Paper: Growing pains: A study of administrative burden and regulatory compliance in German Cannabis Cultivation Associations under the Cannabis Act

The regulation of cannabis remains a contested policy issue, marked by tensions between public health, criminal justice, and individual autonomy. Central to this debate is the question of how cannabis should be governed in ways that minimise harms while safeguarding rights and social welfare.

Prohibition and reliance on the black market expose cannabis users to a range of harms, including adulterants added to cannabis (such as lead or glass to increase weight), contamination with mould or bacteria, criminalisation and its long–term consequences (criminal records, restricted job and housing opportunities), over–policing and disproportionate enforcement, and the risks of unsafe purchase environments (Belackova et al., 2016; Kilmer, 2014). Legal cannabis markets, similarly, introduce risks: increased consumption, profit–driven commercial interests with strong incentives to retain heavy users, normalisation of cannabis use, reduced prices through industrial cultivation, aggressive marketing, and the development of innovative high–potency or youth–targeted products (Kilmer, 2014; Lancione et al., 2020; Manthey et al., 2024). In response to these competing risks, middle–ground models of collective, non–commercial cannabis cultivation has emerged, most prominently Cannabis Social Clubs (CSCs) (Belackova et al., 2023).

The German Konsumcannabisgesetz (the Cannabis Act, henceforth referred to as ‘the Act’), enacted in April 2024, is significant both because of Germany’s role as a major European political power and because it represents the first European attempt to formalise CSC practices through Cannabis Cultivation Associations (CCAs). The Act and its CCA model embody a broader political tension: on the one hand, a desire to establish a legal pathway for non–medical cannabis access, and on the other, a need for regulatory control to minimise societal harms.

The Act legalised personal possession of up to 25 g cannabis and up to three plants for home cultivation by adults. As of July 2024, the law also permits collective, non–commercial cannabis production through CCAs. While medical cannabis via prescription has been legal in Germany since 2017, the reform has enabled two new legal avenues for adult cannabis access: personal home cultivation and participation in a CCA.

The stated aims of the Act are to improve the health of cannabis consumers, reduce the size of the illicit market, and enhance youth protection (Fischer & Hall, 2023; Manthey et al., 2024; Bundesgesundheitsministerium, 2025, FAQ on the Act). To support these aims, the law mandates that CCAs implement a range of harm reduction measures. These include distributing educational materials on the risks of cannabis use, appointing and training two addiction prevention officers at each CCA to monitor and advise members on their cannabis use, and conducting regular laboratory testing to verify the THC and CBD content of cannabis products. The minimum age for joining a CCA is 18 years, but individuals aged 18 to 21 are only permitted to access cannabis with a maximum THC content of 10 % (Bundesgesundheitsministerium, 2025, FAQ on the Cannabis Act). These requirements aim to distinguish CCAs from the illicit market by embedding public health safeguards into the legal supply model. However, while THC testing is mandated, broader safety requirements remain vague and are often inferred from standards governing medical cannabis or food products (Fischer & Hall, 2023; Manthey et al., 2024).

Seven founding board members are needed to establish a CCA, including a first chairperson, second chairperson, and a treasurer. Although CCAs are considered non–commercial entities, the law permits limited employment within the association. Members may be hired for tasks directly related to cultivation, while non–members may be employed in ancillary roles such as bookkeeping or facility maintenance (Bundesgesundheitsministerium, 2025). Other regulatory constraints on CCAs include a maximum of 500 members per association and a 200–metre buffer zone from schools or youth facilities. Moreover, all members must “actively participate” in the cultivation process, defined as direct involvement in growing or related activities, reinforcing the model’s supposed cooperative logic (Konsumcannabisgesetz (The Act) 2024).

As of march 2025, 500 CCAs had applied for a cultivation license, with only 190 receiving permits (Stevens, 2025). In a survey from August 2025 of 11,471 cannabis users, only 1.9-2.5% reported obtaining cannabis primarily through a CCA, whereas most relied on home cultivation (49%) or pharmacies (29.2%) (Steimle et al., 2025).

CSCs are non–commercial associations that collectively cultivate cannabis for the personal use of registered members and typically involves member–based governance, decentralised decision–making, and cultivation volumes based on anticipated consumption needs, as documented in countries such as Spain, Belgium, and Uruguay (Decorte, 2015; Boidi et al., 2016; Decorte et al., 2022; Pardal et al., 2022; Belackova & Wilkins, 2018). Research has suggested that CSCs can be vehicles for harm reduction and social justice for drug users (Belackova et al., 2023; Obradors–Pineda et al., 2021; Pardal et al., 2020).

Uruguayan CSCs operate under a fully legal framework, unlike the tolerated or informal CSCs in Spain and Belgium. However, they still face challenges, such as: collective action problems, stigma and local opposition, a low membership cap of 45 individuals, which increases the per–person cost of collective cultivation, and the requirement of at least 15 founding members to establish the CSC (Queirolo et al., 2016).

Unlike traditional CSCs, German CCAs are not permitted to facilitate on–site cannabis use, undermining the social, communal aspects central to the CSC concept. Many CCAs nevertheless refer to themselves as CSCs or incorporate the CSC label in their association names. However, this distinction necessitates the use of the term Cannabis Cultivation Association when discussing the German context – legally, they are also referred to as an Anbauvereinigung, which directly translates to “cultivation association.”

This study draws on Administrative Burden Theory (ABT) and Regulatory Compliance Theory (RCT) to understand the challenges of establishing and operating CCAs under the Act. ABT was selected alongside RCT to capture both the practical burdens of interacting with complex regulatory requirements and the motivational and legitimacy–related aspects of compliance. Alternative frameworks, such as participatory governance, were considered but deemed less suitable. Participatory, or collaborative, governance is typically defined as consensus–oriented and involving non–state stakeholders in the policy process, not just its implementation (Ansell & Gash, 2008; Fung & Wright, 2001).

ABT is applied to the individual CCA organiser navigating state regulations, experiencing the burdens of citizen–state interactions firsthand. ABT identifies the costs individuals face when dealing with government regulations (Moynihan et al., 2015). For CCA organisers, these include:

• •
  Learning costs: the time and effort required to interpret legal obligations;
• •
  Compliance costs: fulfilling documentation, registration, and reporting requirements; and
• •
  Psychological costs: stress, uncertainty, and concerns about enforcement or public perception.

The high upfront financial, administrative, and legal requirements of setting up a CCA resemble the “start–up costs” faced by new businesses, acting as threshold barriers that favour organisers with access to expertise, capital, and personal time (Chambers & Munemo, 2019; Hopp & Sonderegger, 2015; Hopp & Stephan, 2012). CCAs share features with “social” start–ups, which prioritise social or public health objectives over commercial growth (Mair & Marti, 2004; Ratten, 2023). While most start–up definitions emphasise rapid growth and scalability – which do not apply to CCAs – parallels remain in terms of risk exposure, resource requirements, and the entrepreneurial effort needed to navigate complex regulatory environments (Ratten, 2023; Zahra et al., 2006). This article refers to the challenges inherent to start–ups as ‘start–up barriers’ and recognises that CCAs also face these, compounded by the unique stigma associated with the cannabis sector.

RCT complements ABT by focusing on the motivations for compliance and perceptions of authority legitimacy (Sutinen & Viswanathan, 1999). RCT distinguishes between intrinsic motivations, such as belief in the purpose of the law, and extrinsic motivations, such as concern for social reputation, potential sanctions, or financial consequences, that drive adherence to rules. Authority legitimacy is evaluated across four dimensions: effectiveness of outcomes, distributive justice of outcomes, efficiency of processes, and procedural justice (Sutinen & Viswanathan, 1999). This framework is particularly useful for understanding compliance behaviour in contexts where regulations may be perceived as burdensome or only partially legitimate, highlighting how both intrinsic commitment and extrinsic pressures shape adherence to rules. Together, ABT and RCT, along with the start–up context, provide a complementary lens to interpret the data, linking practical burdens, motivational drivers, and regulatory interactions to the real–world challenges faced by CCA organisers.

Throughout the article, we use ‘challenges’ as an overarching term. Where theoretically relevant, we specify whether these challenges are best understood through ABT, RCT, or as start–up barriers.

  What are the main challenges in establishing and operating a Cannabis Cultivation Association under the Cannabis Act?

This question connects the theoretical insights from ABT, RCT and start–up literature, to the real–world dynamics of regulated cannabis cultivation, highlighting how legal requirements, administrative burdens, and individual motivations shape participation and thus the broader realisation of the Act’s aims.
