Cannabis pilot trials

The first cannabis pilot project started in Basel-Stadt on January 30, 2023! A total of 374 study participants can obtain legal cannabis there. In August 2023, the city of Zurich followed suit, offering space for over 2,000 participants in the “Züri Can” pilot project.

The pilot projects are scientific studies to gain knowledge about the effects of a regulated use of cannabis for non-medical purposes.

Since mid-May 2021, the law article on cannabis pilot trials and the ordinance have come into force. Applications for pilot trials can now be submitted to the Federal Office of Public Health (FOPH).

Status Legalize it Social Club

We run one of the 10 social clubs together with the city of Zurich, our Hanfstübli.

We have been selling study cannabis to participants since August 2023. We are also still accepting new study participants.

You can sign up for the study at!

Since 2005 there have been many discussions whether experimental projects with actually prohibited hemp (1% THC and more) should and could be carried out. Now the parliamentary consultations on this have been concluded in September 2020.
