Will kratom be detected in a drug test?

Key takeaways

Standard drug screens tend to look for substances such as opiates, amphetamines, and cannabis, but kratom is not usually included unless a specific test is requested.
Specialised tests using techniques like mass spectrometry can detect kratom; however, these are rare and mainly used for legal or medical reasons.
How long kratom remains in our system depends on several factors, including our metabolism, how often we use it, and which strain we take.
The main alkaloids in kratom—mitragynine and 7-hydroxymitragynine—interact with opioid receptors, but generally won’t trigger a false positive for opiates in common tests.
Detection times vary depending on the type of test: urine screenings might pick up kratom for several days, while blood tests usually have a shorter window.
It’s important for us to be aware of both local laws and our workplace policies. Testing positive for kratom could affect our job, legal standing, and even our relationships.

For most of us, kratom isn’t picked up in routine drug tests, whether they're for job applications or regular workplace screenings. These tests typically check for drugs like cannabis, opiates, and amphetamines—not kratom.

However, there are specialised screenings that can identify kratom, but these are unusual and not part of standard testing. If we want to know when kratom might show up, it’s helpful to understand the exact type of test being used. Let’s break down the details.

Does kratom show up on a drug test?

Most routine drug screens do not detect kratom or its main alkaloids, mitragynine and 7-hydroxymitragynine. These tests are mainly designed to look for well-known controlled substances and usually overlook herbal products entirely. If kratom is going to be checked for, it’s only through specific tests requested for that purpose.

For reference, here are the drugs most standard workplace drug screens identify:

Opiates (like morphine and codeine)
Amphetamines
Cocaine
Cannabis (THC)
PCP
Some tests may also screen for benzodiazepines and barbiturates

Standard test panels

A typical 5-panel workplace test doesn’t include kratom. Most companies use these for employee screening, meaning natural products such as kratom go unnoticed.

Because of this, there’s a belief that kratom is “invisible” on drug tests. In reality, unless the test is specifically set up to find kratom, it won’t show up. These panels are designed to detect certain compounds and herbal substances like kratom are ignored unless there’s a special reason to include them.

Specialised testing

However, more advanced drug tests can specifically look for kratom or its metabolites. These can use highly accurate laboratory techniques like mass spectrometry and chromatography to identify them in urine, blood, or hair samples.

These specialist tests are mostly used in court cases, serious health investigations, or research. Kratom might be detectable in urine for up to a week, and in hair samples for around three months, but these tests are expensive and aren’t carried out in routine settings. For the majority of us being screened at work, standard drug tests won’t pick up kratom.

Mistaken identity: opiates

Kratom’s chemistry works differently to opioids and it doesn’t often cause a false positive result for opiates. The structure of kratom’s alkaloids doesn’t register with regular test kits. However, with outdated tests or in rare instances, mistakes could happen—though modern labs can clearly tell kratom and opioids apart.

The main compounds

The most active ingredients in kratom are mitragynine and 7-hydroxymitragynine. These interact with opioid receptors in the body, but their effects depend on the specific strain or mix. Some varieties are more relaxing, while others can feel energising.

If we’re worried about drug screening, knowing what’s in the kratom we use gives us more control.

Drug test thresholds

All drug tests have limits, or cut-off points, for what they report as a positive result. Kratom doesn’t cross these thresholds in the usual tests, so it goes undetected. If, however, a test is set up to search for kratom specifically, even small traces could be picked up. It’s always worth checking what type of screening is being used if we have any concerns.

How long does kratom remain in your system?

How long kratom stays in our system comes down to the amount we take, how often we use it, and our individual body chemistry. If we're facing possible drug tests—whether for work, travel, or something else—knowing this timeline helps us make better choices, avoid stress, and steer clear of any nasty surprises.

Kratom’s half-life can range anywhere between 3 and 24 hours, and those of us who use it regularly might find it lingers a bit longer. Most sources agree that kratom can be detected for roughly five to seven days, although certain testing methods might pick up traces beyond that period.

Urine testing for kratom

Kratom markers usually show up in urine between three and seven days for most people.
Larger or more frequent doses might be detectable for longer.
Staying hydrated and having a faster metabolism may shorten this window.
Standard urine tests might not spot small or occasional doses.

Urine testing is by far the most common way kratom is detected. Given its half-life—which can be as much as 39 hours—kratom tends to hang around in urine for less than a week. That’s why it pays to know our own usage patterns and general health when considering potential detection.

Detecting kratom in blood

Blood tests give a snapshot of current kratom levels in our body. On average, kratom remains detectable in blood for anything from two to nine days, but most people will clear it before then. If we only take kratom once or very rarely, a blood test is unlikely to show anything after a few days.

Blood tests aren’t typical for routine drug screening—they’re generally used in medical or legal cases where recent use matters most. For frequent users or those who take high doses, kratom can linger in the blood for longer.

Kratom detection in hair tests

Hair tests can detect kratom use up to 90 days after we’ve taken it, as its alkaloids settle in the hair as it grows. It takes a while for kratom to move from the bloodstream into the hair follicle, so hair testing won’t show up recent use but can reveal a pattern of consumption.

Hair testing for kratom isn’t standard; labs usually reserve these tests for other substances. Still, if it’s used, it offers a much longer detection window.

Saliva testing

Saliva tests offer a simple, non-invasive way to detect recent kratom use—often within hours of consumption. The detection window with saliva is short, usually just one or two days.

Some clinics and workplaces now use saliva drug tests for speed and ease, but results depend almost entirely on how recently we’ve taken kratom.

Key Factors Affecting Kratom Detection

When it comes to testing for kratom, there’s no one-size-fits-all answer. How long kratom can be detected in our bodies depends on a range of variables, including our personal biology, lifestyle, and even the specific kratom product we use. Understanding these factors helps us manage our use more effectively and minimises the risk of testing positive if we’re subject to a drug screening.

Checklist: Why Our Biology Plays a Vital Role in Kratom Metabolism

Age, body weight, and individual genetic make-up all influence how efficiently we process kratom.
Liver health is crucial — any issues with liver function can either slow down or speed up how quickly kratom leaves the system.
Our diet and fitness levels will shift our metabolic rate up or down.
Genetic factors and the presence of other health conditions can also have an impact.
Mixing kratom with alcohol or other medications will affect how long it remains detectable.

Patterns of Use

The amount and frequency at which we take kratom are major factors in how long it may show up on a drug test. If we use it daily or in higher amounts, our bodies will store kratom metabolites for a longer period. Occasional or low-dose users are likely to process it much more quickly.

For instance, if we only take kratom once, it could clear from our system in a couple of days. However, frequent use means metabolites can linger, leading to a longer detection window. The more often we use kratom, the more it accumulates, and the harder it is for our bodies to expel it.

To really understand our own level of risk—especially if there’s a chance of being tested—we need to keep a close eye on our kratom consumption.

Our Body’s Role

Metabolism is at the heart of how quickly kratom gets processed. Those of us with faster metabolisms—often younger or more active people—are likely to eliminate kratom more rapidly, reducing the time it is detectable.

Age, overall health, and body composition can all slow things down. If we have a higher body fat percentage, kratom metabolites may get stored for longer, as some compounds settle in fat cells before being broken down.

Most importantly, good liver function is essential. If our liver is under strain, kratom will stay in our system for longer. Genetics can also introduce variation; everyone’s body processes substances differently.

The Type of Kratom Matters

Not all kratom products are equal. Different strains—like red, green, or white vein—break down in the body at different rates. Products with higher potency or those made from extracts can stay in our system longer compared to standard kratom leaf.

How we consume kratom makes a difference too. For example, brewing kratom as a tea could mean it’s processed quicker than taking it in capsule form, since liquids are absorbed into the bloodstream faster.

By knowing the specific strain and strength of kratom we’re using, we can make a better guess as to how long it might be detectable if we ever have to take a test.

Understanding how kratom is processed by the body

Getting to grips with how our bodies metabolise kratom lets us understand how long it might remain detectable, and explains why testing results can vary from one person to another.

What happens to kratom in our system?

When we consume kratom, it first encounters our stomach acids and digestive enzymes. The most active natural compounds – mitragynine and 7-hydroxy mitragynine – then make their way into our bloodstream.

Our liver does most of the heavy lifting from here. Special enzymes, particularly CYP3A4, break these compounds down into metabolites that the body can process. These metabolites are then carried to the kidneys and are removed from the body through urine.

How quickly this all happens is influenced by several factors, including our genetics, age, overall health, and what medications we might be taking. For instance, anyone with liver issues or those on certain prescription medicines may find that kratom remains in their system for longer.

On the other hand, healthy adults with faster metabolisms will process kratom more quickly. Typically, kratom’s half-life is about a day, but if we use it frequently or in larger amounts, remnants can still be detected for several more days.

Kratom metabolites and detection times

Metabolite	Tested in	Typical detection window
Mitragynine	Urine, blood	1–9 days (urine), 1–3 days (blood)
7-hydroxy mitragynine	Urine, saliva	1–9 days (urine), 1–4 days (saliva)

Standard drug screenings won’t look for kratom or its specific metabolites, but specialised lab tests such as liquid chromatography–mass spectrometry (LC-MS) can detect mitragynine and its metabolites in blood, urine, or saliva.

Urine testing is most frequently used, and could pick up kratom use for up to 9 days – though for most people, this window is a bit shorter. Saliva testing is usually less intrusive and spots kratom use for around four days.

It’s also possible to test hair samples, which may reveal kratom use up to 90 days afterwards. However, this method is rare due to high costs and limited research. By knowing which metabolites show up where, we can make informed choices – especially if we’re concerned about upcoming drug screenings.

Kratom metabolites stay in hair for longer, whereas they’re eliminated more quickly from saliva and blood. This is useful for anyone wanting to avoid surprises on a drug test.

Why metabolism varies from person to person

All of us process substances at slightly different rates. Factors such as age, liver health, body mass, and hydration levels play a role in how speedily kratom is metabolised.

If we use kratom heavily and regularly, detection windows are usually longer, as the substance can build up in our body fat. Infrequent users generally clear kratom from their system more rapidly – especially if they maintain a healthy, active lifestyle.

Taking higher doses or having a higher body mass index can extend the time kratom lingers within us, particularly with daily or frequent use.

The importance of understanding metabolism

Being aware of how our bodies process kratom helps us gauge the likelihood of it showing up on a drug test. The time it stays detectable depends as much on us as on kratom itself.

Tests may use saliva, urine, blood, or even hair samples, and the detection period can vary widely. With a typical half-life of around 24 hours, kratom often leaves the system within a few days, but various factors might extend this window.

Is kratom considered a drug? Our honest take

Kratom sits in a complicated space, straddling the line between a natural supplement and what many would call a drug. Originating from Southeast Asia, it’s been part of traditional wellness remedies for generations—mostly used to tackle pain, fatigue and sometimes for a mood lift. Recently, the conversation has shifted: some people herald kratom as a natural solution, while others flag up the risks and call for tighter controls.

The classification debate

We often hear kratom likened to familiar drinks such as coffee or tea, thanks to its plant origin. At the same time, the effects—ranging from mild pain relief to feelings of euphoria—make others see it as a drug. The controversy is fuelled by the fact that kratom isn’t officially regulated by food and drug authorities, especially in countries like the UK where lawmakers have banned its sale and possession since 2016. Across Europe and the US, the legal picture remains varied, so it’s crucial that we always check local rules before considering kratom for ourselves.

The big challenge for authorities is striking the right balance between keeping people safe and respecting the rights and traditions of those who use kratom. The ongoing debates and constant review of its legal status show just how unsettled its place in our society still is.

What’s it like to use kratom?

People turn to kratom for lots of reasons: some want relief from aches and pains, others crave an energy boost, and there are those looking for support through opioid withdrawal. Depending on the amount and format—be it tea, capsules, or raw leaves—some of us might notice a subtle mood lift, while others experience a stronger sense of euphoria.

We all react differently, though. A few of us may feel more focused or relaxed, while others report side effects like nausea or uneasiness. There’s also the risk of overdoing it; enjoying its effects a little too much can lead to taking more than intended. The key is to carefully observe how our own bodies respond and to keep a close eye on the amount we consume.

Personal tolerance can vary widely, meaning what’s comfortable for one person could feel quite different for someone else.

Weighing up the risks

Kratom isn’t risk-free. Some users find themselves needing more to get the same effect, or struggle to cut back—clear warning signs that dependence may be developing. Withdrawal symptoms, including muscle aches and irritability, do happen for some. The dangers become more pronounced when kratom is taken in large quantities or mixed with other substances.

Being responsible means starting with small amounts, taking regular breaks, and watching out for any changes in our mood or wellbeing. We also need to remember that kratom can remain in the system for up to a week, and its effects may last several hours. The way we take it—brewed, chewed, or ingested—can also change both its power and its potential for addiction.

The Real-World Impact of Testing Positive

Receiving a positive result from a kratom drug test can turn our lives upside down in ways we might not see coming—from our careers to legal standing, and even our closest relationships. Armed with the right knowledge, we can make more informed choices and sidestep avoidable issues.

Our Working Lives

Testing positive for kratom could put our jobs at risk, particularly if we work in fields like healthcare, transport, or anywhere safety is taken very seriously. Some employers consider kratom high-risk—even if it remains legal in parts of the UK—and have strict policies to match.

At many companies, drug policies are spelled out clearly, sometimes with kratom listed as a substance we’re not allowed to use. A positive result can lead to disciplinary action, dismissal, or closer supervision. For those of us who need professional licences—like lorry drivers or nurses—a test result like this could block us from getting or renewing those credentials.

If we're in a workplace that conducts post-incident drug screenings, a positive test for kratom might mean extra investigations or further testing, which can make working life much more stressful. It's vital for us to understand our employer’s drug policy, as attitudes toward kratom aren’t the same everywhere. Still, losing opportunities or our entire job is a genuine risk.

Legal Considerations

Kratom’s legal status in the UK is complex and ever-changing. Currently, it’s banned under national law and is classified under the Psychoactive Substances Act. If we test positive in an area where kratom is illegal, we could face fines, arrest, or other legal repercussions. The courts might treat kratom just like any controlled drug, especially if we’re already under court orders to avoid substances or are on probation.

It's also possible for kratom to produce a false positive for other substances, landing us in more hot water and adding extra complications.

We need to get familiar with the legislation in our area, so we aren’t caught out or exposed to unexpected risks.

Our Personal Relationships

Testing positive for kratom doesn’t just affect the official parts of our lives—it can put a strain on our relationships too. Those closest to us who might not understand kratom could worry or judge, leading to tension at home or among friends.

Social stigma is very real. Drug use can be seen as a sign of poor judgement or dependency, and whispers or gossip can leave us feeling isolated. On top of this, the stress of a positive result is genuinely heavy—we may feel shame, anxiety, or find ourselves worrying what others will think.

Opening up honest conversations with our loved ones and focusing on clear, open communication can help ease this pressure and make a difficult situation more manageable.

Conclusion

So, does kratom show up on a drug test? Generally, standard workplace drug tests will not pick up kratom, as most do not screen for it. However, there are specific laboratory tests that can detect its presence, but these are rarely used. How long kratom stays in our system will vary depending on factors like our dose, body chemistry, and how often we take it.

It’s important to keep in mind that the real concern may come from unannounced drug tests at work or when travelling to countries with stricter regulations. We should always double-check the laws in our area or any destination before taking kratom.

Many of us consider kratom for pain relief, mood improvement, or as a way to come off other substances. It works for some people, while it isn’t the answer for everyone. We should be honest about our reasons and make informed choices—whether that means giving it a try or deciding to steer clear.
