The document is not really nice, admittedly. Neither from the quality of the copy, nor from the content: Because Zurich still fines with 258 francs, if someone is picked up for the first time with some THC-containing material. And this time it was only one joint that was involved. Even if it was smoked in front of the police. What a shame!
The actual fine is 100 francs, which is the same in other areas of Switzerland. But no one except Zurich manages to charge such high incidental costs.
