As with most European countries, nightlife in Flanders (especially in the electronic dance scene) is booming business and 50% of clubbers use one or more illegal drugs when out at night.


Partywise aims to encourage party people to be responsible during a night out. It tries to inform and sensitise clubbers in different ways, so that they can make responsible choices.


Partywise is a prevention concept using a campaign and other materials to inform and sensitise clubbers, and brochures, materials and training sessions for prevention workers and nightlife professionals.


The process evaluation showed a very positive result for the different aspects of Partywise. In general, clubbers liked the look and feel of Partywise and could understand the information disseminated. The majority of clubbers thought that initiatives like partywise were nessesary.


Partywise is a good project to inform and sensitise young clubbers about health risks in the nightlife environment. It is not currently known whether Partwise leads people to change their behaviour. However, through the intervention, revellers know what the risks are and they can choose for themselves if they want to take these risks or not.
