The apple cider vinegar detox method

People who trust apple cider vinegar to mask their drug use believe that it works because it cleans urine of any traces of drug metabolites. Cleaner urine means that you have a better chance of a negative drug test result.

The most popular ACV detox method assumes that you can use it on the same day as the drug test. People like it because they can use this method to pass a drug test on short notice.

Here is what you should do:

  1. Add 2 tablespoons of ACV to a glass of water. Mix and drink it.
  2. Drink at least a gallon of water throughout the day before the test.
  3. Urinate as often as possible to remove the contaminated urine from your system.

The method seems practical because apple cider vinegar is available in most homes and grocery stores. It is also very cost-effective, and it doesn’t matter what brand of ACV you choose to use.

The science behind this method

The claim is that an apple cider vinegar drink cleanses THC from your body because it creates an acidic medium. What does this mean? Your body excretes at least 15-20% of the THC in the form of the acidic urinary metabolite (11-Nor-9-carboxy-Δ⁹-tetrahydrocannabinol), which means that you need an acid environment to get rid of these unwanted substances. ACV helps to create such environment.

Will apple cider vinegar really help you pass a urine drug test?

No, there isn’t any scientific evidence to prove that it works, although this method has a lot of positive reviews on the internet. It’s more likely that the drug metabolites are diluted by the massive amounts of water you drink. It’s not the vinegar but the water that cleanses your system and hides traces of the drug in your system.

Diluting the drug metabolites with water doesn’t always work as you want it to, because it affects your urine pH, density, and creatinine levels. Too much diluting may cause your urine specimen to be rejected.

Adding apple cider vinegar to urine sample

Adding apple cider vinegar directly to a urine sample is the second way people believe it can help them pass a urine drug test. Since pH of vinegar is 4.3, it  lowers the pH level of urine, which is normally between 6.5 and 7.2. It is believed that the slightly acidic nature of the altered urine masks drug metabolites.

Studies prove this method. For example, 1988 study conducted in University of Utah showed us that several adulterants may cause a false-negative result in urine test. The adulterants tested included vinegar, and the study results clearly showed that this substance may invalidate enzyme immunoassay used for detecting drug metabolites.

The problem of this method is that lab technicians always check the pH level of the sample. Vinegar can lower the pH of your urine so much that it goes beyond the physiologically possible range. This is a red flag for technicians who are watching for urine adulteration.

Adding apple cider vinegar directly to a urine specimen is a risky and unreliable technique. If a lab technician believes you’re trying to cheat the test, he or she will reject your specimen and force you to provide a new sample under stricter, supervised conditions.

Using apple cider vinegar to pass a hair drug test

Some people also use apple cider vinegar to pass a hair drug test. These people believe that acidic substances, such as vinegar, can remove toxins from the hair.

The method is simple:

  1. Apply vinegar to your hair, especially the back area where sample collectors usually take a sample.
  2. Wait 15 minutes and apply salicylic acid.
  3. 30 minutes later use liquid detergent and wash your hair thoroughly.

Although this method of passing a hair drug test is very popular among the drug users, it does not have any reliable scientific evidence. You also need to keep in mind that ACV is just a part of this formula, and the salicylic acid as well as liquid detergent also play important role. When used together, they may give some result, but apple cider vinegar on its own cannot help you pass a hair test.

Will apple cider vinegar help you pass a mouth swab test?

No, vinegar itself cannot help you pass a mouth swab test. This method calls for a mouthwash made by adding a tablespoon of apple cider vinegar to a glass of water. The rinse is supposed to help you produce more saliva, which must dilute the drug concentration in an oral fluid sample.

There is no evidence to support the fact that vinegar can help you pass a mouth swab test this way. Rinsing your mouth with ACV is recommended only as a preparation before using more effective solution.

If you’re serious about passing your saliva test, then you should only trust a method that has been proven. Use a saliva detox mouthwash designed to get traces of drugs out of your oral fluids.


Apple cider vinegar is not a reliable solution for masking drug use regardless of the type of drug test. In addition, drinking or gargling it is very unpleasant, and not many people can actually force themselves to put the vile substance in their mouths. If you do manage to swallow it, then you have to watch out for its known side effects like vomiting, indigestion, nausea, and diarrhea.

There are much more reliable ways to detox your body before a drug test. Choose a product that has your best interest at heart and is proven to help you pass the test.
