Does kratom show up on a drug test?

Kratom is a new green remedy product on the shelves nowadays, and it is moving fast due to its popularity. It has gained much popularity due to its many therapeutic effects in pain relief, stress alleviation, battling against insomnia among many other benefits.

Despite these many positive effects, kratom comes with its chain of side effects that if not checked properly can be fatal. Due to the fatalities involved with its long-term consumption and overexposure, it has been banned in some states and countries prompting its test. The kratom test will be performed on a suspected user to ascertain whether he or she has been using kratom for a specified number of days.

The kratom test

As said earlier the kratom test will be conducted to ascertain whether someone has been consuming kratom for a specified period. So far no test has made a come through to prove the use of kratom. However, there are advanced tests that check on the alkaloids that are mostly present on kratom to give a correct conclusion. It mainly tries to detect for the alkaloid mitragynine which is in most cases abundant in kratom.

This alkaloid can be detected in urine, blood and sometimes sweat and it is all dependent on the dosage taken. The dosage will, in turn, have a direct effect on the half-life of this alkaloid and others. The detection will also vary with the mode being used.

The half-life of kratom and its metabolites

The half-life of a drug is the approximate number of hours that it takes to be completely diminished in the system by means of excretion. Kratom’s alkaloids roughly have a half-life ranging from 16 to 24 hours. This is dependent on a lot of factors though. So, for how long does kratom stay in your body? Let’s have a look at that.

How long does kratom stay in the body?

The main alkaloid in kratom is mitragynine which has a half-life of 16-24 hours (mentioned earlier). This means it will take a day for half of the kratom consumed to be rid off from the body mostly through excretion. However, it may take up to 5 to 6 days for the associated alkaloids to be excreted entirely as they will be converted to their respective metabolites which roam freely in the blood.

It has to be noted that the duration of kratom in your body is dependent on many factors that affect its half-life or metabolism. Among the factors are as follows:

Dosage consumed

The dosage consumed is a significant determinant on the duration that a drug will stay in your body. In large doses, it will take a very long time for the alkaloids to be wholly gotten rid off from the body. This is due to the high threshold of kratom that will be in the body in terms of the alkaloids.

Frequency of consumption

For frequent users, the alkaloids will take long to be completely flushed out of the system. This is because some of the associated metabolites of the alkaloids will be incorporated into the body tissues such as fatty tissues which become quite hard to be excreted.

Mode of ingestion

The mode of ingestion will also influence how long the alkaloids will be present in your body. Some modes such as direct ingestion and use as suppositories will pack a large dose of kratom, which will take longer to excrete. This is compared to modes such as smoking and topical application which will take a shorter time to eliminate.

The weight of the person

The weight of the user will also influence the rate at which these associated alkaloids are present in the body after its consumption. For people with large body fat composition, the alkaloids will take relatively longer to eliminate. This is because the alkaloids are fat soluble and will be stored in tissues with fat in their fat cells. This will make it harder to excrete and will take a long time for it to be eliminated from the body.

The activeness of the person

If a user is more active, he or she will have a higher metabolic rate which will fasten the rate at which their bodies eliminate metabolites. In persons with a higher body fat content, a regular body exercise regime will make them burn more body fat for the body’s energy needs. This will clear up a large amount of the fat-soluble metabolites in a very short time.


Age has an influence on the duration of metabolites in your system. Older people have aged out renal and hepatic systems which break down and eliminate waste from your body. This will mean that it will take a relatively long period to eliminate such waste in alkaloid metabolites from the body; hence they will last longer. These are among the many factors that will determine how long the kratom’s alkaloids will last in your body.

Modes of detection

Apart from blood and urine, it can also be detected in your saliva, hair, and sweat. These modes of detection have different duration spreads in which they can detect the presence of the alkaloids.

In saliva and sweat, it will only detect the presence of the mitragynine alkaloid for up to 6 hours while in urine it can be detected for up to 5 days or more depending on dose and frequency.

In blood due to the dissolving of the alkaloids metabolites in a fat cell, it will be detectable for up to weeks since their last consumption.

Hair will store information in the composition of the metabolites from the body. For this reason, it will have traces of mitragynine’s metabolites, which will show in a hair test. The hair test will produce such information for even three months after consumption. It may reflect for more extended periods in frequent users.


The kratom test is majorly prevalent in areas where the use of kratom has been banned. It can also be taken when somebody is hooked and addicted to kratom and want to check on a possible rehabilitation method.
