Cannabis pilot trials

The pilot projects are scientific studies designed to gain insights into the effects of the regulated use of cannabis for non-medical purposes.

The first cannabis pilot projects are currently underway in various Swiss cities. Basel-Stadt launched the first project at the end of January 2023. Since then, the city of Zurich has followed suit with “Züri Can” in August 2023 and there has been another project covering the canton of Zurich (including Zurich and Winterthur itself) since May 2024.

The results of the studies will then be incorporated into political developments (see parliamentary initiative). Until then, participants will enjoy access to legal cannabis flowers and hash from Swiss organic outdoor cultivation. In return, they fill out a questionnaire every six months about their consumption habits, state of health, etc.

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).

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 hanfstueb.li!

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.
