Overview of authorised pilot trials with cannabis

Several pilot trials are currently underway with cannabis for non-medical purposes. The following overview provides information on the most important key data.

In Switzerland, pilot trials with cannabis are planned in all major cities. The various organisers are planning to distribute cannabis in pharmacies, cannabis social clubs and non-profit stores as well as via other distribution channels. The pilot trials will thus allow for, among other things, a compari-son of the different distribution systems and show which regulatory models are accepted by consumers and the population. 

Timeline for the pilot trial

Those responsible for the pilot trials are required to inform the FOPH annually about their progress. The FOPH will provide information to the public based on this feedback (Pilot trials with cannabis (admin.ch)).

The research reports on the individual pilot trials will be published on this page:
