Cocaine Urine Test

First and foremost, seeing how cocaine is illegal, if you find yourself frequently turning towards cocaine, perhaps you should consider visiting the Axis Residential Treatment site for a bit of insight. With that being said, Cocaine is usually processed by the body quite fast and regular urine testing is not likely to detect and cocaine presence. During urine cocaine testing, the doctors actually look for a substance called benzoylecgonine, which is often a sign that cocaine was present at one time.

The National Institute of Drug Abuse (NIDA) uses a concept called "minimum cutoff levels" to decide a positive drug test. Urine level of 300 micrograms per liter of benzoylecgonine is considered a positive result for cocaine use. Benzoylecgonine usually leaves the system after 3-5 days. In some cases it can stay in the body for up to two weeks, depending on the amount of drugs used and the individual's metabolic rate.

It is important to note that different individual have different metabolic speeds and processes, making the cutoff point somewhat too rigid. As concentration of urine with various other substances varies, so does the benzoylecgonine level vary with the many other factors that can change the makeup of the urine.

Avoiding Detection

Since cocaine is illegal, many people often try to avoid detection by submitting chemically made, fake pee called synthetic urine. It looks real, and people will accept it as a valid sample, but it is not real pee. Of course, people who get caught doing this often face all the following consequences. Nevertheless, use of synthetic urine is very common in people avoiding detection of cocaine in their urine sample. Of course, for this particular test, the people who administer the test know all the tricks and are not easily fooled.

Additionally, coke is metabolized by the body at a pretty rapid rate. So if you want to avoid detection and know your test date, you can either simply not take the drug for a significant enough amount of time before the test, or postpone the test if at all possible. Additionally, on the days before and during the test, people who want to avoid coke detection sometimes drink very many glasses of water so that their bladder fills up with mostly water, causing them to have a urinary urge and pee before the body can metabolize any significant amount of cocaine to be in that urine sample.

How Long Cocaine Stays in Urine

The common knowledge is that coke can be detected in pee for up to three to five days. In case of people using high doses of the substance, of course, the time period of metabolizing all the coke will be longer, from over a week to two weeks. There are some rare cases where cocaine use is detected at about the 3-week mark after use. What makes it difficult to determine the exact amount of time it takes for people to metabolize the drug is knowing exactly how much of it the people consumed of it in the first place, and how their bodies metabolize it since everyone's metabolism is a little bit different.

Other Tests To Detect Cocaine

Urine sample tests are not the only option and that is a good thing since as you see, the urine sample can be faked by presenting synthetic pee instead of real pee. The other common ways to test for cocaine use and coke presence in the system are hair sample tests, blood tests, and saliva tests.

Blood tests are most expensive and invasive, but they can determine whether the person is under the influence at that particular moment. It is also the most accurate test out of all the ways to determine cocaine use. The hair sample test that determines cocaine use is more expensive than the urine test, and can detect smaller traces of cocaine, and therefore gives positive results more often than the urine test. Saliva tests are also possible. They are not invasive and cheap. The only problem with it is that it can only detect cocaine 24 hours after it is used.

Due to variations of the substances in urine at different times of the day or after eating, drinking, or physical activities, there have been cases of positive test results after negative test results, with no additional cocaine consumed. Drinking large amounts of water or other fluids like green tea has been known as a somewhat effective way to delude urine concentration and pass a urine drug test.

Other possible substances that can be found in urine and dilute urine are

The over-the-counter tests that can determine whether chemicals like cocaine are present in urine are general urinalysis urine tests like the urine dipstick test. The urine dipstick test can detect many different chemicals and acid level balances.
