Does Drinking Water Help Get Weed Out Of Your System

Drinking a lot of fluids before a drug test has, time and again, proven to be effective and reliable. So effective it is that if you have checked out other methods of detoxification, you may have noticed that some are built on the same concept.

As simple as it may sound, some people fail drug tests after diluting their urine with water. One may wonder how that is possible seeing as it only involves drinking excessive amounts of water and peeing a lot.

It is that same mindset that has made people fail the tests and consequently, lose their jobs.
The instructions on how to go about it are all over the place. Some leave out vital pieces, while others give inaccurate information. For instance, they mostly do not put body weight and BMI into consideration when recommending the amount of water to drink.

This guide brings these, and other, truths to light for you to successfully beat the drug test. But to do this, you need to know what the drug test are looking for and the reasons why diluting your sample may not work.

What they are looking for

There are two types of urine drug screenings that are mostly used: Immunoassays, and GC/MS. These tests do not look for the drugs themselves; they look at how the metabolites of the drug react with the immune system, and its capacity to form antibody-antigen complexes.

The results of the test are expressed in ng/ml (nanograms per milliliter). Although many immunoassay tests give instant results regarding positive and negative, they generally use a cutoff point to determine whether one has passed or failed.

A positive on the immunoassay tests may, in some cases, need a follow-up. This is where the more rigorous GC/MS test comes into play. It is less possible to get a false positive on this test.

If the outcome of the immunoassay test is above 50ng/ml, or that of the GC/MS test is above 15ng/ml, you have failed the test.

When you drink plenty of water, you increase the frequency of passing out urine. Many sites lead people to believe that it increases the excretion of THC metabolites and other toxins, which is not true. The only effect it has is to reduce their concentration past the cutoff point, increasing your chances of beating the test.

Why you may fail

There are two known ways by which you can dilute your urine: externally and internally. External dilution doesn’t have a large following to back it up. The only possible reason to fall back on it as a final resort is if the drug test was spontaneous and you did not have time to prepare.

The process involved in external dilution is as simple as adding some water to the sample before handing it in. First, the only way you would manage to add water to the sample is if the test is not regulated by federal guidelines. These guidelines specifically state that all the water supply in the collection site should be turned off to prevent cheating.

If in the rare chance you manage to add some water into the sample, a simple temperature test will show that your urine is below the normal temperature.

Internal dilution is effective when all the steps and instructions are followed to the latter. The biggest hurdle to internal dilution is the integrity test. If you manage to work your way around it, well then, home run for you.

But how are they able to tell that the urine is diluted?

Integrity test

There are a couple of things which, if checked, could reveal that your sample is diluted.


Colorless urine is an indication of dishonesty. The visual appearance of your urine is enough to ask for another sample under supervision.

Creatinine levels

Creatinine comes from creatine and is a by-product of muscle metabolism. It is excreted during urination and used by drug testing companies to determine whether the urine has been diluted.

The normal creatinine levels in the urine are usually between 20ng/dl to 30ng/dl. If the levels are below 20, then the sample is termed as dilute.

Specific gravity

Specific gravity, in simple terms, is the density of your urine. This is determined by the percentage of solutes in the sample. The sample will be dismissed as dilute if the specific gravity is 1.003 or less.

If you don’t manage to pass the integrity test, there are two reports that you can expect: a positive, or a negative dilute. A positive dilute is arrived at when the sample, though lacking in either of the three things discussed above, has metabolites that exceed the cutoff point.

It is treated as a normal positive.

A dilute negative means you succeeded in masking the results but failed in keeping either of the three things above in check. The employer may choose to fire you for dishonesty or ask you for a cleaner sample.
So, how do you keep everything in range for the integrity test and maintain the metabolite levels below the cutoff?

Working your way around it

The only way you can make sure that everything works out is through thorough preparation. To set things straight, dilution is not simple, and you will be very mistaken to think so. The method that you are about to read is, unlike what most guides deliver, detailed in that it looks at all the aspects of a successful dilution.

There are a couple of things that you will need for this procedure: THC and creatinine test strips, vitamin B2, and electrolyte powder. You may also include an optional creatine supplement if you are worried about cutting it close.

The first step before rushing to gorging yourself with gallons of water is to find out whether you need a new hydration rate.

To do this, you will need first to calculate your lean body mass. For every pound of LBM, you will need 4 mL of the electrolyte solution per hour for three hours. Try to drink it evenly, and if the need arises, it is okay to pee. After the three hours, measure the THC metabolite, creatinine and specific gravity levels in your urine.

The rules that guide the determination of a new hydration rate are as follows:

  1. If the metabolite levels are under 50ng/ml and creatinine levels above 20mg/dL, you are safe.
  2. If the metabolite levels are above 50ng/ml and creatinine levels above 20mg/dL, you need to dilute the urine a little bit more by increasing the rate of hydration.
  3. If the metabolite levels are under 50ng/ml, and creatinine levels below 20mg/dL, you need to increase the hydration rate.
  4. Repeat the self-test using the new hydration rate.
  5. If the metabolite levels are above 50ng/ml, and creatinine levels below 20mg/dL, increasing hydration rate alone puts you at risk of making your sample dilute. If this is your case, consider taking some creatinine supplements.

The creatinine supplementation should be taken starting from 5 days to the test. The recommended daily intake is 20 g per day.

On the test day, using the hydration rate you had determined during the test run, start taking the electrolyte solution 3 hours to the test. 200mg of the vitamin B2 specified above should be taken an hour to the test to add color to the urine.

If you follow this guide to the letter, you are guaranteed of beating every drug test you come across.
