Law on Narcotics, Psychotropic Substances, and Unauthorized Drugs (Ley N.º 8204/7786)

The Law on Narcotic Drugs, Psychotropic Substances, Unauthorized Drugs, Related Activities, Money Laundering, and Financing of Terrorism (Ley sobre Estupefacientes, Sustancias Psicotrópicas, Drogas de Uso No Autorizado, Actividades Conexas, Legitimación de Capitales y Financiamiento al Terrorismo) regulates the prevention, trafficking, possession, and combat of drug trafficking in Costa Rica. Technically, the foundational law is Ley N.º 7786 (from 1998), and Ley N.º 8204 (from 2001) is the legislation that comprehensively amended it into the text in effect today—in practice, "Ley 8204" is the colloquial name used to refer to the current law.

The primary offense — trafficking (Articulo 58): carries a prison sentence of 8 to 15 years for anyone who, without legal authorization, distributes, trades, supplies, manufactures, transports, stores, sells, or cultivates the drugs regulated by this law (or the plants from which they are derived). The SAME penalty applies to anyone who POSSESSES those drugs for any of those purposes (selling, transporting, etc.) — in other words, this article penalizes possession when it is linked to one of those intended purposes, not possession in and of itself. Costa Rican courts have repeatedly acquitted individuals carrying relatively small amounts when none of those intended purposes were proven (personal consumption only) — Costa Rica does not have a law that expressly criminalizes consumption or simple possession for personal use.

Aggravating circumstances that increase the penalty to 8–20 years (Articulo 77): providing drugs to minors under 18, individuals with mental disabilities, or pregnant women; introducing or distributing drugs in educational, sports, or cultural centers, or prisons; using minors or drug-dependent individuals to commit the offense; if the offender is the parent or legal guardian of the victim; or if a group of 3 or more people is organized to commit the crime. If the person responsible works in an educational facility, they are disqualified from teaching for 6 to 12 years.

Reform with a gender perspective — "mules" in correctional facilities (Articulo 77 bis, added in 2013): when a woman smuggles drugs into a prison and lives in poverty, is a vulnerable head of household, is responsible for minors/elderly individuals/persons with disabilities, or is a vulnerable elderly adult, the sentence is reduced to 3–8 years (instead of up to 20). The judge may also order alternative measures to incarceration, such as house arrest or electronic monitoring, instead of prison time — recognizing the pattern of women living in extreme poverty being used as "mules" by drug trafficking networks.

Precursors and chemicals (Articulos 73-75): producing, transporting, or possessing chemical precursors or other substances used to process drugs without authorization carries penalties ranging from 1 to 15 years, depending on the specific conduct.

Note: this summary covers only the criminal drug legal framework (Titulo IV of a much broader law that also regulates, in other sections, money laundering and terrorist financing, which are not covered here). The exact quantity limit that a judge considers "personal consumption" is not set by a specific number in the law — it is evaluated on a case-by-case basis based on evidence of intent to traffic. For a real legal situation, seeking advice from a criminal defense lawyer or the Defensa Publica is essential.
