Which prevention strategies are most effective for reducing youth substance use?

• A. Strict punitive policing with curfews alone.
• B. Comprehensive, evidence-based programs that combine school, family, and community approaches; universal and targeted interventions show effectiveness.
• C. Media campaigns only.
• D. Pharmacological prevention.

Answer: (B)

Prevention works best when it targets the whole environment that influences youth, building skills, changing norms, and providing ongoing support. A comprehensive, evidence-based approach combines school programs, family involvement, and community efforts, and uses both universal strategies (for all youths) and targeted interventions (for those at higher risk). This multi-component plan addresses a range of risk factors—like peer pressure, lack of skills to say no, and poor family communication—while boosting protective factors such as social competence, parental monitoring, and positive peer networks. When these elements are aligned, they reinforce each other, leading to meaningful and lasting reductions in initiation and use across substances.

Relying on punitive policing with curfews alone misses these underlying factors and can erode trust without changing youths’ decision-making skills or the environment that enables use. Media campaigns by themselves can raise awareness but often don’t produce sustained behavior change unless paired with skill-building and environmental supports. Pharmacological prevention isn’t a practical or established approach for preventing youth substance use at the population level.
