Eastern Washington Overdose Collaborative

Empowering local efforts with regional resources

Education, Networking, Sharing, Support.

The purpose of Washington Poison Center’s Eastern Washington Overdose Collaborative (EWOC) is to create a space for communities in Central and Eastern Washington to share locally-relevant resources, connections, and high-quality information needed to address substance use and prevent overdose.

We typically meet every other month. Our meetings feature an expert presenting on a relevant and timely topic, group discussion, and opportunities for members to share their work and collaborate on projects.

Want to connect? Contact Justin Mauger, our Central & Eastern Washington Community Health Educator (jmauger@wapc.org) or sign up for email updates.
