Understanding False Positive Drug Tests: Valium and Other Substances

Drug testing is a routine part of the hiring process for many jobs, but sometimes, the results can be misleading. If you've recently failed a work drug test for a substance you were prescribed, such as Valium, the situation can be quite distressing. Likewise, if you've used recreational drugs like marijuana (weed) or MDMA, it can lead to a failed drug test. Here's what you need to know about these situations, including how the testing process works and what steps you can take if you believe you have a false positive.

Why Did I Fail the Drug Test?

When it comes to drug tests, there are a few key substances that are commonly screened for, including marijuana, methamphetamine, cocaine, and amphetamines. Even if you have a prescription for a substance like Valium (also known as diazepam), the test might still show a positive result. This is because standard drug tests are designed to detect the metabolites of various drugs, not just the active compounds in a prescription medicine.

In your case, the failed drug test could be due to the use of marijuana and MDMA. These substances are known for their metabolites that can persist in the body for days or even weeks after use. The initial drug test often uses a lateral flow immunoassay, which can sometimes give false positives. However, the employer should send a second specimen for a confirmatory test via mass spectrometry, which is much more accurate.

Possible Causes of the False Positive

There are several reasons why you might have received a false positive drug test result:

Recreational Drug Use: If you used marijuana or MDMA, these substances can leave metabolites in your system for an extended period. Prescription Medication: The active compounds in Valium can sometimes cause a false positive in standard tests. Environmental Factors: Certain environmental factors, such as exposure to contaminated surfaces or devices, can also lead to false positives. Medication Contaminants: Sometimes, supplements or other medications can contain traces of substances that can cause a false positive.

What to Do if You Have a False Positive

Here are some steps you can take if you believe your drug test was a false positive:

Request a Second Sample: Ask your employer for a second sample to be sent for confirmatory testing via mass spectrometry. This test is highly accurate and can detect even trace amounts of substances. Contact Your Doctor: Speak to your doctor about any medications you are currently taking. They can provide information on why you might have tested positive and what steps you can take to avoid a false positive in the future. Review the Testing Process: Learn more about the testing process and what substances are being screened for. Understanding the testing process can help you better prepare for future tests. Advocate for Yourself: If the employer continues to insist that you have failed the test, consider talking to a legal professional to understand your rights and options.

Key Takeaways

- **Drug Tests are Not Always Accurate:** The initial test might be a lateral flow immunoassay, which can sometimes give false positives. Confirmatory testing via mass spectrometry is much more accurate.

- **Prescription Medications Can Cause False Positives:** Valium and other prescription medications can sometimes cause a false positive in standard tests. Always discuss your medications with your employer's testing administrator.

- **Recreational Drug Use:** Marijuana and MDMA can leave metabolites in the system for days or even weeks. If you have used these substances, be prepared to explain your usage to your employer.

- **Environmental Factors:** Consider all potential sources of contamination, including devices, surfaces, or supplements, when preparing for a drug test.

By understanding the testing process and taking proactive steps, you can increase your chances of having a fair and accurate test result. Remember, clear communication and seeking help from professionals can make a significant difference.
