Michael Brown Examines the Rise of “Ghost Networks” in the Narcotics Trade

Rigaku Analytical Devices' Global Director of Counter-Narcotics Technology, Michael W. Brown, examines how evolving cartel distribution networks are creating new challenges for law enforcement in a recent article published by Policing Insight.

In “Chasing ghosts: How cartels are reshaping the narcotics trade,” Brown describes a shift away from traditional, centralized cartel structures toward decentralized networks of small, semi-autonomous operators, or “micro-cells.” These fragmented networks can handle individual functions such as transportation, storage, recruitment, customer contact, or local distribution while maintaining limited knowledge of the broader organization.

This compartmentalized model can make criminal networks more resilient and significantly more difficult for investigators to map. Disrupting one cell may have little effect on the wider supply chain, while encrypted communications, digital platforms, and increasingly dispersed distribution channels can further complicate efforts to connect local activity with higher-level organizations.

Brown argues that addressing these evolving networks will require a more integrated, intelligence-driven approach. Greater information sharing across agencies and borders, advanced analytics, and emerging technologies such as artificial intelligence can help investigators identify relationships and patterns that may not be visible through individual cases alone.

Field-based presumptive chemical analysis can also contribute valuable information by helping officers rapidly characterize suspected substances encountered during investigations. When combined with location, timing, seizure information, and confirmatory laboratory findings, chemical identification data can help contribute to a broader intelligence picture.

Drawing on more than 32 years of experience with the U.S. Drug Enforcement Administration, Brown explores how law enforcement strategies may need to evolve alongside the criminal networks they are designed to disrupt.
