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.

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.
