The local government has a zero tolerance policy with regard to all types of soft and hard drugs. When violations are established by the police, an immediate amicable settlement will be proposed for limited user quantities, which means that the fine that is imposed must be paid immediately before you can re-enter the venue.
If you refuse or are unable to do so, an official report will be sent to the public prosecutor's office and you risk prosecution. Larger quantities will in any case lead to legal prosecution and denial of access to the venue or removal from the venue.
Anyone who needs to have certain medication with them can take it with them on presentation of a doctor's certificate.
