The Fast Marijuana Detox Kit is an effective same-day THC detox kit designed to help you pass a urine drug test for marijuana.

It allows you to pass an upcoming drug test even if you smoked the night before.

Here, I’ll review this detox kit in detail and discuss its effectiveness.

How does a Fast Marijuana Detox Kit work?

The Fast Marijuana Detox Kit utilizes a well-known and proven method for passing a drug test: flushing or cleansing.

To understand how it works, we need to grasp the concept of same-day detox. For that, I’ll explain the basics of how our body processes marijuana.

What is THC?

THC, or Tetrahydrocannabinol, is the primary psychoactive compound found in marijuana. It’s responsible for the plant’s most well-known effects, including the feeling of being “high.”

How marijuana is processed by the body

When you consume marijuana, THC enters your bloodstream, either through the lungs if you’re smoking or the stomach if you’re ingesting edibles.

Once in the bloodstream, THC travels to the liver, where it’s metabolized, or broken down, into metabolites. These metabolites are then excreted into the bladder and intestines.

About 70% of THC metabolites are excreted into the intestines, with the remainder going to the bladder.

From the intestines, some of the THC metabolites are reabsorbed back into the bloodstream through a process known as enterohepatic circulation.

The rest is excreted with feces. THC from the bladder is excreted with urine.

Why marijuana stays in your system for so long

THC is highly fat-soluble, meaning it binds readily to fat cells in the body. As THC travels through the bloodstream, it accumulates in body tissues, particularly fat cells.

Approximately 70% of consumed THC is trapped by these fat cells. When the body breaks down fat for energy, THC is released back into the bloodstream.

This process is quite slow, causing THC to continuously circulate between the body fat and blood. Only a small portion of THC is excreted.

As a result, THC can remain in your system for weeks or even months, continually moving from fat cells to the blood and back again.

How drug tests detect marijuana in the urine

Drug tests typically use strips with chemical reactants that detect the concentration of marijuana metabolites in the urine.

If the concentration of these metabolites is above a certain cutoff level, the test is considered positive.

Therefore, to pass a drug test, the concentration of marijuana metabolites in the urine must be reduced below this cutoff level.

The common cutoff level is usually 50ng/ml, although some drug tests use a more sensitive 20ng/ml threshold.


How the Fast Marijuana Detox Kit helps to pass a drug test

The Fast Marijuana Detox Kit is designed to target each step of marijuana metabolism, slowing natural detoxification process thereby reducing the amount of marijuana metabolites in the urine.

This makes it difficult for a drug test to detect marijuana, helping you pass the test.

Fat metabolism

First, the kit targets fat metabolism by blocking the breakdown of body fat cells.

This means that THC stored in body fat cells isn’t released into the blood and, consequently, not excreted into the urine.

Liver metabolism

Next, the kit contains ingredients that inhibit the enzymes responsible for THC metabolism in the liver.

This means that THC isn’t processed in the liver and, therefore, isn’t excreted into the urine and intestines.

Flushing drug metabolites

The next step involves inducing frequent urination. This process flushes marijuana metabolites from your system.

As you urinate more, the urine is replaced with new, clean urine because the body isn’t processing or excreting any new drug metabolites.

Consequently, your urine becomes clean and ready to pass the drug test.

Restoring urine parameters

The final step is crucial.

Your urine will be checked not only for drug metabolites but also for its validity.

The lab will perform a validity test checking essential urine parameters like creatinine levels and specific gravity.

As frequent urination can flush out essential minerals present in urine along with the marijuana metabolites, the Fast Marijuana Detox Kit includes ingredients that restore creatinine levels, specific gravity, and even the color of your urine sample.

This ensures your urine doesn’t appear diluted, helping you pass both the drug test and the urine validity test.


  • The Fast Marijuana Detox Kit works within just 60 minutes, allowing you to pass the test shortly after use.
  • The effects last for up to 5 hours, providing a sufficient window for testing.
  • It’s undetectable by drug tests — no lab can determine you’ve used this kit.
  • It’s legal — using this kit isn’t considered cheating ulike using fake urine.
  • It’s effective for any body mass and marijuana usage patterns.
  • Fast shipping is available — orders placed before 2pm are shipped the same day.
  • Overnight delivery options mean you can receive your kit the next day.
  • The kit comes with easy and clear step-by-step instructions.
  • It includes a comprehensive Healthy Detox Guide, a $60 value, at no additional cost.


It’s important to remember that this is a temporary solution.

The kit doesn’t remove drug metabolites from your body nor does it detoxify you.

  • It acts temporarily, allowing you to pass the urine drug test.Time management is crucial; the best effects are noted 2-3 hours after usage.
  • The kit comes in two options – for heavy users and light users.You should select the proper option for your needs.

What kind of drug test can the Fast Marijuana Detox Kit help to pass?

This kit is specifically designed to help pass a urine drug test.

It targets the drug metabolism in the liver and fat cells and flushes marijuana metabolites from the bladder. However, it doesn’t cleanse your blood or hair for drug tests.

If you need to pass a hair follicle drug test or saliva drug drug test, you’ll need a different approach.

How to pass a drug test with the Fast Marijuana Detox Kit

The Fast Marijuana Detox Kit is meant for use on the day you need to be clean. Here’s how to use it:

  2. Hydrate: Drink 20 ounces of water two hours before the test.
  3. Consume the Detox Drink: After waiting 20 minutes, drink the entire bottle of the detox drink included in the kit. If you have the “Extra strong” version, also take the extra energy booster tablets.

Where can I buy a Fast Marijuana Detox Kit?

The Fast Marijuana Detox Kit is a specific product that can only be purchased directly from Green Fleets.

Be wary of other websites claiming to sell this product under the same name, as they are often not legitimate and merely capitalizing on the search term to promote their websites.


I recommend this as an effective and safe solution to pass a drug test on the same day. Its effectiveness is based on scientific research.

However, it’s crucial to remember that the effects are temporary. You need to manage your time carefully and follow the instructions precisely.

So, if you need such a product, I can definitely recommend the Fast Marijuana Detox Kit.
