In 2018, COSN launched an Accelerator Program to support local coalitions to strive for greater impact within their communities. Our work is focused on preventing new addictions, increasing access to treatment and stopping overdose deaths. More than 30 coalitions share ideas, learn better methods, and discover the latest strategies to prevent new addictions, increase access to treatment, and stop overdose deaths.

California Opioid Safety Network (COSN) Accelerator 2.0 Cohort Program Application 

We are excited to release the application for the next phase of the California Opioid Safety Network (COSN) Accelerator 2.0 – a 12-month cohort program! 

Coalition teams will participate in a guided action-learning program that utilizes the actual work of each coalition as their learning ground to strengthen coalition capacity, infrastructure, and impact. There are two cohort groups - teams can choose to join a cohort focused on strengthening the core infrastructure of their coalition or one focused on advancing strategic partnerships. The program offers multiple components including monthly virtual workshops, customized tools and resources, coaching, and virtual convenings. 


All applications must be submitted no later than Friday, August 14 at 5:00 pm PT. 

Download the instructions for the online application here.


Each coalition brings together local leaders to implement community-driven initiatives that align with evidence-based practices. Because of California’s size and diversity, coalitions are developing innovations and solutions that can be translated to diverse communities across the country. Please see the map below to locate all of the coalitions that are in our Network, and a part of the Accelerator Program. 

50% Reduction in Opioid Prescribing in Outpatient Clinics

After generating their own set of safe prescribing guidelines, clinical champions in Monterey County lowered opioid prescribing and increased the use of non-opioid therapies by 300%.

“We would tell our colleagues, ‘please don’t use or reduce opioid [prescribing],’ and the response was ‘that’s fine, but when the patient is in pain, I have to do something –so can you please give me some options?’”

- Dr. Casey Grover,Chair, Emergency Medicine at the Community Hospital of the Monterey Peninsula

100 Overdoses Reversed in Two Rural Counties

By working in close partnership with local law enforcement, this coalition helped to ensure that all officers are equipped with naloxone, celebrating over 100 overdose reversals to date.

"With the distribution of Narcan kits to the local community, and the work of local leaders and coalition members, we are making a difference in the fight to end the opioid epidemic in Placer and Nevada Counties.”

- Quinn Gregory, Executive Director at Placer Nevada County Medical Society

From Zero to Multiple Addiction Treatment Providers

MAT services have successfully expanded into all four Northern Sierra counties, and buprenorphine prescribing rates now exceed the state average. See how four counties came together to launch a pilot suboxone clinic and support new MAT providers.

“Providing treatment is a small change for providers that makes a huge impact on people’s lives.”

- James Wilson, Coalition Coordinator & Health Education Coordinator for Plumas County
