The Road to Legalization in Germany

The legalization of cannabis in Germany is one of the most significant drug policy changes in the history of the Federal Republic. It is not a sudden event but the result of a decades-long social, political and legal process. The path from complete prohibition under the Narcotics Act to the Cannabis Consumption Act (KCanG) of 2024 passed through court rulings, cross-party debates, European consultations and ultimately a historic coalition agreement. This article traces the stages of that journey in detail.

## The Starting Point: The Narcotics Act (BtMG)

The Narcotics Act in its current form came into force in 1981, replacing the older Opium Act of 1929. Cannabis was listed in Schedule I of the BtMG – as a non-tradable narcotic whose possession, trade, cultivation and production are fundamentally criminal offences. The penalties were substantial: up to five years' imprisonment for unlawful possession, up to 15 years for commercial trafficking.

In practice, however, a discrepancy between the strict legal text and actual prosecution emerged early on. The public prosecution offices of individual federal states developed so-called threshold quantities below which proceedings for possession of small amounts could be discontinued. These thresholds varied considerably: Berlin's tolerance limit was at times 15 grams, Bremen and Hamburg about 6 grams, while Bavaria could initiate prosecution from as little as one gram. This unequal treatment was criticized for decades as problematic under the rule of law.

## The 1994 Federal Constitutional Court Ruling: A Milestone with Limited Effect

On 9 March 1994, the Federal Constitutional Court issued a landmark decision on the criminality of cannabis possession. In its so-called Cannabis Decision (BVerfGE 90, 145), the court confirmed the fundamental compatibility of the cannabis ban with the Basic Law but simultaneously established that prosecuting authorities may and generally should refrain from prosecution for small quantities intended for personal use.

This ruling was a double-edged sword. On one hand, it acknowledged that criminalizing consumers with small quantities could be disproportionate. On the other, it legitimized the fundamental prohibition and left the definition of "small quantity" to individual federal states – cementing rather than eliminating the existing inequality. A Berlin consumer was treated differently from a Bavarian one for the same behaviour, despite both being subject to the same federal law.

## Failed Reform Attempts of the 2000s

In the 2000s, there were several parliamentary initiatives to reform cannabis policy, all of which failed. The Greens introduced decriminalization bills in the Bundestag in 2002 and again in 2007, which were rejected by the governing majority. Die Linke called for an evidence-based reassessment of cannabis prohibition in various motions. Even within the SPD, there were isolated voices for reform – Hamburg's then Justice Senator Roger Kusch spoke out in favour of controlled distribution in 2002.

At the municipal level, several model project attempts failed. Frankfurt am Main applied for a scientifically accompanied distribution model in 2002, which was rejected by the Federal Ministry of Health. Similar initiatives in Berlin, Cologne and Munich suffered the same fate. The legal obstacle was always the same: the BtMG as federal law left municipalities no room for independent regulation.

At the European level, a 2007 initiative by the Dutch government to establish an EU-wide system of regulated coffeeshops also failed. Resistance came particularly from Sweden, France and Germany. Several German cities – including Frankfurt, Berlin, Cologne and Munich – applied for scientifically accompanied distribution pilot projects that were rejected by the federal government, as the BtMG left no room for municipal experimentation.

These failed attempts were nevertheless not in vain. They helped keep the public debate alive, develop legal lines of argument and shape a generation of politicians, lawyers and activists who would bring about the actual legalization 20 years later.

## The Debate of the 2010s

In the 2010s, the social debate around cannabis intensified considerably. Several factors drove this development:

**Growing scientific evidence:** Research on cannabis and the endocannabinoid system produced increasingly nuanced findings. The image of cannabis as a uniform gateway drug was largely rejected by science. At the same time, the risks were not denied but placed in an evidence-based context.

**International models:** Legalization in Colorado (2012), Uruguay (2013) and Canada (2018) demonstrated that regulated cannabis markets could function without the feared horror scenarios materializing. The Canadian model in particular was intensively discussed in Germany.

**Failed prohibition:** The number of cannabis consumers in Germany rose continuously despite the ban. An estimated four million Germans consumed cannabis regularly, the black market flourished, and quality control was non-existent. Synthetic cannabinoids reaching the black market as cheap adulterants posed significant health risks.

**Petitions and citizens' initiatives:** Several Bundestag petitions for legalization achieved high supporter numbers. The German Hemp Association's 2017 petition recorded over 79,000 signatures and was deliberated in the Petitions Committee.

**Federal Drug Commissioners:** The successive Federal Drug Commissioners played an ambivalent role. While some defended cannabis prohibition, the CSU's Marlene Mortler (2014–2019) inadvertently opened the door to criticism of prohibition's intellectual foundations with her widely quoted statement that cannabis was forbidden because it is illegal. Burkhard Blienert (SPD), the first Drug Commissioner of the Ampel coalition, actively accompanied the legalization process and advocated for an addiction policy based on prevention rather than repression.

**Party-political positioning:** The Greens had demanded legalization since the 1990s. The FDP joined with a market-oriented approach in the 2010s. The SPD underwent a gradual shift from rejection to openness. The CDU/CSU and AfD maintained their prohibitionist stance.

## Medical Cannabis: The 2017 Law

An important intermediate step was the Act Amending Narcotics Law and Other Provisions of 6 March 2017, which gave seriously ill patients access to medical cannabis on health insurance prescription. Previously, only a few hundred patients could obtain cannabis through a special permit from the Federal Institute for Drugs and Medical Devices (BfArM).

The law was unanimously adopted by the Bundestag – a rare cross-party consensus. It marked a paradigm shift: for the first time, the legislature officially acknowledged that cannabis can have therapeutic value. The practical implementation proved bumpy, however. Many doctors shied away from prescribing due to uncertainty or reservations, health insurance reimbursement was frequently denied, and available quantities were initially insufficient.

## The 2021 Coalition Agreement: The Historic Promise

The federal election of 26 September 2021 led to the formation of the Ampel coalition of SPD, Greens and FDP. The coalition agreement of 24 November 2021, titled "Daring More Progress," stated on page 68:

"We will introduce the controlled distribution of cannabis to adults for recreational purposes in licensed shops. This will ensure quality control, prevent the distribution of contaminated substances, and guarantee youth protection."

This sentence was historic: for the first time, three governing parties had formulated cannabis legalization as a shared objective. Federal Health Minister Karl Lauterbach (SPD), who had transformed from a former legalization opponent to a supporter, took the lead.

## European Hurdles and the Two-Pillar Approach

Implementing the coalition promise proved more complicated than expected. A first draft bill envisaging a full commercial market with licensed retail outlets failed due to European legal concerns. The European Commission signalled that such a model might conflict with EU law – particularly the Schengen acquis and the EU Framework Decision on combating drug trafficking.

Health Minister Lauterbach then presented a modified approach in April 2023: the two-pillar model. The first pillar covered private possession, home cultivation and non-commercial cultivation associations (Cannabis Social Clubs). The second pillar envisaged regional pilot projects with commercial retail outlets, to be scientifically monitored.

This compromise was contested within the Ampel coalition. The FDP would have preferred a full commercial market, the Greens criticized the restrictions as too severe, and parts of the SPD still had reservations. Nevertheless, the coalition agreed on the draft bill, which was first introduced in the Bundestag in August 2023.

## The Parliamentary Process

The draft bill passed through several phases:

**First reading (October 2023):** The draft was presented in plenary and referred to the Health Committee. The opposition – CDU/CSU, AfD and parts of Die Linke – rejected the bill but could not block it.

**Expert hearing (November 2023):** The Health Committee heard experts from medicine, law, addiction research and policing. The experts expressed mixed views: addiction medicine specialists emphasized the opportunities of decriminalization, police representatives warned of enforcement problems, and lawyers debated European legal compatibility.

**Committee amendments:** The bill was revised on several points. Possession limits were clarified, youth protection provisions tightened, and transitional provisions for existing criminal proceedings specified.

**Second and third readings (February 2024):** On 23 February 2024, the law was adopted by the Bundestag in a roll-call vote with 407 to 226 votes and 4 abstentions. The coalition groups voted unanimously in favour, the opposition unanimously against.

**Bundesrat (March 2024):** Since the KCanG was classified as an objection law rather than a consent law, the Bundesrat could not block it. An objection, demanded by several CDU/CSU-led state governments, failed to materialize as the necessary absolute majority was lacking.

**Promulgation and entry into force:** The law was published in the Federal Law Gazette on 27 March 2024 and came into force on 1 April 2024.

## The KCanG: Core Provisions

The Cannabis Consumption Act established the following legal foundations:

**Private possession:** Up to 25 grams in public spaces, up to 50 grams in private areas. Home cultivation of up to three flowering plants per person.

**Cultivation associations:** Non-commercial associations (Cannabis Social Clubs) with a maximum of 500 members may collectively cultivate and distribute cannabis to their members. Distribution is limited to 25 grams per day and 50 grams per month; for those aged 18–21, 30 grams per month with a maximum THC content of 10 percent.

**Youth protection:** Consumption banned in 100-metre exclusion zones around schools, childcare facilities, playgrounds and sports venues, and in the presence of minors. Distribution exclusively to persons aged 18 and over.

**Amnesty:** Existing convictions under the BtMG that would no longer be criminal under the new law are to be reviewed ex officio and, where applicable, overturned.

## CSC Regulations in Detail

Cannabis Social Clubs (CSCs) are the centrepiece of the KCanG and its most innovative element. Unlike the Netherlands or Canada, there is no commercial retail – instead, Germany relies on the model of collective, non-profit production.

**Founding:** A CSC must be established as a registered association (e.V.). Founding members must be of legal age and must not have been convicted of drug offences in the preceding five years. The association requires an operating licence from the competent state authority.

**Cultivation facilities:** Growing areas must be secured and inaccessible to unauthorized persons. Surveillance technology, burglar-resistant doors and windows, and clear access documentation are mandatory.

**Quality control:** Cultivated cannabis must be tested for THC and CBD content as well as contaminants (pesticides, heavy metals, mould). Packaging must display THC content, harvest date and health risk information.

**Addiction prevention:** Every CSC must designate a qualified addiction prevention officer who advises members, identifies risky consumption patterns and refers to professional support services when needed.

## Implementation in Practice

Practical implementation of the KCanG was not smooth. Several challenges emerged in the first months after entry into force:

**Administrative delays:** Many federal states were unprepared for the new responsibility. The competent authorities had to be identified, staff trained and administrative processes established. In some states – particularly Bavaria and Saxony – approval procedures for CSCs were deliberately delayed or burdened with high bureaucratic hurdles.

**Seeds and cuttings:** The legal procurement of seeds and cuttings proved to be a practical problem, as commercial trade was not provided for. CSCs were only permitted to obtain seeds from other CSCs or from within the EU, which delayed the start-up phase for many associations.

**Police transition:** Police authorities had to adapt their practices – from prosecuting every cannabis possession to verifying whether legal limits were being observed. This required training and clear service instructions, which in many federal states were only available with a delay.

**Amnesty implementation:** Reviewing existing convictions placed a considerable workload on the judiciary. Hundreds of thousands of files had to be examined to determine whether the underlying actions would still be criminal under the new law. Many courts reported significant backlogs, and the amnesty process took longer than expected.

**Public consumption:** The first weeks after entry into force saw widespread public cannabis consumption, particularly at the large "Smoke-In" gatherings that took place in Berlin, Hamburg and other cities on 1 April 2024. While legal under the KCanG (subject to the exclusion zone rules), this visibility provoked criticism from prohibition supporters and renewed calls for stricter enforcement.

## Political Reactions and the Change of Government

The KCanG remained politically controversial. CDU/CSU and AfD announced their intention to repeal the law upon assuming government. The Bavarian state government under Markus Söder (CSU) issued particularly restrictive implementing regulations.

Following the collapse of the Ampel coalition in November 2024 and the early elections, the future of the KCanG hung in the balance. The new federal government has so far not taken concrete steps toward repeal, partly because a complete reversal would be legally complex and politically costly. The licences already issued, ongoing amnesty proceedings and the changed social consensus make a simple return to the status quo ante unlikely.

## Social Change

Regardless of the party-political debate, surveys show a clear societal trend. According to a 2024 infratest-dimap survey, approximately 65 percent of the German population supports the decriminalization of cannabis possession, and about 50 percent support controlled legalization with commercial sales. Approval is particularly high among younger age groups (18–39) at over 70 percent.

This societal change is reflected in everyday reality. Open consumption in major cities increased markedly after 1 April 2024, Cannabis Social Clubs have become an established part of associational life, and media coverage has shifted from sensationalist to normalized in tone. In cities like Berlin, Hamburg and Cologne, cannabis-related events, fairs and cultural formats have become established, addressing broad audiences and presenting cannabis as a normal part of social life.

The workplace is also showing changes. While some employers have relaxed their drug policies, others maintain strict controls. The employment law dimension of cannabis use – particularly the question of whether an employer may require a drug test that captures legal recreational use – is the subject of ongoing legal debate and will likely only be conclusively resolved through case law from the highest courts.

## International Comparison: Germany's Distinctive Path

Germany's approach differs markedly from the models of other countries. While Canada and Uruguay have built fully commercial markets with government-licensed retail outlets, Germany relies on the model of non-commercial cultivation associations. This approach has no direct precedent in another country and represents an experiment.

The Dutch gedoogbeleid with its coffeeshops comes closest to the German model but differs in essential respects: in the Netherlands, retail sales are tolerated but production is illegal – the so-called back-door problem. In Germany, conversely, production in CSCs is legal but commercial sales are prohibited. The German model thus avoids the back-door problem but creates an access barrier, as consumers must join an association to obtain legally sourced cannabis.

Spain pursues a similar model with its Cannabis Social Clubs, which have existed in a legal grey area since the 2000s. However, the Spanish CSCs are not legally regulated but operate in a space between tolerance and occasional prosecution. The German KCanG has the advantage of legal certainty for both the associations and their members.

Experience from Canada and US states shows that commercial markets displace the black market considerably more effectively than non-commercial models. In Canada, the share of the illegal market fell from an estimated 90 percent to under 40 percent within five years of legalization. Whether the German model without a commercial market can achieve comparable black market displacement is one of the central open questions.

## The Role of Civil Society

Legalization in Germany would not have come about without years of civil society engagement. The German Hemp Association (Deutscher Hanfverband, DHV), founded in 2002, was the driving force of the legalization movement for two decades. Through petitions, media presence, legal support for affected individuals and systematic policy advice, the DHV contributed significantly to placing the issue on the political agenda.

The annual Hanfparade in Berlin, held since 1997, grew from a small rally to a demonstration with tens of thousands of participants. It functioned as a barometer of social change and a platform for political demands. After the entry into force of the KCanG, the character of the Hanfparade has shifted – from protest action to celebration of the achieved partial legalization, combined with demands for further reforms.

Academic voices also contributed to the discourse. The 2013 petition by over 120 criminal law professors calling for decriminalization had considerable media resonance and undermined the argument that legalization was demanded only by consumers. Similarly influential was the resolution of the 128th German Medical Assembly in 2024, which supported evidence-based cannabis policy.

## Conclusion and Outlook

The road to cannabis legalization in Germany was long, contested and marked by compromises. The KCanG is neither the full legalization that supporters had hoped for nor the catastrophe that opponents prophesied. It is a pragmatic middle path that decriminalizes and regulates private cannabis use without creating a commercial market. The legally mandated evaluation by 2028 will determine whether Germany expands, maintains or restricts this model. What is already clear: after decades of prohibition, Germany has changed course, with societal effects reaching far beyond the question of cannabis consumption itself.
