Possession is a different story. The moment officers suspect the drugs are meant for anything beyond your own immediate use, the stop stops being a health intervention and becomes a criminal investigation.
How a Possession Stop Becomes a Trafficking Charge
Costa Rica does not set a weight threshold that separates lawful personal possession from trafficking. There is no gram limit, no “personal dose” definition in the statute. Police and prosecutors look at the full picture. The factors that push an encounter toward a trafficking charge:
- Quantity. Larger amounts suggest distribution even without a statutory cutoff.
- Packaging. Drugs split into individual baggies or doses rather than a single stash.
- Tools of sale. Scales, cutting agents, or similar equipment.
- Cash. Large sums, especially in small bills, that look like sales proceeds.
- Location and behavior. Being in an area known for drug sales, or signs of repeated transactions.
This case-by-case approach gives officers wide discretion. A relatively small amount can still produce trafficking charges if the surrounding evidence looks commercial. The absence of a clear quantity line is the single biggest source of legal risk for anyone carrying drugs in the country.
Prison Time for Trafficking
Article 58 of Law 8204 imposes eight to fifteen years in prison on anyone who, without legal authorization, distributes, manufactures, cultivates, transports, stores, or sells controlled substances. The same range applies to possession with intent to distribute and to trading in seeds or plants used to produce controlled substances.3United Nations Office on Drugs and Crime. Law No. 8204 – Articles 57-75
Dealing in precursor chemicals or production equipment carries the same eight-to-fifteen-year range under Article 73, rising to eight to twenty years when an organized criminal network is involved. Article 77 also pushes the range to eight to twenty years when aggravating circumstances apply, including offenses committed on an international scale.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 Anyone importing or exporting drugs across the border is almost certain to face that enhancement.
Medical Cannabis Is Legal, With Strict Limits
Costa Rica legalized medical cannabis and industrial hemp in March 2022 through Law 10113. The law authorizes cultivation, processing, and sale of cannabis for medicinal and therapeutic purposes, but only through a licensing system covering manufacturing, importing, and cultivating.
Access is narrower than the headline suggests. Only Costa Rican citizens and legal residents holding a prescription from a locally licensed doctor can obtain medical cannabis. Foreign prescriptions are not recognized. Bringing cannabis products into the country is illegal no matter what paperwork you carry from home, so THC vape cartridges, oils, and edibles can be confiscated at the border and can produce criminal charges. A visitor who relies on cannabis-based medication would need to consult a Costa Rican-licensed provider about a local prescription, and short-term availability for tourists is limited.
Recreational Cannabis Remains Prohibited
Recreational cannabis is still illegal. Costa Rica’s Constitutional Chamber struck down a bill that would have legalized recreational use, finding it incompatible with international drug treaties the country has ratified, including the 1961 Single Convention on Narcotic Drugs and the 1988 United Nations Convention Against Illicit Traffic in Narcotic Drugs. Those treaties sit above domestic legislation under Costa Rica’s constitution, which closes off recreational legalization unless the country withdraws from them.
If You Are Arrested as a Visitor
Foreign nationals face the same penalties as citizens. There is no lighter track for tourists. The U.S. State Department warns that possessing, using, or selling illegal drugs in Costa Rica can produce heavy fines and jail time, and that marijuana and marijuana-related products remain illegal.4U.S. Department of State.

If you are arrested, ask police or prison officials to notify your embassy. You have the right to a public defender and a translator for most court proceedings.4U.S. Department of State.

An Overview of the Criminal Law System in Costa Rica Because local prisons are crowded, courts sometimes substitute house arrest, which bars you from leaving the country and requires regular check-ins with judicial authorities.
The common mistake is reading Costa Rica’s relaxed reputation on personal use as general tolerance. Police in tourist areas know that assumption exists. The line between personal use and a trafficking charge is drawn by an officer’s judgment, not by a scale, and multiple baggies, extra cash, or the wrong corner can turn a short trip into years of foreign criminal proceedings.
