What if I flush the toilet during a drug test?

People Reviews

I recently had to take a drug test for a job. The person told me not to flush the toilet, but out of habit, I did. I am worried it will affect my results. If you have had experience giving drug tests, could you let me know if this has happened to you, and what results I could expect?

You peed in a cup right?
The toilet flushing rule is because they put blue dye in the toilet bowl, if you actually peed, then the water will turn green. That’s because we typically pee more than what is needed. This is to make sure that you aren’t using someone else’s urine.
I would just assume that they will ask you to retake one.
Did you not tell them when you did it?
Edit: Like I said, you probably will be asked to do another one and make sure that you don’t flush. They use the dye to catch people who are using other people’s urine.

It really depends upon the protocol of the person doing the testing. For example, DOT drug test protocol states that if a person flushes the toilet during the urine collection, it is considered and attempt to adulterate the urine sample. For DOT tests, the urine specimen collector immediately performs an “observed collection” (to make sure they get a good sample). For your school it depends upon their protocol. It could be similar to DOT or not. You would have to read their policies and proceedures manual for drug testing to know for sure.

I had one at school. I think it’s just incase there is a problem with the cup. I’m not sure though, good luck!

I would think that it just means your test will be weaker than usual.

What if I flush the toilet during a drug test?

There are a few things you should know about drug tests if you’re ever planning on flushing the toilet during one. First of all, drug tests use urine as a sample – which means that any substances that are flushed down the toilet will be detected. Secondly, most drug tests look for metabolites – which are the byproducts of the drugs your body is trying to eliminate. So if you flush during a drug test and the test administrator knows about it, they’ll be able to detect the metabolites even if there’s no actual drugs in your system.

The Basics of Drug Testing

When you think of drug tests, you probably picture a urine test. But urine testing isn’t the only way to detect drugs in your system. In fact, most drug tests involve testing for either drugs or their metabolites.

Metabolites are the byproducts of a drug’s metabolism in the body. They’re created when the body breaks down drugs into their component parts.

Drug metabolites can be used to detect drug use even if the user has not taken the drug recently. This is because drug metabolites can remain in a person’s system for days or weeks after an exposure.

A few key points to keep in mind about drug testing:
– Metabolites can be used to detect drug use even if the user has not taken the drug recently.
– Drug metabolites can remain in a person’s system for days or weeks after an exposure.

How Do Drugs Get into the Urine?

Drug testing is a common method of employers and law enforcement determining if an individual has been using drugs. While many people know that drugs can be detected in urine, there are other ways that drugs can get into the urine. In this article, we will discuss some of the ways that drugs can get into the urine.

The most common way that drugs get into the urine is through swallowing. When someone swallows something, it goes down into their stomach and then their intestines. The intestines are full of bacteria, which break down food into nutrients and enzymes. These enzymes can break down drugs, which is why they are seen as a sign of drug use.

Another way that drugs can get into the urine is through inhalation. When someone smokes marijuana or cocaine, they are taking in the drug directly through their lungs. This means that the drug will stay in their system for a longer period of time than if it was ingested or smoked.

Finally, some drugs can be absorbed through the skin. This includes heroin and cocaine, which can be absorbed through open cuts or wounds on the skin.

What to Do If You Flush the Toilet During a Drug Test

If you are ever faced with a drug test and you flush the toilet during the test, there are a few things that you can do to try and minimize your chances of being caught. First, make sure you do not have any drugs in your system when you flush the toilet. If you do not have any drugs on you, then the urine will most likely not show up on the drug test. Second, make sure that the urine is cleaned up as much as possible. Urinating on the ground is not going to help matters at all. Finally, be honest about what happened and tell the drug testing company what happened. They will understand and hopefully they will be lenient with you when it comes to your punishment.


If you’re concerned about getting caught using drugs, one of the best ways to avoid suspicion is to stay clean off-the-clock. However, there are times when even the best plan goes awry. Maybe you had a drink earlier in the day and decide to flush your toilet as an accidental way of hiding the evidence. Or maybe you used someone else’s urine sample and didn’t realize it until after you flushed. In either case, if you’re worried about getting caught during a drug test, here are some tips on how to deal with flushing during a drug test:
