Kratom, also known as Mitragyna speciosa, has seen growing popularity in the U.S. over the past decade. People use it for various reasons—energy, mood support, pain relief, and more. But as its use becomes more common, one big question keeps coming up:
Does kratom show up in a urine test?
Let’s break this down based on what I’ve seen studying and working with kratom. Whether you’re new to kratom or a regular user, this post will help you understand how it interacts with drug testing.
How Do Urine Tests Work?
Standard urine drug tests screen for specific substances like opioids, THC, cocaine, and amphetamines. These tests don’t look for kratom by default.
So, does kratom show up on a drug test?
No, not on a standard 5-panel test used by most employers.
That said, things get more complex when advanced panels or targeted testing are involved.
What Type of Test Can Detect Kratom?
Kratom contains two primary alkaloids: mitragynine and 7-hydroxymitragynine. Standard drug panels don’t test for these. However, specialty or extended 10-panel drug tests can detect kratom—but only if the tester is specifically looking for it.
Labs need to use advanced testing methods like LC-MS (Liquid Chromatography-Mass Spectrometry) or GC-MS (Gas Chromatography-Mass Spectrometry) to detect mitragynine accurately. These methods are costly and rare in routine employment testing.
So if you’re applying for a regular job, a kratom drug test isn’t likely unless it’s specifically requested.
How Long Does Kratom Stay in Your System?
Let’s get to a common concern:
How Long Does Kratom Stay in Your System?
On average, mitragynine has a half-life of around 24 hours, based on available data. That means it takes about 5–6 days for kratom to leave your system entirely.
Here’s a rough guide for kratom detection time:
- Occasional users: 1–3 days
- Frequent users: Up to 7 days
- Heavy, daily users: Possibly up to 10 days or longer
These are estimates, not guarantees. Every body is different.
Factors That Affect Kratom Detection Time
Kratom doesn’t behave the same for everyone. Here are some key factors that influence how long it stays detectable:
- Serving Amount– Larger amounts may remain in the system for a longer time..
- Frequency– Daily use builds up more alkaloids in your system.
- Metabolism– Fast metabolism may process kratom faster.
- Age and weight– Older users or those with higher body fat may retain kratom longer.
- Hydration and diet– Drinking more water can help flush metabolites.
If you’re concerned about kratom drug test results, these variables matter a lot.
Will Kratom Make You Fail a Urine Test?
Here’s the honest answer:
Kratom won’t cause you to fail a standard urine test for opioids or other common drugs.
It’s not chemically the same as opiates. However, false positives are possible—especially if you’re taking other medications. Some users have reported false positives for methadone or other substances, although this is rare.
To be safe, if you’re using kratom and expecting a drug test, disclose it to the testing facility or your employer in advance, especially if it’s for medical reasons.
What About the Legal Side?
Kratom is legal at the federal level, but some U.S. states and counties have banned it. Always check local laws before using.
As of now, states like Alabama, Indiana, and Wisconsin have bans. Others may have restrictions or pending legislation.
Even in legal states, some employers still frown upon its use, especially in safety-sensitive jobs. So make sure you’re informed about your workplace policies.

Tips for Responsible Kratom Use
If you’re using kratom and want to be cautious with drug testing, here’s what I recommend:
- Know your source– Only buy lab-tested kratom from trusted vendors.
- Use in moderation– Less is more with kratom. Smaller amounts are easier on your system.
- Stay informed– Monitor changing laws and workplace rules.
- Stay hydrated– Helps with quicker metabolism and shorter detection time.
Responsible use not only reduces health risks but also lowers the chance of issues during employment screenings.
Final Thoughts: Should You Be Worried?
So—does kratom show up in a urine test?
Not unless someone is specifically testing for it.
If you’re a casual or moderate kratom user, you’re unlikely to be flagged during a typical 5- or 10-panel test. That said, kratom detection time varies, and extended panels exist.
Know your rights. Use kratom responsibly. And stay ahead of changing laws and policies.
