ABOUT US
Since 2017, COSN has led the effort to provide a statewide forum for all coalitions, organizations and individuals working to combat the opioid crisis in California. We are the largest opioid safety network in the country, with active coalitions serving 85% of California's 30 million people. We are now expanding our reach to bring our tools, training and resources to anyone working in opioid safety across the country.
OUR HISTORY
In 2015, the California Health Care Foundation (CHCF) developed a support network for the growing number of local opioid safety coalitions across California. An assessment led by the Public Health Institute demonstrated that counties with network-backed coalitions had a faster decline in opioid prescribing and nearly double the rate of addiction treatment. Backed with this evidence, COSN launched the Accelerator Program in 2017, dramatically increasing the impact of coalitions statewide.
OUR MISSION
Our mission is to build a movement to strengthen connections within communities. We believe that by working together, we can lower the supply of opioids, promote recovery from addiction, and prevent unnecessary deaths.
WHO WE ARE
We are a highly respected network for coalitions, organizations and individuals working at the forefront of the opioid epidemic. We provide access to the knowledge, training and resources to implement proven solutions that save lives.
