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

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.
