Kombucha and Drug Testing: What You Need to Know

Kombucha, a popular fermented tea beverage, is praised for its potential health benefits. However, it has raised some concerns regarding its effects on drug tests. This article will explore the relationship between Kombucha consumption and drug testing, providing insight into how to avoid potential issues and the implications for future research.

Quick Answer:

While the likelihood is minimal, there is a small chance that drinking large amounts of Kombucha could cause a positive result on a drug test due to the presence of trace amounts of alcohol and other compounds.

Understanding Drug Testing

Drug testing is a method used to detect illegal drugs or medications in an individual’s system. Biological samples such as saliva, urine, blood, or hair are collected and analyzed for the presence of drugs and their by-products. Employers and sports clubs often implement drug testing to ensure compliance with laws and maintain a drug-free environment.

The Role of Kombucha in Drug Testing

Kombucha is a fermented tea that naturally contains small amounts of alcohol. If left to ferment for too long, its alcohol content may increase. While standard drug tests typically do not screen for alcohol, excessive Kombucha consumption prior to testing can sometimes lead to false-positive results.

To avoid potential issues with drug testing due to Kombucha consumption, it is advisable to either abstain from drinking it or limit your intake before the test. Inform the testing personnel about any supplements or beverages you have consumed beforehand. When in doubt, stick to water to ensure a smooth drug testing process.

The Science Behind Kombucha

Kombucha beverages are created through the fermentation of tea, sugar, and a symbiotic culture of bacteria and yeast (SCOBY). Although the beverage is generally considered safe, there have been concerns about the potential impact of Kombucha on drug test results.

The following table summarizes the possible false positive results that could occur in various drug test types due to Kombucha contaminants:

Factors to Consider

Kombucha’s fermentation process generates trace amounts of ethanol, which can be detected in drug tests. However, the ethanol levels in Kombucha are generally low enough to avoid triggering false positive results. It is important to note that consuming large quantities of Kombucha or drinking from an unregulated source may increase the risk of a positive drug test result.

Precautions and Suggestions

To minimize the risk of a false positive result in drug testing, consider the following suggestions:

  • Refrain from consuming Kombucha for at least two to three days before the test.
  • Purchase Kombucha from reputable sources and check the beverage’s alcohol content before consuming it.
  • Implement these measures to reduce the likelihood of a positive drug test result and ensure accurate testing outcomes.

Can Kombucha Cause a Positive Drug Test Result?

While trace amounts of alcohol and other substances in Kombucha may lead to a false positive result, the probability is low. However, it is essential to be cautious about the amount of Kombucha consumed before a drug test. The fermentation process produces ethanol, which can elevate blood alcohol levels and potentially lead to false positives for substances like THC.

Although testing positive for drugs due to Kombucha is uncommon, it cannot be completely ruled out. Exercise caution and limit your Kombucha intake before any drug tests.

The US Anti-Doping Agency (USADA) warns athletes that consuming mislabeled or contaminated supplements or beverages containing prohibited substances can result in doping violations, even if unintentional.

Studies and Research on Kombucha and Drug Testing

Various studies and research have investigated the potential effects of Kombucha

on drug testing. Most of these studies have found that Kombucha is unlikely to cause a positive drug test result, given its low alcohol content. However, the possibility of false positives cannot be entirely dismissed.

The Importance of Further Research

While existing research indicates a low likelihood of Kombucha causing a positive drug test result, further studies are necessary to confirm these findings. As Kombucha becomes increasingly popular, it is crucial to understand its potential impact on drug testing procedures fully.

Kombucha Consumption: Weighing the Benefits and Risks

Kombucha is lauded for its potential health benefits, including improved digestion, detoxification, and a stronger immune system. However, individuals should be aware of the potential risks associated with excessive Kombucha consumption, especially before drug testing.

Balancing Kombucha Consumption with Drug Testing Concerns

To enjoy the health benefits of Kombucha without jeopardizing drug test results, consider the following:

  1. Monitor your intake: Keep track of your Kombucha consumption and avoid excessive intake, especially before a drug test.
  2. Know the alcohol content: Always verify the alcohol content of the Kombucha you consume, as levels can vary between brands and production methods.
  3. Choose reputable sources: Purchase Kombucha from trusted suppliers to ensure you’re consuming a quality product with accurate labeling.

By following these guidelines, you can enjoy the benefits of Kombucha without worrying about its potential impact on drug tests.


What should I do if I have to take a drug test but regularly drink Kombucha?

If you know that you will be taking a drug test soon, it is best to abstain from drinking Kombucha or limit your intake to small amounts. If you are concerned about a false positive, you may want to inform the tester that you drink Kombucha regularly.

How much Kombucha would I have to drink to fail a drug test?

It is difficult to determine precisely how much Kombucha you would need to drink to test positive on a drug test, as it depends on various factors, including the strength of the brew and your individual metabolism. However, it is unlikely that you would test positive from drinking a typical serving or two of Kombucha.

Is there a way to remove the traces of Kombucha from my system before a drug test?

There is no guaranteed way to remove Kombucha from your system before a drug test. The best approach is to limit or avoid drinking Kombucha in the days leading up to the test and inform the tester if you are concerned about a potential false positive result.


In conclusion, Kombucha is a fermented tea beverage known for its potential health benefits. While its low alcohol content generally does not pose a threat to drug test results, it’s essential to be cautious about your Kombucha intake before a drug test. By refraining from excessive consumption, choosing reputable sources, and being aware of the beverage’s alcohol content, you can enjoy Kombucha without negatively impacting drug test outcomes.
