Marijuana in Belgium: what is allowed and what are the consequences (2026)

Belgium is an example of a country where the most important document is not a law. The threshold of three grams, repeated in every tourist guide, comes from a prosecutorial directive, which is a completely different tool than a criminal provision.

The difference has practical consequences, and this is where we begin. Below is what follows directly from the text of the directive and from the position of the Belgian Medicines Agency; where sources are silent, we do not add anything.

Legal status checked on September 4, 2026, in the text of the directive and on the website of the Belgian Medicines Agency. This is a description of regulations, not legal advice.

Is possession of marijuana in Belgium punishable?

It has not been legalized, but an adult who has an amount considered for personal use ends up at the very bottom of the prosecution priority list. The police then prepare a simplified protocol, marked with the abbreviation PVS, and this does not enter either the regular prosecutorial circulation or the statistics of drug crime prosecution.

It is worth naming what this document is. The joint directive of the Minister of Justice and the College of Prosecutors General binds the prosecution, not the citizen or the court. It tells officials how to set priorities, not citizens what is allowed.

The effect for the passerby is nonetheless palpable. The case does not enter the regular procedure, so it does not start with an arrest and questioning as a suspect of a drug crime. Formally, however, possession remains an illegal act, and the directive can be changed without changing the law.

Belgium also does not operate shops or establishments where marijuana could be purchased. The lack of prosecution at the bottom of the priority list applies only to possession by an adult, and not to sales, which remain a crime in the regular procedure.

This distinction disappears in most compilations that list Belgium alongside countries with true decriminalization. How the same boundary runs elsewhere is shown by our map of marijuana legality.

How much marijuana is allowed in Belgium?

Three grams or one cultivated plant. With this amount, if there are no aggravating circumstances and no public order disturbance, personal use is presumed. The directive formulates this as a maximum of three grams or one cultivated plant, and it remains at that single number.

The presumption works both ways, and this is its essence. Below the threshold, the officer assumes personal use until something contradicts that. Above the threshold, the assumption disappears, and the case returns to the normal procedure, without the need to prove anything additional.

Aggravating circumstances can invalidate the threshold even with a smaller amount. The directive mentions cultivation of a commercial nature, the presence of minors, and signs of further sales. Each of these moves the case to the criminal route regardless of how much was found.

The practical conclusion is simple: the threshold describes a typical situation, not a subjective right. Three grams in the pocket is different from three grams divided into portions next to a scale, even though the weight is the same.

It is worth adding that the directive speaks of an adult person. In the case of a minor, the entire priority structure does not work, and the presence of a minor at the act is separately mentioned as an aggravating circumstance.

What are the consequences of exceeding the threshold in Belgium?

With an amount within the threshold and without aggravating circumstances, the case ends with a simplified protocol. The substance is not subject to seizure unless the perpetrator voluntarily hands it over. This solution is rare: in most countries in this compilation, seizure occurs always, regardless of the further course of the case.

The lack of seizure can be read as permission, but it is not. The directive describes how the police handle the case, and does not change the qualification of the act or create a right to possess.

Aggravating circumstances change everything at once. Commercial cultivation, the presence of minors, and signs of further sales move the case to the regular criminal route, where the penalty is determined by law, not by the priority of prosecution.

For the traveler, this means an unclear situation. The risk with a small amount is realistically low, but it does not zero out and does not result from any guarantee provision. It depends on the officer’s assessment, which also includes behavior in public places.

There is also no fee or fine that could be paid on the spot to close the case. The simplified protocol is a police document, not a financial penalty.

Does Belgium have a medical marijuana program?

Not in the form of dried cannabis. Belgium does not have a medical marijuana program based on cannabis flowers. Only one cannabis drug, Sativex, is allowed for circulation, reimbursed only for multiple sclerosis and only for muscle stiffness, meaning in one indication, and not in a wide range of conditions.

Outside of that indication, the drug may be made available through another route. The Federal Medicines Agency describes a program of urgent medical need, in which access is requested by the attending physician. This is an exceptional pathway, initiated for a specific patient, not a parallel access program.

Separately, pharmacies operate that can prepare prescription drugs with CBD. This is a different category than dried cannabis and different from a registered drug, which we discuss in the section on the status of CBD.

For a patient from Poland, the practical conclusion is that Belgium is not a country where a prescription for dried cannabis can be fulfilled. There simply is no program that could serve it.

It is worth distinguishing two things that are most often confused in discussions about Belgium: a registered drug goes to the pharmacy as a ready product, while a prescription drug is made there for a specific prescription. Dried cannabis is neither one nor the other.

Is it allowed to cultivate cannabis for personal use in Belgium?

One plant falls within the threshold for personal use from the directive and is subject to the same lowest priority for prosecution as three grams of dried cannabis. The legislator has thus treated a single plant as a supply for oneself, not as the beginning of production, as long as nothing indicates sales.

The boundary is sharp. Cultivation for commercial purposes is explicitly listed as an aggravating circumstance, and then the priority of prosecution ceases to matter, and the case goes through the regular procedure.

The directive does not define how to recognize commercial intent, and this is its weak point. The assessment belongs to the officer, and in practice, accompanying circumstances determine: the scale of cultivation, equipment, and what is found nearby.

Note that this refers to a controlled cannabis plant, not to industrial hemp. These are two different legal categories, and consumer products from the latter group, such as hemp oils, are subject to different regulations.

The directive also says nothing about where the plant can stand or whether it can be displayed. It regulates only the priority of prosecution, so other questions are resolved by regular criminal law and the practice of the local prosecutor’s office.

What is the status of CBD in Belgium?

Belgian pharmacies can prepare prescription drugs based on CBD, provided that the THC content does not exceed one-tenth of a percent. This is a pharmacy route, not a shop route: it refers to a preparation made on prescription by a pharmacist, not to a product sitting on a store shelf.

From May 1, 2025, such preparations are subject to reimbursement, but in a very narrow scope. The condition is that they are administered in combination with clobazam, and the indications are Dravet syndrome and Lennox-Gastaut syndrome, meaning two severe forms of drug-resistant epilepsy.

Reimbursement is subject to additional conditions, which the agency does not summarize in one sentence. The source used here indicates the fact of reimbursement and its scope, so we will stop here and not add details from other studies.

The conclusion for the reader is that CBD has the status of a drug in Belgium when it is produced in a pharmacy and reaches the patient on prescription. The status of consumer products is a separate issue, which the sources used here do not resolve.

Do not confuse reimbursement with availability. A reimbursed preparation in two epilepsy syndromes still requires a prescription and is still produced in a pharmacy, which means it cannot simply be purchased while traveling through Belgium.
