When cocaine is consumed with alcohol, it creates the metabolite, coca-ethylene, a much more powerful and difficult to expel substance. The major advantage of BE screening is that many commercial immunoassays are designed to detect BE.вЂќ Urine testing for other cocaine metabolites has evolved with the presence of nearly 15 different metabolites revealing cocaine abuse although not all of these tests are feasible for reasons such as costs. Cocaine Urinalysis TestingДЄccording to the Office of the Chief Medical Examiner, State of Maryland, Baltimore, MD, вЂњThe two major urinary metabolites of cocaine are benzoylecgonine (BE) and ecgonine methyl ester (EME). The cocaine alkaloid, itself, has a very short half-life and generally becomes undetectable within 24 hours while the metabolites of cocaine can be detected in the urine for several days or even weeks depending on the individual and the type of test being performed. Common Variable FactorsД¬ocaine abusers use cocaine in a variety of forms, purities, amounts, frequencies, and methods of ingestion which plays an active role in how the cocaine is absorbed, metabolized, and excreted in the urine. Understanding these issues may help with the calculations. There are many influential factors that can predispose a person to slower elimination of cocaine and its metabolites. Most of these calculations rely on the individual and their usage history along with the type of urinalysis test being performed. There is no absolute standard for measuring how long cocaine stays in a personвЂ™s urine. How Long Does Cocaine Stay in Your Urine?
