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.
