How to Pass a Urine Drug Test Using Baking Soda

Do drinking baking soda and water help pass a UA drug test?

This appears to be a method of passing a drug test which is of medium popularity online.

Drug users have moved on to far more complicated measures, but this is one that is still around.  Before you decide to use this method, you should understand that it can be dangerous, and read all the warnings on this page and scientific sources.  Here is how it works:

Ingredients:

  • A glass of water, at least 8 ounces
  • 2 tablespoons of baking soda.

Step by step guide:

  1. Mix your two tablespoons of baking soda into your glass of water and drink it down.
  2. Refill the glass and drink again.
  3. Pee two or three times.
  4. Go to your test and catch the midstream urine.

Does baking soda detox your body?

According to our research, baking soda can make blood and urine more alkaline.  It can act as a buffer against acidity and may improve muscle soreness and some measures of endurance during a process called bicarbonate loading.  It can also act as an antacid.  Beyond these effects, there is no evidence that it removes toxins from the body.

Does baking soda flush your system?

Baking soda will increase the ph of your blood and urine.  This will have a small effect on the way molecules are excreted by the kidneys but is not expected to have a significant effect on any toxins, except possibly methamphetamine.  Meth apparently has an alkaline ph and this somehow gives users a period of time when the kidneys are blocking meth from excretion in the context of an overload of alkaline baking soda.  It is claimed that this is the method by which baking soda can help users pass a test for methamphetamine and possibly other amphetamines.  It is not expected to work for THC or other drugs.

Can you use a baking soda cleanse to pass a piss drug test?

In other words, does it mask drug use?  The simple answer is no, not according to our research.  If anything, it may decrease the excretion of methamphetamine but not otherwise affect the accuracy of the drug test.

Drinking Baking Soda Dangers

There are several dangers associated with drinking larger amounts of baking soda.  Baking soda is used as an antacid because it neutralizes hydrochloric acid aka stomach acid.  This provides some relief if you take only a half teaspoon of baking soda.  If you take several tablespoons, it will greatly irritate the gastrointestinal system.  Many people will experience vomiting, diarrhea, and dehydration.

Dangerous baking soda case
Here the poison control system of Missouri reports on a case of a guy who used baking soda in an attempt to pass a drug test and ended up busting a hole in his stomach, possibly from vomiting so hard.  He had taken five tablespoons of baking soda in order to try to pass a test for marijuana.  Even those who claim it works, claims it only works for methamphetamine, so the whole effort to pass a marijuana test with this approach is fully misguided.

Baking soda misuse can cause severe metabolic alkalosis.  In a case study published in Emergency Medicine Australasia in 2018, the abuse of baking soda resulted in cerebral infarctions and death (F, Finn and B).
A case in the Western Journal of Emergency Medicine in 2016 showed baking soda ingestion as the cause of a cause of Hemorrhagic Encephalopathy, and dangerous condition which can lead to fatal outcomes (Hughes, Brown, and Valento).

A 2018 case presented a cardiac arrest caused by metabolic alkalosis from using too much sodium bicarbonate aka Baking Soda (G, T, and M).
We see from these case studies that using too much baking can be dangerous and even fatal.

Social Media Reviews

Positive Review

Drug test with baking soda positive review

This awesome, hilarious story appeared on the Quora answers site.  It seems pretty legit.  The respondent left what appears to be his real name and picture but we omitted it here since we don’t want the guy to get in trouble at his job.  He also confirms it only works for methamphetamine.

Positive Review

This Quora responder also confirms that baking soda will help you pass a drug test for methamphetamine.

Negative Review

Drug test with baking soda negative review

This respondent feels the answer is no.  We can reject his answer due to his simplistic approach.  We already know there are ways to beat drug tests, the only question is does this particular one work.  Also, water doesn’t really flush the system, it dilutes the urine.  He has no understanding of the basics of dodging drug tests despite a long drug history which must have been really hard given his lack of good tricks.

Conclusion

The consensus of social media appears to be that it can work to mask methamphetamine abuse for a window of 5 hours but does not work for other drugs.  However, the drawback is that it can be very dangerous.  It can cause your electrolytes to become off balance which can lead to seizures, strokes, and death.  It could also cause brain damage and you could spend the rest of your life as a vegetable.  It’s not worth the risk.  However, if you just need something to give you a little confidence before you take a test where you might fail for methamphetamine, it won’t hurt to use baking soda as an antacid and follow the instructions on the box.  You can take a ½ teaspoon every two hours with a limit of 7 teaspoons in a day.  That should be sufficient to induce a change in alkalinity and that might help with a test for methamphetamine.  Of course, there are much better alternatives.  Dilution is the best method for passing a urine drug test.
Baking soda
In order to do a successful dilution, you need to have water with electrolytes, creatine, and b-vitamins ready to go.  Most detox drinks work via dilution.  You simply drink a reasonable amount of water over a period of time leading up to the test such that you are peeing frequently.  You take a b-vitamin because your dilute urine will not be a bright yellow color unless you take some.  Also, your urinary creatinine levels will be low and test makers will be testing for it, therefore you take a creatine supplement.  You pee at least 3 times, then catch your sample pee midstream and you have diluted urine which is masked.  This is the best and most trusted way to pass a urine drug test with your own urine.  Do not drink too much water as this can cause water intoxication which is an electrolyte imbalance which can be fatal.
The next sometimes effective method that people use is to substitute their urine with a clean sample.  You can do this by asking a clean friend for a sample of urine and paying for the time and effort.  You can also do this by purchasing trusted synthetic urine.  There are several products which are popular and attested to by online users who claim the product worked for them and they got a new job or passed a court-mandated drug test.  However, in some states, it is not legal to use detox products or purchase fake urine.  So, you should be sure to check your state’s laws before trying any kind of tampering with the results of any drug test.
