Don’t Be Fooled by These 10 Drug Testing Myths

by | Jun 2, 2023 | Drug & Alcohol, Employer Solutions

Drug testing is a common procedure in various settings, such as the workplace, sports, and even during legal proceedings. With the prevalence of drug testing, it’s not surprising that numerous myths and misconceptions have arisen surrounding the topic. To help dispel these myths and provide a better understanding of drug testing, we’ve compiled a list of the top 10 drug testing myths you should be aware of.

1. Myth: You can easily cheat a drug test using home remedies or commercial products

Fact: While there are many products and home remedies claiming to help you pass a drug test, the majority of these methods are unreliable and ineffective. Drug testing labs have evolved to detect many of these “cheat” methods, which can result in a failed test or being flagged as suspicious. Additionally, attempting to cheat a drug test can result in serious consequences, including job loss or legal penalties.

2. Myth: Poppy seeds can lead to a failed drug test.

Fact: Although some food items, such as poppy seeds, contain trace amounts of opiates, most drug tests are designed to account for this. It would require consuming an unrealistic amount of poppy seeds to reach the threshold for a positive opiate test result. Nevertheless, if you have concerns, it’s best to avoid consuming large quantities of such foods shortly before a drug test.

3. Myth: You can flush, drink, or take supplements to dilute your urine and pass a drug test.

Fact: Diluting your urine may seem like a plausible way to pass a drug test, but most modern drug tests can detect when samples are diluted. Drinking excessive amounts of water, taking diuretics, or consuming detox supplements can not only be ineffective but also dangerous to your health. Labs may also report diluted samples as invalid or suspicious, which could result in further testing or consequences.

4. Myth: Hair drug testing can detect drug use from many years ago.

Fact: Hair drug testing typically analyzes the most recent 1.5 inches of hair growth, which provides an approximate window of detection for up to 90 days. While it’s true that drugs can remain in your hair for a longer period, hair tests are designed to detect recent drug use, not past usage from years ago.

5. Myth: Prescription medications won’t cause a positive result on a drug test.

Fact: Some prescription medications can cause a positive result on a drug test, as they may contain substances similar to those being tested for. For example, certain pain medications may contain opioids, which could trigger a positive result for opiates. If you have a prescription for a medication that might interfere with a drug test, it’s essential to disclose this information beforehand to avoid any misunderstandings.

6. Myth: A positive drug test result automatically means you’ll be fired or face severe consequences.

Fact: A positive drug test result doesn’t always lead to immediate termination or harsh penalties. Employers and organizations often have specific policies in place regarding drug test results, which may include offering support, counseling, or rehabilitation programs. In some cases, employers may allow employees to retain their job if they comply with these requirements and remain drug-free.

7. Myth: All drug tests are the same and test for the same substances.

Fact: Drug tests vary significantly in their methodologies, detection windows, and the substances they screen for. There are different types of drug tests, including urine, hair, saliva, and blood tests, each with their own unique advantages and limitations. Test panels can also range from detecting a few substances to an extensive list, depending on the employer’s requirements and the specific test ordered.

8. Myth: Drinking vinegar or lemon juice will help you pass a drug test.

Fact: The notion that the acidic properties of vinegar or lemon juice can cleanse your system of drug metabolites is a myth. There is no scientific evidence to support this claim. Using vinegar or lemon juice to manipulate drug test results is not only ineffective but can also lead to stomach discomfort and other health issues.

9. Myth: Exercising vigorously before a drug test will help you pass by eliminating drugs from your system faster.

Fact: Although exercise can theoretically increase the rate at which your body metabolizes certain substances, it is unlikely to have a significant impact on drug test results. Most drugs have specific half-lives and metabolic rates, which are not easily altered by exercise alone. In some cases, strenuous exercise immediately before a drug test could potentially release stored drug metabolites from fat cells, leading to higher concentrations in the bloodstream and a higher chance of detection.

10. Myth: Hair dye or hair treatments can alter the results of a hair drug test.

Fact: While there is a misconception that hair dye or treatments can mask drug metabolites in hair samples, hair drug tests are designed to detect substances within the hair shaft, not just on the surface. Some chemical treatments may partially affect the concentration of drug metabolites, but they are unlikely to completely alter the results. Modern drug testing laboratories use advanced techniques to minimize the impact of hair treatments on test outcomes and ensure accurate results.


Understanding the facts about drug testing is crucial to help dispel common misconceptions and ensure you’re well-informed about the process. While drug tests are not infallible, they have become increasingly accurate and sophisticated over the years. It’s essential to approach drug testing with honesty and transparency, as attempting to cheat or manipulate the results can lead to severe consequences.
