  • Program Support Packages: NASEN is one of the only sources of syringe exchange start-up assistance for new programs with little or no operational history.
  • U.S. Syringe Exchange Directory: The purpose of NASEN's U.S. Syringe Exchange Directory is to facilitate communication and networking among SEPs

  • Loan Assistance: NASEN provides short-term loans or credit with BC when a SEP is waiting for a grant award letter, or when a program struggling with funding so it is not forced to curtail or cease operations.
  • Dave Purchase Memorial Syringe Exchange Survey: NASEN collaborates annually with the Beth Israel Medical Center (BIMC) to conduct the most comprehensive national survey of SEPs.

What is the Clearinghouse?
The California Syringe Exchange Supply Clearinghouse was established in 2016, following the passage of a bill that authorized funding for the establishment of a Clearinghouse to help California SEPs enhance the health and wellness of people who inject drugs. The Clearinghouse aims to increase the organizational stability of California SEPs by ensuring access to a baseline level of supplies for authorized SEPs.

Who operates the Clearinghouse?
The Clearinghouse is operated by the North American Syringe Exchange Network (NASEN), in partnership with the California Department of Public Health (CDPH), Center for Infectious Diseases (CID), Office of AIDS (OA).

NASEN is a Purchase Project, operated by Dave Purchase Project. Dave Purchase Project also operates a syringe exchange program in Pierce County, WA: Tacoma Needle Exchange.
