Success Story · County Health + State Education

Two places, one mission: how Sonoma County and Delaware both found Prevention kids didn’t tune out.

A county health department investing in every student before problems start. A state education agency reaching the students who need support most. Working independently, on opposite sides of the country, they arrived at the same answer.

Sonoma County and Delaware arrived at prevention from almost opposite directions: one delivering universal Tier 1 prevention countywide, the other offering targeted Tier 2 and 3 intervention to students already identified as at risk. Different institutions. Different scales. Different starting points — and one program that met them both exactly where they were.

Two places, one pattern

Delaware

Sonoma County

shift in beliefs about opioids/fentanyl’s addictive potential, same school

Two starting points: a county’s vision, a state’s program

Sonoma County, California

Sonoma County’s Department of Health Services (DHS) built its approach around a simple principle: invest upstream, before risk factors escalate, rather than respond only after problems emerge. DHS tracked youth health trends through the California Healthy Kids Survey and set out to find one comprehensive curriculum that could reach middle and high schoolers consistently across the county’s many districts — and their families too.

“Supporting our youth by empowering them with the information they need to make healthy choices is essential.”
Will Gayowski, Substance Use Disorders and Recovery Services Section Manager, Sonoma County DHS

Tier 1 · universal prevention Countywide

Delaware

Two thousand five hundred miles east, the Delaware Department of Education (DOE) chose a different path: a statewide mission “to empower every learner with the highest quality education,” carried out through its Substance Use Prevention & Intervention (SUPI) for Delaware Schools Program. The DOE brings IMPACT to schools as part of its Tier 2 and 3 track — targeted support for students who need more than a single universal lesson.

Different playbooks, same underlying belief: reach students with real information, and they make safer choices.

The shared solution: IMPACT

Both DHS and the DOE partnered with Panaptic to bring IMPACT, an evidence-informed, community-based curriculum, into their classrooms. The rollouts looked different. The reasons behind them did not.

Online, standalone courses any school staff can deliver — no original curriculum to build, no prevention expertise required. In Sonoma County, that meant a curriculum any of the county’s diverse districts could adopt without adding to teachers’ workload.

“Some school staff think they will have to create their own materials to launch IMPACT and are visibly relieved when they learn that these already exist.” — Peg Enslen

Family/Guardian and Educator courses sit alongside the Student courses. In Sonoma County, the Family course’s Spanish translation helped it reach the county’s large Hispanic and Latino population.

In Delaware, the Educator course gave staff a shared vocabulary: “All staff who take the course see what it’s about and start to use a common language. That’s huge.”

Both leaders chose IMPACT because it’s built on prevention science, not tradition — and both value the data it returns.

“There is a strong foundation in statistical analysis in the IMPACT program outcomes.” — Will Gayowski

“The schools’ annual IMPACT data is a great resource. It makes me feel so much better seeing the results.” — Peg Enslen

Proven at scale · 3,946 middle and high schoolers tracked, 2018–2026

Most one-time attitude-change interventions produce only a small effect (Albarracín & Shavitt,
Annual Review of Psychology, 2018). IMPACT students’ gains went well beyond that benchmark:

perceived addictive potential of cannabis

confidence understanding cannabis’s effects on brain development

confidence helping a peer with cannabis-related problems — a bystander outcome few curricula measure

perceived addictive potential of alcohol

perceived addictive potential of opioids/fentanyl

Multiples of the standard for meaningful prevention outcomes.

Backed by real partnership

Ask either leader what actually made the difference, and neither one leads with the curriculum.

The results: two places, one pattern

Sonoma County: countywide momentum

The clearest sign of success is how fast schools asked for more. When Panaptic launched new Alcohol and Opioids/Fentanyl courses in 2025, DHS brought them to Sonoma County schools right away.

Delaware: one school, a clear signal

At one Delaware school, the annual report showed the same kind of movement — and not just in the Marijuana course. Students rated all three courses “very helpful.”

growth in licenses in use, 2023–2025

confidence helping a friend struggling with substance use

understanding how marijuana and alcohol affect brain development

confidence using fentanyl test strips and Narcan to help a friend

rated IMPACT at least “helpful” for understanding effects on mental health, wellness, academics, and brain function

IMPACT is “an invaluable asset to our district,” with “excellent results.”

Matt Marshall, M.Ed., retired Director of Student Services, Cotati-Rohnert Park USD

Marijuana course — shift in beliefs about addictive potential

“I liked the in-depth explanations, especially about vaping.”

Alcohol course — shift in beliefs about addictive potential

“I liked learning the ways that alcohol actually affects your brain.”

Opioids/Fentanyl course — shift in beliefs about addictive potential

“This class taught me not to do opioids. I didn’t know about how risky it is to try them.”

A county that grew its licenses by 231% in two years. A school where nearly half of students shifted their beliefs about addiction after a single course. The metrics differ because the institutions differ. The pattern underneath does not: wherever prevention meets students where they are, with real information delivered well, it works.
