Can Kava Cause a False Positive on a Drug Test?

Kava, derived from the roots of the Piper methysticum plant, is a popular herbal supplement known for its calming effects. While kava itself is not a controlled substance and is legal in many places, there is some concern among users about whether it could lead to a false positive on a drug test. Here's what you need to know:

1. Understanding False Positives

A false positive occurs when a drug test mistakenly indicates the presence of a substance that the individual has not actually taken. This can happen due to various factors, including cross-reactivity with other substances that the test cannot distinguish from the target drug.

2. Kava and Benzodiazepine False Positives

One of the primary concerns with kava is the potential for a false positive for benzodiazepines. Benzodiazepines are a class of medications commonly prescribed for anxiety, insomnia, and other conditions. Kava and benzodiazepines both affect the GABA receptors in the brain, although they do so in different ways. Despite this difference, there have been rare reports of individuals testing positive for benzodiazepines after consuming kava.

The structure of kavalactones (the active compounds in kava) is different from that of benzodiazepines, so most drug tests should not mistake one for the other. However, in certain sensitive or less specific tests, cross-reactivity could potentially occur, leading to a false positive.

3. How to Handle a False Positive

If you believe that your kava use has caused a false positive on a drug test, consider the following steps:

• Inform the Testing Agency: Let the agency know that you have been using kava. Provide them with the product label or documentation if possible.
• Request a Confirmation Test: If a false positive occurs, ask for a more specific confirmation test, such as gas chromatography-mass spectrometry (GC-MS), which can more accurately identify substances and typically clears up any confusion caused by the initial test.
• Document Your Supplement Use: Keep records of any supplements you take, including kava. This documentation can be helpful in explaining any unexpected results.

4. Reducing the Risk of False Positives

To minimize the risk of a false positive, you might consider stopping kava use several days before a scheduled drug test. The duration kavalactones remain in the body can vary, but they generally have a relatively short half-life, so discontinuing use ahead of time can help reduce any potential cross-reactivity.

Conclusion

While kava is generally safe and unlikely to show up on standard drug tests, there is a small chance it could cause a false positive for benzodiazepines. Being proactive by informing the testing agency and requesting confirmation testing can help ensure that any false positive results are quickly resolved.

FAQs About Kava and False Positives

Q: How common are false positives from kava? A: False positives from kava are rare, but they can occur, particularly with less specific drug tests.

Q: What should I do if I get a false positive after using kava? A: Inform the testing agency about your kava use and request a more specific confirmation test to clear up any inaccuracies.

Q: Can stopping kava before a test prevent a false positive? A: Discontinuing kava use several days before a test can help reduce the risk of a false positive, as the body clears kavalactones relatively quickly.
