Possession
Up to 10 g for personal use by adults is not punished.
Public use
Consumption brings a CHF 100 fixed fine for adults carrying under 10 g; trial participants may not use in public either.
Home grow
Growing THC cannabis, even for personal use, remains punishable.
Medical
Doctors may prescribe cannabis medicines without FOPH approval since August 1, 2022.
Pilot trials
Legal purchase only for enrolled adults (18+) in authorised trials, restricted to local residents; one trial per person.
Driving
Zero tolerance: 1.5 µg THC per liter of blood or more means unfit to drive; licence withdrawn for at least 3 months.

Can tourists buy cannabis in Zürich?

No. The city's FAQ is explicit that only Zürich residents take part. Tourists, commuters and people from the rest of the canton have no legal THC source; CBD shops sell hemp under 1% THC.

For everyone outside the study the national rules apply. The Federal Office of Public Health says cannabis with 1% THC or more is a narcotic; possessing up to 10 g for your own use is not prosecuted, but consuming can bring an on-the-spot fine.

Medical cannabis is a separate route: since August 2022 Swiss doctors can prescribe it without special permission from the Federal Office of Public Health. For how the other Swiss trials compare, read our Swiss pilot trials explainer.
