Do Laxatives Help to Detox and Pass a Drug Test? (yes and no)

Yes, theoretically, laxatives can help pass a drug test by increasing the speed of detoxification from marijuana. About 60% of excreted THC is excreted through the intestine, and part of this THC is reabsorbed back into the blood.

So theoretically, laxatives can help to clean your system of THC faster. Below we’ll explain this idea.

How Laxatives Can Help To Pass a Drug Test

While drug tests look for the marijuana metabolites in the urine, most of these metabolites are excreted in the feces.

From the intestines, part of this THC is reabsorbed back into the blood through the process called enterohepatic circulation.

Part of this reabsorbed THC will be excreted into the urine. I think you’ve got the point.

The longer THC stays in the intestines, the more of it will be reabsorbed back into the blood and end up in urine.

Laxatives help excrete THC from the intestines faster and thus help clean your THC system faster and pass a drug test.

This will only help if you are trying to detox from marijuana completely. The method makes no sense for the same day flushing before a drug test.

But that’s a theory based on marijuana metabolism research. No scientific data can help estimate the amount of THC reabsorbed and the exact effect on marijuana detoxification.

Side effects

Like most medicines, laxatives can cause side effects. They’re usually mild and should pass once you stop taking the laxative.

The side effects you may get will depend on the type of laxative you’re taking, but common side effects of most laxatives include:

bloating
farting
tummy cramps
feeling sick
dehydration, which can make you feel lightheaded, have headaches, and have pee that’s a darker color than normal
