Is weed legal in St. Martin? No. Cannabis is illegal on both halves of the island, but the two sides enforce that prohibition very differently: the Dutch side (Sint Maarten) typically confiscates small personal amounts and issues a warning, while the French side (Saint Martin) applies France’s national drug laws and hands out fixed fines starting at €200. There are no licensed dispensaries, no coffee shops, and no legal retail sales anywhere on the island.
The Dutch Side: Illegal, Loosely Enforced
Despite the Netherlands connection, Sint Maarten does not follow Amsterdam’s tolerance model. The Opium National Ordinance of 1960 classifies cannabis as a controlled substance alongside harder drugs.1Lokale wet- en regelgeving. Landsverordening van de 28ste Maart 1960 – Opium Ordinance
Enforcement for personal-use quantities is lighter than the statute suggests. A directive from the Caribbean Prosecutor General’s Office, effective December 1, 2018, tells prosecutors that people found with up to 25 grams of marijuana for personal use should have the drugs confiscated and receive a warning rather than a court date.
A warning is not guaranteed, though. The U.S. State Department warns that Sint Maarten’s drug possession laws “are enforced rigorously, including against tourists in possession of marijuana for personal use.”2Department of State. Sint Maarten International Travel Information Prosecutorial discretion runs in both directions.
Medical cannabis exists on paper. Sint Maarten’s Inspectorate VSA announced a policy in 2019 under which cannabis-derived products for approved conditions require a prescription from an authorized local practitioner and are available only through pharmacies. Foreign prescriptions are not recognized, and the program is narrow compared to U.S. medical marijuana regimes.
The French Side: Fixed Fines Under French National Law
Saint Martin is a French overseas collectivity, so French national drug law applies in full. Since September 2020, police can issue a fixed fine of €200 to anyone caught with small quantities of cannabis (up to 50 grams) instead of pursuing criminal prosecution. Paying within 15 days reduces the fine to €150; waiting more than 45 days raises it to €450.3Library of Congress. France: Possession of Small Amounts of Drugs Now Subject to Fines
The fixed-fine system is designed for minor encounters. Police can still pursue traditional criminal charges, particularly for repeat offenders or when drug possession accompanies other offenses.
The Invisible Border Is Not a Loophole
St. Martin has no passport checks, customs posts, or visible checkpoints between its two halves. Under the 1648 Treaty of Concordia, people and goods move freely across the island, and most road crossings are marked by nothing more than a small monument or flag. You can cross back and forth several times a day without realizing it.
That open border creates a specific legal risk. Cannabis that would draw only a warning on the Dutch side becomes a fineable offense the instant you step onto French territory. Carrying cannabis from one side to the other technically constitutes international drug transport, which both jurisdictions treat far more seriously than simple possession. The uniform-looking island hides two different legal systems, two different penalty structures, and two different currencies for fines.
Enforcement at ports of entry is active. Princess Juliana International Airport on the Dutch side and Grand Case Airport on the French side both screen passengers and use drug-sniffing dogs periodically. Cruise passengers are not exempt: customs officers at the Sint Maarten cruise terminal have seized drugs and issued fines to travelers coming off ships.
CBD, Hemp, and Semi-Synthetic Cannabinoids
The CBD rules diverge almost as sharply as the cannabis rules.
On the Dutch side, the Inspectorate VSA evaluates CBD products to decide whether they qualify as medicine. Products that do are restricted to pharmacy sales and may require a prescription. Hemp seed oil generally falls outside the Opium Ordinance, but the Inspectorate has said it will restrict even hemp seed oil to pharmacies if products are found to contain undeclared THC. Casual over-the-counter CBD shopping is not how it works in Sint Maarten.
On the French side, CBD products derived from hemp with less than 0.3% THC are legal, in line with EU hemp standards, and are available in retail settings. One trap matters for American travelers: France banned a list of semi-synthetic cannabinoids as of June 2024, including delta-8 THC, HHC, THCA, H4-CBD, and THCP. Products containing any of these are treated as narcotics on the French side, regardless of how they are labeled or marketed back home.
Penalties Beyond Personal Use
Serious offenses are punished severely on both sides.
In Sint Maarten, drug trafficking and large-scale production can bring lengthy prison sentences, and the most serious offenses carry the possibility of life imprisonment.4Department of State. Sint Maarten Country Report The Penal Code’s highest fine category reaches ANG 1,000,000 (roughly $559,000 USD).5Library of Congress. Sint Maarten: New Criminal Code
On the French side, the statutory ceilings are:
- Cultivation or production, including a single plant for personal use: up to 20 years in prison and fines up to €7.5 million
- Sale or distribution: up to 10 years in prison and fines up to €7.5 million, with enhancements when sales involve minors or occur near schools6European Union Drugs Agency. France Country Drug Report
- Driving under the influence of drugs: up to 2 years in prison and a €4,500 fine7Service Public. Drugs While Driving
Those maximums target organized trafficking, but French prosecutors have broad discretion in how drug offenses are charged. Foreign nationals convicted of drug trafficking on the French side may also face a multi-year ban from French territory, which covers metropolitan France and all overseas territories, not just Saint Martin.
Taking Cannabis Back to the United States
Even travelers who avoid trouble on the island face a federal problem on the way home. U.S. Customs and Border Protection has made clear that marijuana possession remains illegal under federal law regardless of any state-level legalization, and crossing an international border with any amount can mean seizure, fines, and arrest.8U.S. Customs and Border Protection. Baltimore CBP Reminds Global Entry Members That Marijuana Possession Still Violates Federal Law
Trusted Traveler Program members face an extra consequence most people never think about. CBP has revoked Global Entry memberships over amounts as small as two grams, with a $500 penalty attached. Losing Global Entry or TSA PreCheck over a vacation souvenir is a real and recurring outcome.
