“Our approach places the health of cannabis users at the centre and shows that modern prevention work can go hand in hand with controlled access to cannabis products,” declared Andreas Hauri, a member of the city government in charge of public health, in a press release issued on Thursday by the city of Zurich, the University of Zurich and the University Psychiatric Clinic Zurich.

Around 2,100 people have taken part in the pilot project approved by the Swiss federal authorities. Of these, 150 people have stopped participating. Over half of participants consume cannabis at least four times a week.
