Drug laws in Puerto Rico operate on two tracks at once: the island’s own Controlled Substances Act (Title 24, Chapter 111) and the federal Controlled Substances Act, both of which apply in full because Puerto Rico is a U.S. territory. Simple possession without a valid prescription is a felony under local law, carrying a fixed three-year prison term with a range of two to five years. Recreational cannabis is illegal, though a regulated medical cannabis program has run since 2017. Larger cases involving trafficking quantities are often prosecuted in federal court, where mandatory minimums make the penalties considerably harsher.
Two Legal Systems, One Island
The federal Controlled Substances Act sorts drugs into five schedules. Schedule I covers substances the federal government treats as having high abuse potential and no accepted medical use, and it includes cannabis, heroin, LSD, and ecstasy. These prohibitions apply in Puerto Rico the same way they apply in any state.
Puerto Rico’s local law generally tracks the federal scheduling system, and the island’s Secretary of Health has authority over how new federal classifications are adopted locally.1Justia. Puerto Rico Code 24 2201 – Authority and Criteria of the Secretary of Health The practical result is that a drug offense on the island can be prosecuted under Commonwealth statute, under federal statute, or in some circumstances both. The choice of forum drives the sentence.
The clearest tension between the two systems is cannabis. Puerto Rico’s medical program, created by Act 42-2017, authorizes registered patients to purchase and use cannabis products. Federally, that same conduct is still a crime. Federal prosecutors have generally left compliant medical programs alone, but they keep the authority to act. Local compliance does not equal federal immunity.
Possession Penalties Under Local Law
Simple possession of a controlled substance without a valid prescription is a felony. A first conviction carries a fixed three-year prison term, with a range of two to five years depending on aggravating or extenuating circumstances, and a possible fine of up to $5,000.2Justia. Puerto Rico Code 24 2404 – Penalty for Simple Possession
A second or subsequent conviction jumps to a fixed six-year term with a range of four to ten years.2Justia. Puerto Rico Code 24 2404 – Penalty for Simple Possession
The statute builds in some flexibility for low-level offenders. If the court finds, on a case evaluation, that the person is not a danger to society and is not addicted to controlled substances, the judge may (with the prosecutor’s consent) substitute a fine between $1,000 and $10,000 plus up to six months of community service in place of prison.2Justia. Puerto Rico Code 24 2404 – Penalty for Simple Possession A 2015 executive order also directed judges not to imprison defendants caught with fewer than six grams of cannabis. That guidance does not change the underlying felony classification of the offense.
Drug Paraphernalia
Possession of paraphernalia is a separate felony. A conviction carries a fine of up to $3,000 or a fixed three-year prison term (ranging from two to five years). With aggravating circumstances, the fine can reach $5,000 and the term can reach five years.3Justia. Puerto Rico Code 24 2411b – Drug Paraphernalia A pipe, a scale, or similar items found alongside a drug can add a second felony count to the same arrest.
Distribution and Trafficking Under Local Law
Distribution penalties turn on the schedule and character of the substance. The heaviest sentences apply to Schedule I or II narcotics such as cocaine and heroin.
- Distribution of Schedule I or II narcotics (cocaine, heroin) is a felony carrying a fixed twenty-year prison term, with a range of ten to thirty years, plus a possible fine of up to $25,000.4Justia. Puerto Rico Code 24 2401 – Prohibited Acts (A) Penalties
- Distribution of Schedule I non-narcotics (cannabis) is a felony carrying a fixed twelve-year prison term, with a range of five to twenty years, plus a possible fine of up to $20,000.4Justia. Puerto Rico Code 24 2401 – Prohibited Acts (A) Penalties
When Federal Charges Take Over
A case that begins with a local arrest can be adopted by federal prosecutors when it involves substantial quantities, organized crime, or interstate or international elements. The switch matters because 21 U.S.C. § 841 attaches mandatory minimums to specific drug quantities:
- Cocaine, 500 grams to 4,999 grams: 5-year mandatory minimum, 40-year maximum for a first offense. The minimum rises to 20 years if death or serious injury results.5Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A
- Cocaine, 5 kilograms or more: 10-year mandatory minimum, life maximum for a first offense; 15-year minimum after a prior serious drug felony.5Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A
- Heroin, 100 grams to 999 grams: 5-year mandatory minimum, 40-year maximum for a first offense.5Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A
- Heroin, 1 kilogram or more: 10 years to life for a first offense.5Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A
Two or more prior convictions for a serious drug felony or serious violent felony trigger a 25-year mandatory minimum on a subsequent federal trafficking charge, and federal fines can reach $10 million for an individual.5Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A Federal enforcement in Puerto Rico is substantial: the DEA’s Caribbean Field Division is headquartered in San Juan and works with the Coast Guard, DHS, and DoD on maritime and air interdiction.6DEA.gov.

Medical Cannabis: The One Legal Exception
Act 42-2017 legalized medical cannabis in Puerto Rico. Recreational use is still illegal. To use the program, a patient needs certification from a physician licensed in Puerto Rico confirming a qualifying medical condition, and then a patient identification card from the Department of Health.
Qualifying conditions are broad and include chronic pain, cancer and cachexia, epilepsy, PTSD, Alzheimer’s and Parkinson’s disease, anxiety and depression, HIV/AIDS and hepatitis C, multiple sclerosis and persistent muscle spasms, fibromyalgia, migraines, glaucoma, Crohn’s disease, ALS, and any incurable or advanced disease requiring palliative care.
Registered patients may possess up to a 30-day supply. The daily limit is one ounce of flower or eight grams of THC in concentrate or edible form. Smoking flower is prohibited. Permitted methods include vaporization, capsules, edibles, oils, oral drops, topical creams, transdermal patches, and suppositories. Home cultivation is not allowed, and only licensed cultivators can grow cannabis for the medical market.
Puerto Rico recognizes valid medical cannabis cards from other U.S. states and territories. Visitors can buy at most dispensaries by presenting the card and a government-issued ID, or obtain a temporary 30-day card through a consultation with a local certified physician. The same possession limits apply.
Job Protections for Patients
Act 15-2021 amended the medical cannabis law to prohibit employment discrimination against registered patients. An employer generally cannot refuse to hire, fire, or penalize a worker solely because that worker is an authorized patient who has disclosed the status.
The protection has meaningful exceptions. An employer can still take action if the employee’s cannabis use poses a genuine safety risk to people or property, if it interferes with essential job duties, if accommodating the employee would jeopardize the employer’s federal licenses, permits, certifications, or funding, or if the employee uses or possesses cannabis at work or during work hours without written authorization. The federal-compliance carve-out is the broad one: it reaches most workers in federally regulated industries or on federal contracts.
Driving Under the Influence of Drugs
Driving while impaired by any controlled substance is a misdemeanor. The statute does not set a numerical concentration threshold the way alcohol law does; it prohibits operating a vehicle while “under the effects” of any narcotic, cannabis, stimulant, depressant, or other controlled substance.7Justia. Puerto Rico Code 9 5204 – Penalties An officer who suspects drug impairment issues a summons, prevents the driver from continuing, and takes them to the nearest police station, where they must remain until the officer determines they are no longer impaired.
A first offense carries a fine of $300 to $500, mandatory attendance at a certified orientation program, and license suspension of up to 30 days; failing to complete the program can add 5 to 15 days of jail. A second offense carries a fine of $500 to $750, 15 to 30 days in jail, and a one-year license suspension, with the court able to impose an ignition interlock device, screening and treatment, or community service.7Justia. Puerto Rico Code 9 5204 – Penalties
Holding a valid medical cannabis card does not create an exception. If you are impaired at the wheel, the penalties apply regardless of whether the substance was legally obtained.
Drug Court as an Alternative to Prison
Puerto Rico’s Judicial Branch runs a Drug Court Program aimed at non-violent offenders whose crimes are tied to substance use. To qualify, a defendant must be charged with a non-violent felony, plead guilty, have a diagnosed substance or alcohol use disorder, and have little or no prior criminal history. The offense charged must be causally related to the addiction.8Judicial Branch of Puerto Rico. Drug Courts
Participants enter treatment under intensive court supervision, appearing before a judge at regular hearings. Good progress earns incentives such as reduced supervision. Violations can bring tighter supervision, an extended term, or removal from the program and transfer to a correctional facility.
Successful completion carries a significant reward. The judge dismisses the case, the police return the participant’s photos and fingerprints, and a person with no prior convictions can obtain a clean criminal record certificate.8Judicial Branch of Puerto Rico. Drug Courts For a first-time possession defendant, this is often the most consequential option in the case.
Clearing a Drug Conviction From Your Record
Puerto Rico allows expungement of certain criminal records under Law No. 254 of 1974. A person can request removal of an offense provided they have not committed further crimes and have no additional convictions. A statutory waiting period applies before a request can be filed, and its length depends on the offense.9Judicial Branch of Puerto Rico. Expungement of Criminal Record Drug Court graduates receive a clean record through that program itself and do not go through the standard expungement process.
