Benzoylecgonine is a urinary metabolite used to indicate exposure to which drug?

Explanation:
Benzoylecgonine is the urinary metabolite that signals cocaine exposure. When cocaine is processed in the body, it is rapidly broken down, and benzoylecgonine is formed and excreted in urine. This metabolite is more stable and detectable for a longer period than cocaine itself, making it a reliable marker for cocaine use in drug screens. Other drugs listed have different metabolic byproducts, so finding benzoylecgonine specifically points to cocaine rather than codeine, amphetamine, or propoxyphene.
