A policy review argued that youth drug prevention has been ineffective due to simplistic messaging and recommended adopting the Institute of Medicine's three-tiered prevention model with Student Assistance Programs and community coalitions.
Educators, policymakers, and parents interested in effective approaches to youth drug prevention.
Three-tiered prevention: universal, selective (high-risk groups), indicated (manifest risk)
What the researchers found
This policy review critiqued traditional approaches to youth drug prevention as overly simplistic, relying on exaggerated risk messaging and one-size-fits-all abstinence approaches that are not grounded in science.
The authors recommended the Institute of Medicine's 1994 continuum of care model, which divides prevention into three tiers: universal prevention (broad population-level programs), selective prevention (targeting high-risk subgroups), and indicated prevention (for individuals already showing risk behaviors).
They highlighted Student Assistance Programs (SAPs) in high schools and community coalitions as practical examples of how this tiered model can be implemented. They also advocated for stable marijuana tax funding to support these programs.
Why it matters
Drug prevention programs have consumed significant resources with limited success. Tailoring prevention intensity to individual risk levels, rather than delivering the same message to everyone, is a more evidence-informed approach that could improve outcomes.
The numbers in context
The Institute of Medicine model was developed in 1994. Three tiers: universal, selective, indicated. No specific outcome data were presented in this review.
How the study worked
Policy review published in the Journal of Psychoactive Drugs, examining the evidence base for different prevention approaches and recommending a framework for implementation.
What this study cannot tell us
This was a policy opinion piece rather than a systematic evaluation of prevention program effectiveness. It did not present outcome data comparing tiered versus non-tiered prevention approaches. Implementation challenges and costs of the recommended model were not fully addressed.
How to read the evidence
This is a policy review presenting a framework for prevention rather than new research data.
When this study was published
Published in 2016. Some jurisdictions have since implemented tiered prevention models funded by cannabis tax revenue.
The bigger picture
As cannabis legalization expands, the question of how to prevent or reduce youth use becomes more pressing. This review argued that the answer is not more of the same simplistic messaging, but rather a more sophisticated, tiered approach that addresses different levels of risk.
Questions still open
- How effective are Student Assistance Programs at reducing youth cannabis use? Can marijuana tax revenue reliably fund prevention programs long-term?
Common questions
Why haven't "Just Say No" programs worked?
What is a Student Assistance Program?
