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

A roadside check 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 basis is a prescription filled at a pharmacy. This text clarifies three things: exactly what you need to carry, what the officer is allowed to do, and what they may refuse. For each statement, we provide the regulation with the current consolidated text so you can verify it without our mediation. Below, we also describe a limit that is easy to overlook: the prescription legalizes possession of the medicine but does not legalize driving after its use. These are two different matters and two different criminal provisions.

KEY INFORMATION
- A prescription filled at a pharmacy excludes the element “contrary to the provisions of the act” from art. 62 of the Act on Counteracting Drug Addiction (consolidated text Dz.U. 2023 item 1939).
- A prescription for a narcotic substance is valid for 30 days from issue (art. 96a sec. 7 point 4 of the Pharmaceutical Law, consolidated text Dz.U. 2026 item 612).
- A supply for a maximum of 90 days of use can be prescribed at once (Ministry of Health regulation of September 11, 2006, consolidated text Dz.U. 2025 item 1678).
- You have the right to refuse explanations (art. 175 par. 1 of the Code of Criminal Procedure) and to request contact with a lawyer after detention (art. 245 par. 1 of the Code of Criminal Procedure).
- The prescription does not exclude liability for driving under the influence of a narcotic substance (art. 178a par. 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 Dz.U. 2023 item 1939) penalizes possession of narcotic substances only when it is 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 element 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 (Dz.U. 2017 item 1458), which came into force on November 1, 2017. The provision allows cannabis other than fiber hemp and extracts thereof to be pharmaceutical raw materials intended for magistral drug preparation, 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 a raw material issued on prescription.

It is also worth knowing the other side of this provision because the officer certainly knows it. Possession without legal basis is punishable by imprisonment 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 from one to 10 years (sec. 2). In case of lesser gravity, a fine, restriction of liberty, or imprisonment up to one year applies (sec. 3). For a small amount intended for personal use, proceedings may be discontinued even before issuing a decision to initiate an investigation or inquiry (art. 62a).

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

What documents must a medical marijuana patient carry?

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

The prescription for cannabis herb today exists only electronically. A magistral drug from cannabis herb has availability category Rpw (art. 33b sec. 4 of the Act on Counteracting Drug Addiction), and a prescription for a product of this category is issued exclusively electronically (art. 95b sec. 1a of the Pharmaceutical Law, consolidated text Dz.U. 2026 item 612). During a check, you show the information about the issued prescription: email, SMS, printout, or view in the Internet Patient Account (art. 96b sec. 2 and 2a). The information itself does not replace the prescription (art. 96b sec. 5), but its printout, email, or view in the Internet Patient Account shows the issue date, doctor, name, and quantity of the medicine, so it can be compared with the label. SMS usually contains only the access code.

There is one catch with the mObywatel document that few know. The Act of May 26, 2023 on the mObywatel application (consolidated text Dz.U. 2026 item 1232) recognizes the obligation to show an identity document as fulfilled when identity was confirmed based on the mObywatel document (art. 7 sec. 4). But sec. 5 excludes it when crossing the state border and everywhere it does not ensure the required level of certainty. Therefore, a plastic ID card still makes sense in the wallet.

What must a prescription for cannabis herb contain?

A prescription for a narcotic substance preparation has one more requirement than a regular one. Besides the data from art. 96a sec. 1 of the Pharmaceutical Law, it states the total amount of the narcotic substance or the amount expressed by the number of dosing units with the dose size. This is stipulated by par. 6 sec. 1 of the Ministry of Health regulation of September 11, 2006. The amount written in words, mentioned by the same provision, applies only to paper prescriptions, which are no longer issued for herb.

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

The dosing method must be entered. The Ministry of Health regulation on prescriptions (consolidated text Dz.U. 2025 item 604) states that without such an entry, the pharmacy cannot dispense any amount of a product containing a narcotic substance. Filling a prescription includes its pricing and dispensing the medicine (par. 5 sec. 1 of this regulation).

For a roadside check, this results in a very practical matter. The data on the pharmacy label and the prescription data must match regarding the raw material name and quantity because this is the only pair of documents the officer can compare on the spot. If the dosing changed along the way and you carry packaging from a previous fill while the Internet Patient Account shows a new prescription, explaining will take much more time. The simplest is to carry the packaging together with the printout of the prescription information from the same fill.

How long is the prescription valid and how much herb can you carry?

A prescription for narcotic substances is valid for 30 days from the issue date. This follows directly from art. 96a sec. 7 point 4 of the Pharmaceutical Law, which, unlike regular prescriptions, does not count this period from the date of dispensing “from the day”. For regular medicines, the period is much longer, so this is the first thing to check before traveling.

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

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

The practical conclusion is simple. Carry as much as results from the current dosing for the coming days, and leave the rest of the supply at home. The entire remainder stays in the original packaging with the label.

What does a police check look like step by step?

The typical course has four stages and ends at the second if you have a complete set of documents. Police officers have the right to identify persons to establish their identity based on art. 15 sec. 1 point 1 of the Act of April 6, 1990 on the Police (consolidated text Dz.U. 2025 item 636). For a roadside check, the right from the Road Traffic Act is added.

An ununiformed police officer performing actions such as detaining a person or searching must show a 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-orderly actions, this is done upon citizen’s request (sec. 2). Noting these data is not an act of hostility but normal protection for both sides.

You do not have to explain your diagnosis or treatment course. It is enough to say you are a patient and show the prescription information together with the pharmacy packaging.

What rights does a patient have during police procedures?

The rights are described by the Code of Criminal Procedure (consolidated text Dz.U. 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 worth knowing in full before it is needed.

A protocol is required, among others, for searching a person and detaining items (art. 143 par. 1 point 6 of the Code of Criminal Procedure). So if the officer takes the herb into custody, a document is created whose content 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 you should refuse to provide data during identification, as this is a separate procedure with a different basis. It means you do not have to talk about circumstances that could incriminate yourself.

What not to do during a check 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 official during and in connection with performing official duties is punishable by a fine, restriction of liberty, or imprisonment up to one year. This is art. 226 par. 1 of the Penal Code (consolidated text Dz.U. 2025 item 383) and only this one. In guides circulating online, art. 224 is sometimes mistakenly linked to insult, but it is a completely different provision.

Art. 224 par. 1 concerns exerting influence by violence or unlawful threat on official acts, and par. 2 concerns using violence or unlawful threat to force an officer to undertake or refrain from a legal official act. The penalty here is up to 3 years imprisonment. The difference is not academic: one is words, the other is violence or threat.

Separately stands the violation of bodily integrity of an officer during or in connection with performing official duties, punishable by a fine, restriction of liberty, or imprisonment up to 3 years (art. 222 par. 1 of the Penal Code). It is worth knowing that par. 2 of this provision allows the court to exceptionally mitigate the penalty or even waive it if the act was caused by improper behavior of the officer. However, this is a court assessment after the fact, not a shield at the scene.

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 failure to provide such information contrary to the obligation, is an offense under art. 65 par. 1 and 2 of the Code of Petty Offenses (consolidated text Dz.U. 2025 item 734), punishable by restriction of liberty or a fine. You always provide data. You may remain silent about other matters.

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

Yes, and they do not need your consent. Testing to determine the presence of a substance acting similarly to alcohol is first conducted by a non-laboratory method, i.e., a saliva test (art. 129j sec. 1 of the Road Traffic Act, consolidated text Dz.U. 2024 item 1251). Sec. 4 stipulates that testing may also be conducted without the tested person’s consent, after informing them.

Blood or urine testing comes into play in two situations. When the person’s condition prevents non-laboratory testing or when they refuse to undergo such testing (sec. 2), and also as a consequence of the saliva test or when it cannot be performed (sec. 3). Refusal of the saliva test does not close the case but transfers it to the laboratory level.

Methods and detected substances are described in the Ministry of Health regulation of July 16, 2014 (Dz.U. 2014 item 948). Par. 1 lists tetrahydrocannabinols among substances acting similarly to alcohol. Par. 3 sec. 4 point 4 sets the detection limit for delta-9-THC in blood at 1 ng/ml, and par. 4 sec. 4 point 4 for urine at 20 ng/ml for the metabolite 11-nor-9-carboxy-THC.

These numbers are often misunderstood, so let’s repeat: these are detection limits of the laboratory method, not statutory thresholds of liability. Polish law does not specify a THC concentration analogous to blood alcohol content. We wrote more about how long cannabinoids remain detectable in urine in the text about cannabinoid detection time in urine.

What does the saliva test detect and what does a positive result mean for a patient?

The saliva test during a check is a screening test. The sample is placed in a device for immunological detection, and tetrahydrocannabinols are on the list of detected substances (par. 1 and par. 2 sec. 1 of the 2014 regulation Dz.U. 2014 item 948). A positive result is not a concentration measurement but a basis for blood or urine testing (art. 129j sec. 3 of the Road Traffic Act).

The prescription does not change the test result because the device detects the substance, not the basis for its possession. A patient taking the medicine must therefore expect a positive result. By itself, it does not decide anything: liability for driving is determined by the assessment of the driver’s condition together with the laboratory result, as discussed in the section on driving after THC.

Confirmation is done by the laboratory. Blood is tested by gas chromatography combined with mass spectrometry or another instrumental method, and two containers of about 5 cm3 each are taken (par. 3 sec. 1 and 2 of the regulation). A protocol is prepared from the tests. It records, among other things, whether blood or urine was tested at the request of the tested person (par. 6 point 11).

The protocol has two fields filled only based on the tested person’s statement: about acceptance or non-acceptance of the substance and about diseases (par. 6 points 2 and 3). The regulation does not impose an obligation to make these statements and does not require providing a diagnosis. Also remember that information about taking a THC medicine does not protect you behind the wheel: the prescription does not exclude liability under art. 87 par. 1 of the Road Traffic Offenses Code or art. 178a par. 1 of the Penal Code.

Can CBD products give a positive result during a police check?

They can if they contain THC because the test detects THC. Cannabidiol itself is not a controlled substance: it is not on the lists of psychotropic substances and narcotics (consolidated text Dz.U. 2024 item 1139, also after changes in 2025 and 2026), so its possession is not subject to art. 62 of the Act on Counteracting Drug Addiction.

In a controlled study on six healthy adults, 100 mg of pure CBD, orally or vaporized, gave one positive screening result out of 218 urine samples and no confirmed laboratory result. Vaporized herb with a CBD predominance containing 3.7 mg THC gave nine positive screening results, four of which were confirmed by LC-MS-MS testing (Spindle et al., Journal of Analytical Toxicology, 2020, PMC7152694).

The study concerned urine, and the roadside test examines saliva, so the numbers cannot be transferred one to one. The conclusion is the same: the result depends on THC in the product, not the CBD label on the packaging. Fiber hemp is by definition plants in which the sum of delta-9-THC and THCA does not exceed 0.3% dry mass (art. 4 point 5 of the Act on Counteracting Drug Addiction), so they may contain THC, but in a small amount. The regulations on driving under the influence and after use (art. 178a Penal Code, art. 87 Road Traffic Offenses Code) do not differentiate the source of the substance. How CBD products perform in drug tests is discussed in the text about CBD and drug tests.

Does a prescription protect against liability for driving after THC?

It does not protect in any way. Art. 178a par. 1 of the Penal Code punishes driving a motor vehicle under the influence of a narcotic substance with imprisonment up to 3 years. The provision knows no exception for patients or medicines issued on prescription, just as it does not for opioids.

Two mandatory rulings are added to the penalty. The court imposes a driving ban for no less than 3 years (art. 42 par. 2), with an upper limit of 15 years (art. 43 par. 1). When convicted under art. 178a par. 1, the court also orders a financial contribution to the Fund for Assistance to Victims and Post-Penitentiary Assistance of at least 5000 PLN (art. 43a par. 2).

Below the crime threshold, 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 not less than 2500 PLN (art. 87 par. 1 of the Road Traffic Offenses Code). The distinction between “under the influence” and “after use” is based on the assessment of the tested person’s condition, not on a single laboratory number.

How long to wait? The controlled study involved 30 men smoking cannabis daily, staying in a closed research ward for up to 33 days, with daily blood sampling. At admission, 27 of 30 participants had a positive THC result, with a median of 1.4 ng/ml. Five percent of subjects maintained THC at at least 1 ng/ml for 12 days; after 26 days, only one of eleven tested negative, 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” regulations, i.e., those punishing mere presence of the substance in the blood. For a patient, this means one thing: safe planning during active therapy involves refraining from driving, not counting hours from the last dose. There is no window after which the result will definitely be negative. A related topic is discussed 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 provided without comment: e-prescription information, packaging with label, identity document. Only when this is insufficient do you proceed to external verification. Suggest contacting the pharmacy that filled the prescription because the pharmacy keeps records of issued narcotic substances and can confirm the date and quantity.

If doubts remain, ask for a protocol to be written and use art. 148 par. 2 of the Code of Criminal Procedure. You have the right to demand that everything concerning your rights or interests be recorded with full accuracy. A sentence like “I have a valid prescription for pharmaceutical raw material, I showed the e-prescription information, pharmacy packaging, and identity document” takes one line and may later be the only trace of what you actually showed.

You do not have to disclose your diagnosis. Medical documentation is protected under the Patient Rights Act and the Patient Rights Ombudsman, and to prove legality of possession, the prescription and pharmacy label suffice. You can politely dismiss questions about the course of illness.

If the procedure turns into detention, you switch to another track. You demand contact with a lawyer or legal advisor (art. 245 par. 1 of the Code of Criminal Procedure), and after release, you have an open path to appeal to the court (art. 246 par. 1).

How to transport medicine in Poland and abroad?

In the country, the rule is one: the herb stays in the original pharmacy packaging with the label, and the label remains legible. Transferring to bags, jars, or boxes from other products removes the only easy-to-check proof of origin and turns a few-minute procedure into an explanatory proceeding.

Traveling outside Poland requires a separate document and prior application. For transport within the European Union, the document is issued by the competent provincial pharmaceutical inspector, according to the instruction from the Executive Committee decision of December 22, 1994, on the certificate provided for in art. 75 for the purpose of transporting narcotic substances and psychotropic substances. The basis is par. 5 of the Ministry of Health regulation of June 8, 2026 (Dz.U. 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 upon the applicant’s request, to which the prescription or medical documentation is attached (par. 6 sec. 1). In both cases, the document is issued for a specified period, not longer than 30 days, and the application must be submitted no later than 15 days before crossing the border. This deadline decides everything because you cannot request the certificate at the airport.

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

Where to seek legal help after detention?

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

If you cannot afford a chosen defender, you may request the appointment of a court-appointed defender. The condition is proper demonstration that you cannot bear the defense costs without detriment to the necessary maintenance of yourself and your family (art. 78 par. 1). The same provision stipulates that prior use of free legal aid cannot be a basis for refusal.

Detention is subject to court control. In a complaint, you may demand examination of its validity, legality, and correctness (art. 246 par. 1), and if detention is found unjustified or illegal, the court orders immediate release and notifies the prosecutor and the superior authority (art. 246 par. 3 and 4). For undoubtedly unlawful detention, compensation and redress from the State Treasury are due (art. 552 par. 4).

Save the lawyer’s number in advance, along with the pharmacy and attending physician’s numbers. We do not provide defense fees here because they depend on the case scope and law firm agreement, and any fixed number here would be fictitious.

Frequently Asked Questions

What documents must I carry as a medical marijuana patient?

Three things: information about the issued e-prescription (printout or view in the Internet Patient Account), the original pharmacy packaging with a label, and an identity document. The prescription for a narcotic substance is valid for 30 days from the date of issue (art. 96a sec. 7 point 4 of the Pharmaceutical Law, consolidated text Dz.U. 2026 item 612). The packaging with the 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 Dz.U. 2023 item 1939) penalizes possession of narcotic substances contrary to the provisions of the act, and a prescription filled at a pharmacy is the legal basis for possession. Cannabis other than fiber hemp may be a pharmaceutical raw material for magistral drugs under art. 33a of this act.

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

Yes, regarding explanations. Art. 175 par. 1 of the Code of Criminal Procedure (consolidated text Dz.U. 2026 item 490) allows refusal to answer specific questions or to refuse to give explanations without giving reasons, and art. 74 par. 1 exempts from providing evidence to one’s detriment. You cannot refuse to provide data during identification.

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

Yes. Art. 129j sec. 4 of the Road Traffic Act (consolidated text Dz.U. 2024 item 1251) allows testing even without the consent of the tested person, after informing them. Refusal of a saliva test transfers the case to blood or urine testing (sec. 2). The 2014 regulation lists tetrahydrocannabinols among the tested substances.

How much herb am I allowed to carry?

The act does not specify a limit per person. The prescription may cover a supply for a maximum of 90 days of use (par. 7 sec. 1 of the Ministry of Health regulation of September 11, 2006, consolidated text Dz.U. 2025 item 1678). The limit is defined by the concept of a significant amount from art. 62 sec. 2, which the Supreme Court in ruling III KK 25/13 described as sufficient to intoxicate several dozen addicted persons.

Can I drive a car after taking medical marijuana?

No. Art. 178a par. 1 of the Penal Code (consolidated text Dz.U. 2025 item 383) provides for imprisonment up to 3 years for driving under the influence of a narcotic substance, a driving ban for at least 3 years (art. 42 par. 2), and a financial penalty from 5000 PLN (art. 43a par. 2). The prescription is not a circumstance excluding guilt.

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

Yes, because there is no other prescription for the herb: a prescription for a drug in category Rpw is issued exclusively electronically (art. 95b sec. 1a of the Pharmaceutical Law). You show the prescription information with the issue date, for example in the Internet Patient Account. The mObywatel document fulfills the obligation to show an identity document but does not authorize crossing the border (art. 7 sec. 5 of the mObywatel application act).

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

For travel within the European Union, 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 no longer than 30 days, and the application must be submitted no later than 15 days before crossing the border (par. 5 and par. 6 of the Ministry of Health regulation of June 8, 2026, Dz.U. 2026 item 827).
