Two Years of Legal Cannabis from Specialized Retail Stores: Swiss Pilot Project Shows Positive Effects on Health Protection, Consumer Competence, and Combating the Illicit Market

One of the most compelling results after two years concerns the potential displacement of the illicit market. Among the more than 1,600 current study participants, parallel sourcing of cannabis from other channels has declined significantly. Whereas before entering the study cannabis was obtained from the illicit market on an average of about 20 days per month, this figure has roughly halved over the course of participation. At the same time, many participants now rely exclusively or predominantly on the legally supplied study products from the specialty stores – sometimes even involving longer travel times, despite other sources being easier for many to access. “This development is highly relevant from the perspective of health and consumer protection,” says Prof. Dr. Michael Schaub, Scientific Director at ISGF and head of the study. “It suggests that consumers are willing to leave the illicit market when they have access to quality-tested products from controlled sources and to reliable information.”

Professional Counseling as a Reliable Source of Information
Professional counseling in the specialty stores is also becoming increasingly important for participants. The trained sales staff – so-called “budtenders” – are viewed as a useful source of information on lower-risk cannabis use by a majority of participants. Many subjects report having adjusted their consumption behavior following counseling sessions, for example with regard to dosage, THC content, product choice, or method of consumption. “We see a clear link here between a regulated setting, counseling, and responsible consumption,” Schaub adds. “This central element is, of course, completely absent from the illegal market.” 

Safer Use: Harm-Reducing Accessories and Lower-Risk Consumption Methods
Changes in consumption behavior can also be observed in terms of harm reduction. Particularly striking is the increase in the use of activated charcoal filters, which can reduce health risks of smoking more effectively than conventional cigarette filters, paper, or cardboard. The growing spread of such “safer use” practices indicates that consumers in a legal framework are more receptive to health education and risk-reduction measures. Positive trends can also be observed with regard to consumption methods: over time, study participants are increasingly engaging with less harmful options such as edibles, drops, or vaporizers.

“Germany Is Taking the Opposite Path”
For Finn Hänsel, founder and CEO of Sanity Group, the results send a clear message to policymakers in both Switzerland and Germany: “While in Switzerland we can now see that regulated specialty stores can help strengthen health protection and effectively curb the illicit market, pilot projects in Germany – such as those proposed in Frankfurt am Main, Hanover, or Berlin – have recently been rejected. Germany is taking the opposite path and, in our view, the wrong one. Anyone who truly wants to achieve legalization goals such as comprehensive health protection and sustainable suppression of the illicit market must be willing to test them scientifically, rather than foregoing evidence for ideological reasons.”

Switzerland, by contrast, continues to consistently prioritize evidence generation. “Switzerland understands that sensible regulation has to be adaptive,” says Leonhard Friedrich, Managing Director of Sanity Group Switzerland. “Pilot projects like this provide the data basis for a realistic, responsible cannabis policy. After two years, we can draw an entirely positive interim assessment and remain in close dialogue with the authorities. It is encouraging that the evidence being generated here can make a meaningful contribution to legislation.”

In Germany, comparable evidence is still nowhere in sight, according to Finn Hänsel: “Without corresponding model projects, such important data and insights will continue to be lacking.”

Research application initially rejected: Scientific pilot project on recreational cannabis in Frankfurt and Hanover denied regulatory approval

The project partners – comprising the scientific leads Prof. Dr. med. Kirsten Müller-Vahl (Medizinische Hochschule Hannover) and Prof. Dr. Heino Stöver (formerly Frankfurt University of Applied Sciences), as well as Sanity Group – disagree with the authority’s legal assessment: “We subjected the legal foundations of the research application to particularly thorough legal scrutiny and additionally secured them with an external legal report. It concluded that the research clause of Pillar 1 of the KCanG indeed provides a legal basis for scientifically designed pilot projects on recreational cannabis,” said Finn Hänsel, founder and CEO of Sanity Group. The report was made available to the authority during the review process.

Telemedicine debate makes legal alternatives more urgent
Sanity Group also views the BLE’s decision critically in light of current health policy developments. Ongoing discussions about stricter regulation of specialized telemedicine platforms in the medical cannabis sector threaten to cut off legal access for many people through the medical market. “We of course consider it the right step to make telemedical services available only to patients with serious health conditions. But if this area is more strictly regulated, there is an urgent need for legal alternatives. Otherwise, consumers who have so far at least obtained quality-assured products through the medical system instead of through illegal channels will be forced back into the illicit market – and thus back to unpredictable health risks,” Hänsel continued.

Such an outcome would run counter to the objectives of the Cannabis Act, which explicitly aims to strengthen health and youth protection while curbing the illicit market. “Pilot projects like those in Hanover and Frankfurt offer the chance to test scientifically sound and sensible solutions precisely for this need. This would create a clear separation between recreational use and medical therapy, provide a comprehensive data basis, and significantly relieve the medical care system.”

Looking to Switzerland underscores potential
The planned pilot projects were intended to scientifically study and evaluate, for the first time in Germany, the legal distribution of recreational cannabis in licensed specialty stores. The goal was to generate data for evidence-based regulation, similar to Switzerland, where comparable pilot projects have been providing valuable insights into consumption behavior, prevention, and illicit-market reduction since 2023.

“Home cultivation and cannabis clubs alone cannot meet demand in Germany; they are simply insufficient as legal sources of supply. Together with our partners, we will therefore continue to advocate that cannabis consumers are not once again left to the illegal market,” Hänsel emphasized. “And international experience proves us right: scientifically monitored pilot projects are the right path to combine health protection and consumer safety with effective illicit-market reduction.”

Health protection and illicit-market reduction: central research questions
In the study planned for Hanover and Frankfurt, registered adult participants were to be granted legal access to cannabis flowers and other THC-containing products at real market prices over a five-year period. The aim of the project was to investigate the effects of regulated cannabis distribution for recreational purposes – for example, on consumer health, youth protection, the illegal market, and organized crime. The project’s results could enable an evidence-based evaluation and provide a foundation for further decisions regarding cannabis legalization legislation.

EKOCAN evaluation results: pioneering insights
On Monday, initial interim results of the accompanying evaluation of KCanG were presented at a federal press conference, carried out by the joint research project “EKOCAN.” A key finding of the report: As of April 2025, production by cannabis cultivation associations covered less than 0.1 percent of total demand in Germany. Another reason, Hänsel argued, to make scientifically monitored pilot projects for specialized retail outlets possible. He views the publication of these interim results as an important opportunity to reinforce the case for pilot projects: “The findings strengthen our call for supplementary, scientifically monitored distribution models. It remains to be seen whether the results will also serve as a basis for adjustments to the KCanG or for the potential approval of pilot projects.”

Coalition Agreement Presented: Sanity Group Welcomes Planned Evaluation of Cannabis Law and Calls for Scientific Pilot Projects

“It is the right step that the coalition intends to evaluate the Cannabis Act as planned, to assess how the partial legalization has impacted issues such as youth protection, public health, and fighting the illicit market,” says Finn Age Haensel, founder and CEO of Sanity Group. “At the same time, it is crucial to fully implement the law first. That is why we call for the prompt approval of scientific pilot projects for the distribution of recreational cannabis through licensed specialty stores. These will allow us to gain new insights based on solid data and practical experience. Only through a data-driven and scientifically grounded analysis can we implement the right measures to establish a quality-assured and responsible cannabis market while minimizing health risks to the population.” 

Ensuring Medical Care: Cannabis Patients in Focus 
In the field of medical cannabis, Sanity Group calls for continuous improvements in supply security. “The needs of patients must continue to be front and center. We advocate for widespread, low-threshold access to medical cannabis therapy that consistently upholds the highest standards of quality and safety,” explains Haensel. “Medical treatment with cannabis-based medicines should be made as accessible and straightforward as possible for all who need it.” 

With the evaluation of the Cannabis Act, the new government is sending a clear signal for an evidence-based approach to recreational cannabis. Sanity Group is convinced that the introduction of scientific pilot projects will promote the responsible distribution of cannabis and pave the way for a modern drug policy.

Cannabis Dispensaries in the German Capital: Sanity Group Plans Scientific Pilot Projects with Two Berlin Districts

At today’s press event, held at Pablo Neruda Central Library in Berlin, Clara Herrmann (Bündnis 90/Die Grünen), District Mayor of Friedrichshain-Kreuzberg, and Hannes Rehfeldt, CDU District Councilor for Social Affairs and Health in Neukölln, signed a letter of intent to carry out the pilot project. The scientific lead of the cannabis pilot study will include Professor Dr. Dr. Christian Ulrichs, Head of Urban Plant Ecophysiology at Humboldt-Universität zu Berlin. The dispensary concept for the project was developed by Sanity Group.

“The fact that Berlin districts have now also expressed their intention to implement cannabis pilot projects is, of course, something very special for us as a Berlin-based company,” said Finn Hänsel, founder and CEO of Sanity Group. “We are proud to contribute our expertise and experience in the design and operational implementation of this pilot project and to pioneer this effort directly in our city.” Protecting the health of consumers is one of the central objectives of Germany’s partial cannabis legalization, Hänsel added, emphasizing the need to shrink the illegal market as a priority. “Personal cultivation and cannabis clubs alone are not enough to provide consumers with access to safe, regulated cannabis and to sustainably combat the black market. This makes it all the more important to use scientific studies to set the course for achieving legalization goals. The fact that CDU, alongside the Green Party, is now driving such a project forward in Neukölln adds significant momentum.”

Five Years of Scientific Observation: Promoting Responsible Consumption as a Key Pillar
The pilot project will grant adult study participants legal access to cannabis products at dispensaries in the two districts. Participation requires meeting certain health criteria and engaging in regular scientific surveys as part of the study. Passing purchased products to third parties will result in immediate exclusion. To ensure that only study participants can shop at the dispensaries, they will receive a pseudonymized participant ID. This ID, read digitally by dispensary staff, will track which products and quantities have already been purchased at specific locations. A QR code on product packaging ensures that the legally permissible quantity is not exceeded.

To provide low-threshold intervention options, dispensary staff will be available to answer questions and address any signs of problematic consumption behavior. This allows for referrals to associated counseling services before potentially harmful addiction patterns may emerge. The dispensaries will use software from the Swiss company Cannavigia to document sales quantities and the entire supply chain, enabling individual analysis of consumption patterns. Additionally, regular workshops and informational events on responsible and reflective cannabis use will be a core component of the study.

Analysis Shows High Contamination in Berlin’s Illegal Cannabis
The urgency of curbing the illegal cannabis market to protect consumer health was highlighted by a recent laboratory analysis of black-market cannabis from 30 German cities, including Berlin. Samples revealed that over two-thirds of the tested cannabis contained traces of toxic pesticides, while around one-third was laced with substances like hairspray. Traces of other drugs, including cocaine and MDMA, were also detected. These findings underscore the critical need for clean cannabis from commercial supply chains, such as those enabled by pilot projects. The study will now evaluate whether licensed cannabis dispensaries can be a viable path toward this goal.

KCanWV: Regulation on Research Projects in Model Regions Officially Announced
Independent of the planned second pillar of the Cannabis Consumption Act (KCanG), under which model regions with specialized stores were to become reality, a draft regulation from the Federal Ministry of Food and Agriculture (BMEL) has been available since April 2024. This regulation designates the Federal Agency for Agriculture and Food (BLE) as the competent authority for research projects aimed at non-medical purposes. With the announcement by the ministry on Wednesday that the so-called “Cannabis Consumption Science Competency Regulation” (KCanWV) will come into effect, applications for relevant projects can be submitted to the BLE by research institutions and companies, starting from its publication in the Bundesgesetzblatt.
