Unity[1] is peer education project started in 1996 by Jaap Jamin at the large Amsterdam-based addiction prevention and treatment organisation Jellinek.
The observed high prevalence of substances in nightlife settings prompted the development of a new health promotion initiative: the Unity peer education project.
Although initially funded as a European Union project, as a best practice Unity quickly became a structural part of its mother organisation, Jellinek Prevention.
In 2011, Unity requested and was granted the quality label "well developed" by the Dutch health promotion watchdog organisation Centrum Gezond Leven.
Most of these targeted mainly knowledge and awareness, such as a movie explaining Dutch drug policy to tourists.
