Key GPHN Projects and Activities

We employ an inclusive approach, seeking to engage the widest possible range of stakeholders active in the public health and harm reduction arena. We want to work with people who deliver services and interventions, people who receive services and interventions, NGOs, community projects, advocacy groups, academics and policy makers. We all have things to learn from one another - and we want to help you to have the conversations that matter.

Information Sharing

Our goal is to help the members of our network share information about their projects, good practices, and ideas, and provide them with access to organized and relevant materials. We also support the visibility and online presence of NGOs.


Our goal is to spread knowledge and information about good practices in public health, based on evidence from harm reduction, for both experts and the public.

Public Events

We specialize in supporting and running international public health events for experts, policy-makers, academics, and NGOs. We work with global leaders in the public health and harm reduction fields.


Our network gives an opportunity for our community to exchange ideas. We organize conferences and events, and provide an online platform to exchange and promote ideas.
