How long does Kratom stay in your System!!!!!
People sometimes wonder if they can pass a drug test when using kratom. Drug screenings are often done as part of the hiring process. There are also situations where random, unannounced, surprise drug tests are administered during a person’s employment at a company.
Even when such substances as cannabis and kratom are legal in an area, an employer may still be wary of anything that they think might impact a worker’s job performance. Often these concerns are justified, but sometimes it’s just lazy acceptance of lamestream media misinformation or old-fashioned prejudice against certain substances.
Notice that there don’t seem to be any alcoholism tests for employment, but alcohol abuse can definitely have an effect on a person’s job performance, attendance, and overall health and personality.
Kratom is not detectable on most standard drug tests, such as the common 5-panel drug test, but some kratom alkaloids can show up on certain drug tests that use samples of your urine or blood.
There is also a drug test that specifically tests for Kratom. It is known as a 10-panel drug test. When using a 10-panel drug test the substance can be detected for up to 7 days after use, but many variables can influence how long the drug can be detected in your system.
So, you’re wanting to apply for a job, but you know they do drug testing. You start to be concerned about a few things. Will this testing discover kratom in my body? Or is there some special test that has to be done to find kratom in a person? Will they ask me if I’m using any drugs not prescribed by a physician?
What if I stopped taking kratom a little while ago? Are kratom alkaloids still lingering within me? How long will detectable traces of kratom remain in my system?
Confirm Biosciences states the following…
QUOTE
While kratom contains alkaloids that bind to opioid receptors in the brain, they are not structurally related to opioid drugs and are therefore not detectable through opiate drug tests.
That is not to say that these kratom alkaloids are not detectable in body fluids, because they are – it’s just that they are not normally tested for because kratom is not illegal.
In the workplace, standard 5-panel drug tests only test for cannabinoids, cocaine, amphetamines, opiates, and PCP (SAMHSA 5).
If employers have reason to believe that an employee may be misusing kratom and that its side effects may be affecting that employee’s productivity and the overall safety in their workplace, notwithstanding kratom’s legal status, said employers would be within their rights as may be provided for in their drug-free workplace policy, to request for that employee to be tested.
This should work in much the same way as testing for prescription drugs which are also legal.
In drug screening, the cut-off level is the minimum amount of drug residue that must be found in the sample in order for the test to be positive. It is important to remember that a negative sample does not necessarily mean that it is drug-free, only that it contains a drug at a concentration that is below the established cut-off.
Urine drug test – The average (high-dose) user takes some 5.3 days to completely flush out kratom alkaloids from the system, so trace quantities of metabolites may be detectable in urine for over a week.
END QUOTE
Mitragynine is the main chemical (called an alkaloid) in kratom that produces effects. Mitragynine can be detected in typical drug test urine screens.
So, how long does kratom stay in your body after your last dose of it? It depends on many factors, but general statements can be made.
Half-life is the key term here.
The half-life of the drug is the amount of time that it takes a person’s metabolism, particularly the liver, to break down the drug, and reduce it by half (50%) its concentration in the person’s system.
A drug is proportionally eliminated from your system within the time span of each additional half-life.
Thus, if a 100 mg dose of an IV drug with a half-life of 15 minutes was given to a patient, it would take approximately 15 minutes for 50 mg of the drug to remain in the system; it would take 30 minutes for 25 mg to remain; 45 minutes for 12.5 mg to remain; 120 minutes for 0.39 mg to remain; and so on.
It is generally considered that in order to completely eliminate a drug from the body under most conditions, it takes about 5–6 half-lives; but this is a general figure. The actual elimination of any drug in a person is dependent on a variety of personal and strain-dependent factors.
Thus, based on this information, for most individuals, detectable amounts of kratom will be gone from your blood plasma in about 24 hours, but it would take about 5–6 days to totally eliminate the drug from your system.
To get even more technical, there is Terminal Half-life and Elimination Half-life.
Terminal half-life is the time it takes for the plasma concentration of a substance to be divided by 2 after reaching what is called pseudo-equilibrium. Terminal half-life isn’t an indicator of the rate of elimination, but rather how much kratom is absorbed and how quickly the absorption takes place.
So avoiding a positive test isn’t as simple as making a calculation based on the elimination half-life.
Here are some other factors that determine the alkaloid content of the kratom you use, and exactly how long kratom will persist in your system at drug test detectable levels:
The specific strain of kratom (Aceh, Bentuangie, Malaysian, Vietnamese, Indo, Sumatra, etc.)
Exactly how much kratom you took in your last dose, before you stopped taking kratom (to pass the drug test)…at least you don’t have to worry about your usage several days in the past!
Your body weight, fat percentage, and speed of metabolism (how fast your system processes substances) – heavier people retain kratom longer than skinny people.
Age of the kratom plant when it was harvested.
Your own age (older folks process substances slower than younger people).
How much activity you engaged in while taking your last dose of kratom (moving around, exercising, walking, etc. will move the kratom through your system faster).
How healthy and active your liver is.
Other drugs you are using (their combinations can have an impact on how you process them).
Growing environment (soil and surrounding plants, insect populations, etc.).
Climate conditions in which the plant grew.
Time of harvest.
Drying and fermentation processes.
Purity of your kratom (ALWAYS insist on fresh, 3rd party lab-tested products, and know that disreputable vendors may add phenibut, opioids, niacin, or other contaminating substances in an attempt to boost its effects).
Please remember, even if a substance like kratom or cannabis or magic mushrooms is legal where you live, that doesn’t mean an employer is going to be okay with their workers using them.
Hopefully, as more research is conducted, we will learn more about our beloved kratom and its wonderful properties. And employers will stop being so clueless about something that brings so many benefits to those who take it!

Very helpful post. I’m a wee bit late finding it because I’m on a medically necessary kratom break right now and am curious how long it lasts in my system. Tho they are not testing for kratom but I’m having to rule out kratom as participating in issues I’m having.
I sure have been wondering about the half-life as well as how to really understand half-life because I suck at math.
I think a lot of people will benefit from this information! Thanks for posting it here!
Have a wee bit better day!
@laurie awesome that you found use in it the content. Much appreciate the reply. I hope you can take a break from the break from Kratom, lol, in the foreseeable future. Good luck and hope that this isn't a medically advised necessary time-out from the leaf. If so I wish you quick healing and recuperation from whatever ails you.

What a sweet reply @leafoflife! I’m hoping it’s a short term kratom break also because I’m injured and could really use some pain management! The timing sucks, but my experience will be helpful to others who may feel they “can’t” take a break. I was one of those! No offense, I have ongoing conditions and honestly thought I CANNOT take a break. I was using stem n vein and finally I have some crushed leaf for tea that I’m hoping I can use very soon.
My family and friends thought I would never actually stop, even for a day! But I’ve learned that it CAN be done if you care enough about your self care management. I’m definitely not comfortable at the moment, but life just isn’t comfortable all the time!
Sleeping with a serious injury has been difficult, but my doctor also won’t take me seriously until I get blood and urine done without kratom. Which the lab was CLOSED “for technical reasons” when I pulled up at 8AM. LOL
Heading back down there, but I’m staying off the kratom for a good while to see what’s going on with my health and I’m so glad to have my kratom use removed as a potential cause (I get so tarred of people saying kratom causes this and that, it’s my kratom USE that needed to be changed! Not the substance causing me issues, lol).
Thanks again for all of your participation here and in other areas for our community! @somethingsacred Brandon loves your kratom and I’m pretty sure he was willing to spare a tiny bit of it and left it in a sample bag for me recently. I look forward to trying it again, but that kid is tight with your leaf! I’m pulling his chain! He’s very sweet to share and I love swapping with him!
Have a wee bit better day!

https://www.kratomplants.com/how-long-does-kratom-last-kratom-half-life-duration/
Half the effects at 4 hours, one fourth the effects at 8 hours, one eighth the effects at 12 hours, one sixteenth at 16 hours, one thirty-second 20 hours, one sixty-fourth at 24 hours. Think of it as a loaf of bread in your hands that gets cut in half every four hours. If using 5 hours for the half life, then it could go something like this. Take Kratom at 7 AM, it's at full effect soon after. Call that 7:30 AM for the alkaloids to have been absorbed, and working. So at 12:30 PM the alkaloids present are just 50% as effective as before. 5:30 PM they're at 25%. 10:30 PM - 12.5%. 3:30 AM - 6.25%. And after just over a day, at 8:30 AM, they are only 3.125% as effective.
7-hydroxymitragynine, unsurprisingly, breaks down faster, so figure something like, if it was absorbed at 7:30 AM, 10;30 AM - 50%. 1:30 PM - 25%. 4:30 PM - 12.5%. 7:30 PM - 6.25%. 10:30 PM - 3.125%. 1:30 AM - 1.5625%. 4:30 AM - 0.78125%. 7:30 AM (a full day later) - 0.390625%.
Some tests can be wickedly accurate, and so what seems like a trifling amount to us can be more than enough to meet a detection threshold. But hyper-accuracy usually costs, so we have a situation where the public has some idea of how long they need to allow for a drug to clear their system.
Off topic, but that kind of progression reminds me of the tale of the person who was asked by a wealthy and powerful King how much he'd want to be paid to supervise the building of a pleasure palace for the ruler. The person said, "Pay me but a penny a day for the honor, but double that every day." They may or not may not later have had their head cut off after the King's treasurer did the math on how much salary that meant, before too long. lol 🙂
Kratom Half Life
The term “half life” refers to the length of time that the effects of any given substance diminish by half. Generally speaking, that is when the user can feel the effects of a substance at its “peak”, or strongest point.
Kratom half life can be determined by the half life of each of its alkaloids. Due to the fact that each strain of kratom contains a different number of alkaloids and in different concentration levels, it’s nearly impossible to say exactly what the half life of kratom is. Kratom’s half life varies, depending on the strain and vein color you’re taking.
Considering that fact, it has been determined that the half life of kratom is 3.85 +/- 1 hour.
I know what you’re thinking… what on earth does that equation mean?!
Well, 3.85 +/- 1 hour signifies that it will take approx. 4-5 hours for the effects of the alkaloid mitragynine to wear off by half. Additionally, 7-hydroxymitragynine (kratom’s other prominant alkaloid) has a half life of 2.5 +/- 0.7 hours, as in about 2.5-3 hours to reach its halfway point. So, on average kratom takes 3.5-4 hours to reach its half life. This is an average number, not an exact answer – it varies as we mentioned above.

awesome info ! Thank you so much for posting this 🙏🍂
I actually haven’t tried Leaf Of Life products yet .... but have tried Your leaf Your life .... very similar name .
Def leaf of life is on my list to try .... especially after having some good dialogue from Martin .
Really appreciate these informative threads 👍👊🍂🙏
Life is better with Kratom

@somethingsacred Yes, your leaf yur life is actually "Philly Kratom", which we are good friends with. I would be honored if you give us a try, please use our first-time client code 'First15" for 15% off at https://leafoflifekratom.com Thanks, and super appreciated. Of course, as most of us, we are also dealing with the T1 payments dilemma which you may have heard of that affects 3/4 of the industry. We do have alternative processing in place though. 😉
@somethingsacred if you are part of the ILK team, i will gladly send you some samples of course

@somethingsacred Brandon IS the primary online moderator now and I just pop in now and then. He is “in the trenches” more, but both of us are multi-platform visitors. He consults with me when necessary, but he brings the good energy and kindness this forum is known for. I can’t believe how lucky we are to have found him! And he ALSO lives about 2 miles away! He’s been a wonderful moderator, with a kind and helpful demeanor. We only found out we live near one another after about his first year here! LOL
@somethingsacred Brandon and @leafoflife THANK YOU for clarifying that sample(s) as being Philly Kratom.
I’m stuck abstaining from any kratom use right now or I would ask for some samples (at a reasonable fee, of course).
@somethingsacred Brandon also does awesome reviews on various platforms, so I recommend you hook him up.
ALSO, thanks @leafoflife for posting the discount code so he and I can direct members to this post/code.
@Babel-17, THANK YOU for always having more to ponder. I continue to learn a lot from your research and perspective!
Have a wee bit better day!

Its such a disappointing situation with T1 dropping so many vendors. It’s just ridiculous all the BS kratom companies have to navigate to make the wheel keep turning and to continue providing this special herb is consumers that benefit tremendously from it .
Sean , aka Philly kratom is a wonderful human . Ive been chatting with him over email and text . Had a nice chat on the phone as well. Really respect that guy and love his products . One of my preferred vendors .
Im on the ILK crew , Laurie my dear friend and mentor adopted me into the mod team. She’s always addressing the sight issues and communicating the needs of the forum . She’s a gem ! By all means , she’s the fire behind the scenes ,,.. getting $hit done 🙂
I keep an eye on things , serving the best I can for members and vendors . My way of contributing to the community.
Im always happy and interested in trying new vendors / products . I’d be stoked to try some product samples. I can PM you and we can chat if that sounds good to you ?
I absolutely love this community, means the world to me . Krstom is a driving force in my life , as is doing whatever I can to keep kratom legal. Iwas a major ganja head for most of my life ( rarely now lol) I was into activism where I live . I’ve been much more of a activist with kratom however . Both are very important herbs , but kratom is the one that’s given more than I could ever have hoped for. Keeping our “rights” our rights .....I’ll be damned if I roll over and let big pharma/effed d a and big brother tell me what herbs I can or cannot take into my body . Free country? Lol, we are only free if we exercise our rights and make respectful noise when injustice is being handed out .
sorry for the rant , it’s on my mind all the time 😎🍂

@somethingsacred Yes of course I would love to send you guys some samples and see what you think. Just shoot me your address/s to our company email contact@leafoflifebotanics.com and we'll make this happen.
Yes ganja, lol. Been a proponent for most of my life and it has given me the thought process and creativity needed which are both important in my business endeavors. For the last 22 as a tattoo artist and shop owner as well the last 6 years as a Kratom vendor. I do have to say that I never thought about the hurdles that are faced in this industry. If I would have known I might've never started, but it was a matter of necessity that began this whole journey.
Prior to the 2016 shake-up and the horrors that were in grasping distance of the possible scheduling drove me to buy a bunch in bulk to stack up in case of unavailability. Thankfully this never happened in thanks to 140000 of us who said "NO" we won't let them dictate what we can or cannot use to treat our ailments with natural substances instead of synthetics which oftentimes make things worse just for the sake to dump more into billion $$ multinational corporations that won't stop of nothing to illegalize plants, roots, herbs and so forth as they cannot be patented.
A funny anecdote is a fact that the pharma boys patented the main alkaloids of Kratom before 2016 and hoped for scheduling to present it in a synthetic lab-derived version, which they now claim it has no beneficial value, lol.
It's so easy to see through their dirty tactics, but it is a David vs. goliath scenario to go up against those who try to smear and discredit, as well as seize and illegalize these products. As we have seen as of late with the raids and confiscations that took place.
Thankfully we are better organized nowadays but to cannot be complacent in the "wrongful" assumption that we are getting left alone to do what we do. Anyway, we keep on keeping on, and hopefully one day this will come to an end as it has for the MJ plant. Even though this is still a long road to be traveled.

Right on Martin,
And a resounding yes to all you just wrote .
It’s beyond ridiculous all the antics the FDA has pulled and continues to pull. It’s an abuse of power ....they have no merit in being this way !!
Thank you for offering some samples for me to try . I’d like to throw down some $ as well. I love free samples but I also love supporting vendors . I’ll email you 👍
Plant medicines are where it’s at . We are wired to utilize these herbs... and as adults , should we not decide what plants we choose to help our lives ?? It’s our constitutional right !!!
Life is better with Kratom
😎🍃kratom saves lives 🍃😎

Great thread! @leafoflife, you are so right about the challenges before 2016 and since. A lot HAS NOT CHANGED. The large confiscations still occur without warning or merit. The challenges in keeping the leaf legal by implementing the GMP Compliance process…wow, that’s been a huge investment into an undetermined future. I definitely wonder if the new vendors entering the market now have looked at recent history before jumping in. Just for the sake of not being hit by a stone wall of complications and EXPENSES to merely help others get quality kratom at reasonable prices!
Great discussions and positivity as the “war” lingers on..!
Have a wee bit better day!

Oh and I love you, too, @somethingsacred Brandon! I am still grateful for the day you showed up on the forum. And every day since! Thank you for the contributions and support for our entire community!
Have a wee bit better day!
