Smart Ways To Flush Cocaine Out Of Your System Fast and Pass a Drug Test

Last Updated on

There are a whole lot of ways that have been suggested on how to pass a drug test for cocaine. A few of them do work, but most of them don’t.

Of course, the chances are that you are desperate for methods that work- and that’s what I have majored in on this article.

What You Will Learn

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 are 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 detectable 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 credit to its long detection window of 90 days or more.

How to Pass a Urine Test for Cocaine

Although other types of tests such as hair follicle drug tests have higher detection levels, urine tests remain to be the most popular among most employers due to the fact that it is cheap.

The cutoff level for cocaine is 300ng/ml for the immunoassay (initial screening) drug test.

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

How can you do that?

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

These methods use large amounts of water and diuretics to make you urinate frequently and thus 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 drug test, who have to pass a supervised drug test

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

cocaine 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 drug test and produce the 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 in a bid 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 drug tests (link here).

  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.

  5. Chew the QClean tablet with 32 ounces of water. Wait an additional hour, and be sure to urinate several times before going to your test.


Urine substitution methods

Synthetic Urine

Synthetic urine is just as the name states, its fake pee that people can use to pass a drug test.

It smells the same, the color is the same, and it includes 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

As disgusting as it sounds, one of the easiest ways to pass a urine drug test 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 so that it sounds 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 you 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 components of the hair.

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 cocaine hair test.

There are 3 ways of doing this;

The Macujo 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 very strong record for success, there are stories of failure if it’s not carried out right away. I have already written an in-depth guide on how to pass a hair drug test using the Macujo method.

The Jerry G Method

macujo method

This method of passing a hair drug test was named after its ‘inventor’- Jerry G who created it in 2008 and it’s much cheaper than the Macujo.

The Jerry G 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 between 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 Macujo method, this technique has a high success rate. But things can easily go south if the steps are not followed to the latter.

Zydot Ultra Clean Detox Shampoo

This is our #1 recommended solution for passing a hair follicle drug test the same day.

There are several reasons why this shampoo has received such a high rating and many positive reviews from people who’ve used it and continue to use it today. It all boils down to its new and improved formula.

The Zydot Detox Shampoo has been formulated to be a 3-in-1 internal hair purification treatment that combines the functionality of a shampoo, purifier, and conditioner in one affordable box.

The shampoo compositions of this treatment work by stripping off medications and chemical buildup from day-to-day hair spray and styling and finishing products on the hair shaft.

This makes it easy for the Purifying ingredients to penetrate the strand into the inner structure.

The purifying component releases dissolve and remove impurities from chemical hair products and medications that have been entrapped within the hair.

The last component of this shampoo employs the power of Aloe Vera to condition your hair by making it easy to control tangles and also adds sheen.

Other than the positive feedback that this product has received from its past users and the fact that it works as a same-day solution, there are 3 reasons why you might want to try it out.

  • First, it’s undetectable by the hair drug tests and won’t cause inconclusive results.
  • Secondly, it’s made of safe ingredients that won’t damage your hair and it’s completely legal.
  • Third, it is backed by a 100% money-back guarantee although you won’t need to use it.

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 that is 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 in lowering 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.

I have not drank beer or anything, but I have had coffee 4 times this week with 4 Splenda’s, and also a lot of sugars (I.e. donuts, Splenda in my coffe, chocolate), Also have been doing little bumps all week. And bring up the caffeine, because when I was reading on some websites it said to stay away from caffeine, it can hold it in your system also.

    Cocaine is a hell of a drug.
    Keep a clean spirit and your chin high, and believe that with the power of sobriety all these problems will cease to exist.
    I was a terrible user and had frequent tests, I always use a strip pill but learned also that lots of water and a clean mind go a long way.
    Stay positive everyone.

      Hi. The cocaine is detectable in the urine for up to 4 days for occasional users. So It’s not a good idea if you have a drug test on Monday

  8. Anonymous says:

    I’ll simplify it 6 year lab test .24 hours is all u need In those 24 hours straight water followed by strong multivitamins (why) it turns your urine yellow .The more days you have the better standing ull be at.This just phase 1.You can pee in the cup by water loading first meaning drink alot of water till u start avoiding clear once u see that that’s an indicator your only pissing water..Once you notice that keep drinking water no matter what u do but once discover clear take multivitamins but potent vitamins .Once you see your urine go from clear to vitamin yellow your ready to be tested .The more multivitamins u have in ur pee it will rendering any trace as ur clear pee indicates your watered down .Take the multivitamins and continue to piss vitamin water.Thats how u keep it from looking like it’s just water.When u give the sample it will be water mixed with everything you see on that label of multivitamins is what your gone give the lab.#1 ur gone pass with flying colors or#2 it’s gone come back negative dilute means ur negative but ur sample is watered down.Guys that’s a no fail wether u just bought another day for a retest or another void then same result again lmao.The object is dont show what your really pissing to fail Over 6 years I been experimenting Same method most complete pass and some come back negative dilute.Recently I discover how to rid the negative dilute. U have to modify what I just told u Only modification if you wont 1 test sure pass grab a bottle off a good donor urine add it to the cup dont worry temp of the donor piss because your gone bring your donor urine back to life when u pee your vitamin water in the mix of donor urine .That will bring the temp and everything up lmao this what I call the clean mix down .When they ask me to fill the cup to a certain line I fill her up to the rim to be a jack ass because i already know what’s in my cup .Either bright yellow vitamin water or my favorite the mix down lmao depends on the skem I chose. The whole point stay vitmined up and watered up idc what he or she say you wont to give that to them not your hott piss.Far as multivitamins you dont know how many to take lmao follow the instructions on the bottle on how many you can consume. Mines right now 2 capsules twice a day.Stay on your vitamin game and water no matter what Its up to you to modify the vitman water skem I just learned it easier to get that 1 hit wonder when u modify it

  12. Roc says:

    Oh yea to add buy a handful of testing strips to see where ur vitman water stands it’s coming back negative then stay on ur game intill u know ur results I test myself always before giving is how I factor my pass rate again it’s been 6 years it’s been the water and multivitamin skem .Aslong as ur getting back negative dilute sample ur not failing it they’ll ask for a retest hell I’d give them the same skem and when I do I’m hired but the vitman mix down is easier because you dont have to keep up with temp just add on top of mix down that defeats the right temp ordeal and a bonus the extra million more vitmans you just added lmao

  13. Jen says:
