How Long Does Kratom Stay In The System?

Last Updated: April 30, 2020

As Mitragyna speciosa is a drug of concern, passing a drug test for kratom for many may be challenging. This article aims to highlight different types of kratom drug testing, what test is the most widely used, and how long the substance stays in one’s system.

How Long Does Kratom Stay In One’s System?

There is no much evidence and clinical research on how long Mitragyna speciosa products stay in the human body after consumption. The limited data shows that kratom half-life is about 24 hours. That means that 50% of active ingredients such as 7-hydroxymitragynine and mitragynine are eliminated in one day. Full disposal can take two days.

Taking the substance with alcohol-containing products increases a chance of negative effects of kratom because firstly organism processes alcohol, not Mitragyna speciosa alkaloids.

Does Kratom Show Up On A Drug Test?

Usual drug tests made by the Substance Abuse and Mental Health Services Administration can’t detect Mitragyna speciosa traces, because they intend to check only five types of drugs: opiates, amphetamines, cocaine, cannabinoids, and PCP. Only specific kratom drug tests should be used for examination.

How Long Can Kratom Be Detected In Urine?

Urinalysis is the most common method to identify this herbal supplement presence in the system. The kratom urine test can detect specific alkaloids and show a positive result, even in a week after the consumption. For the average user, the test can detect trace amounts for five days after the usage. To get a negative result, it is better to avoid administering the herbal supplement for two weeks or abstain from its consumption at all.

How Long Can Mitragyna Speciosa Be Detected In Blood?

This type of kratom testing is used to ascertain if someone has taken the supplement and how much, as the substance can easily be recognized in blood. A blood kratom test is uncommon for substance detection. However, it should be taken during the first 24 hours of injection for more accurate results. Intoxication levels show 100 ng/ml or higher. For stating an overdose via blood screening, the level of mitragynine concentration in plasma frequently exceeds 300 ng/ml. Since blood screening has a short detection window, from a few hours to a couple of days, kratom urine testing has become more widespread.

How Long Can Mitragyna Speciosa Be Detected In Saliva?

There is a possibility to detect its metabolites in the patient’s saliva, but there is no existing information about lab-tested kratom via the saliva drug test.

How Long Can Mitragyna Speciosa Be Detected In Hair?

As with many other pharmaceuticals, hair follicles can be used to determine if a person has recently taken a substance. Hair screening is also uncommon; however, hair follicles analyses have a longer detection window (for up to 90 days). Presently, there is no evidence about using hair for a kratom drug test, as well as whether the chemicals presented in Mitragyna speciosa are detectable in hair.

Does Kratom Show Up On A 10- Or 12-panel Drug Test?

Mitragyna speciosa does not show on 10- and 12-panel drug tests, because the chemicals presented inside of it are not the same as in illegal narcotics for which these screenings were created. So, the result will be negative. Sometimes 10-panel drug test can show a false-positive result for methadone.

Does Kratom Show Up On Probation Drug Test?

Typically, probation officers can request to check kratom on drug tests if this supplement is forbidden or not legal in certain areas. Also, using it or any other psychoactive substances could be restricted as the court’s condition of probation. Taking this herbal supplement is a risky thing, as some probation officers can ask for a special kratom drug testing or find it during a random home inspection that leads to imprisonment.

Does Kratom Show On A Military Drug Test?

Mitragyna speciosa use as a dietary supplement is prohibited by the Department of Defense (DoD). Military drug screening is usually taken for the most common drugs, which do not include specific kratom test. The substance will not show a positive result on the standard DoD test, regardless of Military Service Members are recommended not to use any products containing this substance. For the US AirForce and Navy, it is forbidden.

Can Kratom Show False Positive?

The results of lab-tested kratom received from the standard tests may not show mitragynine or the other alkaloids presented in the substance, as they are not suitable for detecting this kind of substance. However, the kratom false-positive result is possible if the drug is taken along with other supplements or medications. That is why tests are very sensitive, and it is better to conduct screening via the Gas Chromatography/Mass Spectrometry (GC/MS) method, which gives more accurate results.

How To Stay Away From Drug Misuse

In general, it is a herbal supplement that does not show on standard drug screening. However, there are specific methods that can examine kratom on drug testing. The most common is the kratom urine test that can show a positive result even on the fifth day after administration. The level of alkaloids and the strength depends mostly on the difference between kratom strains and dosage. However, the pharmacology of this herbal supplement still needs more research.

In specific cases like heavy side effects, it is recommended to address the symptoms to the doctor or professional addiction centers. Such rehabs provide necessary help and treatment for patients with substance use disorder.

    I have had pretty bad withdrawals lasting two weeks,stay away from this stuff
    • Jackson
      You must’ve been really overdoing it if you experienced withdrawals lasting that long. Keep everything in moderation and do your homework before using and you will be fine. If you only use it twice a week, you can be assured you won’t experience the withdrawal symptoms when discontinuing usage. If you use it regularly every day at moderate doses than you can expect the withdrawal symptoms, which are quite mild especially compared to actual opiates, to last about a week or less.

      If you have an addictive, compulsive, obsessive personality and have self admitted, at one time or another, as an Alcoholic/Drug addict I PROMISE you…the withdrawals are brutal and are JUST like withdrawing from Opiodes! I was ingesting over 30grams + orally by the end…it didn’t start out that way. It NEVER does. It’s subtle, it’s Progressive just like ANY mind altering drug. It starts off pleasant where 1/2 tsp does you well for 4-6 hours and them by the end, 15 months, I was taking 1/2 tsp. like EVERY HOUR! Today is Day 4 and the RSL is BRUTAL. Lack of sleep, chills, sneezing, body aches, lethargy are ALL there! I hope they ban this DRUG. It nearly cost me my life! I’m back in AA and I just want to be FREE and experience that natural high I got from helping others and having a connection with God!
      • Andy
        I hope you made it! I’m on day 11 and still kicking at night. It has been as difficult stopping this as it was stopping Suboxone. I’m hoping the RSL stops soon. Not sure how long I can deal with it!
        • Joe
          Don’t give up.. If not u will start all over again.. 11 days is miracle.. It is tough but u have made it.. Leave this stuff get clean and start your new life like other
        • Joe Beauchamp
          They sell restless leg and cramp pills at most pharmacies and they work for my wife. And yep , I am trying to get off opiates and now this crap has got me. Going to have to detox and am not looking forward to it. It will get you. Stay away.
  • Alice
    There is no way to “Keep everything in moderation and do your homework before using and you will be fine.” when using a mood altering substance like kratom especially one that chemically mimics opiates. I became fatigued and constipated; had altered liver function and tremors. I used kratom for five years and at the end when deciding enough was enough and it was time to stop, withdrawal was hard and took several weeks. I felt like I had the flu, body aches, fever, runny nose, headache, tremors, hallucinations, etc. Sound familiar? I wasn’t using a huge amount per day either. Jay’s comment about staying away is a good one. There is no substitute for staying clean.
    • jerry oneill
      I’m just wondering what did you do to get off kratom addiction. I’m committed to stopping but am trying to design a plan on my own .. HELP please
      • Joe
        I took tramadols 100mg and gabapentin 500mg for 7 to 10 days.. Consult your doc. The peak has eliminatedafter 7 days but then you must be mentally ready to combat fatigue and feel empty in your mind during post withdrawal.. It can last for up to 3 months before you will be back to 100 percent normal.. Keep busy during period.. And do sports it helps a lot
    • Temperamental
      Alice, Did you quit cold turkey or taper? Did you go through withdrawls on your own or did you have to get treatment?
  • Gary Pinchot
    Just wanted to give you a heads up that my pain management doc in Florida (whose ‘prescribing nurse’ is horrible) has claimed to have detected kratom in my urine over a month after I last took any. I literally called BS to the doc and I think he is just very anti-kratom and pro-suboxone(which is horrible for pain). So if you are being tested you may want to give yourself a little longer than 3 weeks if they send your test off to the lab.
    • John
      This is exactly right. Big Pharma doesn’t want Kratom on the shelf. Dips into profits
  • T
    Crazy crazy crazy, quit bad mouthing kratom. You are responsible for your actions. It’s a tool. Use it wisely not like a jay
  • Leo
    Oh my god, I had urin drug test done the other day and came up posetive for methadone, I DONT TAKE METHADONE, it was this stuff here KRATOM. I got into big trouble because of this. KRATOM INSIDE YOU WILL TEST POSETIVE FOR METHADONE
    • Amber
      Wrong Leo. You either did methadone or somehow it got into your kratom, which is highly unlikely. Both substances break down chemically in your body differently. It is IMPOSSIBLE.
  • Jaye
    Kratom will not make you test positive for methadone unless somehow methadone got mixed into your kratom. That’s just ridiculous. They dont even metabolize into the same things in the body which is why you have to be specifically tested for each substance (as opposed to a substance group like with some other substances).
    • K
      It also showed up as methadone in my ua. I.assure you I have never and do not take methadone.
  • John
    Does anyone have experience with kratom drug test and know for sure how long it actually stays in your system? I’ve passed after 4 days of not using but I was drinking a LOT of water/coffee those days and drank 2 qcarbo 16s (detox drinks) the day of the test. Anyone?
  • Beth
    Kratom will show in specialized drug tests that pain clinics use up to a month.. I have tested positive for it, I wanted to get the f**k off of opiates.. I have chronic pain it will never go away. When I have moderate pain it worked.. but for those bad days nothing helps.. I went as far as having a spinal cord stimulator put it only to have to have it removed because some of the metals gave me a bad reaction.. and I got a huge infection.. I wanted a holistic solution for the problem but all the doctors are pushing opioids or there counterparts.. it’s very frustrating.. it’s been said only use in moderation if you have problems with addiction stay away from it.. it is a tool in the holistic community.. not in the medical.. be safe and do your homework.
  • Kristin
    If I drink a lot of water and flush my self out how long do you think it will stay in my system
  • Ann
    Well I think it takes up to nine days to get out of your system. I haven’t taken any since Sunday and it’s Wednesday and I’m still not feeling my pain medication because it blocks it. Makes me so mad . I probably won’t feel it till Tuesday. I have tried to look up about Kratom blocking opiates all over the internet but there’s nothing about it on there. Has this ever happened to you?
  • Wy
    Make sure u have a reliable source for Kratom. I ordered some online and tested positive for Norbupenephrine, a metabolite of Suboxen. I got in big trouble. It never happened with store bought products but often stuff u buy online “May” be cut to make it seem stronger. I detoxed over 7 days, phenibut/Gaba helped. Kratom needs to stay legal, it is a tool that many opioid addicts need. [email protected]$& Suboxen
  • Kelly
    My urine test came back positive for methadone. I have never taken methadone, ever. It is the kratom. There is some incorrect info being given.
  • Jocelyn
    I was still testing positive for kratom at treatment after 25 days. And withdrawal was awful. I used occasionally and then a few times a week for a month or so and then daily for a couple weeks before treatment
  • Dawn
    I have been using kratom for 1year for severe pain I had a random drug test at work are policy is your job is safe if you let them know before the test is done if taken anything prescription needed well I did take a ferocet a couple days before I do not have a prescription for ferocet I let them know it would show up how ever I didn’t say anything about kratom because it is legal well now I’m trying to save my job any advice
  • Daniel
