Fastest ways to get cocaine out of your system and pass a drug test

In this post, we’ll give your the step by step instructions on how to clean your system from cocaine and pass urine, saliva and hair drug test.

But some important points first:

How long does it take to get cocaine out of your system?

Also, hair drug tests can detect cocaine residues for up to 90 days!

How to Pass a Urine Drug Test for Cocaine

The cutoff value for cocaine is 300ng/ml for an immunoassay test. These are the preferred initial screening drug tests commonly ordered for detecting cocaine metabolites.

This means that if the concentration of benzoylecgonine, one of the main metabolites of cocaine, is below that level, hurray, you will pass!

It’s simple! All you have to do is lower the concentration of benzoylecgonine below the cut-off level.

Want to know how? Well, I’ll give you three options, but first, bear in mind that certain factors will directly influence these methods. These are:

Before we proceed, here’s the guaranteed way to pass the test:

Fast Cocaine Detox Kit

fast cocaine detox kit

This kit already has all the required ingredients in the right proportions to pass the test with flying colors.

It starts to work in just 90 minutes and gives you a 5-hour window to pass the test.

This kit is legal and not detectable by the labs.

So, let’s look at other options


If performed correctly, flushing is an extremely easy and legal method that promises you’ll pass your cocaine drug test.

And the best part – this method guarantees success even when you have a limited time; like even if your test is on the same day, you can start using this method!

As the name suggests, all you need to do is drink plenty of water before your drug test.

This will literally ‘flush out’ cocaine metabolites of your bladder, temporarily reducing their concentration in the urine below the drug test’s detectable level.


Here’s what you’ll need for the flushing method, and why.

Water Obviously!
Vitamin B Supplement This restores urine’s natural color. Without this, the sample might seem suspiciously clear instead of the natural yellow.
Creatine ethyl ester Supplement It restores normal creatinine levels in the urine, which can become questionably low after consuming too much water.
Electrolyte Powder or Drinks These contain sodium and magnesium, which help keep the urine’s specific gravity level in check and make it seem ‘normal.

Step by step instructions

Natural Detoxification

If your drug test is in about 2 months, you can wait for your body to detox itself. And since this is a natural process, it’s guaranteed to work.

Simply put, detoxing naturally from cocaine allows nature to take its course – your body rids its self of all traces of the drug and allows itself to return to its regular health.

By following a healthy diet and exercise plan, your body will detox from cocaine naturally, and the concentration of benzoylecgonine will fall below the detectable level.

Here’s how you can help your body naturally detox.

Follow a Healthy Diet Plan Avoid fast foods and sugary products which contain preservatives, flavor enhancers, and coloring agents. Eat more green vegetables and fruits to increase the amount of fiber in your diet which helps bind and remove metabolites from your system.
Drink More Water This will help flush out more toxins from your system; drink approximately 8-10 glasses or 70 oz every day.
Exercise This will help the body remove toxins quickly and will also keep you fit. Do some low-intensity cardio, like 30-60 minutes of running.
Avoid Alcohol Alcohol, mixed with cocaine, makes it harder for the drug to leave the body.
Avoid Caffeine Also makes it harder for the drug to leave the system.

Urine Substitution

Urine substitution means that you:

For urine substitution methods to work, you’ll need to keep its temperature between 90 °F–100 °F. And if you’re being observed during the drug test, you’ll need to use a whizzinator or some related device to bluff the observer.

But be warned: we do not recommend this method AT ALL.

First off, it is illegal.

And besides, it is extremely risky and difficult to correctly implement without being caught at some point.

If you try to deceive the system and get caught, it could have seriously disastrous consequences for your professional and personal life.

And even if you think you’re a genius mastermind, neither of the options mentioned above for urine substitution guarantees that a proficient lab won’t be able to identify that the urine sample was manipulated.

So why risk humiliation when healthier and more reliable alternates exist?

How to Pass a Hair Drug Test for Cocaine

As mentioned earlier, a hair drug test can detect cocaine metabolites for up to 90 days.

Cocaine metabolites are stored inside the hair shaft, so you’ll need to remove them from the shaft to pass the test.

There are 3 options:

ZYDOT Ultra Clean Shampoo

Zydot Ultra Clean Shampoo is the most popular solution to pass a hair drug test. The manufacturers are so confident about their product that they offer a full money-back guarantee if it doesn’t work. You can use shampoo to eliminate any drug from your hair follicles.

The good news is that you can use it on the morning of your drug test, and it will still do the trick.

Remove All Hair from the Head And Body

You might be laughing now, and rightly so!

Shaving your entire body might be physically possible, but I’m sure a bald and hairless individual coming in for a cocaine drug test will raise a lot of eyebrows and questions.

The Macujo Method

Here’s a method considered to be among the most successful ways of passing a hair drug test – the Macujo method.

And it’s extremely suitable for chronic users who want fast and effective results.

The science behind this method is simple – drug metabolites travel to and are deposited in hair follicles. The Macujo method opens the cuticles of the hair and flushes them out from the hair cortex within the follicle.

Here’s what you’ll need:

  • Heinz Vinegar
  • Clean & Clear Shampoo (particularly one that contains salicylic acid)
These two help open hair cuticles by creating cracks and splits. The shampoo also gives an in-depth cleanse by eliminating barriers such as oil and dirt.
  • Aloe Rid Shampoo
  • Tide Laundry Detergent
Combined action to fully break down hair follicles and completely flush out toxins.

Instructions (make sure you follow every last detail):

Now before beginning, you must stop using any drugs, otherwise, you won’t get expected results.

Tip: You may need to repeat this process a few times to effectively flushing all drug residues out of the hair follicles.

How to Pass a Saliva Drug Test for Cocaine with Listerine

This might seem too far-fetched, but many people have passed cocaine drug tests using Listerine strips, and science also proves that it works well.

However, it is not clearly understood how brushing the mouth with Listerine, or even swallowing it, helps pass a drug test. The main belief is that it uses its bacteria-killing ability to destroy drug metabolites.

What’s best is that the components of Listerine are not detected in the tests, so it’s a win-win situation.

Here is the most common approach. You’ll need:


Preparing for the Test

  1. It’s best to avoid using weed or any other drugs for at least 2-3 days before the test.
  2. A major aspect here is to increase and retain the water content in your mouth. One sure method of doing this is to keep eating and drinking. Avoid foods that dry the month (nuts, dry crackers, popcorn, and sugary foods), and consume foods that increase saliva production, like apples, cucumbers, pasta, cheese, and spicy foods.
  3. Thoroughly brush your teeth, tongue, and gum, preferably 3-4 times each day, for at least 3-4 minutes. Make sure that you carefully scrub the teeth, tongue, and the top, bottom, and sides of the mouth. You could also use Listerine here, or dental floss.

Day of Test

  1. Increase brushing time to at least 15 or 20 minutes.
  2. Use Listerine at least four times, or as many times as you can before leaving your house. Let the mouthwash stay in your mouth for at least a minute before spitting it out. Yes, Listerine stings, but keep your eyes on the bigger prize!
  3. On the way to the test center, scrub 2 Listerine strips into each cheek and allow them to dissolve. Dissolve another pair of strips under the tongue. This ensures that any molecules that might have escaped all the brushing and rinsing are cleaned.

Before Test

  1. At least 30 minutes before the test, rinse your mouth with Listerine one last time, and then rinse with water.
  2. Rub 2 more strips inside the cheeks one last time before meeting the lab technician.

No matter what method you choose, remember to follow all steps carefully; you don’t want to fail and feel miserable just because of a small mistake!
