Kratom is an evergreen tree found in the southeastern countries of Malaysia, Thailand, Indonesia, and Myanmar. If you haven’t heard about it, you probably would be alone considering its leaves have been used as a medicinal herb since the nineteenth century.

Nowadays, its usage has also spread to being more of a recreational drug, though it is still used to this day as a form of medicine.

Since it’s a fairly new addition to the U.S. market, you probably don’t know much about it. If you’re like the few people who do know about it, you’ll probably have a few misconceptions about kratom, too, which you might’ve read online. However, all those misconceptions about How long does kratom last? will be cleared in due time as they’ll be discussed later on in this article.


What is Kratom?

As previously mentioned, it is the name of a tree found in Southeast Asia. Kratom functions similarly to opioid drugs. The two main constituents found in the leaves of kratom, mitragynine, and 7-ho-mg, bind with opioid receptors in the brain to activate the release of dopamine and serotonin. This leads to euphoric effects, sedation, and even causes pain relief.

Since it acts much in the same way as opioids, it can be thought of as a cheaper alternative to it. Due to its behavior as an opioid, it would most likely come with opioid withdrawal effects.

Like most drugs did in the past, including cannabis, kratom too comes with its myths and misconceptions. Over the past few years, as it transitioned from Southeastern Asia to the U.S. market, the internet has flooded with various kinds of information regarding the tree and its leaves. How reliable is that information?

Myths and Misconceptions Regarding Kratom

With its growing popularity, kratom has essentially become a target for misinformation. The Internet is overwhelming with facts and figures and gullible Internet users not knowing better than to trust a random website, it’s easy to be caught in the slightly bad reputation that kratom use has garnered.

Remember, when searching up information on the web regarding kratom, or anything really, it is important to make sure you’re reading science-backed articles or scientific journals. The use of kratom has been long backed by scientists and other licensed medical professionals. They have been advocating for its continued legality and dispute those creating rumors against its use.

Basically, we can name myths as

  • Myth #1: It’s a Synthetic Drug
  • Myth #2: Kratom is Bad for Your Health
  • Myth #3: Kratom has not Been Studied or Researched

Myth #1: It’s a Synthetic Drug

A major myth surrounding kratom is that it’s actually a designer drug. This myth comes around due to the fact that kratom’s growth in popularity came around the same time as the ‘bath salts’ and ‘incense’ craze.

Due to kratom being on shelves while other analog substances were flooding the market, its reputation was hit badly. These analog substances were propping up in the news as a legal means of getting high since they were available at every convenience store. As a result, state legislatures sprung into action by barring selling and possessing the substances sold at these stores. They passed ‘blanket bans’ for synthetic drugs, whilst naming the compounds found in kratom.

However, despite all this misinformation, it should be known that kratom is a completely organic, herbal drug. Luckily for kratom, most states realized their mistake of referencing kratom as a synthetic substance and reversed the ban.


Myth #2: Kratom is Bad for Your Health

Another piece of misinformation that spread like wildfire regarding kratom was that it was hazardous to one’s health. 

The Drug Enforcement Administration (DEA) and the Food and Drug Administration (FDA) have both chosen to trust the words of the famous John Hopkins University professor and former head of the NIDA, Dr. Jack Henningfield, who is reported to have called all the claims regarding kratom being injurious to health as “Junk Science” and made mention that the claims were only put out to hurt the tree’s reputation.

However, before trusting the word of Dr. Jack Henningfield, the FDA made claims that the drug was responsible for several deaths. However, this was quickly disproven by molecular biologist Dr. Jane Babin and forensic toxicology consultant Dr. Karl Ebner.

The two doctors had pointed out to the FDA that there were other factors that coroners had attributed to kratom which were known to cause death. In most circumstances, it was an assortment of pharmaceuticals that were known to be dangerous.

Scientists have even tried to induce death in lab rodents by way of injecting them with common compounds found in kratom, namely mitragynine and 7-ho-mg. However, it was all to no avail.

The reported conclusion; there have been no deaths, of humans or lab animals, that can be linked to kratom usage.


Myth #3: Kratom has not Been Studied or Researched

This final myth on How long does kratom last? is probably the most common misconception you can find on the internet regarding kratom, but it is completely false.

It has been part of the annals of studies and medicine, including studies done in the west, for several centuries now. 

By the early twentieth century, scientists were already well underway in their works of isolating and synthesizing its main compounds.

Since then, pharmaceutical companies all over the world, including the ones in the U.S. and Europe, have conducted vast amounts of research on the tree. A famous example is the one of Dr. E.J. Shell and who had carried out a great deal of analysis on the mitragyna speciosa, during the 1970s. 

The past few years have seen an exponential rise in the interest of studying kratom, with hundreds of studies being published and flooding the Internet in the last couple of years alone.


How Long Does it Take for Kratom to Take Effect?

When a person intakes kratom, its effects usually begin to kick in within 10 to 15 minutes. Confirmed by anecdotal evidence, a small dose of the plant can last for around two hours, whereas higher doses can last you up to eight hours.

A low dose of kratom could be considered to be around four to five grams, while higher doses could be found in the range of seven to eight grams. The peak effects of kratom are confirmed by anecdotal reports to kick in between 1.5 to 2.5 hours after ingestion.

Kratom effects can be heightened by taking kratom on an empty stomach. If one eats before taking in the plant, kratom’s effects could take longer to kick in.

It should also be noted that the time it takes for kratom to take effect depends on the type of kratom use a person carries out. if kratom is consumed in its capsule form, kratom’s effects, once again, would take longer to occur. Though, this could potentially be mitigated if it’s taken in high doses. Alternatively, if one is smoking kratom, the effects would kick in a lot sooner but would fade away just a quick.


Half-life of Kratom

If you’re like most people, you’re probably wondering how long kratom stays in your system if you stop using it? A person who has kratom dependence, but wants to stop consuming it, would be worried about how long kratom withdrawal symptoms last, and more precisely, when the withdrawal symptoms begin?

Another concern one could have regarding its half-life would be how long kratom stays in your body if you were going to be drug tested? Though it should be noted that kratom doesn’t often show up in certain drug tests, unlike other drugs. 

Due to the amount of research conducted, there isn’t a substantial amount of information on the half-life of kratom. It has mainly been studied in-depth on animals. However, with the research conducted thus far, it’s believed that the main active alkaloid, mitragynine, has a half-life of around 23 hours and 20 minutes.

Based on the above-mentioned research, it would take just under a day to get rid of half the kratom in a person’s system. It would also take just over five days to completely get rid of the kratom from the person’s body.

Based on more modern research the half-life of kratom can be as little as two hours, and be completely out of your body within half a day. Though some studies are pointing to an upper limit for the lower end of the half-life spectrum, and claim that it could take as many as nine days to have your body fully cleared out of the kratom effect.

It should be noted that people who take kratom in low doses can eliminate it out of their system faster than kratom users with a kratom addiction. Thus, it can be said that kratom’s half-life is very much dose-dependent.


What Can Influence the Length of Time Kratom Stays in Your System?

There are a lot of factors and variables that can increase or decrease the length of time kratom stays in one’s body, and in turn, it can affect the duration of your kratom withdrawal. Some of those factors include the following:

  1. Age
  2. Body Fat
  3. Food and Water intake


In the case of orally ingested kratom, old people would take longer to eliminate the kratom from their bodies than younger people. This is often due to things such as renal function, and the use of other types of medication.

Body Fat

Another factor for the time it takes to eliminate kratom from the body is ‘body fat’. Since the main compound in kratom is fat-soluble, people with a high body fat percentage would often take longer to get kratom out of their systems. Weight loss would be a good idea to keep the kratom running out of your body after substance use.

Food And Water Intake

Your diet can also determine how long kratom lasts in your body. A high-fat meal could lead to quicker absorption, which in turn could help reach the peak concentration levels faster, after substance use.


Does Kratom Show Up in a Drug Test?

A major reason for kratom use over other opioids, aside from not having to deal with some of the usual toxic effects of opiate withdrawal symptoms, is the fact that they don’t show up on many of the standard drug tests.

However, it should be noted that kratom alkaloids can be found in other forms of a drug test, such as urine tests and blood tests. Due to blood tests being more intrusive with a smaller detection span, a special test for kratom called the ‘Kratom 12-panel test‘ is often used for finding traces of kratom use. This will surely give you sie of relief on How long does kratom last.
