COVID-19 Response — Due to the evolving COVID-19 outbreak, particularly in Washington state, please be aware that our staffing and operations may be impacted for the next several weeks. We value your business and will respond to inquiries and issues as best we can and we appreciate your patience while we work through this ever changing situation. Updates
We believe that drug users and other vulnerable people matter. They're sons, daughters, sisters, brothers, moms, dads, and grandparents. Each one is "somebody's someone" – and should be treated as such.

We are sickened at the continued murder of black people in this country, including at the hands of law enforcement. We are disgusted that a system that excuses and perpetuates this violence exists at all, particularly in America. The loss of George Floyd and too many others is a tragedy. Black lives matter.

At Dave Purchase Project, we are dedicated to addressing inequality and inequity with particular attention to disparities in health, especially those of marginalized populations. This has been and continues to be essential work. We are committed to making this country a healthier place for all.

Our Story

With the first legal needle exchange in the country and the only at-cost harm-reduction supply co-op, the Dave Purchase Project helps lead and supply the harm-reduction movement. Formerly known as Point Defiance AIDS Projects, we started with a simple idea — drug users matter and are key to stopping the spread of AIDS. Our founder, Dave Purchase, was right. Needle exchanges have drastically reduced the spread of HIV. And now, with your help, we’re taking on everything from the opioid epidemic to the resurgence of hepatitis.
