In Costa Rica, the legal drug landscape centers on alcohol and tobacco as lawful but regulated substances, while prescription medications remain lawful when obtained with a valid prescription and sourced from licensed pharmacies. Caffeine-containing products and most over-the-counter medicines are also lawful and widely available, though labeling and dosage rules apply. Costa Rica enforces strict controls on narcotics, psychotropics, and cannabis, making possession, purchase, or sale without authorization illegal and subject to criminal penalties. This overview outlines the main categories, limits, and practical rules to help you align with local law.
Key Legal Substances and Rules
Alcohol and Tobacco
Alcohol is legal and widely sold in licensed venues, with a national excise tax and minimum legal drinking age typically set at 18, though enforcement can vary by location. Tobacco is legal but restricted in public indoor spaces and around schools, and cigarette packaging must carry graphic health warnings. Retail hours and taxation apply, and driving with measurable blood alcohol concentration above the legal limit is an offense.
Prescription Medications and Over-the-Counter Drugs
Prescription medications are legal when prescribed by a licensed Costa Rican doctor and dispensed by a registered pharmacy. Travelers should carry original packaging and a copy of the prescription for controlled medications, as the Ministry of Health and the Judicial Investigation Agency verify authenticity. Common over-the-counter medicines, including basic pain relievers and antihistamines, are generally available without restriction in pharmacies, but labels and strength limits are enforced.
Controlled and Restricted Substances
Narcotics, psychotropics, and cannabis are controlled under Costa Rican law and international treaties. Possession, purchase, sale, or cultivation without authorization is illegal and can result in arrest, prosecution, fines, and imprisonment, regardless of quantity. Importing controlled substances without prior authorization is prohibited, and border controls may include searches and required documentation for medications containing controlled ingredients.
Practical Guidance for Travelers and Residents
- Carry prescriptions and original packaging for any controlled medication, and verify with a licensed physician and pharmacy.
- Do not purchase, share, or use cannabis or other illicit drugs, as penalties are severe and enforcement is active.
- Limit alcohol consumption in public spaces, respect local noise ordinances, and avoid driving under the influence.
- Check ingredient labels and dosage limits for over-the-counter medicines, especially when combining products.
- When in doubt, consult a licensed Costa Rican doctor or pharmacist before using or transporting unfamiliar substances.
