For any pot user, nothing is as dreadful as a drug test. Thus, how long does marijuana stay in your system becomes a very important question to which you surely want to know the answer? But don’t worry you don’t have to bring out your calculator to do the math because we are going to do that for you.

Marijuana is a drug that many people widely use. However, the drug does leave traces in the blood, urine, hair, and saliva. Fearing this, people often wonder how long does THC take to get out of your system. To understand the answer to this, we need to know the elements of the drug first. So, without wasting further time, let us start.

How Does the THC Metabolism Work?

When you consume drugs, it circulates in the body. Slowly, it starts showing its effects. How you consume THC determines how it’s finding its way into your body. So, your consumption method is important to the THC’s route. The drug reaches the blood and brain starting from the lungs. A little bit lower, you can read, how long weed stay in your blood system and other parts of your body.

But it undergoes a tough route in the intestines and liver. The liver has a high number of enzymes. It then metabolizes the drug. The process is called the first stage of metabolism. In addition, this process can occur in other parts like the brain.

Stage 1

Stage 1 includes the production of 11-OH-THC. In simple words, the process involves oxidation and hydroxylation. During phase 1, enzymes fuse with cannabinoids. This leads to hydroxylation. It adds hydrogen and oxygen to the structure. This is how THC undergoes changes and creates 11-OH-THC. The active metabolite has sedative and psychoactive effects.

Meanwhile, THC-COOH gets inactive. It prevents their ability to combine with cannabinoid receptors. This acts as a compound that has no medicinal value. On the other hand, 11-OH-THC gets active. It does have the ability to bind. But, as the current state of THC-COOH is not active, it becomes vital during urine tests. Also, you can store it for a month and use it to trace drugs in the urine.

Stage 2

In this second phase, the body wants to get THC out of your system fast.  The enzymes are the ones that do the task. It does so by combining THC-COOH with glucuronide. The process includes enzymes known as UGT enzymes. Once the combination between glucuronide and THC-COOH is done, it changes into one molecule.

The new molecule is THC-COOH-glucuronide molecule. It becomes a metabolite and starts to exit the body. The metabolite leaving the body is the last stage which happens through urine or feces.

A majority of the drugs exit the system within 3 to 5 days. However, the remaining drugs fuse with the tissues in the body. They gradually leave the body within a couple of days. It is this process that makes THC traceable after many weeks of consumption.

How Long Does It Take Weed to Leave System?

THC is a drug that makes you high. In this case, you should know the time it will take for the drug to exit the system in a lab. If you have the same question, “ how long weed stay in the system”, read on.

You can trace marijuana in various body parts. For example, you can detect them in saliva, hair, urine, and blood. Every body part has a particular detection time frame. This depends on the consumption amount or frequency of use. Once you consume THC, you can trace it within 24 hours to a month.

What Factors Impact the Detection Times for Weed

Many things can impact or change the detection time to some extent. How much you are using pot, how often, and even the way you are using it can lengthen the detection window.

And a precise idea about how long it will take for your body to purge all the impurities out of the system can help decide if you want to detox naturally or if you would need a detox product.

Below we will discuss factors that impact how long weed stays in the system. They are as follows:

How Much You Are Consuming Each Time

If you consume a lot of THC, your body will struggle and take a lot of time to eliminate it. Breaking down the metabolites and exiting the system will take longer. In addition, you also need to consider the potency of the drug. This is because there are some stronger types of marijuana as well.

The Method You Are Using for Ingestion Cannabis

How you consume the drug can determine how long the metabolites stay in the body. Some reports suggest vaping and smoking cannabis offer instant effects. If you choose to smoke or vape, the THC will exit your system faster.  When you consume cannabis edibles, you may not pay attention to how much you eat. Edibles stay in the system for a long and take time to break down and exit. This makes the drug last longer in the body.

Your Genetics

Another factor that determines how long drugs stay in the body is genetics. Some enzyme variants help in the faster elimination of drugs in some individuals. The inherited characteristic is enzyme concentration. So, if you are lucky with great genetics then it is possible to flush out drug residues faster than other people.

How Often Do You Take Marijuana?

The more you consume the drug, the longer it is traceable in the system. Interestingly, the consumption frequency and duration can impact how long the drug remains in the body. Heavy drug users tend to retain metabolites in the system for longer. However, the case is the opposite for occasional users. The detection time frame for a beginner consuming drug initially is 3 days. Those who use marijuana daily have a detection time frame of over a month.

Also, is it seen in many studies that people who are using cannabis for a long time in a heavy amount tend to test positive even when they have stopped using it for a month or so?

The Percentage of Body Fat

The next factor that determines how long THC stays in the system is body fat. The thing with THC is that it is fat-soluble. This means that THC can combine with fat cells. This makes them stay longer in body system.

Individuals with a higher body fat eliminate marijuana slowly. On the other hand, individuals with lower body fat can eliminate marijuana much faster. In addition, gender, as well as age too, can be factors.

Your Metabolism Rate

Drugs exit the body by normal functions. They include urine or feces. A person that has a faster metabolism will eliminate drugs faster. On the other hand, a person with a slower metabolism will eliminate drugs slower. This means the detection time frame is less if you have a good metabolism.

Types Of Drug Tests

The kind of drug testing you do also determines how long THC stays in your system. For instance, blood tests can detect drugs hardly for 3-4 hours since traces of pot stay in blood for a short while. But urine tests can trace drug use for over a month. Besides, saliva tests can detect drugs only for 24 hours of consumption. However, the most powerful one of these is the hair drug test. They can detect for over 90 days.


When you don’t have enough water in the system, the THC concentrations are high. But drinking tons of water won’t help you pass a test. Drinking water or fluids in large amounts just before the drug test can dilute your urine. If you do so, they will probably ask you to get a retest done. You have to drink just enough water to flush out toxins. You cannot let the body dry out.
