Failing a Urine Test

5 Ways People Keep Failing a Urine Test

You find a job you want and nervously submit your application. You wait with anticipation until you hear back: you got an interview. Awesome! Everything’s going great, and even better once you have a successful interview and get the call to tell you that you got the job.

But what’s next?

Ah, the urinalysis. Now you have to worry about that. Whether it’s a new job or your current position has recurring tests, the urinalysis is an unpleasant part of the work experience. Passing should be easy, but what if there’s a false positive?

Failing a Urine Test is a Genuine Fear for Many

False positives happen more than they should (which is not at all). Thanks to standardized testing that does not always account for everyday substances setting off alarms for illegal drugs, you’re right to be concerned. A

s Dee Giznik explains at, there are some common ways that might cause you to fail your screening.

Fortunately, we have you covered. Below are the five ways you might get a false positive for certain drugs. Stay aware of these and take steps where possible to avoid unnecessary problems at work.

Cold Medicine

We all know that awful moment when you wake up with a sore throat, a stuffy or drippy nose, a headache, and in addition to that, feel like death warmed over.

When you feel like that, you probably take a pill or syrup for it, or maybe a nasal inhaler. You want to feel better, after all.

The common cold is not only a very annoying thing to have to suffer through, but it can indirectly make you test positive for meth (amphetamines).

If your cold medicine or nasal inhalers contain antihistamines, they may influence your screening to show positive for meth. Check the ingredients on any cold medicine to see if it has antihistamines, and if so, avoid taking it until after your screening. Don’t let some sniffles and coughs get you into trouble!


You’re having your morning coffee and bagel, and you have a headache. So what do you do? Pop an ibuprofen before work so that it doesn’t distract you.

Or maybe you’re still healing from an injury, or you suffer from chronic aches, so you take some ibuprofen for that. Unfortunately, ibuprofen may cause you to test positive for cannabis (marijuana).

If you have a urinalysis coming up, make sure you stop taking ibuprofen or take note of the last time you took some, in case you want to notify your boss.

Whatever your feelings on medical cannabis, no one wants ibuprofen to make you look like you’ve been taking it when you’re not supposed to. The problem with everyday things like ibuprofen is that you don’t necessarily remember taking them.

Antibiotics and Other Prescribed Medication

If you’re dealing with an infection or other problems, the medicine you’re taking to deal with it could ruin your clean screening. What is this? Not only can cold medicine and pain-relievers screw you over, but also antibiotics? Is nothing safe?

I’m sorry to say that some antibiotics can cause you to test positive for opiates. Some of these medicines are called “cross-reactive substances” because, to the test, they appear similar to illegal drugs.

Check out this article on Drug Tests in Bulk for more information on why some of these medicines can cause false positives at your screening.

Other prescribed medicines may cause problems as well if they are at all similar to the substances being tested for. If you’re on antibiotics, let your boss know in case it messes up the test.

Poppy Seeds and Other Innocent Substances

I don’t know about you, but I love a good poppy seed muffin. Or poppy seed bread. Or poppy seed chicken. Or poppy seed chicken casserole…You get the idea.

Poppy seed is very common and very delicious and very harmless. The problem is, poppy seeds can make you test positive for opiates.

Think about that next time you’re eating the heavenly bread of betrayal. Keep your poppy seed consumption limited to days when you don’t have a screening. Otherwise, no judgment here, enjoy as much poppy seed as you want.

Another “substance” that can betray you is coca tea. Also called mate de coca, coca tea is made from the same coca plant as, you might have guessed it, cocaine.

So while it may be delicious, avoid that coca tea if you have a screening coming up. You shouldn’t have to worry about what foods you’re eating and whether they will make it look like you’re taking opiates, but unfortunately, that’s what we are warning against as it can be a problem.
