In Switzerland, several pilot projects on the regulated sale and consumption of cannabis have been underway for some time with the aim of collecting data for a possible new legal regulation. These projects allow study participants to legally purchase and consume cannabis for recreational purposes in a controlled setting.
For example, the largest cannabis trial in Switzerland to date was launched in Zurich in May 2024. Here, around 7,500 test subjects can buy cannabis products in special sales outlets and pharmacies. They are scientifically supervised in order to record consumption and its effects. At the same time, there is a control group of 2,500 people who do not have access to legal cannabis in order to better understand differences in consumer behavior.
Basel is also running a similar project called “Grashaus Projects”, which monitors the legal sale of cannabis containing THC. The research focuses on the effects of regulated consumption and its possible health and social consequences. In addition to direct consumption data, the effects on youth protection, prevention and education are also being investigated
The SCRIPT study (Safer Cannabis – Research In Pharmacies) is investigating the legal sale of cannabis in pharmacies in Switzerland. Following the successful launch in Bern, the project was also extended to Biel and Lucerne. Participants are randomized to buy cannabis products in pharmacies either immediately or after a six-month waiting period. The aim of the study is to collect data on the safe and controlled use of cannabis , which should form a basis for future legal regulations. The study management is working closely with the cities and pharmacies to monitor and evaluate the pilot trial. The aim is to gain insights into preferred places of consumption, purchasing behavior and consumption motives.
You can find more information about the study on the official SCRIPT studywebsite.

Herba di Berna’s perspective on pilot projects and cannabis regulation
As a company committed to the healthy and responsible use of cannabis, we at Herba di Berna welcome the ongoing pilot projects in Switzerland. These studies, such as the SCRIPT study in Bern, Biel and Lucerne and the large-scale projects in Zurich and Basel, provide valuable insights into the effects of regulated cannabis use. They provide important data that will be crucial for future new legislation.
Herba di Berna supports the scientific recording of consumer behavior in a controlled environment, as it contributes to safe and informed use. Projects like these can help to destigmatize cannabis use and at the same time establish clear guidelines for prevention and youth protection.
Conclusion
The increasing number of pilot studies shows that Switzerland is on the way to transparent and controlled cannabis regulation. We see this research as a great opportunity to better understand the market and offer targeted, health-beneficial products that promote responsible consumption. We support the approach of collecting science-based data to inform policy decisions and make consumption safer and more sustainable.
