Cocaine, which is chemically known as benzoylmethylecgonine, typically lasts for 12 hours in the body, or up to 72 hours (three days) in the case of heavy use. This means that cocaethylene will totally be undetectable in the urine, just after three days of its last use, but there is a problem.
During the process of breaking down benzoylmethylecgonine, the liver converts the cocaine into metabolites. Metabolites are substances which are necessary for metabolism in the body.
The primary metabolite of cocaine is benzoylecgonine, and it remains in the body much longer than cocaethylene does.
For this reason, cocaine tests actually test for benzoylecgonine, cocaine’s metabolite, and not for benzoylmethylecgonine, which is crack itself.
How Testing For Cocaine Works
In order to test positive for benzoylmethylecgonine use, you will have to have 300 nanograms or more, of the metabolite, benzoylecgonine per milliliter. This can also be stated as 300 micrograms per liter.
Due to the way the body functions, the first pee of the day should contain the highest concentration levels of the metabolite. Many drug tests will just screen for benzoylecgonine or cocaethylene, but there is another metabolite that gets formed when either cocaine of benzoylecgonine mixes with alcohol in the liver.
This second metabolite is called cocaethylene and usually takes twice as long to be eliminated from the body.
How Long is Cocaine Detectable in Blood?
Without any tolerance whatsoever, meaning for first time users, it may take up to 48 hours for the substance to leave your bloodstream after using. Although, if you are a consistent user and have developed a tolerance for it, then that's a completely different story.
It will be very hard to tell if cocaine is still detectable in your blood or not because there have been cases where it wasn't detected even after using for a long time. There also have been cases where it was detected easily after using it only once or a few times. The only way to know for sure is to test for it yourself using at-home drug testing kits.
How Long is Cocaine Detectable in your Hair?
This is a tricky one, because just like with other substances, the concentrations are going to be detectable for another 90 days or so. The main issue is not at the tip of your hair but mostly on the other areas of your hair. What this means for you is that, it will stay there until that part is cut off or if the hair completely falls off.
How Long is Benzoylecgonine Detectable in Urine?
Cocaine’s metabolite is detectable in the pee, starting from 2 to 5 hours after use, until 3 to 5 days for a one-time regular use. If the dosage was high, then it could be detectable for 3 to 7 days. For chronic users, the benzoylmethylecgonine metabolite can be detected for up to 14 days after the last use.
Urine detection time-frame for different user levels:
Higher doses and chronic use lengthens the detection period because, the higher concentration of cocaine metabolites need longer periods of time to be eliminated, and the body will even store some of these metabolites in fat cells, in cases of chronic use.
- One time User: 3 to 5 days
- High Dosage Use: 3 to 7 days
- Chronic Users: 5 to 14 days
How To Pass Your Urine Test?
Because most drug tests come unannounced, some people find it challenging as they do not have time to wait out the natural detox period. To pass the test, they would sometimes go for synthetic products like a fake pee or proceed with a much quicker yet still natural way of detoxifying themselves before going to the battlefield.
But, the problem with synthetic urine is that it takes time to prepare and heat it up to a temperature that is almost the same as a natural pee and that makes it difficult to carry out during random drug testing. Also, companies now adopt a more strict drug test wherein personnel will have to oversee the sampling stage to make sure that what you’re submitting is authentic.
That is why most people go for the latter instead - detox drinks. Detox drinks, when taken fresh, are believed to help people pass their random drug tests. Just see to it that you follow the instructions and timeline of taking it carefully. This way you won’t have to worry about going into the drug testing venue and trouble yourself with concealing and submitting a fake pee.
Factors that affect Substance Detection:
Since the human body is an organism, there are many other factors that affect the exact elimination time-frame, other than just the level of benzoylmethylecgonine use. These methods are listed below, along with their effects on the overall metabolic process:
1) Body Weight
Heavy people tend to have slower metabolic rates. This means that a more physically active person will get rid of the crack metabolites faster than an overweight individual.
2) Quantity Used
The amount of benzoylmethylecgonine consumed is also important in determining how long it takes for the cocaine metabolites to be flushed out. More benzoylmethylecgonine simply requires more time to be eliminated by the liver.
3) Presence of Alcohol
The consumption of alcohol can further complicate issues because a new substance gets formed in the liver, whenever alcohol and benzoylmethylecgonine are both present in the bloodstream. This substance is called cocaethylene, and it lasts even twice as longer in the body, as the other metabolite.
As you can see, there is no single and straight answer to the question of how long benzoylmethylecgonine use can be detected through a pee test. One should consider the individual metabolic rate, the quantity used, and of course, the presence or absence of alcohol in the system. This means that you can be free in as little as three days, or it could take as long as 2 good weeks.
But there’s no need to worry as you can always have options to help you keep your job.
When in doubt, always have a backup plan and taking detox drinks regularly may be one of them. Detox drinks such as Rescue Cleanse help with flushing toxins and other urine-based drugs out of your system. It’s also a bonus that you keep your body in good shape by just consuming them.
