How Long Does Kratom Stay In Your System

In the world of natural remedies, kratom has emerged as a captivating contender. Hailing from the lush forests of Southeast Asia, this botanical substance has garnered attention for its potential to provide an array of effects, from pain relief to mood enhancement.

But as kratom’s popularity surges, questions about its staying power in the human body have taken center stage.

How long does Kratom stay in someone’s system?

The duration for which kratom remains detectable in your system depends on various factors, including dosage, frequency of use, metabolism, and the type of drug test employed. 

Generally, Kratom’s active components, mitragynine and 7-hydroxymitragynine, have a half-life of around 24 hours. This means that after one day, half of the kratom’s compounds will have been eliminated from your body.

Complete clearance from your system might take around five to six days, assuming normal metabolism. Keep in mind that heavy or prolonged use of kratom could potentially extend the detection window. 

Factors like liver function, body fat percentage, hydration levels, and genetics can impact the clearance time. Understanding these variables can provide insight into the duration kratom might be detectable in your system.

Does Kratom Show Up on a Drug Test?

Kratom is known for its psychoactive and pain-relieving properties. As with many substances, various methods can be employed to detect the presence of kratom in the body. These methods include urine, blood, saliva, and hair tests. Each method has its own detection window and level of accuracy.

  • Urine Tests: Urine tests are one of the most common methods for detecting kratom and other substances in the body. Kratom’s alkaloids, such as mitragynine and 7-hydroxymitragynine, can be detected in urine.

    The detection window for kratom in urine is relatively short, typically ranging from one to seven days after use. However, frequent or heavy kratom users might have a longer detection window due to accumulation in the body.
  • Blood Tests: Blood tests can also detect kratom and its metabolites, offering a shorter detection window compared to urine tests. Kratom’s presence in blood is detectable for a shorter period, usually within 24 hours of use. This method is more suitable for detecting recent kratom consumption, such as in cases of suspected impairment or intoxication.
  • Saliva Tests: Saliva tests are less commonly used for kratom detection compared to urine and blood tests. Kratom’s presence in saliva can be detected within a few hours after use and typically remains detectable for up to two days. Saliva tests are often used in scenarios where recent use needs to be determined quickly.
  • Hair Tests: Hair tests offer a longer detection window for kratom compared to other methods. Kratom’s metabolites can be incorporated into hair follicles, allowing for detection for an extended period. 

Hair tests can identify kratom use for several months after consumption, making them suitable for assessing long-term or chronic use patterns.

Accuracy and Limitations of Drug Tests

The accuracy of these detection methods depends on various factors, including the sensitivity of the testing equipment and the expertise of the laboratory personnel. Generally, these methods are considered reliable in detecting kratom use, but there are some limitations to consider:

  • Cross-Reactivity: Some substances with structural similarities to kratom’s alkaloids might lead to false positive results. Laboratories typically employ specific tests to minimize such cross-reactivity.
  • Dosage and Frequency: Detection windows can vary based on factors such as the dosage and frequency of kratom use. Higher doses and more frequent use could lead to longer detection windows.
  • Individual Variability: Each individual’s metabolism and physiological characteristics can influence the detection window. Factors like age, weight, metabolism, and overall health can impact the time kratom remains detectable.

Hence, various methods can be used to detect kratom in the body, including urine, blood, saliva, and hair tests. Each method has its own detection window, which varies based on factors like the type of test and the individual’s use patterns.

While these methods are generally accurate, it’s important to consider their limitations and the potential for false positives. Detection methods play a crucial role in medical and forensic settings, helping to monitor kratom use and its potential implications for health and safety.

How is Kratom Metabolized in the Body?

Kratom (Mitragyna Speciosa) is a tropical tree native to Southeast Asia, and its leaves contain compounds known as alkaloids, including mitragynine and 7-hydroxymitragynine, which are responsible for its effects. 

The metabolism of kratom in the body involves several processes, primarily carried out by enzymes in the liver.

Here’s a general overview of how kratom is metabolized in the body:

  • Absorption: After consumption, kratom is absorbed through the gastrointestinal tract and enters the bloodstream.
  • Distribution: Kratom compounds are then distributed throughout the body, including the brain, where they interact with various receptors, including opioid receptors.
  • Liver Metabolism: The liver plays a significant role in metabolizing kratom compounds. Enzymes in the liver, particularly those of the cytochrome P450 family, are responsible for breaking down kratom alkaloids into different metabolites. This process is similar to how the liver metabolizes other drugs and substances.
  • Phase I Metabolism: Phase I metabolism involves oxidation, reduction, and hydrolysis reactions. Mitragynine, one of the primary alkaloids in kratom, is converted into several metabolites through these processes.
  • Phase II Metabolism: Phase II metabolism involves conjugation reactions, where the metabolites produced in Phase I are combined with certain molecules (e.g., glucuronic acid or sulfate) to make them more water-soluble. This enhances their excretion from the body.
  • Excretion: The metabolites formed through Phase I and Phase II metabolism are excreted from the body primarily through urine and, to a lesser extent, through feces.

It’s worth mentioning that individual variations in metabolism can affect how quickly kratom and its metabolites are cleared from the body. Factors such as genetics, liver health, and other medications being taken concurrently can influence kratom metabolism and its effects.

Factors Influencing Detection Time of Kratom

Let’s delve into the detailed exploration of the factors that can influence how long kratom stays in the system:

Dosage and Frequency of Use of Kratom

The amount of kratom consumed in a single dose and the frequency of use play a significant role in how long it remains detectable. Higher doses and more frequent use can lead to a buildup of kratom’s active compounds in the body, potentially extending its detection window.

Individual Metabolism and Genetics

Metabolism varies from person to person due to genetic factors, age, and overall health. Individuals with faster metabolism might process and eliminate kratom more rapidly, reducing its detection time compared to those with slower metabolism.

Body Mass and Composition

Body mass and composition influence how kratom is distributed and metabolized. Those with higher body fat percentages might retain kratom compounds for longer periods, as certain substances can be stored in fat cells.

Hydration Levels and Urine pH

Hydration can affect the concentration of kratom metabolites in urine. Well-hydrated individuals might have lower concentrations and shorter detection times compared to those who are dehydrated. 

Urine pH can also impact detection time, as more alkaline or acidic urine can affect the elimination rate of substances.

Co-administration with Other Substances

Using kratom in conjunction with other substances, such as medications, alcohol, or illicit drugs, can affect how long kratom stays in the system. Some medical substances might interact and influence the metabolism or elimination of kratom.

Kratom Strain and Preparation

Different kratom strains and preparation methods can contain varying levels of active compounds. Some strains might have higher concentrations of certain alkaloids that take longer to metabolize and eliminate, potentially affecting detection times.

Liver Function

The liver plays a crucial role in metabolizing and breaking down kratom compounds. Individuals with compromised liver function might experience altered metabolism, potentially extending the time kratom stays in the system.

Age and Health Status

Age and overall health can impact the efficiency of metabolic processes. Elderly individuals or those with certain health conditions might experience slower metabolism, leading to a longer detection window.

Detection Method

The method used to detect kratom, such as urine, blood, or hair testing, can influence the detection window. Different methods have varying sensitivities and can detect kratom or its metabolites for different lengths of time.

While these factors can influence the detection time of kratom, the exact duration can vary widely between individuals. Additionally, the legality of kratom and its detection may differ based on jurisdiction and the specific testing methods employed.

Tips for Faster Clearance of Kratom

Here are the tips to withdrawal kratom faster for your system:

  • Hydration: Drinking plenty of water can help flush out toxins from your system, including kratom metabolites. Adequate hydration supports your kidneys in their role of filtering and eliminating waste products.

  • Healthy Diet: Consuming a balanced and nutritious diet can provide your body with essential nutrients and support overall metabolic functions. Fiber-rich foods can help with digestion and waste elimination.
  • Time: The body’s natural detoxification processes take time. As you follow a healthy lifestyle, your body will naturally work to eliminate substances from your system.
  • Avoid Re-dosing: Cease kratom use during this period to prevent adding more of the substance to your system. This gives your body a chance to clear out what’s already present.
  • Rest and Sleep: A well-rested body is more efficient at performing its natural detoxification functions. Prioritize quality sleep.
  • Supportive Supplements: Some people suggest that certain supplements, such as those containing antioxidants (e.g., vitamin C) or compounds that support liver function (e.g., milk thistle), might help the body’s detoxification processes. However, scientific evidence for these claims is often limited.

It’s important to note that the rate at which kratom or any other substance is cleared from the body can vary widely depending on factors such as metabolism, frequency of use, dosage, and individual physiology. 


So, the duration that kratom stays in an individual’s system can vary based on a multitude of factors. It is clear that several variables, such as dosage, frequency of use, metabolism rate, and individual differences, play crucial roles in determining the retention time of kratom’s active compounds in the body.

Generally, complete clearance of the Kratom from the system takes around five to six days. However, the duration may be shorter for occasional users. It is important to note that the metabolites of kratom could potentially be detected in certain drug screenings, adding to the complexity of accurately estimating its presence.
