Applying prevention science to policy and practice around the world

In Memoriam: Jeff Lee (1950–2025)
One year on, we remember Jeff Lee, a pioneer whose life’s work helped shape substance use prevention as a professional, evidence-based, and humane field worldwide.
Jeff dedicated his career to strengthening the people behind prevention. He believed deeply in science, ethics, and collaboration, and worked across cultures and countries to elevate standards, build capacity, and connect professionals committed to protecting health and well-being.
More than his roles or titles, Jeff will be remembered for his generosity, his steady leadership, and his trust in the power of prevention done well. His influence lives on in the global workforce he helped strengthen, the practitioners he mentored, and the values he stood for.
He is missed.
He is remembered.
And his legacy continues.
And, as he always reminded us: keep smiling.

This Prevention Nugget explores what the Decade of the Child means for prevention professionals. It examines the gap between what science tells us children need and what systems currently deliver, highlights evidence-based and fidelity-driven approaches, and invites practitioners to reflect on system alignment, workforce capacity, and next steps to strengthen children’s health and wellbeing.

Our Scientific Advisors Say...
“Which prevention programs and policies are truly worthy of being considered “evidence-based”? I’ve been thinking about the answer to this challenging question for decades. The difference between what can – and what should not – be called “evidence-based” is often critical, if we are to avoid wasting the limited available resources we can expend on prevention. But that difference is often difficult to discern, and as evidence accumulates over time the status of a given program and policy may well change. Sifting through the evidence on a continuing basis, and making recommendations as to what should and should not be implemented, is the job of the entire community involved in the application of prevention science.”
