How long does Benzoylecgonine stay in the hair?Benzoylecgonine is the substance that is left behind after cocaine use. How often and the amount of cocaine used is what determines how long this metabolite is detectable in some areas of the body. For instance, if cocaine was used once the metabolites could be detected in the blood up to two days. It can be traced in the urine for about three days. New follicles can take up to seven days to grow. Typically it can take up to 90 days for enough hair to grow before there is enough to test for Benzoylecgonine. Since each individual’s hair grows at a different rate, the detection period could vary as well.
Can Benzoylecgonine stay in urine longer than blood?After cocaine has entered the body it is passed through system until it hits the liver. Once it reaches the liver it metabolizes into a substance called Benzoylecgonine. This metabolite is what is detected and causes drug tests to have a positive result for cocaine. Cocaine itself can only be detected for up to twelve hours in the blood whereas, the metabolites can be detectable for as long as 48 hours. When the drug testing is done by aurine analysis the metabolites can be detected for up to 72 hours. With those who are heavy users of cocaine, this detection period can be much longer.
Can Esterom test positive for Benzoylecgonine?Benzoylecgonine is one of the main ingredients in the medication Esterom. It is also the metabolite that is tested for when being tested for traces of cocaine. So this medication can lead a test to show a positive result for Benzoylecgonine (Cocaine). Esterom is illegal in the United States if the metabolites are detected by a drug test it will not be considered a medical reason. Since it is illegal in the state there haven’t been any studiesperformed for how long it would stay in the system. However, Benzoylecgonine is the common factor between Esterom and Cocaine. So, in theory, this medication should metabolize and pass through the body in the same way.
What time of day should Benzoylecgonine be tested for?Recent studies have indicated that Benzoylecgonine can be found in the urine much longer than historically believed. This was discovered while studying patients who chronic abusers of cocaine. However, the urine analysis which is most often used by employers only tests for the most recent use of this drug. These are the lowest grade urine tests approved by the NIDA (National Institute of Drug Abuse). With these tests a metabolite level of 300 nanograms per liter of urine would be enough to test positive for Benzoylecgonine. However, result can vary depending on when the test is given. If the test has collected the first urination of the day it will show the most concentrated sample. This will be the best time of the day to collect a sample to get the best result. The components of urine will change as the day passes which can lead to different results.
Can saliva be used to test for Benzoylecgonine?There have been many studies to determine an accurate length of time that Benzoylecgonine can be detected in saliva. Swabs were used to collect saliva from the mouths of 69 patients who had used Cocaine within a 24 hour period. The swabs were then sent off for analysis. When the results came back they were compared to result from blood and urine tests. There were a small percentage of the urine samples that came back free from Cocaine and its metabolites. All of these saliva samples tested positive for both Cocaine and Benzoylecgonine. The same can be said with the urine samples. So the popular belief given these results is that saliva is a suitable method for detecting Cocaine and its metabolite Benzoylecgonine.
Benzoylecgonine is a metabolite that is left in the body during Cocaine use. Drug analysis tests for to determine if cocaine has been used. This is because the metabolites remain in the body longer than the drug itself. There is no real way of knowing just how long these metabolites can remain in the body, because different tests can detect for different amounts of time.
