North America Syringe Exchange Network

Saving lives by connecting people and programs with the resources they need to reduce harm.

NASEN is an initiative of the Dave Purchase Project

NASEN was formed in 1992, to support SEPs and to encourage the expansion of a network of organizations and individuals that advocate for syringe exchange. It is the first, largest, and only, at-cost supplier of harm reduction materials in the US. In 2018, NASEN’s acquired and distributed approximately $10M worth of harm reduction supplies on the behalf of 400 SEPs in the US, Puerto Rico, and the US Virgin Islands. NASEN provided material support valued at $25K to 28 newly emerging and/or struggling SEPs via program support packages (formerly known as start-up grants).
