Does pooping before a drug test help?

Yes, pooping before a drug test will help to remove marijuana from your system much faster and pass a urine drug test.

As we already explained in this article about 65% of the marijuana metabolites are excreted in the feces.

We’ll use THC as the name of THC and all of its metabolites here.

While THC is located in your intestines, it enters the process called enterohepatic circulation. In this process, THC is reabsorbed back into the blood from the intestines.

This means that it moves back into the blood and then part of this THC is excreted into the urine, lowering your chances to pass.

So when you empty your intestines, you remove that THC, prevent its reabsorption, and thus lower the concentration of THC metabolites in the urine.

Another method to prevent enterohepatic circulation is to use supplements that act like absorbents: activated charcoal, Certo, etc.

However, you should remember that this only helps you to pass. You should do all other steps to ensure that THC is removed from your system and your urine is clean before the test.
