How To Naturally Cleanse Your Body Of Thc? | How Long Does A Drug Test Take?

By Tommy Joyce |

There are many reasons you would want to cleanse your body of all THC and related byproducts. For most people, it’s either to pass a drug test or to reap the benefits of a tolerance break.

However, beating a drug test is a drastically different objective than ridding your system of cannabis. Typically, the need to beat a drug test arises on such short notice that it’s impossible to clear the body of THC and its metabolites – so the objective becomes to simply hide, or mask, any evidence of its existence. What does this mean? Abstinence is the only surefire way to rid your body of THC.

How THC is Stored In the Body

Before we can proceed, you must understand how THC and other cannabinoids are stored in your tissues. Following the consumption of cannabis, THC levels in the blood rise, and the cannabinoids (mostly THC, but also secondary players like CBD, CBN, and CBG) are metabolized to a variety of inactive chemicals, the primary being tetrahydrocannabinol carboxylic acid (THC-COOH). THC-COOH is what’s referred to as a metabolite, or natural byproduct, of THC.

The metabolites are what your body leaves behind after you have processed it, while the THC is what gets you high. Regular use causes a build up of both thepsychoactive and non-psychoactive cannabinoids in your body’s fat tissue. The molecule that is stored in fat is a lipophilic molecule.

How much THC is in my body?

This is a difficult question to answer as everyone is different, but we are all subject to the same factors that determine how much THC and its metabolites are in our system.

Frequency of usage

This is the most important factor, as regular use will cause the build up of both the THC and its metabolites in your tissue. On the other hand, the occasional smoker will not have a lot of build up in their body.


Each person has a different rate of metabolism that is determined by their genetics, height, weight, sex, and level of physical activity. The rate of metabolism is used to determine how quickly the THC is broken down, converted to metabolites, and eventually released from your system.

Body Fat

Fat cells hold the cannabinoids in their cells. The higher the concentration of body fat, the bigger the storage capacity for the cannabinoids.


Over time, the fat cells give way to the blood with the cannabinoids stored in them. Studies show that exercise can raise blood THC levels by releasing the drug from fat stores. Exercise has the potential to increase the rate at which your body releases stored cannabinoids.


Consuming potent, high-THC strains will result in higher levels of cannabinoids in the system. If you consume a low-grade street weed or a high-CBD strain, you will be able to lower your levels of THC.

How long does a THC detox take?

The answer to this question depends on how much is in your tissues. The type of test used to check for THC in your system is a very important distinction, in addition to the personal factors listed above. The most common forms of testing for cannabis use are these.

Urine test

This type of testing is cheap, non-invasive, and relatively accurate, which is why it is most common. Despite their popularity, urine tests don’t actually detect the drug in the body, but instead look for the metabolite. The urine tests do not detect the psychoactive cannabinoid, so they are not a way to measure impairment. The half-life of this metabolite is long and can be detected in urine for months after use. A one-time user can use urinalysis from 1 to 7 days after use, however, most will be below the positive threshold within a few days. A regular user can test positive for the THC metabolite over 90 days after the last time they consumed it.

Blood test

Blood tests can detect the active presence of the drug in the bloodstream. Within an hour after smoking cannabis, the levels of the main component of the drug begin to decline. It is a good sign that you have smoked recently if you have high levels of THC in your blood. It is worth noting that low levels of THC can remain in the blood for 8 hours or more without any signs of impairment in one-time users. If you are a chronic user of the drug, it can stay in the bloodstream for several days.

Hair follicle test

Highly sensitive jobs and those requiring special clearance are the types of jobs that hair follicle tests are reserved for. Hair follicle tests are the most objectionable form of drug testing because they don’t measure current use but rather non-psychoactive residues that remain in the hair months after use. They cannot be washed out by a shampoos. It is not likely that this type of testing will be sensitive to one-time cannabis users.

Saliva test

Saliva testing requires the use of a newer, less proven technology. Due to reliability problems, saliva tests for marijuana have yet to gain mainstream acceptance in the U.S., though they are sometimes used for their affordability, especially for high-turnover positions.

The question of how long cannabis stays in your system depends on whether or not you are being tested for the presence of THC itself or its metabolites. In one-time users, the compound is present for 12 to 24 hours, and in chronic users it is present for 14 days. For frequent users, the metabolites of THC can be detected for months after use.

If You Can’t Get Legitimately Clean in Time—You Can Still Beat The Drug Test

Your ability to beat a drug test will depend on your personal usage history, how long you’ve abstained, and which type of test is being administered. If you’re like 95% of people, you were just notified of your random urine test and you’re freaking out that you won’t pass it. It’s not a great situation, but there are things you can do to pass your test.

If you are looking for a quick fix, it is too late to get clean and you must attempt to beat the test. You have three options for a quick fix; dilution, adulteration, and substitution.

How to Get Weed Out of Your System


No anecdotal technique has been supported by the scientific community. Does your system work after being flushed out? It is dependent on all the personal factors we discussed. There are some strategies you can use to improve your chances of passing.

Is it the number one reason that dilution doesn’t work? The testing facilities are trained to flag samples that have been changed beyond normal levels. If you want to pass a drug test, you need to make sure the urine sample is not positive for THC while not notifying the facility that you took the sample. There are a few ways to help you do that.

Abstain immediately: If you haven’t already, stop consuming cannabis as soon as you are notified of your drug test. This may sound obvious, but continuing to consume is not going to help you pass the test.

Time: To reiterate, the longer you abstain prior to testing, the higher the likelihood you have of passing. The aggregate level of THC metabolites in your system will continue to decrease over time.

Exercise: The key with exercise is that it only helps if you sufficient time before your drug test, as it increases the rate at which your body releases stored THC and metabolites – not a good option right before you pee into a cup. Avoid exercise in the days immediately preceding your test. If you have a few weeks before the test, exercise will help.

Diet: The key here is to keep your body healthy and appearing ‘normal’ despite your attempt to dilute the THC metabolites in your system for the test. This means eating healthy and drinking an above average amount of water in the days or weeks preceding the test. Anecdotal evidence suggests supplementing with use of natural diuretics (coffee, cranberry juice, etc.). About 24 hours before the exam you can take a vitamin B complex supplement which will help bring the yellow color back to your urine (making it appear less diluted). It is also suggested that you supplement with creatine, as the absence of creatine metabolites is another way testing facilities monitor against dilution.

Pee: Don’t let the test be your first pee of the day! Try to urinate several times prior to the actual test. When you step into the restroom, catch your sample mid-stream as it will have the lowest concentration of metabolites.

There are red flags for a testing facility.

If you have a flagged sample, you will get more time before you have to take the drug test again. The employee was likely attempting to beat the test, and some companies know that a flagged sample indicates that. If any of the following properties are not in the appropriate range, your sample will be flagged.

– Temperature, specific gravity, pH, creatinine concentrations or appearance (color)


If you don’t have enough time to implement the dilution strategy described above, there are substances that you can add to your urine to make a false negative test result. Zinc and papain are the two primary urinary adulterants that have been proven to interfere with drug test results.

Zinc: Zinc is available as in powder form (zinc sulfate) or as an oral supplement available at any health store. An August 2011 study published in the Journal of Analytical Toxicology concluded that the use of zinc, both as a urinary adulterant and an oral supplement, is effective at subverting routine drug testing. The addition of zinc to a urinary sample was shown to cause reproducible false-negative results on a drug test. It is important to note the zinc likely interferes with the testing mechanism, rather than interacting with the drugs themselves.

The study goes on to state, ‘consumption of zinc supplements taken orally after light marijuana use can interfere with the detection of THC in urine samples for a 12-18 hour period.’ The study also concluded that the use of zinc as an oral supplement was undetectable by standard means. The study dose is 200mg of zinc orally (it’s important to note the test subject was a one-time smoker). For the full text, click here.

Papain: Papain is a biologically active substance derived from the papaya plant and can be found in granule or powder form. An August 2005 study published in the Journal of Analytical Toxicology concluded that ‘papain exerted a dose-dependent significant effect [decrease] on the concentration THC-COOH in a dose-dependent manner…’ that led to false-negative test results (when added to a urine sample).

There are last resort options that don’t involve the use of a drink if you are running out of time. Synthetic urine options, as well as bags that allow you to collect and excrete another person’s clean urine, are available. This may sound extreme, but it is the only way to avoid losing your job over the consumption of a harmless plant.

We highly recommend the Powdered Urine Kit from TestClear as it utilizes real human urine as opposed to synthetic ingredients that have a higher chance of raising red flags in the testing process. Another reason we love this Powdered Urine Kit is that it includes two air-activated heaters and a temperature strip to ensure the urine sample temperature tests within the acceptable range.

Detox Products

There are literally hundreds of detox products available. While they are all slightly different, nearly all of them will use one or more of the strategies discussed above. Look at the ingredient list and understand what you’re potentially consuming. Do they work? Yes (with the one caveat that you must purchase from a reputable company). The implications of a failed drug test can be devastating, and that’s why the only detox products we recommend are those sold by TestClear.

The correct detox product for you will depend on the type of drug test your taking and how much time you have before the test. For hair follicle tests, we suggest you start with the Old Style Aloe Toxin Rid Shampoo during the days leading up to the test and then apply the Zydot Ultra Clean Shampoo on the day of the drug test.

For urine tests with very short notice (i.e. 24 hours), we recommend the Mega Clean Cleansing Drink. If you have more than 24 hours before your drug test, we advise you to use the Toxin Rid product line from TestClear, which is available in 2, 3, 4, 5, and 10-day detox programs. You can also use the Toxin Rid detox program to pass a blood drug test. All of the Toxin Rid products come with a Money Back Guarantee, meaning they really stand behind their products. The other reason we like ordering from TestClear is that products can be shipped overnight—perfect for passing that last minute drug test.

Test at Home

Running out of time and can’t calm your nerves? Grab an at-home marijuana drug test kit. For less than $10 you can have peace of mind before taking the real exam. It’s a great way to see if the dilution strategy or detox program worked.

The True Cleanse

As we stated at the beginning of the article, abstinence is the only way to truly cleanse your body of all active THC and associated byproducts. Depending on your specific usage habits, it will take between 7 and 14 days for the active THC molecule to exit the body for those that consume regularly. Two weeks without cannabis?! Many people take periodic tolerance breaks (also known as T-breaks). Believe it or not, it’s possible to hit the reset button on your cannabis tolerance – when you resume, it will be like smoking for the very first time…again. When you resume use, remember to start slow i.e. smaller dosages than before the break.

We would like to reiterate that while two weeks is a sufficient time for most to rid their system of active THC and reset their tolerance, it does not mean you will pass a drug test! Regular cannabis users will have non-psychoactive THC metabolites in their system for up to 90 days. Abstinence is also the only way to rid your body of all THC metabolites – so if you don’t want any evidence of THC in your system, you will likely need to abstain for a significantly longer period than two weeks. Remember, drinking fluids doesn’t increase the shedding of metabolites; it simply dilutes the test sample.

What About CBD?

This article addresses the presence of THC in the body, but what about CBD? In case you are unfamiliar, CBD is the second most prevalent compound in cannabis – it’s non-psychoactive and provides a wide range of therapeutic applications. The interesting thing about drug tests is that they were only designed to test for the presence of THC in the system – if you recall, the drug tests look for a byproduct of THC, not CBD. That means that patients using CBD products derived from hemp, which contains less than 0.3% THC, should not test positive on a drug test (there is a single, unconfirmed study that found that CBD could be converted to THC by the digestive tract, but these findings have not been replicated and further studies have contradicted the proposed phenomenon of CBD to THC conversion).

There is a caveat we need to address, which is that some full-spectrum products could be concentrated so that the amount of THC exceeds that 0.3% figure. To show how this could happen, we did some basic math to replicate the concentration of a bottle of tincture.

If the sample of industrial hemp flower used to make the tincture was composed of 18%Cannabidiol and 3%Throat, the concentration of the extract needed to yield 500 grams ofCannabidiol would be about 8.33 percent. The theoretical amount of the starting material is about 0.3%.

In this example, the theoretical dose of our oil would be about 0.42 percent of the total amount. If you use your oral dose of cannabidiol in conjunction with other forms, such as Vaping or Dabbing, those trace amounts of THC may add up to become detectable in your system, causing you to risk failing a drug test. If you are worried about passing a drug test, it is best to look for options that have been tested by an independent laboratory and show their compliance with the rules, or they will be shown to not have any THC at all.
