Framing the seriousness of drug smuggling in Sabah: enforcement paradoxes, borderland economies, and regional drug flows in Malaysia

Drug smuggling in Sabah has become a persistent and structurally embedded challenge that extends beyond routine border crime and conventional enforcement evaluation. Building on Malaysia’s longer historical drug trajectory and Sabah’s position within a maritime borderland connecting Malaysia, Indonesia, and the southern Philippines, this study argues that the seriousness of the issue cannot be measured through seizures and arrests alone but must be understood through a multi-lens framing that captures enforcement, societal, and systemic dimensions. Drawing on a social constructivist approach and qualitative methods, the study employs in-depth semi-structured interviews with operational enforcement officers and strategic-level key persons from multiple agencies, supported by document and field-based contextual analysis. Findings indicate that the seriousness of drug smuggling is shaped by four interrelated indicators: (1) persistent inflow despite continuous enforcement, (2) multi-route operations reflecting organised supply resilience, (3) escalating scale and value of seizures, interpreted as evidence of sustained volume rather than control, and (4) Sabah’s structural role as an entry and transit gateway with national spillover risks. The discussion highlights an enforcement paradox in which visible operational outputs may coexist with enduring system-level vulnerability. The study concludes that effective responses require reframing how seriousness is understood through flow-based and system-level indicators, supported by integrated governance, intelligence-led coordination, adaptive legal and technological capacity, and strengthened regional cooperation to disrupt transnational supply chains and reduce long-term harm.
