8 Items That Can Make You Fail a Drugs & Alcohol Test

Failing a Drugs & Alcohol Screening happens far more than you think!

As D&A screening becomes part of daily life within the construction & civil engineering industry it is essential to take a bit of time to understand that there are plenty of everyday foods and other harmless items that can be confused for illegal substances!

  1. Hemp Seeds

Whether you enjoy hemp seeds, hemp seed oil, or hemp seed milk, every single one of these items, especially if you consume them regularly, will cause you to test positive for THC. Although hemp seeds are legal, drug tests cannot tell the difference between marijuana users and hemp seed eaters. There are microscopic traces of THC in hemp seeds. You should also know that THC is stored in body fat, which means you will test positive for as long as 30 days after you stop eating it!

  1. Cold Remedies

Almost all over-the-counter cold and flu remedies work by narrowing the blood vessels in the nasal passages, which helps to relieve congestion. The ingredient in cold remedies that does this, pseudoephedrine, is a synthetic amphetamine, which can be used (in huge quantities of course) to make meth. Taking cold medication can cause you to test positive for amphetamines!

  1. Azo

If you have ever had a urinary tract infection, then you are familiar with this product that can give you some immediate relief. Azo strips your urinary tract, which is great for removing the bacteria causing the infection; however, many people use Azo to try to fool a drug test. Azo tends to turn the urine bright red or super yellow, which is usually a red-flag to test administrators who will automatically kick out your results, believing that you are trying to hide something.

  1. Sudafed

This is perhaps one of the most common offenders when it comes to failed drug tests. Sudafed is often mistaken on pee tests for numerous hard-core drugs. This is because, like most cold remedies, Sudafed’s main ingredient is pseudoephedrine, which is a type of synthetic amphetamine. Avoid Sudafed at least 48 hours before a drug test. If you take Sudafed for allergies, feel free to sneeze away during your pee test.

  1. Tonic Water

Are you kidding? That’s what we said when we found out about this! The truth is, tonic water, which is also known as quinine water, was originally made as a means of delivering quinine from South America. Drinking tonic water can lead to a false positive for opiates!

  1. Vitamin B Supplements

Many natural herbs that contain vitamin B2, or vitamin B complex supplements, can lead to a false positive. This is because most commercial B2 supplements (also known as riboflavin) are synthetic. These are made from the fermentation of a particular plant, or they can be products of hemp seed oil. As you might have figured out, this will give you a false positive for marijuana. Avoid taking vitamin B supplements until you know you have passed your drug test.

  1. Ibuprofen/Codeine

This every day, over-the-counter pain killer might be your first choice when it comes to relieving pain, but you should try alternatives should you plan to take a drug test within 48hours. This is because little old ibuprofen can cause you to test positive for barbiturates, marijuana, or benzodiazepines. Codeine, a commonly prescribed pain medication and also the active ingredient in some prescription cough medicines, and Meperidine are structurally related to morphine and could also cause false positive test results.

  1. Poppy Seeds

Many people enjoy poppy seeds in their muffins and bagels, but wait just a minute! If you plan to take a drug test in the near future, you should skip those delicious favourites until your first day on the job. Poppy seeds contain tiny traces of opiates, such as the kind found in codeine and opium. After eating something containing poppy seeds, you can test positive for these drugs for as long as 48 hours. It’s best to skip the poppy seeds for now, and enjoy some sesame seeds or sunflower seeds in the meantime
