Legalization Worldwide: How Other Countries Regulate Cannabis

The debate around cannabis legalization has long since outgrown national borders. Around the globe, countries are experimenting with different regulatory models – from full legalization with commercial markets through decriminalization to strictly controlled medical programmes. This diversity offers a unique opportunity to compare approaches and learn from other countries' experiences. This article analyses the most important international models and places them in the context of the German situation.

## Uruguay: The Pioneer (since 2013)

Uruguay was the first country in the world to fully legalize cannabis in 2013 – for cultivation, sale and consumption. President José Mujica drove the legislation forward, not from a libertarian stance but as a pragmatic measure to combat drug trafficking and strengthen public health. The Uruguayan model rests on three pillars: home cultivation (up to six plants per household), cannabis clubs (15 to 45 members, maximum 99 plants) and sales through licensed pharmacies.

Implementation was initially slow. Only in 2017 – four years after the legislation – did the first pharmacies begin selling cannabis. Prices were set by the state at about 1.30 US dollars per gram, well below the black market price. However, product availability was initially limited: only 17 of over 1,000 pharmacies nationwide opted to sell, as many pharmacists shied away from the effort or feared social stigmatization.

Despite early difficulties, the Uruguayan model shows measurable successes after more than ten years. The black market share has fallen from an estimated 100 percent to below 40 percent. Cannabis use among young people has not increased – a concern frequently voiced by legalization opponents. The number of cannabis-related criminal proceedings has dropped dramatically, relieving the justice system. Critics, however, point to limited product variety, long waiting times at pharmacies and the fact that tourists are excluded from legal purchase.

## Canada: Full Legalization with a Commercial Market (since 2018)

On 17 October 2018, Canada became the first G7 country to fully legalize cannabis. The Cannabis Act (Bill C-45) allows adults aged 18 or 19 (depending on province) to possess up to 30 grams of dried cannabis in public, grow up to four plants per household and purchase from licensed stores or online shops.

The Canadian model differs fundamentally from Uruguay through its commercial approach. Private companies can obtain licences for cultivation, processing and distribution. Regulation operates on two levels: the federal government sets the framework (minimum age, possession limits, criminal law) while provinces and territories determine detailed rules (retail outlets, prices, consumption zones). This leads to considerable regional differences: in Alberta private stores can sell cannabis, while in Quebec and New Brunswick only government-run shops are permitted.

The economic impact is impressive. The Canadian cannabis industry generated revenues exceeding 6 billion Canadian dollars in 2024 and directly or indirectly employs over 150,000 people. Tax revenues from cannabis have totalled over 3 billion dollars since legalization. At the same time, the industry struggles with overproduction, price decline and consolidation – numerous companies founded during the legalization boom have had to file for insolvency.

The health impacts are mixed. Overall consumption rose moderately in the first years after legalization but has since stabilized. On the positive side, the black market share has fallen from an estimated 90 percent to below 30 percent, and consumers have access to quality-controlled products with known THC content. Concerning is the rise in cannabis-related emergency room visits, particularly involving edibles, which can cause overdoses in inexperienced users.

## USA: The Patchwork Model

The situation in the USA is uniquely complex. At the federal level, cannabis remains a Schedule I substance under the Controlled Substances Act – in the same category as heroin. Simultaneously, 24 states and the District of Columbia have legalized cannabis for recreational use, and 38 states allow medical cannabis. This discrepancy between federal and state law creates significant legal uncertainties.

Colorado and Washington were the first states to legalize cannabis by popular vote in 2012. Colorado's model serves as a reference: a tight licensing system regulates cultivation, processing and sales. The state levies a 15 percent excise tax plus sales tax. Since legalization, Colorado has generated over 2.5 billion dollars in cannabis tax revenue, mostly flowing into education, health and infrastructure.

California, the world's largest legal cannabis market, struggles with different problems. The high tax burden (sometimes exceeding 40 percent of the final retail price) and elaborate regulation make it difficult for legal operators to compete with the black market. Estimates suggest that despite legalization, over 50 percent of cannabis in California is still sold on the black market.

The Biden administration initiated the reclassification of cannabis from Schedule I to Schedule III in 2024 – a historic step that does not legalize cannabis at the federal level but facilitates research and reduces tax burdens for legal businesses. Full federal legalization remains politically contentious and unlikely in the short term.

A particularly important aspect of the US debate is social justice. Prohibition disproportionately affected African American and Latino communities: although consumption data show no significant difference by ethnicity, Black Americans were arrested for cannabis offences nearly four times more often than white Americans. Many states have therefore introduced social equity programmes granting preferential access to cannabis licences for people from disproportionately affected communities. Implementation of these programmes, however, has been patchy.

## The Netherlands: Gedoogbeleid – Tolerance Without Legalization

The Netherlands is often mistakenly cited as an example of cannabis legalization. In fact, cannabis is not legal in the Netherlands. The famous gedoogbeleid (tolerance policy) is a pragmatic compromise: the sale of small amounts of cannabis (up to 5 grams per person) in licensed coffeeshops is tolerated, although it formally remains prohibited. Cultivation and supply to coffeeshops – the so-called achterdeur (back door) – are illegal, leading to the paradoxical situation where sales are tolerated but procurement is criminal.

This system has existed since the 1970s and was originally designed as a pragmatic separation of drug markets: by tolerating cannabis coffeeshops, it aimed to prevent cannabis users from coming into contact with the market for harder drugs. The number of coffeeshops has declined over the decades from over 1,500 to approximately 570 (as of 2025), as regulation has been tightened.

The Dutch government launched a pilot project in 2023 to address the back-door problem: in ten selected municipalities, licensed producers may grow cannabis and legally supply it to coffeeshops. This so-called wietexperiment aims to show whether a closed legal supply chain displaces the black market more effectively than the current system. Initial results are expected in 2026.

The Dutch model offers important lessons. On one hand, decades of tolerance policy have shown that open availability of cannabis does not automatically lead to exploding consumption – usage rates in the Netherlands are in the European midfield. On the other hand, it demonstrates the limits of a half-hearted solution: without a legal supply chain, organized crime remains embedded in production.

## Thailand: From Strictest Prohibition to Liberalization (since 2022)

Thailand made one of the most radical turnarounds in global cannabis policy in 2022. The Southeast Asian country, which just years earlier imposed draconian penalties for cannabis possession (up to 15 years in prison), removed cannabis from the narcotics list in June 2022. Overnight, a largely unregulated market emerged: thousands of cannabis cafés, shops and dispensaries opened across the country, particularly in tourist centres such as Bangkok, Chiang Mai and the islands.

The motivation was primarily economic. The Thai government saw cannabis as an opportunity for agriculture and tourism. Traditionally, cannabis plays a role in Thai cuisine and folk medicine – hemp leaves are used in soups and curries, and traditional healers have used the plant for generations.

The lack of regulation, however, led to problems. Without clear rules for THC limits, age restrictions and quality controls, a Wild West market emerged. High-potency cannabis was sold without age verification, and cannabis tourism took forms that many Thai people considered culturally inappropriate. The government under Prime Minister Srettha Thavisin announced stricter regulation in 2024 to restrict recreational use and limit cannabis primarily to medical use and traditional medicine. As of March 2026, the relevant legislation is still in parliamentary deliberation.

## Malta: Europe's Trailblazer (since 2021)

Malta became the first EU country to legalize recreational cannabis use in December 2021. The Maltese model is more restrictive than the North American approaches and more closely resembles the German KCanG: adults aged 18 and over may possess up to 7 grams of cannabis and grow up to four plants at home. Cannabis associations with up to 500 members can collectively cultivate and distribute cannabis to members.

Commercial sale remains prohibited – there are no dispensaries or cannabis shops. Public consumption is also banned. Malta focuses strongly on decriminalization and harm reduction rather than a commercial market.

Experiences after the first years are mixed. On one hand, hundreds of legacy cases have been dropped and police resources redirected. On the other hand, cannabis associations complain about bureaucratic hurdles in licensing, and the black market persists as legal supply is not yet sufficient.

## Luxembourg: Gradual Reform

Luxembourg announced comprehensive cannabis reform as the second EU country in 2019. Implementation is proceeding step by step: since 2023, home cultivation of up to four plants per household is legal, and possession of up to 3 grams in public spaces is decriminalized (administrative offence rather than criminal offence). A commercial market is planned but not yet implemented.

The Luxembourg model is notable because it treats legalization as a process: first home cultivation is permitted, then experiences are gathered, and only in a second step is a regulated market to be established. This cautious approach reflects the political reality of a small country operating within the EU that must consider its neighbours' reactions.

## Czech Republic: On the Path to Legalization

The Czech Republic has had one of the most liberal drug policies in Europe for decades. As early as 2010, fixed thresholds for personal use were introduced (up to 10 grams of dried cannabis as an administrative offence). Medical cannabis has been legal since 2013. In 2024, the Czech government submitted a detailed bill for full legalization that envisions a regulated commercial market – similar to the Canadian model but with stricter advertising restrictions.

The Czech Republic is deliberately positioning itself as a potential cannabis business hub for Europe. The government argues that early legalization could give the country a competitive advantage in the emerging European cannabis industry. The bill provides for export opportunities for cannabis produced in the Czech Republic to countries with compatible regulatory frameworks.

## South Africa: Constitutional Court Legalization (since 2018)

South Africa legalized cannabis by an unusual route: through a Constitutional Court ruling. In September 2018, the court decided that the prohibition of private cannabis possession and cultivation was unconstitutional because it violated the right to privacy. Adults have since been allowed to grow cannabis at home and consume it privately.

The decision left many questions unanswered: what quantities are legal? May cannabis be sold? What about cannabis clubs? The government was required to create legislation within 24 months but has not yet fully done so. In practice, a grey market has developed: cannabis is sold at informal markets and in so-called Private Cannabis Clubs that invoke the right to privacy.

South Africa's dagga culture (dagga is the local term for cannabis) has deep historical roots. Various indigenous peoples had used cannabis for centuries before the colonial government banned its use in 1928 – one of the world's first cannabis bans, explicitly racially motivated and directed against the Black population. The constitutional court legalization is therefore understood by many South Africans as an act of historical justice.

## Comparing the Models: Lessons and Insights

Several central lessons can be drawn from international experience.

**Black market displacement requires competitive pricing.** Canada's experience shows that the legal market only displaces the black market when prices are competitive. Excessive taxes and regulatory costs – as in California – keep the black market alive. Uruguay has addressed this more effectively through state-mandated pricing below black market levels.

**Commercial market vs. non-profit model.** The North American commercial approach generates high tax revenues and creates jobs but also encourages aggressive marketing and concentration tendencies. The Uruguayan and Maltese non-profit model (cannabis clubs, pharmacies) is more conservative from a health policy perspective but displaces the black market more slowly.

**Youth protection works.** Contrary to many critics' fears, cannabis use among young people has not significantly increased in any country following legalization. In Canada, Uruguay and US states with legalization, data show stable or slightly declining youth consumption rates. Destigmatization appears to reduce the allure of the forbidden, while regulated markets make access harder for minors.

**Regulation is better than non-regulation.** Thailand's experience shows that decriminalization without simultaneous regulation can lead to chaotic conditions. A clear legal framework – even a restrictive one – is preferable to a vacuum.

**Social justice must be actively pursued.** The US experience shows that legalization alone does not remedy the consequences of decades of discriminatory enforcement. Social equity programmes, amnesties for historic cases and targeted economic support for affected communities are necessary but difficult to implement.

## Placing Germany in Context

The German model (KCanG) is most comparable to the Maltese approach: home cultivation and cannabis clubs but no commercial sales. With its cultivation associations, Germany is charting its own course that combines elements of the Uruguayan and Maltese models.

By international comparison, the KCanG is a moderate approach. It is more restrictive than the Canadian or US models but more progressive than the Dutch tolerance policy, which still provides no legal supply chain. The planned regional pilot projects for commercial sales (second pillar of the coalition agreement) could bring the German model closer to North American approaches in the future.

International experience teaches Germany above all one thing: patience. No country has implemented cannabis legalization perfectly on the first attempt. The successful models are those that were willing to learn from mistakes, refine regulation and adapt the legal framework to reality. The KCanG is a first step – not an endpoint.
