Kratom misuse requires a comprehensive psychiatric and physical evaluation by a qualified clinician. So, always refer to a board-certified physician or mental health specialist for a specific diagnosis and treatment.
Kratom is an evergreen tree native to Southeast Asia. It is also known as biak, kakaum, ketum, thang, and thom. Kratom contains two main psychoactive ingredients - mitragynine and 7-hydroxymitragynine - which give rise to a high, which is why kratom comes with a risk of misuse and dependence. While kratom is not a controlled substance in the U.S., some states can impose regulations and prohibitions on kratom use - which is why knowing how long kratom lasts in your system enables you to make informed decisions with regard to your safety and well-being.
Typically, kratom stays in your body anywhere between 2 and 9 days after the last dose; however, depending on the drug testing methods used, it can be detected for even longer.
What Is Kratom Half-Life?
Kratom's half-life is around 3 hours. This refers to the time taken for kratom in your body to be reduced by half, then another half of the remaining half, and so on. It takes several half-life cycles before kratom is entirely cleared from your system.

What Factors Impact How Long Kratom Stays In Your System?
Kratom stays in your system anywhere between 2 and 9 days after the last dose. However, some factors can further impact this time:
- Dosage and Frequency: Higher the dosage and more frequent the use, kratom remains in your system for a longer period of time.
- Metabolism: Metabolism is responsible for breaking down kratom, so faster metabolism rates lead to quicker elimination.
- Age: As aging slows down metabolism, it can take longer for kratom to be cleared from the body as one ages.
- Liver and Kidney Functioning: The liver and kidneys are respectively responsible for metabolism and excretion. So, pre-existing liver or kidney conditions can slow down the elimination time.
- Body Mass: Greater body mass can lead to longer retention time.
Does Kratom Show Up On a Drug Test?
Kratom does not show up on the general 5-panel or 7-panel drug tests, as they commonly test for amphetamines, barbiturates, benzodiazepines, cannabis, cocaine, and other drugs like PCP and ecstasy.
However, kratom can be detected with specialized, lab-based tests that specifically look for mitragynine and 7-hydroxy mitragynine.

Can Kratom Misuse Be Treated?
The National Institute on Drug Abuse (NIDA) says that there are presently no U.S. Food and Drug Administration (FDA)-approved medications to treat kratom misuse or dependence, so it is primarily treated with behavioral therapies.
Some of the widely-used therapeutic modalities are motivational interviewing, cognitive behavioral therapy, contingency management, and 12-step facilitation therapies. Group therapy, family therapy, and healthy living practices like meditation, mindfulness, and peer support can also be effective when combined with traditional therapy.
