Cocaine Drug Test

Cocaine addiction is one of the most pressing issues for the drug enforcement agencies around the planet, and this is because of the highly addictive and harmful dual nature of this drug on the addicts.

Addicts prefer to take this drug through a number of routes ranging from snorting its powdered form through their nostrils, or injecting it directly into their bloodstream. Other preferred routes include smoking it, or rubbing it on the gums and teeth. Irrespective of the preferred route of administration, cocaine produces a wide range of effects on the users that affects the central nervous system and a host of other organ systems. Therefore, it has become essential for the law enforcers to utilize cocaine drug test to be able to detect instances of cocaine abuse in suspected addicts.

The cocaine drug test is capable of detecting minute levels of the active chemical of cocaine, and its metabolic byproduct benzoylecgonine in the test samples derived from the suspected users. In fact, any such cocaine test can make use of a variety of samples include blood, urine, hair, and sweat patch for effective detection of this drug in the body of a suspected user.


Cocaine Drug Test



Cocaine Urine Test

Urine samples can be an excellent choice for the confirmation of cocaine usage in any suspected user because of its low cost and non-invasive nature. Availing a urine sample is quite easy, and this cocaine drug test can yield reliable result for the law enforcers to work with. The cocaine urine test consist of trying to detect the presence of the metabolic byproduct of the active chemical of cocaine in the urine sample, with the ratio between the drug and its metabolized byproducts providing a scope for estimating the time elapsed since latest exposure.

The duration for which traces of cocaine remains within the urine of regular users depends upon a number of factors such as the potency and amount of drug taken, frequency of use, as well as, their gender, age, metabolic rate, and general health. Moreover, the route of administration plays a significant role in determining the longevity of the drug in the urine of any user, with snorting carrying the traces of metabolites for up to a day after a single dose, while injecting raises that period considerably. Therefore, the cocaine urine test can be an excellent option for detecting the presence of cocaine without being invasive or exceedingly costly to operate.


Cocaine Hair Test

Hair sample also provide an excellent option for the detection of cocaine usage in any suspected addict, because the metabolites of this drug shows up in the hair shaft within a few hours from the time of latest usage. In fact, the metabolites can become present in detectable quantities within 8 hours from the time of latest exposure to cocaine, while it can last for 7 to 10 days after use in one-off cases. However, regular users of cocaine will find it more difficult to get rid of the traces of drug abuse in their hair because it can then last for as long as 90 days for regular users until the affected hair follicles are cut off. Thus, the cocaine hair test is a highly effective detection technique and convenient as well because of its non-invasive nature.

The cocaine hair test requires only about 60 mg of hair sample, which roughly equals around 90 to 120 strands of hair, with a length of at least 1.5 inches or 3.9 cm from the scalp. Procuring this tiny amount of hair from any suspect is bound to be extremely easy for the law enforcers, and can provide them with accurate results regarding suspect cocaine abuse. While contamination from external environment can lead to presence of low levels of cocaine on the hair shafts, and regular washing and shampooing can remove some of those traces from regular users, this cocaine test examines presence of the metabolites inside the shaft to discount all such possibilities.


Cocaine Blood Test

The presence of cocaine in the blood sample is quite brief, but this is because of its extremely short half-life of around 0.8 to 0.2 hours. However, that does not mean drawing of a blood sample is not going to produce any yield because the half-life of benzoylecgonine, which is the metabolized byproduct of the active chemical of cocaine, is as high as 6 to 7 hours. Therefore, it becomes possible to detect traces of the metabolites of cocaine in the blood samples for several hours from the time of the latest exposure to this drug, which makes the cocaine blood test as the cocaine drug test which is the most accurate of all the drug tests available for detecting this drug.

Several factors determine the duration of the presence of cocaine in the bloodstream, with the route of usage, along with the dosage and frequency of use being the most significant ones. The metabolites are likely to remain in detectable levels in the bloodstream for considerably longer in case of chronic users of cocaine. Thus, regular users about to appear for any such cocaine test need to keep these factors in mind if they wish to emerge from the cocaine blood test with clean record.

Sweat Patch Test

The sweat patch test has attained greater popularity in the recent past for the accurate detection of the instance of cocaine abuse in the suspected users. This cocaine test consist of placing a patch, which is much like a simple band-aid in its visual appearance on the skin surface, and keeping it there for round about 14 days. The patch is capable of detecting the presence of the drug cocaine, as well as, its various metabolic byproducts in the perspiration of the person on whose skin surface it rests.

The most popular part on the skin surface preferred from attaching this patch is the upper arm area, where it is placed after thorough cleansing of the skin surface. After having kept the patch at the spot for the requisite number of days, it is sent to the laboratory for testing with advanced analytical techniques such as Gas Chromatography – Mass Spectroscopy system. However, various factors such as dosage and frequency of use, as well as, the level of hydration can have considerable effects on this cocaine drug test.

If your looking to quit cocaine, or scheduled to take a cocaine drug test in the near future for employment or medical purposes, then a full body detox should be considered. There are a number of natural remedies that you can do from home, to fully cleanse your body from the inside.
