How Long Does Kratom Stay in Your System
Before exploring how long kratom stays in the system of a user, it’s valuable to understand exactly how kratom works. Since it is such a new introduction in the U.S. market, a lot of people have misconceptions about kratom, or simply don’t know much about it.
This herbal drug is often promoted in the U.S. as a psychoactive substance that’s legal, and mitragynine is the main active alkaloid in the plan responsible for its effects. Mitragynine stimulates opioid-like activity in the brain, and it reduces pain response. When the active components of kratom reach the brain of the user, they influence mood and anxiety, and they have been shown to create a euphoric effect similar to what happens with opium or heroin.
There is some evidence indicating that for a long-term abuser of kratom, the substance could take around 5 ½ days to completely clear from their system.
- Age: Older people tend to have a longer elimination half-life than younger kratom users. This is the case with kratom as well as with most substances. In elderly people, most substances that are ingested orally will have a longer elimination half-life than in younger adults. This is usually due to factors such as renal function, age-related physical changes, and the use of other medications. It’s safe to assume that if you’re older, and particularly over the age of 65, kratom will stay in your system longer than it would in a younger person.
- Body Fat: Another personal characteristic that can play a role in how long it takes kratom alkaloids to be eliminated is the person’s percentage of body fat. The mitagynine in kratom is very fat soluble, which means that if you have a high percentage of body fat, you will likely retain the kratom metabolites longer than someone with a lower body fat percentage. If you have less body fat, you may be able to excrete kratom more quickly on the other hand, since it wouldn’t be stored in fat.
- Genetics: There are certain genetic markers and enzymes that may play a role in the speed at which kratom is eliminated from the user’s body.
- Food and Water Intake: If you were to take kratom with a meal that was high in fat, it could lead to faster absorption, which could also speed up how long it would take the substance to reach its peak concentration levels. If you’re well hydrated, it can also play a role in how long it takes for kratom to be excreted via urine.
Kratom Urine TestsSome kratom alkaloids may show up on certain urine tests. While research that indicates how long kratom would be detectable in a user’s urine is limited, there could be trace amounts detected in a urine test for over a week. For someone who doesn’t use kratom often or uses low doses, it probably would be detectable in their urine after a week. If kratom were to become illegal in the U.S., there would likely be more focus on urine testing as the preferred method to determine if someone was using it.
Kratom Blood TestsA blood test could be conducted to determine if someone took kratom, and how much they theoretically took. Blood tests can show concentration levels of kratom, and it is a substance that’s easily detectible in blood. If someone is a heavy or long-term user of kratom, there would likely be metabolites that could show up in blood tests for several days following ingestion, but because blood tests provide a shorter window for substances to be detected, and they’re more invasive, it’s more likely that a urine test would be conducted.
Kratom Hair TestsWith many drugs, testing of hair follicles is seen as a reliable way to test for substance use. It can also be done for a longer period of time. With kratom, however, there isn’t currently any evidence of hair tests being used. It wouldn’t be likely that kratom metabolites would appear in hair follicles, although as more research is done on this herbal substance, more work could be done on accurate testing which could include hair follicle tests.
Kratom Saliva TestsIt is possible that a saliva test could be used to identify kratom metabolites. Oral fluid testing is frequently used to test for a variety of types of drugs, but since this is most often done for legal drug tests, and kratom isn’t currently illegal in the U.S., this testing isn’t commonly performed for this herb.
