Overview
Benzoylecgonine is the primary metabolite of cocaine — more stable in the aquatic environment than cocaine itself and therefore a better WBE indicator. It is consistently detected at higher concentrations than cocaine in European surface waters.
Health Relevance
Not pharmacologically active. No known health effects at environmental concentrations.

Controversy & Contested Science
EMCDDA WBE data document a sustained increase in European cocaine use since 2010, correlating with increased South American supply routes through West African trafficking networks. Wastewater data provided the first systematic real-time evidence of this trend — before traditional household survey epidemiology detected the shift. This intelligence advantage has driven EU law enforcement to invest significantly in WBE monitoring for criminal intelligence purposes — raising questions about dual-use of public health surveillance infrastructure.
