How to pass a urine test for cocaine

There are a number of ways to pass a drug test for cocaine. This includes the following:

Toxin Rid 

Toxin Rid is a detoxifying product that can help get rid of substance presence while you are also abstaining from cocaine use. This product contains herbs such as alfalfa and kelp. These two ingredients have the capacity to increase detoxify heavy metals and urine output.

Toxin Rid comes in formulas starting 1 day to 10 days. The latter formulation will allow you to abstain from the use of substance for 10 days, allowing you to handle withdrawal symptoms. This is done by keeping your water and electrolytes balanced, while preventing irritability and dehydration. 


For people who ask about how to pass a drug test for cocaine, dilution seems to be the best way available. The concept of this procedure is quite easy. All you need to do is to take more water, as this will dilute the urine, allowing cocaine metabolite level to become lower than water. 

A couple of hours before taking a drug test for cocaine, you can drink up to 32 oz of green tea filled with electrolytes. This can be done by adding a pinch of baking soda and salt, or commercial electrolyte products such as Gatorade. Green tea can act as a diuretic, as it has caffeine content, thus increasing urine output. You can also take creatine monohydrate (5g) and Vitamin B pill. 

Home Remedies

There are also some natural methods that you may want to try at home. Try the following:

Exercise and sweating

Exercise and sweating can help in flushing out cocaine from your body. However, note that with exercise alone, you may not be able to completely get rid of metabolites needed to pass the test. Still, exercise and sweating can help burn fat cells that will remove substances. 

Exercise as a way to help pass a drug test should be done at least a month before a cocaine test. It should also stop about two weeks prior to the test. Why? Exercise may result to the substances breaking into the bloodstream, directing to the urine, thus making it hard for you to pass the urine test

Another possible related option is sauna. This is a tested way to start sweating. Avoid overdoing it though as it may cause a heat illness. 

Baking Soda

Baking soda has different uses aside from the ones we are already familiar with. It can also help you pass a cocaine test. It can help in interfering with the detection of substances such as methamphetamine. Since baking soda is alkaline, it helps prevents your kidneys from producing methamphetamine for a time. 

If you are about to take a cocaine test, you can consume 1 or 2 tablespoons of baking soda a couple of hours prior your test, along with 32 oz of water. Going over this measurement may no longer be tolerable, and could even result to alkalosis, which is an imbalance of electrolyte, and stomach rupture. 

Using baking soda as an antacid is also a good option. Users who found this effective take one teaspoon of baking soda with 16 oz of water 2 hours prior the test. You can then add 16 oz of green tea, b-vitamin pill, and creatine (5g). 


Taking a standard dosage of zinc pill 2 hours prior a test helps in decreasing the possibility of being detected with substances like cocaine. This is safer compared to niacin and aspirin which were used in the past. Too much use of aspirin may result to stomach bleeding, which is why it is best to avoid this route and use a safer alternative – zinc. 

Cocaine presence in the body

While cocaine is known to metabolize in the body for around four hours, a drug test for cocaine can detect this substance in urine for about 2 to 5 days, saliva for around 2 hours, while traces may still be found up to 19 hours. It stays longer in the hair, as it can remain for until 90 days. 

This may differ for heavy or long-term users, as the substance can remain in the body for a longer period of time. In some specific drug screening methods, such as the hair follicle drug test, cocaine may even be detected after three months. 

There are some factors which may affect the length of time in which this substance stays in the body. This includes the amount of cocaine used, whether it is concentrated or mixed with other types of substances, and the method of test that they have to take. 

The more frequent a person uses cocaine, the more challenging it will be for the body to remove it since the elimination systems of the body decreases efficiency and functionality along with frequency of use. The drug’s concentration should also be considered. If the cocaine is pure, the potency is higher, which means that the effects will be stronger, and it will stay longer in the body.

Cocaine screening tests

A drug test for cocaine often comes in the form of blood, urine, saliva or hair test. These tests are effective in showing whether cocaine, as well as the metabolites are found in the body. These metabolites refer to chemicals that are naturally created by the body as response to cocaine processing.

They come in the form of ecgonine methyl ester and benzoylecgonine. The same test is also used to screen other substances such as marijuana, opioids, PCP and amphetamines. 

These tests may be performed in a clinic or a doctor’s office. The results may be available in just a few minutes after a rapid screening. Even though saliva and urine tests are acknowledged as more common, hair may also be used. In fact, it is regarded as effective since it can detect the presence of cocaine for several months after the last dose, though the process may not be consistently accurate.


While it may be challenging, there are a number of possible ways on how to pass a drug test for cocaine. Abstinence may be the best choice, but if you are out of time, you may want to try some of the methods mentioned above.

As a back up plan, you may get some synthetic urine that contain qualities of real urine. Make sure that what you are getting contain creatinine, albumin, urea, potassium chloride, uric acid, water and phosphate.
