Marijuana in Canada and Uruguay: two legal markets side by side (FAQ)

Canada and Uruguay are often mentioned in the same breath as countries with a legal market, but they operate under two completely different legal frameworks. One is based on a conversion from the annex to the law, the other on a judge’s assessment, to which the law only adds a number.

This post compares both systems point by point, as it is in the comparison that we see why the same word means something different in each. Separately, we correct two common errors that appear in studies about both countries.

What are the differences between the legal markets of Canada and Uruguay?

Both countries have a legal market, but each built it on a different legal idea. Canada has a separate cannabis law, where the limit is public space and a converted amount, and exceeding it remains a punishable act. Uruguay kept the criminal provisions in force and added exemptions from liability and three paths to legal access.

The difference is best seen in who assesses personal use. In Canada, it is done by the number from the annex to the law, while in Uruguay, it is a judge, according to the principles of free assessment, and only after this assessment does the statutory value of forty grams come into play.

Uruguay’s access routes are three, each with its own limit and registration. These are home cultivation, membership clubs, and pharmacy distribution.

Canada’s system, on the other hand, is dual-track. Alongside the adult market, there is a medical program with its own, higher limits, where a patient can grow for themselves or designate another person for this purpose.

The comparison of both countries makes sense precisely because both are often referred to as legalization. How this boundary looks in other countries is shown by our map of marijuana legality.

How much marijuana is allowed in Canada and Uruguay?

The Canadian regulation refers to public space: it is prohibited to possess an amount corresponding to more than thirty grams of dried cannabis there, while at home, the federal law does not set an upper limit for dried cannabis. Uruguay takes a different approach and exempts from liability possession of an amount intended for personal consumption, which the law caps at forty grams.

Canada also has a separate threshold for minors. It is five grams of equivalent, and possession above this value is no longer allowed.

Plants in public places are also separately regulated there. It is prohibited to take even one flowering or budding plant there, and possessing more than four non-flowering plants is prohibited regardless of the location.

The Canadian law also has a provision regarding organizations. An organization cannot possess cannabis in any amount, so the thirty-gram rule applies only to individuals.

In Uruguay, the exemption covers a broader set of behaviors than just holding onto cannabis. Article 31 lists transporting, holding, storing, and possessing an amount intended for personal consumption, and separately exempts holding at home a collection of up to six plants from home cultivation or a collection belonging to a club member.

Why is the Canadian 30 grams not a weight of the product?

Because thirty grams in the Canadian law is an equivalent, not a weight of the product carried. The conversion table is included in annex 3 to the law, where one gram of dried cannabis corresponds to five grams of fresh cannabis or fifteen grams of solid cannabis product.

Further entries in the table diverge even more. One gram of dried cannabis corresponds to 70 grams of non-beverage product, 0.25 grams of concentrate, 570 grams of beverage, and one seed.

The entry about beverages has been separate since 2022, and it is often misquoted. Comparisons provide 70 grams for beverages, which is the value before the amendment, resulting in a limit that is over eight times too low.

When converting thirty grams of dried cannabis, the scale of this difference becomes clear. This gives 450 grams of baked goods, 7.5 grams of concentrate, or 17,100 grams of beverage.

One last note concerns the unit in which the annex counts beverages. It does so in grams, not in milliliters, so converting to liters would require assuming a density that the law does not provide.

Which Uruguayan forty grams is which?

In Uruguay, there are two different forties, and confusing them changes the meaning of the sentence. Forty grams from Article 31 is the amount for which possession is exempt from liability, once and without reference to a period. Forty grams per month is something else, as that is the upper limit for distribution in pharmacies.

The pharmacy forty refers to psychoactive cannabis issued for non-medical use. It is counted per user and per month, so it is a supply limit, not a boundary of what can be possessed.

In addition, there are limits for the other access routes. Home cultivation allows for up to six plants and a harvest from the previous cultivation of up to 480 grams per year, while a membership club counts from fifteen to forty-five members and up to ninety-nine plants.

The annual supply of the club is proportional to the number of members, not fixed. A separate form is the association of medical cannabis patients, which counts from fifteen to one hundred members, mandatorily with a supervising doctor and pharmacist.

The law also states what these numbers refer to, and this definition is often overlooked. Psychoactive cannabis refers to the flowering tops of the female plant, without seeds and without leaves detached from the stem, along with oils, extracts, and preparations with a natural THC content equal to or greater than 1 percent by volume.

How many plants can be grown at home in both countries?

The Canadian federal law allows for four plants at a time in the residence of a person over eighteen years old, while the Uruguayan law allows for six plants grown for personal consumption or shared consumption at home. The Canadian four are counted per home, not per person.

The Canadian regulation states this explicitly. If several adults live at the same address, it is prohibited to cultivate in such a way that there are more than four plants in the home at once.

The place of cultivation is broadly defined in this law. It includes the ground under the building and the ground adjacent to it, including the yard and garden, as well as buildings and structures on that ground, while cultivation outside one’s residence is prohibited.

It should be clearly stated what this number does not determine. Four plants is the federal ceiling, and provinces have their own regulations, which we have not checked in this material, so we do not claim that four plants can be grown throughout Canada.

Uruguay adds a second value to the number of plants, which the Canadian law does not recognize. This is the harvest from the previous cultivation of up to 480 grams per year, and access to seeds intended for such cultivation is mandated by law to be treated in every case as legal activity.

For a reader from Poland, both of these systems are descriptions of foreign law, not instructions. The hemp products available to us, including hemp oils, are a completely separate category of goods.

What are the consequences of exceeding these limits?

In Canada, the penalties are broad, but for small amounts, the law provides for a fine, while in Uruguay, exceeding the home cultivation limit is not automatically a crime. For exceeding the Canadian possession limit, the penalty can be up to five years less one day of imprisonment.

In a simplified procedure, the threat is lower. The fine can reach 5000 dollars or six months, or both penalties at once, while an organization pays up to 100,000 dollars, and for cultivation beyond the limit, the threat can reach fourteen years.

The fine is described in a separate section of the law, and it determines a typical case. The case can be concluded with it if the amount does not exceed the equivalent of fifty grams of dried cannabis or if it concerns the fifth and sixth plants.

The fine itself is 200 dollars, to which is added a payment for victims and administrative fees. Even after losing in court, the fine cannot exceed 200 dollars, and after payment, the record in the court register cannot be used for any purpose that would identify the person as punished under this law.

Uruguayan penalties are outlined according to the act. For producing without permission, the penalty ranges from two to ten years, and for psychoactive cannabis, the law has a separate, milder range: from twenty months of imprisonment to ten years of heavy imprisonment.

The higher threat includes trafficking and transportation. For import, export, transit, distribution, transportation, storage, possession not for personal use, or offering for sale, the penalty ranges from two to twelve years.

However, the most interesting provision concerns exceeding home cultivation limits. The purpose of the harvest is then assessed by a judge according to the principles of free assessment, so the seventh plant does not automatically become a crime; it simply loses the statutory presumption of personal use, and the unauthorized plantation is still subject to destruction.

How does medical access look in both countries?

The Canadian program operates alongside the adult market and has its own, higher limits, while the Uruguayan program is separated from recreational use by a prescription. The Canadian basis is a medical document in which the doctor enters the daily dose in grams of dried cannabis, and from this dose, everything else is calculated.

The patient’s possession limit is calculated from it. It is thirty times the daily dose or 150 grams of dried cannabis, whichever is smaller, and the ceiling of 150 grams applies even if the patient is registered in several places at once.

The patient can also register with the minister to grow for themselves or designate another person for this purpose. The number of plants is calculated using a formula, and this formula reveals the assumptions on which it stands.

For indoor cultivation, a yield of 30 grams of dried cannabis per plant and three cycles per year is assumed, while for outdoor cultivation, 250 grams per plant and one cycle. Additionally, there is a safety multiplier of 1.2 indoors and 1.3 outdoors, which, with a daily dose of 1 gram, gives about five plants indoors and two outdoors.

The Uruguayan medical access runs differently, as it requires permits. Cultivation and harvesting for the purpose of producing medicinal products require prior permission from the institute regulating cannabis, i.e., IRCCA, and remain under its direct control.

For scientific research and therapeutic products, permission is granted by the Ministry of Public Health, and for the cannabis itself, by IRCCA. A separate route is the associations of medical cannabis patients, counting from fifteen to one hundred members, mandatorily with a supervising doctor and pharmacist.

This last route was conceived as temporary. The law gave it three years from the entry into force of the executive regulation, with the possibility of extension by the ministry, as long as there are no available products.

Where in Uruguay is the line for non-intoxicating cannabis?

The Uruguayan law does not regulate CBD by name, but it sets a boundary that determines it. Non-intoxicating cannabis refers to plants and their parts with a THC content of no more than 1 percent, along with derivatives, and is subject to the Ministry of Agriculture, not the institute supervising psychoactive cannabis.

Seeds of non-intoxicating cannabis varieties have their own requirement. Their THC content cannot exceed 0.5 percent, so the boundary for planting material is stricter than for the plant itself.

This one percent is clearly higher than the European thresholds, which are 0.2 or 0.3 percent. The same plant can therefore be non-intoxicating cannabis in Uruguay and material outside this category in Europe.

The material used here does not mention the Canadian side of this issue, so we do not describe it. We provide the Uruguayan boundary and do not supplement it with the Canadian equivalent from secondary sources, as that would be guesswork.

For a buyer in Poland, Polish law determines the outcome, not either of these two values. In our store, you will find hemp oils and other products made from hemp.

How much does legal marijuana cost in a Uruguayan pharmacy?

The price is set by the state, not the seller. According to the IRCCA price list updated in February 2026, a 5-gram package costs from 485 Uruguayan pesos for the ALFA strain to 615 pesos for the ÉPSILON strain. For comparison, in July 2017, when distribution began, the package cost 187 pesos and only two strains were available.

The dried cannabis is issued in unprocessed form: whole dried flower clusters, unground and unpressed, in packages of 5 grams with health warnings. The state also defines the cannabinoid profile of each strain, making this market incomparable to the commercial one.

Tourists will not benefit from this system. The decree ties registration to citizenship or permanent residency, and the pharmacy checks the entry before issuing the package.

The table shows something that the price itself does not convey. The strains differ not only in price but also in declared composition, so the choice in the pharmacy is a choice between profiles, not just between price shelves.

It is worth remembering that the prices are given in Uruguayan pesos and refer to one month. This is a record of the state, not a constant value, so for comparisons with another market, it is only suitable together with the date.

What does the Cannabis Act allow and prohibit in Canada?

It allows adults to possess up to 30 grams of dried cannabis in public and to grow four non-flowering plants, while everything above these thresholds is still treated as a crime. Article 8, paragraph 1, letter a prohibits a person over 18 from possessing in public an amount corresponding to more than 30 grams of dried cannabis.

Letter c establishes a threshold of 5 grams for minors, and letter e prohibits possessing more than four non-flowering or budding plants.

The penalty is often overlooked in descriptions of the Canadian market, but it is significant. Violating these prohibitions is a crime prosecuted by public indictment, and an adult is subject to a penalty of imprisonment for up to five years less one day (Article 8, paragraph 2, letter a, point i). Legalization has thus shifted the boundary but has not abolished it.

Sales are conducted by points licensed by the provinces: in some provinces, state-owned, in others, private. The buyer does not have to be a citizen or resident; it is enough to be of the required age in that province and to have an identity document. Transporting cannabis across the Canadian border remains prohibited in both directions, regardless of how the law treats it in the destination country. Another variant of national legalization, this time within the Union, has been discussed in the text about the German cannabis law.

Have possession cases disappeared in Canada after legalization?

No, they have not disappeared, although they have dropped significantly. According to a report by Statistics Canada from October 29, 2025, in 2024, the police recorded 22 cannabis-related offenses per 100,000 residents, compared to 194 in 2014. The numbers from local police statistics thus describe the market after the change, not the law itself.

This is a decrease of 89 percent, not a drop to zero; the authors attribute it to the majority of the long-term decline in all drug-related crime in Canada (Trends in police-reported drug crime in Canada).

One should also read the story of mass record clearing cautiously. Bill C-93 from 2019 abolished the fee and waiting period for applying for the expungement of a conviction for mere possession of cannabis. A year after its entry into force, as of August 7, 2020, the Parole Board received 467 applications and granted 265 expungements, with a government estimate of 10,000 eligible individuals (materials from Public Safety Canada).

We noticed in this comparison something that is easy to overlook. Less than five percent of those whom the government considered eligible submitted an application. The mere abolition of the fee and waiting period was not enough for people with old convictions to seek expungement, and this is a separate lesson from that about the effects of legalization on the market.

Can marijuana be brought from Canada or Uruguay to Poland?

No, and the responsibility is stricter than most travelers think. A legal purchase in Toronto or Montevideo does not provide any protection on the Polish side of the border, as Polish law ties criminality to the act, not to the law of the country of purchase. A receipt from a licensed store is a document of no significance in Polish control.

The transport is described in Article 55 of the Act on Counteracting Drug Addiction: a fine and imprisonment for up to 5 years, one year in the case of lesser weight, and from 3 to 20 years when the object of the act is a significant amount or when acting for profit.

Upon return, there is also the issue of possession under Article 62, with penalties of up to 3 years, from one year to 10 years for significant amounts, and a fine or one year for lesser weight. Article 62a allows for the case to be dismissed in the case of a negligible amount.

Customs declaration does not create a legal route here. The provision on import does not recognize an exception for amounts intended for personal use, so declaring at customs only changes how early the case begins.

The distance is not a circumstance here. The provision asks about the amount and the act, not about how many hours the flight took or how far the country of purchase is.

The basis is the Act on Counteracting Drug Addiction in the consolidated text Journal of Laws 2023, item 1939. Article 62, paragraph 1 speaks of a penalty of up to 3 years, paragraph 2 of a range from one year to 10 years, and paragraph 3 of a case of lesser weight.

Frequently asked questions

How much marijuana can be possessed in Canada?

In public, no more than an amount corresponding to thirty grams of dried cannabis, and a minor no more than five grams of equivalent. At home, the federal law does not set an upper limit for dried cannabis.

Does the Canadian 30 grams refer to the weight of the product?

No, it is an equivalent calculated from annex 3 to the law. One gram of dried cannabis corresponds to 5 grams of fresh cannabis, 15 grams of solid product, 0.25 grams of concentrate, or 570 grams of beverage.

How much marijuana can be possessed in Uruguay?

An amount intended for personal consumption is considered to be up to forty grams, but this is assessed by a judge according to the principles of free assessment. Separately, holding at home a collection of up to six plants is exempt.

How many plants can be grown at home in Canada and Uruguay?

The Canadian federal ceiling is four plants per home, not per person; provinces have their own regulations, which we have not checked here. Uruguay allows for up to six plants and a harvest of up to 480 grams per year.

What are the consequences in Canada for exceeding the possession limit?

From an indictment up to five years less one day of imprisonment, and in a simplified procedure, a fine of up to 5000 dollars or six months. For the equivalent of fifty grams, the case can be concluded with a 200 dollar fine.

Is the seventh plant a crime in Uruguay?

No, not automatically. After exceeding the home cultivation limits, the purpose of the harvest is assessed by a judge according to the principles of free assessment, so the plant beyond the limit loses the statutory presumption of personal use.

Which country legalized marijuana first?

Uruguay. Law No. 19.172 was promulgated on December 20, 2013, and regulated the production, distribution, and use of psychoactive cannabis. Canada joined on October 17, 2018, when the Cannabis Act came into force.
