Methamphetamine creates an addictive sensation of relaxation or euphoria. It is classified as a Schedule II stimulant making it only legally available through nonrefillable prescriptions.

Meth is prescribed in controlled amounts to help in the treatment of ADHD (Attention Deficit Hyperactivity Disorder) and in some cases Parkinson’s disease. Meth is extremely rarely prescribed and even in such situations, the amounts are very low. 

Common or Street names for meth include Crank, Crystal, Glass, Ice, Poor Man’s Cocaine, Speed, etc.

How can I pass a Drug Test for Meth?

It is never recommended to cheat on these tests. If found, the consequences can be far more serious than getting a positive one. Here are some known methods of cheating how to pass a drug test for meth: 
  1. Substitution 
  2. Detox Drinks 
  3. Dilution 
  4. Adulteration 
  5. Abstinence 


Submitting a urine sample of another person who has not used methamphetamine is a common way to pass a drug test for meth. Most drug testing centers, like ours, require to submission of the sample under supervision so that it cannot be substituted. 

Detox Drinks 

It is popularly believed that consuming detox drinks can help you pass a methamphetamine drug test after using methamphetamine. These detox drinks do not have any scientific proof but are believed to flush out or mask the presence of drug substances. 


In dilution, the person who has used meth consumes a lot of water and sports drinks to dilute and flush out as much meth as possible. Diluting the concentration can be effective if you have used meth in a small amount and have enough time between the day of meth usage and drug test day. Drug test centers are able to detect such urine samples, so it is recommended to proceed carefully. 


Adulteration includes adding substances to the urine sample to block out the detection of methamphetamine metabolites. Common substances used to adulterate a urine sample are vinegar, bleach, laundry detergent, table salt, and Klear. It can be effective to cheat a drug test, but drug centers can find out if a urine sample is adulterated. 


Bleaching your hair is believed to break down the chemicals in the hair. There is not any strong proof of the effectiveness of this method but it is a popular one when hair test is involved. Drug test centers often are able to figure out if you are cheating through this method. 


The most effective way to get a negative result for meth or any drug test is to avoid its usage weeks before the day of the test. Analyze what sort of test they want to do (hair, urine, blood, or saliva) and how far back it can detect. 

Baking Soda to Pass a Drug Test

What is Baking Soda Flush?

Baking Soda Flush is a technique used to flush out drug substances from the body quickly. Baking Soda (scientific name: Sodium Bicarbonate) is a white alkaline substance used to relieve stomach pain, acid indigestion and sometimes heartburn. It is categorized as an antacid for this property.

How to Use Baking Soda to Pass a Drug Test

While baking soda is consumed for its limited health benefits, it is also used heavily to fool drug tests. In this process, the baking soda in powdered form is mixed with warm water and drank quickly. 

When baking soda is consumed with water in such a way, it initiates a chemical reaction which flushes out acid and during the process also helps flush out remains of drug usage from the body. Although there is not a scientific proof that has been found for this, people have found it useful. Baking Soda is also considered a powerful detox for these reasons. This method has been told to be effective for urine tests, however it fails against hair drug tests or Blood drug tests. 

We do not recommend using this technique to pass any drug tests as the results are not clear cut and the risks are greater than what the results can be. Overdosing on baking soda can lead to diarrhea, extreme dehydration, increased blood pressure, kidney failure, and heart failure.
