Substance Abuse and its Implications for National Security and Development in Nigeria

Substance abuse has emerged as a multidimensional challenge with significant implications for national security, human security and sustainable development in Nigeria. Beyond its consequences for individual health, the misuse of psychoactive substances can weaken human capital, increase criminality, undermine social cohesion, place pressure on public institutions and contribute to insecurity. This study examines the implications of substance abuse for national security and development in Nigeria. It adopts a qualitative documentary research design and analyses relevant scholarly literature, government reports, international publications and empirical studies on substance use, crime, health, youth vulnerability, treatment capacity and socioeconomic development. Evidence indicates that Nigeria faces a substantial burden of non-medical drug use, particularly involving cannabis, pharmaceutical opioids, tramadol and codeine-containing preparations. The problem is particularly significant among young people, whose health, educational attainment, productivity and future contribution to national development may be affected. The study further argues that substance abuse can interact with poverty, unemployment, criminal networks, violence and weak institutional capacity, creating a reinforcing cycle of insecurity and underdevelopment. The paper concludes that substance abuse should be treated not merely as a public-health problem but as a national-security and development concern. It recommends integrated prevention, treatment, rehabilitation, intelligence-led drug-control measures, youth employment, community-based interventions and stronger inter-agency coordination.
