Police Control and Medical Marijuana: What Documents Must a Patient Carry in 2026?

Traffic control is a situation where no one has time to read the regulations. A medical marijuana therapy patient carries a substance whose possession without legal basis is a crime, and that legal basis is a prescription filled at a pharmacy. This text clarifies three things: what exactly you need to have with you, what the officer is allowed to do, and what you can refuse. For each statement, we provide the regulation along with the current consolidated text so that it can be verified without our mediation. Separately, we describe the boundary that most people stumble over: a prescription legalizes possession of the medication but does not legalize driving after its use. These are two different matters and two different criminal regulations.

KEY INFORMATION
- A prescription filled at a pharmacy excludes the mark “contrary to the provisions of the Act” from art. 62 of the Act on Counteracting Drug Addiction (consolidated text Journal of Laws 2023 item 1939).
- A prescription for a narcotic drug is valid for 30 days from the date of issuance (art. 96a sec. 7 point 4 of the Pharmaceutical Law, consolidated text Journal of Laws 2026 item 612).
- A one-time prescription can cover a supply for a maximum of 90 days of use (regulation of the Minister of Health of September 11, 2006, consolidated text Journal of Laws 2025 item 1678).
- You have the right to refuse explanations (art. 175 sec. 1 of the Code of Criminal Procedure) and request contact with a lawyer after being detained (art. 245 sec. 1 of the Code of Criminal Procedure).
- A prescription does not exclude liability for driving under the influence of a narcotic substance (art. 178a sec. 1 of the Penal Code).

Can a patient with a prescription legally carry cannabis herb?

Yes. Art. 62 sec. 1 of the Act of July 29, 2005 on Counteracting Drug Addiction (consolidated text Journal of Laws 2023 item 1939) penalizes possession of narcotic drugs only when it occurs contrary to the provisions of the Act. A prescription issued by a doctor and filled at a pharmacy is the legal basis for possession, so this mark is not fulfilled.

The right to such a prescription was opened by art. 33a of the Act, added by the Act of July 7, 2017 (Journal of Laws 2017 item 1458), which came into force on November 1, 2017. The provision allows that cannabis other than fiber and extracts from it can be a pharmaceutical raw material intended for the preparation of prescription drugs, after obtaining permission from the President of the Office for Registration of Medicinal Products. This is an important distinction: the patient does not buy a ready-made drug off the shelf, but rather a raw material issued on prescription.

It is also worth knowing the other side of this provision, as the officer certainly knows it. Possession without legal basis is punishable by imprisonment of up to 3 years (art. 62 sec. 1). If the object of the act is a significant amount, the perpetrator is subject to a penalty of 1 to 10 years (sec. 2). In the case of lesser importance, a fine, restriction of freedom, or imprisonment of up to 1 year is applicable (sec. 3). In the case of a small amount intended for personal use, the proceedings can also be discontinued before the issuance of a decision to initiate an investigation or inquiry (art. 62a).

If you are just starting your journey to legal therapy, we have described it separately in the text how to become a medical marijuana patient in Poland.

What documents must a medical marijuana patient carry?

The complete set consists of three elements: proof of the legal source of the medication, proof of its legal issuance, and proof of identity. No regulation explicitly requires carrying them together, but they determine whether the officer will conclude the action on the spot or investigate further. The table below shows what each of them specifically confirms.

A prescription can be in electronic or paper form, and both have the same validity (art. 95b sec. 1 of the Pharmaceutical Law, consolidated text Journal of Laws 2026 item 612). For an e-prescription, a screen of the app with the code, date of issuance, and the issuer’s data is sufficient.

There is one catch with the mObywatel document that few people know about. The Act of May 26, 2023, on the mObywatel application (Journal of Laws 2023 item 1234) recognizes the obligation to present an identity document as fulfilled when identity is confirmed based on the mObywatel document (art. 7 sec. 4). However, sec. 5 excludes it when crossing the state border and everywhere else where it does not provide the required level of certainty. Therefore, a plastic ID still makes sense in your wallet.

What must a prescription for cannabis herb contain?

A prescription for a preparation containing a narcotic drug has one more requirement than a regular one. In addition to the data from art. 96a sec. 1 of the Pharmaceutical Law, it specifies the total amount of the narcotic drug or the amount expressed in dosage units along with the size of the dose, with the amount being written out in words on a paper prescription. This is stipulated in sec. 6 sec. 1 of the regulation of the Minister of Health of September 11, 2006.

The second principle concerns the content of the document itself. Only one preparation containing narcotic drugs or psychotropic substances can be prescribed on one prescription, and no other medicinal products may be prescribed on it (sec. 6 sec. 2). Therefore, if you are taking several medications, the herb will always come on a separate prescription. This is normal practice, not a signal that something is wrong.

The method of dosing must be entered. The regulation of the Minister of Health regarding prescriptions (consolidated text Journal of Laws 2025 item 604) stipulates that in the absence of such an entry, the pharmacy cannot dispense any amount of a product containing a narcotic drug. The realization of the prescription includes its assessment and the dispensing of the medication, and for a paper prescription, also confirmation of realization on the reverse with the name and surname of the person dispensing it and their signature.

For traffic control, this results in a very practical matter. The data on the pharmacy label and the data on the prescription must match regarding the name of the raw material and the amount, as this is the only pair of documents that the officer can compare on the spot. If the dosage has changed along the way and you are carrying packaging from a previous realization next to a new prescription, explaining will take much more time. It is simplest to keep the packaging and the prescription from the same realization together.

How long is a prescription valid and how much herb am I allowed to carry?

A prescription for narcotic drugs is valid for 30 days from the date of issuance or from the date marked on it as “from the day” of realization. This follows directly from art. 96a sec. 7 point 4 of the Pharmaceutical Law. For regular medications, the term is much longer, so this is the first thing to check before traveling.

The amount is limited by another provision. According to sec. 7 sec. 1 of the regulation of the Minister of Health of September 11, 2006, regarding narcotic drugs, psychotropic substances, category 1 precursors, and preparations containing these substances (consolidated text Journal of Laws 2025 item 1678), a prescription for preparations containing narcotic drugs of group I-N may concern an amount not exceeding the patient’s demand for a maximum of 90 days of use. Sec. 2 allows issuing up to three prescriptions for consecutive periods, also totaling up to 90 days.

Polish law does not know a separate limit “for pocket”. There is no provision stating how many grams you are allowed to carry on your way to work. However, the concept of a significant amount from art. 62 sec. 2 is important, as it shifts the matter to a more severe type of crime. The Supreme Court in its judgment of May 7, 2013 (case III KK 25/13) accepted that a significant amount is one that is sufficient to intoxicate at least several dozen addicted individuals. The law does not specify any weight threshold, and the numbers circulating in online guides have no basis in the regulation.

The practical conclusion is simple. You carry with you as much as results from the current dosage for the next few days, and leave the rest of the supply at home. The rest remains in the original packaging along with the label.

What does a police control look like step by step?

A typical process has four stages and, with a complete set of documents, ends at the second. Police officers have the right to identify individuals to establish their identity based on art. 15 sec. 1 point 1 of the Act of April 6, 1990 on the Police (consolidated text Journal of Laws 2025 item 636). In traffic control, this is supplemented by the authority from the Road Traffic Law.

An ununiformed police officer, performing actions such as detaining a person or searching, is obliged to show their service ID in a way that allows reading and noting its number, issuing authority, and the officer’s name (art. 61 sec. 1 of the Police Act). For other administrative and order-related actions, they do this at the request of the citizen (sec. 2). Noting this data is not an act of hostility, but a normal safeguard for both parties.

Conversations with patients reveal a simple rule: the action takes less time the sooner the statement “I am a patient, here is my prescription and packaging from the pharmacy” is made. You do not need to explain the diagnosis or treatment process.

What rights does a patient have during police actions?

Rights are described in the Code of Criminal Procedure (consolidated text Journal of Laws 2026 item 490). The two most important are the right to remain silent and the right to a defender, but the list is longer, and it is worth knowing it in full before it is needed.

A protocol is required, among other things, for searching a person and seizing items (art. 143 sec. 1 point 6 of the Code of Criminal Procedure). Therefore, if the officer takes the herb into custody, a document is created, the content of which you can read and supplement with your own statement. The deadline for filing a complaint is 7 days (art. 460 of the Code of Criminal Procedure).

The right to remain silent is often misunderstood. It does not mean that you should refuse to provide data when being identified, as that is a separate action with a different basis. It means that you do not have to talk about circumstances that could incriminate yourself.

What not to do during a control to avoid adding charges?

The most costly mistakes in this situation do not concern the herb but behavior towards the officer. Three provisions turn nervousness into a separate criminal case, completely independent of whether your prescription is in order.

Insulting a public officer during and in connection with the performance of their official duties is punishable by a fine, restriction of freedom, or imprisonment of up to 1 year. This is art. 226 sec. 1 of the Penal Code (consolidated text Journal of Laws 2025 item 383) and only this one. In guides circulating online, art. 224 is sometimes attached to insult, but that is a completely different provision.

Art. 224 sec. 1 concerns exerting influence through violence or unlawful threats on the official actions of the authority, and sec. 2 concerns using violence or unlawful threats to force the officer to undertake or refrain from a legal official action. The penalty can reach 3 years of imprisonment. The difference is not academic: one is words, the other is violence or threats.

Separately stands the violation of the bodily integrity of an officer during or in connection with the performance of their official duties, punishable by a fine, restriction of freedom, or imprisonment of up to 3 years (art. 222 sec. 1 of the Penal Code). It is worth knowing that sec. 2 of this provision allows the court to exceptionally mitigate the penalty or even refrain from imposing it if the act was provoked by the officer’s inappropriate behavior. However, this is a court’s assessment after the fact, not a shield at the scene of the incident.

The third provision concerns identity itself. Deliberately misleading an authority authorized to identify regarding one’s own or another person’s identity, as well as failing to provide such information contrary to the obligation, is an offense under art. 65 sec. 1 and 2 of the Code of Offenses (consolidated text Journal of Laws 2025 item 734), punishable by restriction of freedom or a fine. You always provide your data. You can remain silent about other matters.

Can the police test a patient’s saliva or blood?

Yes, and they do not need your consent for this. Testing to determine the presence of a substance acting similarly to alcohol is first conducted using a method that does not require laboratory testing, namely a saliva test (art. 129j sec. 1 of the Road Traffic Law, consolidated text Journal of Laws 2024 item 1251). Sec. 4 stipulates that testing can also be conducted in the absence of the tested person’s consent, after informing them about it.

Blood or urine come into play in two situations. When the person’s condition prevents non-laboratory testing or when they refuse to undergo such testing (sec. 2), as well as as a consequence of saliva testing or when it is not possible to perform it (sec. 3). Refusal to blow into the device does not close the matter, but rather transfers it to the laboratory level.

The methods and substances detected are described in the regulation of the Minister of Health of July 16, 2014 (Journal of Laws 2014 item 948). Sec. 1 lists tetrahydrocannabinols among the substances acting similarly to alcohol. Sec. 3 sec. 4 point 4 provides for a detection limit for blood of delta-9-THC at 1 ng/ml, and sec. 4 sec. 4 point 4 for urine a limit of 20 ng/ml for the metabolite 11-nor-9-carboxy-THC.

These numbers are often misread, so let’s repeat: these are the detection limits of the laboratory method, not statutory thresholds of liability. Polish law does not specify a concentration for THC analogous to blood alcohol levels. We discussed how long the substance can be detected in the text about the detection time of cannabinoids in urine.

Does a prescription protect against liability for driving under THC?

No, it does not provide any protection. Art. 178a sec. 1 of the Penal Code penalizes driving a motor vehicle under the influence of a narcotic substance with a penalty of imprisonment of up to 3 years. The provision does not recognize an exception for patients or for medications issued on prescription, just as it does not recognize it for opioids.

In addition to the penalty, there are two mandatory decisions. The court imposes a ban on driving for a period of not less than 3 years (art. 42 sec. 2 of the Penal Code), and the upper limit of such a ban is 15 years (art. 43 sec. 1 of the Penal Code). Upon conviction under art. 178a sec. 1, the court also imposes a monetary penalty for the benefit of the Fund for Victim Assistance and Post-Penitentiary Assistance of at least 5000 PLN (art. 43a sec. 2 of the Penal Code).

Below the threshold of a crime, there is an offense. Driving a motor vehicle in a state after using a substance acting similarly to alcohol is punishable by arrest or a fine of not less than 2500 PLN (art. 87 sec. 1 of the Code of Offenses). The distinction between “under the influence” and “after use” is based on the assessment of the state of the tested person, not on a single number from the laboratory.

How long should you wait? A controlled study involved 30 men who smoked cannabis daily, staying in a closed research ward for up to 33 days, with daily blood sampling. Of the 30 participants, 27 had a positive result for THC, with a median of 1.4 ng/ml. Five percent of the subjects maintained THC levels of at least 1 ng/ml for 12 days, one of eleven was still positive after 26 days, and two of five remained positive after 30 days of abstinence (Bergamaschi et al., Clinical Chemistry, 2013, PMC3717350).

The authors directly link this result to “per se” type regulations, which penalize the mere presence of a substance in the blood. For the patient, this means one thing: with active therapy, safe planning involves refraining from driving, not counting hours from the last dose. There is no window after which the result will definitely be negative. We discussed the related topic in the text about whether you can drive after taking CBD oil.

What to do if an officer questions the prescription?

Start with the complete set of documents presented without comment: prescription or e-prescription code, packaging with a label, identity document. Only if this is not enough do you proceed to external verification. Suggest contacting the pharmacy that filled the prescription, as the pharmacy keeps a record of issued narcotic drugs and can confirm the date and amount.

If doubts remain, request a protocol to be drawn up and use art. 148 sec. 2 of the Code of Criminal Procedure. You have the right to demand that everything concerning your rights or interests be included in it with full accuracy. A sentence like “I have a valid prescription for a pharmaceutical raw material, I presented the prescription, pharmacy packaging, and identity document” takes one line, and later it may be the only trace of what you actually presented.

You do not have to disclose your diagnosis. Medical documentation is protected under the principles of the Patient Rights Act and the Patient Rights Ombudsman, and to prove the legality of possession, a prescription and pharmacy label are sufficient. You can politely brush off questions about the course of the disease.

If the action turns into a detention, you switch to a different track. You demand contact with a lawyer or legal advisor (art. 245 sec. 1 of the Code of Criminal Procedure), and after release, you have the option to file a complaint with the court (art. 246 sec. 1 of the Code of Criminal Procedure). We have noticed in conversations with readers that the most common reason for escalation is not the lack of a prescription but the lack of packaging with a label when transferring the herb to another container.

How to transport medication in Poland and abroad?

In the country, the rule is simple: the herb remains in the original pharmacy packaging with a label, and the label remains legible. Transferring to bags, jars, or boxes from other products removes the only easily verifiable proof of origin and turns a few-minute action into an investigative procedure.

Traveling outside Poland requires a separate document and prior application. When transporting within the European Union, the document is issued by the appropriate provincial pharmaceutical inspector, according to the instructions from the Executive Committee’s decision of December 22, 1994, regarding the certificate provided for in art. 75 for the purpose of transporting narcotic drugs and psychotropic substances. The basis is sec. 5 of the regulation of the Minister of Health of June 8, 2026 (Journal of Laws 2026 item 827), effective from July 12, 2026.

For import or export outside the community area, the document is issued by the Chief Pharmaceutical Inspector at the request of the person receiving the product, to which a prescription or medical documentation is attached (sec. 6 sec. 1). In both cases, the document is issued for a specified period, not exceeding 30 days, and the application must be submitted no later than 15 days before the day of crossing the border. This deadline is crucial, as you cannot request a certificate at the airport.

Before buying a ticket, also check the regulations of the destination country, as a document from the Polish authority does not change the law in force there. We have outlined the procedure step by step in the guide on how to transport medical marijuana abroad.

Where to seek legal assistance after detention?

The first move is yours and follows from art. 245 sec. 1 of the Code of Criminal Procedure. A detained person must be promptly allowed to contact a lawyer or legal advisor upon their request and have a direct conversation with them. In exceptional cases, the detaining officer may stipulate that they will be present during it, but the mere possibility of contact does not depend on their discretion.

If you cannot afford a lawyer of your choice, you can request the appointment of a public defender. The condition is to adequately demonstrate that you cannot bear the costs of defense without compromising your necessary maintenance and that of your family (art. 78 sec. 1 of the Code of Criminal Procedure). This same provision stipulates that prior use of free legal aid cannot be the basis for refusal.

Detention itself is subject to court review. In a complaint, you can demand an examination of its justification, legality, and correctness (art. 246 sec. 1 of the Code of Criminal Procedure), and if the court finds the detention unjustified or illegal, it orders immediate release and notifies the prosecutor and the superior of the authority (art. 246 sec. 3 and 4). For undoubtedly wrongful detention, compensation and redress from the State Treasury are due (art. 552 sec. 4 of the Code of Criminal Procedure).

Write down the lawyer’s number in advance, along with the number of the pharmacy and the attending physician. We do not provide rates for defense, as they depend on the scope of the case and the agreement with the law firm, and any fixed number written here would be fabricated.

Frequently Asked Questions

What documents must I carry as a medical marijuana patient?

Three things: a valid paper prescription or an e-prescription code, the original pharmacy packaging with a label, and an identity document. A prescription for a narcotic drug is valid for 30 days from the date of issuance (art. 96a sec. 7 point 4 of the Pharmaceutical Law, consolidated text Journal of Laws 2026 item 612). The packaging with a label is the simplest proof that the herb comes from a pharmacy.

Does possessing medical marijuana on prescription violate art. 62 of the Act on Counteracting Drug Addiction?

No. Art. 62 sec. 1 of the Act on Counteracting Drug Addiction (consolidated text Journal of Laws 2023 item 1939) penalizes possession of narcotic drugs contrary to the provisions of the Act, and a prescription filled at a pharmacy is the legal basis for possession. Cannabis other than fiber can be a pharmaceutical raw material for prescription drugs under art. 33a of this Act.

Can I refuse to answer a police officer’s questions?

Yes, regarding explanations. Art. 175 sec. 1 of the Code of Criminal Procedure (consolidated text Journal of Laws 2026 item 490) allows you to refuse to answer specific questions or refuse to provide explanations without giving reasons, and art. 74 sec. 1 exempts you from providing evidence against yourself. You cannot refuse to provide data when being identified.

Can the police test my saliva or blood without my consent?

Yes. Art. 129j sec. 4 of the Road Traffic Law (consolidated text Journal of Laws 2024 item 1251) allows testing even in the absence of the tested person’s consent, after informing them about it. Refusal of a saliva test transfers the matter to blood or urine testing (sec. 2). The regulation from 2014 lists tetrahydrokanabinoles among the substances tested.

How much herb am I allowed to carry?

The law does not specify a limit per person. A prescription can cover a supply for a maximum of 90 days of use (sec. 7 sec. 1 of the regulation of the Minister of Health of September 11, 2006, consolidated text Journal of Laws 2025 item 1678). The limit is defined by the concept of a significant amount from art. 62 sec. 2, which the Supreme Court described in judgment III KK 25/13 as sufficient to intoxicate several dozen addicted individuals.

Can I drive after using medical marijuana?

No. Art. 178a sec. 1 of the Penal Code (consolidated text Journal of Laws 2025 item 383) provides for a penalty of imprisonment of up to 3 years for driving under the influence of a narcotic substance, a ban on driving for at least 3 years (art. 42 sec. 2), and a monetary penalty of at least 5000 PLN (art. 43a sec. 2). A prescription does not exclude liability.

Is an e-prescription from the app sufficient during a control?

Yes. The prescription is issued in electronic or paper form, and both forms have the same validity (art. 95b sec. 1 of the Pharmaceutical Law). You show the prescription code along with the date of issuance. The mObywatel document fulfills the obligation to present an identity document but does not authorize crossing the state border (art. 7 sec. 5 of the mObywatel application Act).

What document do I need to travel with the medication abroad?

When traveling within the EU, the document is issued by the provincial pharmaceutical inspector, and for import and export outside it, by the Chief Pharmaceutical Inspector. It is issued for a period not exceeding 30 days, and the application must be submitted no later than 15 days before crossing the border (sec. 5 and sec. 6 of the regulation of the Minister of Health of June 8, 2026, Journal of Laws 2026 item 827).

This article is for informational and educational purposes and does not constitute legal advice. The legal status described in the article is valid as of the date of publication: regulations regarding cannabis may change. Before making a decision, consult a lawyer or current legal acts.
