The swizz pilot project Cann-L in Lausanne shows clear results after two years of operation. Over 1,750 participants have joined the state-approved trial, which aims to study the effects of regulated cannabis sales for adults. The results point to reduced consumption and significantly weakened revenues for the illegal market.
20% Lower Consumption
A scientific analysis of the first participant group shows that consumption decreased by an average of around 20% after 18 months in the program. This contradicts concerns that legal access would automatically increase use.
The project now accounts for approximately 20% of the estimated total cannabis consumption in Lausanne. At the same time, the black market is estimated to have lost at least two million Swiss francs in revenue due to participants purchasing through the legal model instead.

Health-Focused Approach
Cann-L is based on a non-profit model where participants gain access to controlled products with clearly defined THC and CBD levels. Sales are combined with counseling and information on risk reduction.
Around 100 participants have, through the project, come into contact with healthcare or counseling services, in several cases for the first time. The low threshold for support is seen as an important part of the project’s public health strategy.
A Test for Future Regulation
Switzerland has launched several scientific pilot projects to evaluate how a regulated cannabis market could function. The findings from Lausanne provide concrete data for the national debate on future legislation.
The preliminary results show that a controlled model can reduce consumption, weaken the illegal market, and strengthen contact between users and healthcare services.
The development in Lausanne is now being closely monitored by both researchers and policymakers, as the project may influence how future regulation is designed in Switzerland.
