Baking Soda detox. How to Pass a Urine Drug Test?

By | 18.12.2020


People use baking soda to beat tests for methamphetamine. Apparently, it blocks the excretion of methamphetamine in the kidneys for a period of time. It may therefore work for a urine, methamphetamine test. There’s no reason to think it may work for other tests. Also, too much baking soda can cause diarrhea, stomach rupture, electrolyte imbalances, and rarely fatality. We will describe how it is being used; however, we are making not recommendations. Use at your own risk or according to your doctor’s instructions as an antacid. In the table below, you can see Toxin Rid and Mega Clean.

Sodium bicarbonate, HCO3 is what is commonly called baking soda. The powder is white and somewhat salty. It is used as part of leavening bread. Sometimes it is used to prevent the growth of fungus. Baking soda and water to pass a drug test is used as an antacid to neutralize stomach acid, a mouthwash, and a laxative. In bicarbonate, loading athletes can use it to reduce muscle fatigue and soreness.

When might a baking soda flush drink work?

It will work in one specific case, for a urine methamphetamine test. In the past, it may be fooled other types of tests by making the urine more alkaline. It will no longer fool advanced tests except in the case of a urine methamphetamine test. In the urine methamphetamine test, baking soda is actually clean your body before the drug test reducing the amount of methamphetamine in the urine, it is therefore not technically fooling the test. Methamphetamine can be detected in your urine during the 3 to 5 days after use, so if you don’t have a week to wait it out, using baking soda as an antacid could reduce the amount of methamphetamine in your urine to below a detectable level.

Does baking soda detox your body for weed and other drugs? Baking soda Meth

No, baking soda will not help for a weed test. It will only help for a methamphetamine test and possibly other alkaline amphetamines. It does not remove any toxins from the body. It will make the stomach, blood, and urine less acidic. This can help with upset stomach and muscle soreness.

How it works in methamphetamine drug tests is theorized as follows. Methamphetamine is a base compared to blood, in other words, it is less acidic than blood. The kidneys remove methamphetamine at a predictable rate until, after about 5 days after last use, most of it is gone. It does this according to the electrochemical properties of methamphetamine compared to blood and the other substances in the blood. With the body removing the alkaline baking soda to maintain electrolyte balance, less of the methamphetamine will be removed by the kidneys to the bladder and into the urine. Therefore, the urine will contain less methamphetamine; hopefully below the cut-off level of detection.

The safe level of baking soda to take as an antacid is ½ teaspoon in 4 ounces of water, every 2 hours. You can try doing this every two hours on the day of the test, up to testing time. However, it is likely stronger measures will be needed to reduce blood ph enough to make a difference. So, first, let’s review the possible dangers.

Drinking baking soda to pass a drug test: dangers

You can overdose on ingesting a sodium bicarbonate remedy for passing pee meth drug testing. The biggest danger is taking too much baking soda can detox before drug tests cause severe gastrointestinal upset and diarrhea. Again, the safe, OTC level is ½ teaspoon, about two grams, in half a cup of water, every two hours.

In The American Journal of Emergency Medicine, a 1994 article describes the side effect of overdosing on baking soda:

  1. High blood pressure
  2. Hypernatremia, too high blood sodium
  3. Hypochloremia, low chloride level
  4. Hypokalemia, not enough potassium in the blood
  5. Kidney problems
  6. Low blood plasma
  7. Metabolic alkalosis, too much alkalinity in the blood
  8. Rupturing, bursting of the stomach wall[1]

In 2016, The Western Journal of Emerging Medicine presented a case study of a man who appeared to have suffered a baking soda overdose.[2] He was found wandering the streets mumbling and disoriented. He had a history of schizophrenia so it’s possible he was taking the baking soda to ward off some paranoid conception of illness or manipulation by unseen forces. The baking soda was found in this pocket. Baking soda, it should go without saying is not a drug of abuse and doesn’t cause any high. The subject’s body would flail on the gurney, he was possibly having mild convulsions due to electrolyte imbalances.

He appeared agitated, delirious, and would flail and slam his legs when strapped to a gurney, but most physical parameters were normal. He was stabilized and released after 4 days. Despite being a known polysubstance abuser, he tested clean for any drugs of abuse, which suggests baking soda might in fact mask drug abuse.

The Missouri Poison Control Center posted a case on its site of a man taking baking soda to pass a drug test, likely for methamphetamine. He took a whopping 5 tablespoons. For comparison, you should take ½ teaspoon as an antacid. For bicarbonate loading for athletic competition, an 80 kg man could take up to 24 grams of baking soda (and would expect some gastrointestinal upset). 5 tablespoons are 75 grams of baking soda. A loading dose for a cyclist 2 hours before the competition is about 1.5 tablespoons. This misguided fellow developed nausea, violent diarrhea, vomiting, stomach rupture, and sepsis. He had to have surgery and recovered and was released in under a month. Clearly, you don’t want to overdo this. If 1.5 tablespoons are enough to increase athletic performance, it is most certainly enough to make the urine more alkaline. Also, the test subjects didn’t have to sign a waiver to be administered 1.5 tablespoons of baking soda before testing for bicarbonate loading’s physical effects, so while above the OTC antacid dose, 1.5 tablespoons is at least safe enough for a scientific study.

3 tablespoons seem like too much. Remember, if you poo during the test and accidentally flush the toilet, your result may be disqualified. No more than 1.5 tablespoons appear to be needed to change the alkalinity of the urine.
