After several years of working in one company, I was selected for a random urine drug test. While I was preparing for the test, I found out that even the meal you are taking can affect the result.

Traces of illicit illnesses could also appear if you did not consume drugs before the test but ate food that contained a legal amount of coca, or opium.

If you want to avoid the consequences of being tested positive, yet don’t have much time to search, read below the list of foods to avoid before a urine drug test.

5 Foods To Avoid Before a Urine Drug Test

If you occasionally enjoy booze after work, use opiates, or smoke marijuana for health treatment, there is an entire industry dedicated to passing that drug test.

According to a survey published by the Human Resources Management Association, about 57 percent of U.S. companies are occasionally checking their employees on drugs.

To pass the drug test, you should learn which ingredients are related to opiates and how to avoid them.

1. Poppy seedsFoods to avoid before a urine drug test: a jar full of poppy seeds

You’ve probably heard the story many times that your sample can be tested positive if you eat too many poppy seeds. But realistically, most of us considered it the most common legend that had no chance of being right.

What does it contain?

There are no drugs in poppy seeds, but these seeds and opium come from the same plant. Depending on the process, a poppy seed may contain some residue, affecting the final result.

Why should I stop consuming it?

Eating poppy seeds before drug tests can, in rare cases, detect the presence of opium in your pee sample. If your poppy seed bagel has only a few of them on it and you remove all of them, there is still a chance to receive a false positive.

That is why the American Anti-Doping Agency advises not to consume poppy before taking a drug test, as it can test positive. They say you can’t even predict how long morphine or morphine metabolites from them will stay in your system.

2. PizzaA plate full of pizza

We all love pizza, but believe it or not, it can make your drug test have a positive outcome.

What does it contain?

Research has shown that eating pizza can cause addiction because it contains yeast that makes pizza dough rise.

Why should I stop consuming it?

Yeast is fermenting sugar into alcohol, which can be enough to make your THC test positive.


3. Hemp Seeds Snack BarFoods to avoid before a urine drug test: a bowl with a scooper full of hemp seeds

You will most probably be surprised that your favorite snack bar can render positive results to your urine drug test.

What does it contain?

As the name suggests, it contains hemp, a breed that is legally produced in the US. It contains THC in a very low quantity of less than 0.3 %, yet easily traceable during testing.

Why should I stop consuming it?

If you are scheduled for drug testing, you should avoid hemp because it comes from the same plant as marijuana. Since it can be a common ingredient for your favorite snack bar, it would be better to stop consuming these products at least two days before your test.

4. Coca Tea A cup full of coca tea leaves

Even if you love drinking tea, avoid the one made from coca leaves before your drug urine test. People, especially those from South America,  use coca tea to stimulate stomach function and treat colds and other ailments.

What does it contain?

Coca leaves contain a psychoactive alkaloid, cocaine, so drinking coca tea can affect your results.

Why should I stop consuming it?

According to the researchers, labs can identify traces of these metabolites that can remain in our bodies for 36 hours.

5. Tonic Water A glass filled with tonic water

If you are consuming tonic alone or as a mix in another drink, try to avoid it before the drug test.

What does it contain?

It contains quinine, a compound from the cinchona tree, which gives a bitter taste to the drink. People who have malaria usually use quinine to treat this disease.

Why should I stop consuming it?

Tonic water contains a small quantity of quinine, and it is safe to consume. Still, if you consume even one glass of tonic before the test, your pee may contain traces of quinine and render your test positive.

What can affect urine samples?

What you consume can affect your urine sample. Some ingredients found in a grocery store near you can be harmful and have a positive result.

Some other factors like dehydration, medicines, and exercise are also essential to consider before you get tested.

What should I eat before a urine drug test?

Before going to the lab, try to eat healthy food. A poor diet with a lot of salt and sugar slows down the metabolism and causes water retention in the body. If possible, before testing, use many products with a lot of fiber and vitamins (fruits, vegetables, quality meat).

What foods should I stop consuming 24 hours before the urine drug test?

Foods you should avoid for at least 24 hours before the pee sample testing are those that contain a lot of salt and vanilla. To have good results, using vitamins, coffee, and alcoholic beverages is also not recommended.

Should I fast before the medical test?

Yes, you should fast before the medical test. Try not to eat or drink anything for at least 8 hours.

Conclusion – Foods to Avoid Prior To Testing

Depending on your health, avoid ingredients that can cause any possible doubt that opiates exist in your system. Marijuana, for example, needs a lot of time to get out of your body, so to pass the test, take care of what you are eating at least two days before.

Take your time and try to think of two things: “do’ and don’ts.” Drug tests are used to check your health conditions, and you can even be asked to come back and give another sample if they see something suspicious in the lab. If you like your job and don’t want to lose it, search for “do’s” only and try not to fail.

If being tested positive on opiates is not an option, get ready on time and search for foods to avoid before a urine drug test.
