Cocaine and Metabolite

Interpretation

  • The presence of cocaine >LOQ indicates exposure to cocaine within 1 day prior to specimen collection.
  • The presence of benzoylecgonine >LOQ indicates exposure to cocaine within 5 days prior to specimen collection.

 

Metabolites

  • Cocaine is metabolized to several inactive metabolites, the predominant one being benzoylecgonine.

    Cocaine → Benzoylecgonine

Confirmation Tests:

Approximate Detection Times

Cocaine & Metabolite LOQ (ng/mL) Detection Time* up to
Cocaine 50 <1 day
Benzoylecgonine 50 5 days
*These are approximate detection times for the drug or metabolites in urine. The actual detection time depends on dose, frequency of use, and individual metabolism.
