Urine Cocaine Test

The way that the urine cocaine test will discover that cocaine has been used is through finding amounts of the cocaine metabolite – benzoylecgonine. At least 300 nanograms to the millilitre of urine must be discovered of this drug metabolite to actually be able to concur that the fault is from using cocaine or crack.

The amount of nanograms of this drug metabolite in your urine cocaine test sample depends a lot on when the urine sample is taken. The first urination of the day will always yield the strongest concentration of drug metabolites. If you wait a few urinations through the day, the concentration (assuming nothing interferes) will lower. The higher that the concentration of the drug metabolite is the more evident that it is that the particular drug (in this case cocaine) is being used by the person getting tested.
Since the concentration of the cocaine metabolite in a urine cocaine test sample will vary for per urination throughout the day, it is possible that the test reports back with a false negative – meaning that the test read no drug use even if there was because of the low concentration found. Most people, prior to testing, will dilute their urine so the concentration level lowers when they provide the urine cocaine test sample.

It usually takes the cocaine metabolite about 5 days for it to fully get out of your system. The time frame can change depending on how often and how heavily that you use the drug. Various studies have found that a good time frame estimate would be 10-21 days and the higher end is for the more severe cases.

There are ways that you can pass a urine cocaine drug test but you have to go about it the right way. The methods of cheating the cocaine test that work the best would include: fake or synthetic urine, diluting your urine, sneaking in someone else’s urine that won’t test positive. Since these tests are usually in private, having a small bottle of someone else’s urine may go unnoticed. The cocaine tests are usually very accurate and are fairly hard to fool.
