How to Dilute Urine for Drug Tests


Dilution is an effective way to beat a drug test after exposure to substances of abuse. Drink a detox drink or your own concoction of about 20 ounces of fluid, b-vitamins, one dose of creatine, and perhaps a zinc supplement to further lower the sensitivity of the test, one hour before the test. Pee a few times, then submit your specimen. If this is not possible, use Quick Fix synthetic urine or an adulterant like Klear or Whizzes.

What is a diluted urine sample?

Diluted meaning: In the lingo of the seedy world of beating drug tests, a diluted sample refers to two things:

  1. A sample flagged as dilute This is what you don’t want. This is when the technician tests your urine and the creatinine content, color, and electrolytes denote a diluted sample. This sample will either be seen as a test you must redo or a failed test if it is also positive for banned substances.
  2. A dilute sample which has successfully masked drug use. A satisfactory drug test.

You want to get the latter, rather than the former. But let’s examine what happens in each case.

A sample may be flagged as diluted if it has a creatinine content greater than 5 mg/dL or less than 20g/dL, along with a specific gravity lesser than 1.0010 or more than 1.0200. This can happen from adding water to the sample, or from drinking lots of water before the test, which can happen purposely or accidentally. If an employer gets a negative dilute test, he can order a second test or, he can just decide it’s a good result. Maybe he doesn’t want to pay for another test. If he orders a second test, if you know you’ve got drugs in the sample, you need to dilute again, but this time make sure the specific gravity and creatinine level is correct by taking a dose of creatine, b-vitamins, and adding a dash of salt to your drink. If you get a positive diluted sample, you’re out of a job.  A positive diluted urine drug test for probation could get you thrown up under the jail.  You want a negative sample that does not get flagged as dilute.

How much water to dilute urine for a drug test?

How to pass a urine drug test in 24 hours naturally

Dilution works just how it sounds. You dilute the urine. This is done by drinking extra water, not by adding water to the sample. Adding water to a sample will change the specific gravity and creatinine content and cause the sample to be flagged. Rather, you have to drink extra amounts of water, and also take diuretic substances. Here’s how step-by-step:
Drug test dilution success


Detox drink (20 ounces) or homemade concoction containing:

  • B-vitamins
  • Electrolytes (potassium, magnesium, sodium salts)
  • Creatine monohydrate
  • Diuretic herbs (burdock root, uva ursi)
  • Optional: zinc supplement

Our choice: Mega Clean Detoxify – 20 oz –  $ 69.95

Step by step guide

  1. Cease drug use as soon as you know you will need to take a test.
  2. On test day, an hour before your test, drink down the contents of your Mega Clean Detoxify bottle. If you are doing the homemade thing, just drink 20 ounces of an hour before test time. You will need to add lite salt (a pinch per drink), creatine (5 grams), b-vitamins, or any multivitamin, or a big piece of steak. You will need a diuretic so drink coffee or tea. You will be peeing a lot. Make sure your test pee is a third or fourth pee after taking your dilution substances. A premade detox drink will already contain everything you need, so the extra supplements will be unnecessary if you go that route.
  3. Go to the test and pee. Do not add anything to the urine sample.
  4. You should test clean. The drug metabolites are diluted down such that they are undetectable.

How to Beat a Drug Test, According to Experts and medical scientists

Abstaining: passing a drug test naturally

In this case, you’re not giving a fake urine drug test. You are actually allowing the drugs to get out of your system. This will work for saliva, blood, and urine drug tests. Unfortunately, it will not work for hair follicle tests which will require you to abstain from drugs a full 90 days.

Here’s how long you will have to abstain:

Most hard drugs are out of your system from days to a week. Weed can stay in your system for up to 30 days. And all drugs can be detectable in hair for up to 90 days, as they only test the 1.5 inches of hair closest to the scalp. Hair grows 0.5 inches per month, therefore, the 1.5 inches of growth covers a period of 90 days in which drug metabolites are deposited in and detectable in the hair follicle. Detection also depends on the extent of drug use, with heavier use being detectable for a longer period of time.

Best way to pass a drug test on short notice

Diluted pee

Dilution is shown to work anecdotally and in pre-scientific studies done by Vice entertainment. They simply used some detox products which work by dilution, and then drug tested themselves. They discovered, indeed, if you follow the basic instructions, drug metabolites are not detectable and the sample has the color, smell, and creatinine content of undiluted urine. In other words, a satisfactory test.

Dilution is one of the safest ways to pass a drug test because if the sample comes back negative but diluted, the employer scientifically has no grounds with which to claim that you intentionally diluted the sample as simply drinking a lot of water or even the soda they tell you to drink before the test can cause a sample to be diluted. In order to pee on-demand as you have to do for a drug test, you must usually intentionally drink more fluid than you would normally drink, and that can naturally lead to a dilute sample. However, if you get a dilute positive result, it will look like you both took drugs and tried to hide it, but still, they can’t prove later and you cannot, therefore, be charged with fraud. Cheating a government drug test, if proven, can land you in federal prison for trying to defraud the government of the United States. This does not happen with regular consumers for the most part but can happen with company owners who sell detox products.

How to add color to urine for drug test

The basic way to do dilution is to drink 20 ounces of water, an hour before the test, and a booster of 10 to 20 ounces just before the test. You need to add lite salt, b-vitamins, and a normal dose of creatine to the first drink. The b-vitamins will add the color back to your urine. The salt will prevent water intoxication and the creatine will raise creatinine levels, which is used to detect dilution.

Synthetic Urine

You can buy synthetic urine which will pass a drug test. The most popular synthetic urine on the market is Quick Fix urine. It has all the correct parameters of human urine. It will cost you about $ 29.95. It will pass most drug tests. However, test makers are playing a cat and mouse game with synthetic urine makers so one can never be sure when they will figure out how to detect the current crop of synthetic urine products. For this reason, Quick Fix labels the version of their product with numbers, the latest version (as of September 2019) is Quick Fix 6.2.


Many adulterants used to beat drug tests have been recognized in scientific publications. Klear, Whizzes, Urine Luck, and Stealth are some products that are recognized as able to foil drug tests (Fu) (Advances in Clinical Chemistry 2016). These products actually work but drug testers are coming up with ways to detect them. Common adulterants like bleach are easily detected. However, oxidizing agents actually destroy the drugs, so even if the agent is detected, it cannot be proven which drugs were in the sample. If using an adulterant, check your local laws to be sure you are not in danger of being charged with fraud.

Another way to adulterate a sample, which cannot be detected as of today, is to take a zinc supplement. Once the zinc is in the urine, it will decrease the sensitivity of the test. In the Journal of Analytical Toxicology, zinc was found to reduce the detection of cocaine and methamphetamine (Venkatratnam and Lents). Adulterants like aspirin are now detectable and will no longer fool a drug test. Instead, take a zinc supplement.


Dilution is an effective way to beat a drug test. Timing is key. Make sure you’ve peed a few times before you submit your testing sample. You want your pee to be watered down but contain the b-vitamins and creatinine to make sure dilution is not detected.
