It is very important for everyone to detox from time to time, whether there is a habit of smoking weed or not. However, if you are one of those marijuana smokers that have to be interviewed for a job and you know you have smoked weed and the potential employer is asking for a drug test, then you have to flush the weed from your system. This is especially true if you really want to land that job. But, once the potential employer asks for a drug test, you don't have to be discouraged. There are things you can do to pass a drug test.

What is a Cannabis Detox?

Before we discuss the journey cannabinoids take within the body and effective ways to remove them naturally, let’s break down the meaning of cannabis detox. A detox is when a user abstains from consuming marijuana in order to remove any trace of the substance from the body.

During a cannabis detox, users are attempting to remove the intoxicating THC compounds and their metabolites from the body to avoid failing a pot drug test. For chronic and heavy users, however, a detox won’t be a walk in the park. Users may experience some mild withdrawal effects including:

  • Anxiety
  • Irritability
  • Depression
  • Loss of appetite
  • Headaches
  • Insomnia

Many of these “withdrawal symptoms” may be more noticeable due to the absence of weed, which can help reduce the discomfort associated with these side effects. Learn more about withdrawal symptoms and cannabis use disorder here.

Abstaining from cannabis is the only way to completely cleanse marijuana compounds from your body. Ideally, you want to abstain from marijuana for anywhere from one to three months to be sure there are no traces of cannabinoids in your system.

Not everyone has the luxury of having plenty of time to do a full marijuana cleanse. Even then, avoid cheating during a drug screening such as using synthetic urine because if you’re caught, you will definitely not get the job, not to mention it’s legally dubious.

THC Levels

THC remains in your system for about one week and if you are a heavy marijuana smoker, you may need more time to flush your system. It is better to know beforehand what should be done to get rid of THC metabolites. If you don't have knowledge of what to do in advance, then you may consider turning down the job, but you don't have to do so.

When inhaled, THC goes through the lungs, to the heart, and travels through the body to various cannabinoid receptors (CB1 and CB2). CB1 receptors can be found in the brain and central nervous system, while CB2 receptors are primarily located in the immune system and spleen.

When consumed as an edible, THC goes into the bloodstream through the stomach and intestinal walls where it goes right to the liver. A large amount of THC is metabolized and then circulated throughout the body and into the brain.

THC metabolites

The screenings done during a drug test involves urine tests for THC metabolites, but tests can also detect metabolites in hair, saliva, and blood. The question is what are these THC metabolites? Metabolites are the side effects or residue of marijuana once the body has already processed the THC. So, the person doing the testing is going to look for THC metabolites or THC-COOH presence in your system.

When THC circulates throughout the bloodstream, some of it passes through the liver and becomes metabolized into many different metabolites including THC-COOH and 11-OH-THC. These metabolites are inactive forms of THC that can stay in the body longer than active THC.

Preparing for the Drug Test

To ensure that you are prepared for the drug test, you have to know how much THC metabolites you have in your system. You also have to be aware of the accepted testing levels for a drug screening. If you are like other marijuana smokers, you have to be aware of how long you have had the marijuana in your system. It is not that complicated.

Generally, urine tests are performed due to their ability to detect cannabinoid metabolites for a longer amount of time. Some chronic marijuana users can fail a urine drug test months after their last consumption.

In urine tests, the THC-COOH cutoff point can range between 15 nanograms per milliliter (ng/mL) to 100 ng/mL. More often than not, you’ll encounter a urine test with a 50 ng/mL cutoff. You’d fail the test if you had more than 50 ng/mL in your sample.

Blood tests are also drug screening methods, albeit, less common than urine tests. Blood tests can detect marijuana use only a few hours after consumption.

Saliva drug tests have an even more narrow detection window than blood tests. Oral fluid can contain THC in occasional users between one to three days after use. Chronic users could retain cannabinoids in their saliva up to 29 days after use.

Hair tests can detect THC and THC-COOH up to 90 days after use, but these drug tests are considered the most inaccurate of the bunch due to their ability to produce false positives.

The Time Period

As mentioned before, THC metabolites remain for a week, in most cases. For that reason, every seven days, the THC metabolites that are in your body is reduced by fifty percent. Therefore, the assumption is that you won't get rid of one hundred percent of the THC metabolites until about 2 to 4 weeks since one week is half the life of the metabolites. It is significant to be aware that it will depend on how much marijuana you have smoked. Your weight has to also be taken into consideration.

Ultimately, the length of time THC remains in your body depends on your metabolism, frequency of use, the amount used, and genetics. Higher doses and frequent consumption, as well as high body fat, can keep THC in your system for longer and make it harder for you to quickly get rid of it.

The Characteristics

Due to the fat-soluble characteristic of THC, it is stored in your fat cells as soon as the THC metabolites are released in your bloodstream. This is not beneficial to the purpose of passing a drug test. Marijuana smokers all across the nation have passed drug tests with a low level of THC metabolites still in their system. Your THC levels only have to be below the threshold of 50 mg/mL. And as long as your drug test comes back negative, you are in the clear. Now, how do marijuana smokers pass drug tests?

Passing the Drug Test

The first thing is the dilution of your urine, but you have to cover this up so that the drug tester does not know that your urine has been diluted by you. How do you do this? Drink water mixed with apple cider vinegar to dilute the urine and flush your system. But, you should start drinking up to four liters of water, at least 3 weeks prior to the drug test. Drink more water an hour and a half before taking the test.

Things to Know

Creatine and Vitamin B are also two supplements that work together to get your urine just right so there is no suspicion that you are trying too hard to clean your urine. Take about 100 mg of Vitamin B12 or Vitamin B2 and creatine supplements several hours prior to the test. Do not exercise the day before the test because this will spike up the level of your THC metabolites. When you get ready to pass urine in the cup, wait until the middle of passing urine before you catch it in the cup. The first and last portion of the urine stream has the highest level of metabolites.

Should You Trust Home Drug Tests?

If you’re worried you might fail a drug screening test, you could try one of many home drug tests to determine your current THC metabolite levels. Home drug tests are fairly accurate.

Make sure you consider your home drug test’s sensitivity for THC metabolites. Keep in mind, factors such as temperature and time can affect the drug test results meaning you could get inaccurate results.

Home and lab drug screening methods use a method called an immunoassay (IA) panel based on a standard created by the federal Substance Abuse and Mental Health Services Administration.

Drug tests differ in sensitivity. Generally, more expensive drug tests are more precise and are more sensitive to lower cutoff levels. Low cutoff levels detect even the smallest amounts of cannabis compounds in your system.

How to Get Cannabis Out of Your Blood

To get cannabis out of your blood it is helpful to use a detox. A marijuana detox can cleanse the body and lower levels of THC in the blood stream.

Do Detox Remedies Work?

If you’ve searched around for fast ways to get weed out of your system, you might have run across a variety of marijuana detoxes that claim to flush your body of any detectable THC. You can find kits that include capsules, drinks, chewable tablets, shampoos, and mouthwashes to handle a variety of tests. These kits are, by no means, a surefire way to pass a drug test fast.

Keep in mind, consuming these marijuana detoxes can affect the look and chemical composition of your urine and make the screener suspicious. Detox teas and drinks can help “flush” out the THC simply by making you urinate more often than usual.

Nicolas Rossetti, manager of clinical services of Mobile Health in New York City, told Healthline that the “flushing of the kidneys can lower the specific gravity or density of the urine and a low specific gravity indicates contamination on the test, and the specimen could be discounted.”

Detox teas and cleanses have the ability to affect the concentration of creatine in the urine. Screening tests detect creatine levels, so abnormal levels can give screeners pause. While you won’t fail a drug test, screeners might ask you to take the test again.

Home remedies that involve cranberry juice, vinegar, niacin, baking soda, alcohol, or even bleach are not recommended. These detox methods are more myth than truth. In reality, there is no immediate fix for getting rid of cannabis.

Following these myths can not only make you very sick, but also cause serious injury and side effects including vomiting when consuming baking soda, as well as pain and burns from drinking bleach.

Bentonite clay, however, is one of the most popular methods to perform a marijuana detox. Bentonite clay is made from volcanic ash and is thought to absorb toxins and other contaminants in the body, albeit, more research is needed.
