Nikki de Graaf has been involved in Unity, a peer-to-peer harm reduction project, since 2015. Since this year she also provides communication training for Unity Netherlands. In this program she trains volunteers to talk to partygoers about the risks and effects of drugs. In addition, destigmatizing talking about drugs is important to convey. Nikki has been working as a coordinator for Unity Amsterdam since 2020 and also provides other communication training for outreach work that is useful for Unity volunteers. Various working methods have been developed for this in recent years, which we will talk about.
