Because kratom remains unregulated by the FDA, we want to point out that although this article contains many points regarding the use of kratom, they should only be used for informational purposes, not medical advice.
Kratom is not intended to diagnose, treat, cure, or prevent any disease or condition. Make sure to speak to a physician if you have questions before using kratom.
Kratom is a plant that provides feelings of relaxation, focus, or energization. Some companies are now testing for it in a pre-employment drug test, as well as screening for it with random drug test schedules and in the case of accidents on the job. It is important to answer the question of how long does kratom stays in your system.
All substances are metabolized by the body. That is true whether it's kratom, alcohol, or even multivitamins that one might take every day. The metabolization process determines how long kratom will stay in your system to some extent.
After you take kratom, whether you do so in the form of a capsule, liquid, whole leaf, or powder, it enters your body and spreads through your bloodstream. Once ingested, the mitragynine and other compounds remain active for around an hour to an hour and a half with average doses.1 After that point, the liver begins to filter these from the blood, and then the body excretes them through the urine.
Does Kratom Show Up in a Drug Test?
The short answer to whether kratom will show up in a drug test is "maybe." This factor depends on the test in question. For instance, a standard five-panel drug test will not generally show kratom simply because these tests are not designed for that purpose. However, tests that check for blood mitragynine concentration and urine liquid chromatography drug test processes will show kratom use.
How Long Does Kratom Stay in Your System?
Kratom is only active in the body for a matter of hours. However, it can be detected for longer periods.
Blood testing is a very accurate type of drug test, but the results are very short-lived. Kratom metabolites will show up in blood tests, particularly if you regularly take large doses. However, it will only show up for a matter of a few days for those who use it heavily or very regularly. Kratom will stay in your system for less time if you take small doses or only use kratom occasionally.
You may ask yourself how long will kratom stay in your system, in your urine specifically? Metabolites can be detected in the urine for a week or longer. However, note that only some urine tests are currently capable of testing for kratom.
Hair and Saliva
Currently, there is no evidence that kratom shows up in a hair drug test and it is unlikely that kratom metabolites could do so. However, kratom can show up in a saliva test, although this form of testing is not currently used to check for kratom use in the United States.
The Detection Window of Kratom
The detection window of kratom varies from situation to situation, person to person, and test to test. Many factors affect it, including the dose size, how often you take it, and the type of test being performed. The window can vary from a few hours with blood testing to over a week with urine testing.
Understanding the answer to the question of how long kratom will stay in your system requires that you know a bit more about how it behaves in the body. The kratom half-life varies from metabolite to metabolite, but also by how long you've used it and how large your doses are. A half-life is the amount of time required for the body to eliminate 50% of the metabolites.
For instance, in someone who uses kratom frequently and takes large doses, the half-life of kratom is around twenty-four hours.2 However, those who use it less frequently and take smaller doses have a kratom half-life of just three and a half hours. Some metabolites have a half-life of under three hours. As such, the answer to how long will kratom stays in your system is very personal.
Critical Factors That Affect Kratom's Timeline
As mentioned, how long kratom stays in your system varies from person to person. So, what are the most important mitigating factors? Let's take a look:
Your age plays a significant role. As we age, our bodies' processes slow down, so kratom will stay in your system longer the older you are.
Body Mass Index
The higher your body mass index, the longer kratom will stay in your system since these metabolites are fat-soluble.
Genetic Metabolism Variables
Everyone's metabolic process is unique and variables within your system will affect how long will kratom stay in your system.
High-fat meals can absorb more of kratom's chemical compounds and affect the metabolic process.
Because kratom metabolites are excreted in the urine, better hydration means more urination, which leads to faster elimination from the body.
Frequency of Use
The more often you use it, the longer kratom stays in your system.
Larger doses, particularly when taken frequently, will stay in your system longer.
The Legality of Kratom in the United States
Currently, kratom is legal in many states in the US. However, it is not legal in a few. These include Alabama, Wisconsin, Vermont, Tennessee, Indiana, and Arkansas. Kratom is legal but regulated in most other states.
Perhaps the most important type of regulation is the Kratom Consumer Protection Act or KCPA. This act protects kratom users, makes it illegal to sell it to anyone under eighteen, and puts significant restrictions on retailers that offer kratom for sale to ensure quality, safety, and purity. Utah, Georgia, Arizona, and Oregon have passed versions of the KCPA.
Kratom legality is fluid, though, and many states have KCPA-like legislation in the works, and it is hoped that kratom will become fully legal in all states shortly.
Ultimately, the length of time that kratom will stay in your system varies from person to person. Given the legality of kratom, it is important to know the laws in your state. However, even in states where kratom is illegal, urinalysis, blood drug test options, and other tests for kratom specifically are rare.
