Beyond Awareness Campaigns: Rethinking Adolescent Drug Abuse Prevention Through a Continuous Behavioral Engagement Framework in Nigeria

Adolescent drug abuse prevention in many African settings remains largely dependent on episodic awareness campaigns and school-based sensitization activities. Although these interventions improve knowledge, they often demonstrate limited effectiveness in producing sustained behavioral change. This paper examines this gap by situating adolescent substance use within continuous neurobehavioral, social, and digitally mediated influence systems that extend beyond discrete prevention encounters. Drawing on contemporary evidence from adolescent neurodevelopment, peer influence research, digital behavior environments, and prevention science, the paper argues that substance-use behaviors are shaped through ongoing reinforcement processes embedded in peer networks, emotional regulation dynamics, community contexts, and digital interaction spaces. A key limitation identified is prevention discontinuity, where intermittent intervention strategies are misaligned with the continuous nature of behavioral reinforcement shaping adolescent decision-making. In response, the paper proposes a continuous behavioral engagement model, reframing prevention as a longitudinal, systems-based approach that integrates community structures, low-barrier digital communication pathways, behavioral reinforcement mechanisms, and early mental health engagement. The model does not replace existing interventions but extends them through sustained engagement across the environments where adolescent behavior is continuously formed. This reconceptualisation has important implications for health systems design, digital health integration, and prevention policy, supporting a shift from episodic awareness strategies toward continuous behavioral engagement frameworks for adolescent substance-use prevention.
