A New Approach to Cannabis Policy
Across Europe, governments are increasingly looking for evidence-based alternatives to cannabis prohibition. One of the most promising initiatives is taking place in Zurich, Switzerland, where the Züri Can pilot program is exploring how a strictly regulated cannabis market can improve public health, reduce illegal trade, and provide valuable scientific data for future legislation.
Rather than simply allowing legal cannabis sales, the project has been designed to answer an important question: can responsible regulation create a safer and more transparent cannabis market than prohibition?
Encouraging Results After Two Years
The answer appears to be increasingly positive. Following the success of the pilot, Zurich authorities have requested a two-year extension, pointing to encouraging results in reducing purchases from the illicit market and increasing participation in regulated sales channels.
Since the program launched in 2023, more than 2,300 adults have joined the study. Together, participants have completed around 88,000 legal cannabis purchases, representing approximately 750 kilograms of regulated cannabis products.
Researchers estimate that these legal sales have diverted roughly CHF 7.5 million (around €8 million) away from the black market. This suggests that when consumers have access to safe, legal, and quality-controlled cannabis, many are willing to leave illegal suppliers behind.
Scientific Research at the Heart of the Project
What makes Züri Can unique is its strong scientific foundation. The pilot is accompanied by a long-term study involving more than 2,100 regular cannabis consumers, who are being monitored over a three-year period.
The research compares different legal access models, including licensed pharmacies, non-profit cannabis social clubs, and a municipal drug information centre. By evaluating these distribution systems, researchers hope to identify which model best promotes responsible cannabis use while minimizing potential risks.
The findings will help policymakers make future decisions based on real-world evidence instead of assumptions or political ideology.
Public Health Comes First
Unlike commercial cannabis markets that focus primarily on sales, the Zurich pilot places public health at the centre of its strategy.
Participants receive products that meet strict quality standards, while regulations allow authorities to set THC limits, prohibit advertising, and provide clear information about responsible consumption and potential health risks.
These measures are designed to reduce harm, improve consumer safety, and encourage informed decision-making. The project demonstrates that cannabis regulation can go far beyond legalization by creating a controlled environment where health protection is a priority.
Switzerland May Lead the Way
The success of the pilot comes at an important moment for Switzerland. The federal government is currently preparing the Cannabis Products Act (CanPG), legislation that could establish a fully regulated adult-use cannabis market across the country.
If approved, Switzerland could become the first European nation to introduce nationwide cannabis legalization based on scientific evidence gathered through large-scale pilot projects.
This evidence-driven approach is attracting attention from policymakers throughout Europe, many of whom are closely monitoring the Swiss experience.
A Model for the Future?
The Zurich pilot reinforces an important message: cannabis legalization is about much more than creating a legal market. It is about replacing an unregulated system with one that prioritizes product quality, consumer safety, education, and public health while reducing the influence of the illegal market.
As additional research becomes available over the coming years, Züri Can could become one of Europe’s most influential case studies on responsible cannabis regulation. For countries considering cannabis reform, Switzerland may well provide the blueprint for a safer and more effective approach to adult cannabis use.
