What do drug tests look for

When cocaine gets to the liver, it is metabolized into 8 metabolites, of which Benzoylecgonine and ecgonine methyl ester is the most common.

Of the 2 metabolites mentioned above, lab tests mostly look for Benzoylecgonine due to its long half-life of up to 12 hours. This long shelf-life is what makes cocaine stay in your system in the urine for 3 to 4 days among occasional users and up to 6 weeks among chronic users.

Cocaine in saliva can be detected for 5-12 hours, while its metabolites, mainly benzoylecgonine, is persistently detectable in saliva for between 12 and 24 hours.

It will take 5-10 days for the hair containing the metabolites to shoot out through the scalp, but what’s worrying is that they can remain there for years on end.

A hair drug test is usually viewed as the gold standard for all other types of tests because of its long detection window of 90 days or more.

How to Pass a Cocaine Urine Test in 24 Hours: Methods Overview

Although other types of tests, such as hair follicle tests, have higher detection levels, urine tests remain the most popular among most employers because it is cheap.

The cutoff level for cocaine is 300ng/ml for the immunoassay initial screening.

So you need to take the concentration level of the cocaine metabolites in your urine below the cutoff level.

How can you do that?

Here is the overview of each method. The detailed instructions I will provide later in this post.

Flushing – when you temporarily flush cocaine metabolites out of your bladder.

cocaine dilution

These methods use large amounts of water and diuretics to frequently urinate and flush the metabolites from the bladder.

The concentration of cocaine metabolites will reduce temporarily.

You will need to take vitamins and electrolytes to keep the color, creatinine levels, and specific gravity within the normal range.

Best for: People who don’t have much time before the test or people who will be supervised.

Read about flushing methods

Substituting urine sample – when you submit a clean urine sample instead of yours.

pass cocaine drug test with urine substitution

Substituting the sample with the synthetic urine or someone’s else urine, you will have a sample that is 100% clean from any metabolites.

This method requires additional devices like hand warmers to keep the sample temperature normal. And, probably, a whizzinator.

Also, this method is not legal.

Best for: People who have no other options for some reason. This method is not legal, and we don’t recommend it.

Adding something to the urine

adding adulterants to the urine

This method requires you to add adulterants(like zinc bleach, eye drops, vinegar) to the urine sample, so they will interfere with the test and produce a false negative.

This method worked 20-30 years ago, but modern drug tests can detect adulterants, and the lab will reject your sample.

Best for: no one. This method is not working anymore.


Flushing methods

Dilution + aspirin

The easiest and cheapest way of beating a drug test. It involves drinking a lot of water to take the concentration of cocaine metabolites in your urine below the detectable levels.

What’s so good about this method is that you can use it as a same-day solution.

However, this method is a complex process, and it is easy to fail.

You will need

Electrolyte powder or drink: This supplement consists of sodium and magnesium. It keeps your urine’s specific gravity level in check.

Creatine ethyl ester supplement: This helps raise the creatinine levels above the cutoff mark, especially if you are struggling with lower levels of this urine component.

Vitamin B supplement: This gives urine its natural color.

Aspirin: Its metabolites are known to cause false-negative results in the immunoassay tests.

  1. Take the 10 grams of creatine ethyl supplement 3 hours before the test.
  2. Take 200 milligrams of vitamin B 3 hours before the test.
  3. Drink 1000 milliliters of electrolyte solution every hour for three hours before the test.
  4. Take two aspirin tablets four to six hours before the test.
  5. Take a home urine test before you go to the test center.

Urine substitution methods

Synthetic Urine

macujo method

Synthetic urine is just as the name states. It is a fake pee that can substitute the real urine.

It smells the same, the color is the same, including the same ingredients such as creatinine, metabolites, uric acid, and urea.


Synthetic urine comes as a powder that you will have to turn into a mixture; here are the instructions.

The biggest challenge is getting it into the test center and into the bathroom, where you will take the test. Here are some suggestions.

Using someone else’s pee

macujo method

As disgusting as it sounds, one of the easiest ways to pass a urine drug test for cocaine is to use someone else’s.

The person you choose should be a non-drug taker, or it will defeat the purpose. You can use the male or female urine – the labs will not detect the difference.

Please note, this can be difficult to do if you need to pass a supervised test.


You need to collect clean urine in a squirty bottle to sound like you are peeing when you are in the toilet.

Since the urine has to be a specific temperature, you can’t do this the night before and carry it to the test center.

Ask your friend to come with you and get them to pee into the bottle just before you go in.

Keep the pee warm enough by resting it on the heating pad.

Put the bottle inside your underpants near your genital region. To use it, follow the same procedure as the synthetic urine.

You can collect and store your urine and use it on the day of the test. Here’s the guide on how to store it: How to store urine for a drug test.


If you are looking for a cheap way to pass and are ready for some difficulties – use the “dilution + aspirin” method.

If you are sure that you can keep the temperature of the fake urine within the normal range and the test is not observed – use synthetic urine.

If you need the urgent and hassle-free method – use the Fast Cocaine Detox Kit.

How to pass a hair test for cocaine

Hair tests have generally been rated as the hardest to beat whether you are being tested for cocaine or weed. This is because the drug metabolites are engrained almost permanently into particular hair strands, just like other hair components.

To cheat a hair test for cocaine, you’ll need to strip the cortex of as many benzoylecgonine metabolites as possible or to below 500 ng/ml, which is the cutoff level for a cocaine hair test.

There are 3 ways of doing this;

The First Method


This is a 7-step method that basically involves washing and rinsing your hair several times using an array of ingredients, including warm water, Heinz vinegar, Clean and Clear pink salicylic acid shampoo, and Aloe Vera shampoo (old style).

While this method continues to boast a solid record for success, there are stories of failure if it’s not carried out right away.

Another Method


The method works best if you have at least 10 days to the hair test because it involves 2 sessions of bleaching and dying that need to be spaced 10 days before the next session.

However, people with longer and thicker hair often need to bleach and dye the hair for a few more sessions, which again calls for more time.

Similar to the first method, this technique has a high success rate. But things can easily go south if the steps are not followed the latter.

How to Pass a Mouth Swab Test for Cocaine

A saliva test (a.k.a swab test) is the easiest test that you can take. It would be a very bad idea if you failed one, especially for cocaine known to disappear completely in 24 hours. But I don’t want to mean that there are no people who fail it.

Most laboratories use a cutoff level of 20ng/ml for saliva tests. So, to pass, you’d need to take the concentration of the metabolites in your saliva to below this level or make them hard to detect.

The easiest way to pass a saliva test for cocaine is by using water. This method basically involves rinsing your mouth with lots of water, and it helps lower the concentration of the drug metabolites to below the detectable levels.

You could also rinse your mouth using a mouthwash (Listerine is the most commonly used for this) or hydrogen peroxide. Learn everything you need to know how to pass a mouth swab drug test for cocaine in this article.

How long does cocaine stay in your system?

The length of time within which cocaine metabolites are detectable in the system varies from one person to the other, and it’s determined by several variables, including;

There is some good news, though. The detection window is generally so short compared to other drugs because, unlike weed, cocaine and its metabolites aren’t lipophilic (that is, they are not soluble in fat).

This means that they generally don’t linger around the body cells for so long after intake- and this is what makes it so easy to beat a cocaine drug test.

But then again, remember that the variables above contribute immensely to your odds of passing or failing the test.

How long do cocaine metabolites stay in urine?

No 2 cocaine users are the same, and, therefore, the length of time within which this drug is detectable in urine varies greatly between individuals.

Cocaine is metabolized pretty fast compared to its metabolites, and there is actually no exact window that can be used to detect in the urine. Very low concentrations are detectable during the first few hours, though.

On the other hand, benzoylecgonine – the major metabolite searched for in urine cocaine tests- is detectable in urine 2-4 days after occasional users’ last consumption. This detection window may stretch up to 14 days for habitual cocaine users.

How long is cocaine detectable in saliva?

As the liver continues to metabolize and detox cocaine from your body, a portion of the cocaine and its metabolites is expelled through the salivary glands.

Cocaine in saliva can be detected for 5-12 hours, while its metabolites, mainly benzoylecgonine, is persistently detectable in saliva for between 12 and 24 hours.

How long is cocaine detectable in hair?

Generally, a hair drug test is usually viewed as the gold standard for all other types of tests, credit to its long detection window of 90 days or more.

As you consume cocaine, traces of its metabolites are transported to the hair papilla through the blood system. They cross over into the matrix and eventually become a part of the hair core through follicular morphogenesis (growing hair).

It will take 5-10 days for the hair containing the metabolites to shoot out through the scalp, but what’s worrying is that they can remain there for years on end.

Not all hair strands have the metabolites, though. They will usually be found in random hairs and tiny parts. The only way of erasing them would be to shave the head bald and abstain from cocaine.

This method of cocaine detection isn’t so common for most employers due to the high cost involved. However, it’s the go-to drug test for occupations that require extremely high safety concerns, including oil and gas transportation.
