Does baking soda detox your body?

Based on the findings of our research, baking soda could increase the alkalinity of blood and urine. Baking soda has the potential to pose as a buffer zone against acidity. Moreover, baking soda can help with sore muscles and improve several endurance measures during the bicarbonate loading process. Additionally, baking soda has an antacid role too. While baking soda has several effects, as you can see, there is no evidence it can eliminate toxins.

Is it possible to use baking soda to flush the system?

So, does baking soda flush your system as people believe? Baking soda can elevate the pH value of urine and blood. This particular effect may have a subtle impact on the way kidneys excrete molecules. However, it may not have a major influence on toxins, besides methamphetamine, possibly. Apparently, the pH value of the methamphetamine is alkaline. For that reason, users may have a little timeframe within which kidneys are inhibiting excretion of meth in an aspect of alkaline baking soda overload. That’s why the use of baking soda is theorized to be helpful for users to pass a drug test for meth and potentially other drugs from amphetamine class. However, the method is not considered effective for other substances, including THC.

Does drinking baking soda and water help you pass a drug test?

More precisely, does baking soda cleanse mask the use of drugs or is it possible to use baking soda cleanse to pass piss drug test?

Dangers of drinking baking soda

Consumption of higher amounts of baking soda comes with the risk of several side effects. You see, the reason baking soda works as an antacid is because it can neutralize hydrochloric (stomach) acid. If a person takes ½ teaspoon of baking soda they may experience relief. However, consuming several tablespoons of baking soda can irritate the gastrointestinal tract. As a result, many people could experience adverse reactions such as dehydration, diarrhea, and vomiting.

Dangerous baking soda case

Missouri’s poison control system reported a case of a man who attempted to pass a drug test using baking soda. He ended up with a hole in the stomach, which may have resulted from vomiting. To pass a drug test for cannabis the man had taken five tablespoons of baking soda. However, even people who claim baking soda works, say it’s only effective for methamphetamine. That means the attempt to pass a cannabis test with this method is entirely misguided.

Misuse of baking soda can lead to serious metabolic alkalosis. In 2018, Emergency Medicine Australasia published a case study wherein the abuse of baking soda led to cerebral infarction and death (F, Finn, and B).

The Western Journal of Emergency Medicine published a case study in 2016, which revealed ingestion of baking soda caused hemorrhagic encephalopathy and severe conditions that may lead to death (Hughes, Brown, and Valento).

A 2018 case study reported excessive consumption of sodium bicarbonate i.e. baking soda led to metabolic alkalosis which then caused cardiac arrest (G, T, and M).

What we can conclude from the abovementioned case studies is that excessive intake of baking soda could be dangerous and fatal even.

Pretty amazing, hilarious, or should we say awesome review appeared on Quora, a popular answers site. The story looks genuine, or legit.

Negative Review

Drug test with baking soda negative review

This particular user claims it doesn’t work. We should take his response with a grain of salt because the approach he used was too simple. The fact we all know is that there are strategies to pass drug tests, but the question is whether this specific method is effective. Also, water doesn’t really flush the system, it dilutes the urine. This user doesn’t know the basics of the subject despite his long history of drug use. Since he doesn’t have good tricks, it’s easy to say all this is quite difficult for him.


Social media users agree baking soda and water can be effective for masking meth use for about five hours. This method isn’t effective for other substances, including THC. The shortcoming of baking soda use is that it can be quite dangerous. Excessive intake can lead to an imbalance of electrolytes. This can lead to stroke, seizures, and even death. It could also cause brain damage meaning you would spend the rest of your life in a vegetative state. Drinking baking soda dangers also include a lot of vomiting. 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 try using baking soda for its antacid properties and follow the instructions on the box. For example, you can consume ½ teaspoon of baking soda every two hours, but avoid ingesting more than seven teaspoons per day. This amount is enough to modify alkalinity and thereby help pass the methamphetamine test. That being said, you have way better options as an alternative to this one. The most effective strategy to successfully pass a urine drug test is dilution.
Baking soda
To execute the dilution method properly, you need water with creatine, B vitamins, and electrolytes. Most detox drinks work via dilution. The method is easy; you just drink a certain amount of water for a specific period of time before the test to make sure you urinate 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 method to pass a urine drug test with your own urine. Do not drink too much water because it can induce water intoxication is an electrolyte imbalance that 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. For this purpose, there are a few products considered popular among online users who purchased and used them to successfully get a job or pass a drug test that was court-mandated. Keep in mind some states forbid the use of detox products or purchasing synthetic 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.
