Does Baking Soda Help Pass a Drug Test?

The effectiveness of baking soda in passing drug tests is a matter of debate. The reason why this question exists is that baking soda is known to retain drugs from amphetamines group in the system. This may lead to an undetectable amount of drug excreted from the body with urine and therefore negative drug test result. In this article we will discuss whether baking soda really helps pass a drug test.

Does Baking Soda Flush Drug Out of the System?

No, baking soda does not cleanse the system. Its main component—sodium bicarbonate—only reduces its acidity making the urine and blood more alkaline. According to studies, alkaline urine decreases the renal elimination of amphetamine drugs, such as methamphetamine. This means that your urine will have less drug metabolites before your drug test, which will increase your chances to test negative.

Does It Help Pass a Drug Test?

In view of the foregoing, we can assume that baking soda helps in passing urine test for meth as well as for other amphetamines to a certain extent. This, however, has not been proven by any scientific research, so we don't know for sure what dose is required, and for which drug concentrations this may or may not work.

On the other hand, baking soda will not help you pass a drug test for marijuana, because its main metabolite THC-COOH is acidic substance. According to the aforementioned studies, weak acids are excreted faster in alkaline urine, which actually means that baking soda will increase concentration of THC-COOH in your urine, and therefore your odds to test positive. So, consuming this powder from your kitchen before a urine test for marijuana will make you fail it rather than pass!

If you want to pass a drug test for weed, you must use proven means, such as THC detox drinks.

How to Take Baking Soda to Pass Urine Test for Meth?

For the method to work effectively, you must know how much baking soda should be used and the way it should be consumed. Although there is no science behind it, we have numerous reports from people who passed meth tests successfully, so we can use their advice.

The classic recipe implies mixing 2 tablespoons (1 ounce or 30 grams) of baking soda with one glass of water (8 ounces or 240 milliliters). Some people, however, recommend using 1 tablespoon for every 50 pounds (22 kilograms) of your body weight with 20-30 ounces of water (in total). Dosing of any remedy depending on the user's body weight sounds reasonable, but you must also remember that your baking soda dosage depends on your current blood pH also, so you may not need that much. We urge you to be very careful not to overdose baking soda, because it has dangerous side effects.

The following are recommended steps to pass urine test for meth:

  1. Two hours before the test, mix baking soda with water and drink it.
  2. Drink at least one glass of pure water after that and keep drinking as much as you want until the test.
  3. Do not empty your bladder until you feel like it's full. You have to manage your urination so that you urinate 2 times before sending a sample. Your 3rd pee will be the cleanest and it must go to a test cup.

It is worth mentioning that this method has negative reviews also, so it is not a 100% guarantee.

What Are the Side Effects of Baking Soda?

The effectiveness of this method comes with certain side effects that you should be aware of before giving it a try.

Small doses of baking soda do not harm, but consuming this substance in excess can result in severe neurological as well as metabolic issues. They are as follows:

  • diarrhea,
  • nausea and vomiting,
  • headaches,
  • fatigue,
  • muscle spasms,
  • thirst,
  • frequent urination,
  • bloating of stomach (feeling full),
  • swelling of the lower limbs.

Baking soda is a non-toxic substance, so mild overdose is not a life-threatening condition. In severe cases, however, it may cause acute kidney injury, dehydration, electrolyte imbalance, hypernatremia, muscle weakness, heart rhythm disturbances, shock and intracranial hemorrhage. Fatalities are extremely rare, but if you experience severe symptoms, you should seek medical attention. Activated charcoal can be used as first aid in this situation.


Whether baking soda helps pass a drug test depends on the type of drug you are using. This substance increases the pH level of urine, which masks alkaline drugs, such as methamphetamine, but exposes acidic substances, such as THC from marijuana. Consuming baking soda with water is considered an effective way to pass a drug test for amphetamines, but you must be careful with the dosage to avoid overdose. Above is all the necessary information, so that you can make the right decision.
