According to the American Council for Drug Education, weed is the most commonly used illegal drug that features THC as the active substance. That is the main reason why most employers are fighting the war on drugs by routinely testing employees and applicants for patterns of abuse.
They are conducting narcotic tests in the form of hair, blood, and urine screenings so that they can determine the presence of active compounds and metabolites within the body.
However, consuming some nonprescription and prescription drugs may affect the testing results, which means that you may fail it even if you did not consume anything illegal.
Even though false-positive results are not that common in laboratory settings, if you decide to take home tests such as the one found in Wal-Mart, you will be able to fail it. Remember that it only happens to 2.5% of cases, so you have to avoid being part of these statistics.
What Is False Positive?
If you have to pass a narcotic screen, that may catch you off guard in most cases. Remember that screenings are standard as pre-employment processes in both government and private sectors, as well as for healthcare workers, students, athletes, criminals on probation and past users.
Even though tests are standard, the problem lies in idea that specific supplements, meds, and foods can lead to false-positive results.
Of course, laboratory testing features two-step verification when it comes to handling these issues, but in general, you may fail the screening even if you did not consume anything.
Consequences of False-Positive Results
Drug screening results may affect your current lifestyle and numerous situations that surround you. The screening settings are vital for accuracy, so if you wish to undergo a drug screen, we recommend you to do it in certified labs that already know how to deal with false positives.
According to statistics, between 5 and 10 percent of tests may be false positives, which lead labs to upgrade their equipment and testing devices so that they can reduce this particular issue.
However, failing a drug test may cause loss of employment, exclusion from competitive sports, jail time, improper medical care and loss of privileges during the probation. Therefore, you have to know how it works and what you should avoid consuming before the screen.
A Brief Guide on Lab Drug Testing
The initial drug screens are known, as immunoassays will check whether your sample is positive or negative shortly after you give the specimen.
The second step includes a GC/MS test that can determine whether positive results are conclusive, which will reduce the chances of false positives.
If both tests are positive, it means that you will fail the test. You should check out this site: https://drugtestingreviews.com/does-wal-mart-drug-test/ to learn everything about Wal-Mart drug test.
The best thing about GC/MS is the ability to identify specific compounds within the specimen, but it will not identify all potential compounds that may affect the results.
Immunoassay is a large-scale and quick screening, while GC/MS is specific and will differentiate substances within your sample. Therefore, when you take the urine, they will split it into two examples, in which one portion will be saved for confirmatory screening.
However, a drug screening will rarely report the presence of specific drugs in the immunoassay, which is why you should give your future employer the list of over-the-counter and prescription medicines you consumed in the past few weeks.
Prescription and Nonprescription Drugs That May Affect Your Testing Results
Remember that dronabinol features chemical THC, which is the active and psychoactive ingredient found in cannabis. Therefore, consuming it may affect the drug testing results, and in some cases, they may encounter in your system THC even if you did not consume it.

It is similar to ibuprofen because it can relieve stiffness, swelling, and pain, and it is a standard prescription for treating rheumatoid arthritis, as well as joint swellings.

means is another nonsteroidal anti-inflammatory drug that treats pain, stiffness and swelling in joints.

6. Poppy Seeds
Apart from medications, things you eat may also affect the results. Since poppy seeds are conventional on rolls, bagels, and pastries, you should know that consuming them before the test may lead to failing the test and having opioid inside the body.
Since poppy seeds feature codeine and morphine, you should avoid the consumption before the test because it may fail for opioids, and others will think that you are a heroin addict or even worse.
