How long does kratom stay in your system? There’s no definitive way to determine how long the effects of kratom last, or how long kratom can be detected in your body. The duration can vary dramatically, depending on how much you take, and a variety of other factors.
However, understanding how kratom’s half-life works can give you a general idea of how long it stays in your system.
Half-life of Kratom
“Half-life” is a term used to describe how long it takes a drug’s concentration to be reduced by half. For each additional half-life, the drug is increasingly eliminated from your body. For example, if you take 100 mg of a drug with a 20-minute half-life, after 20 minutes, 50 mg of the drug would be left in your body. After 40 minutes, 25 mg of the drug would be left in your body, and so on until there is none left.
For kratom, half-life estimates range between around four hours and up to 24 hours. This means that only half of the amount will remain in your system as soon as four hours after you take kratom.
It is important to note that the half-life of kratom has not been extensively studied, and these are just general estimates.
How Long Can You Feel Kratom’s Effects?
You can usually start feeling effects within 30 minutes to an hour of taking kratom, but some people may feel effects in as little as 15 minutes. The effects can be felt for five to seven hours. However, most people find that the most potent effects are between two and four hours after taking it.
It is important to note that kratom affects everyone differently, and these timeframes are simply a guideline. The overall duration of effects will depend on a variety of factors, including the amount you take.
How Does Kratom Affect the Brain?
The two main compounds found in kratom are mitragynine and 7-hydroxy mitragynine, which interact with and stimulate receptors in the brain to improve cognitive function. In low doses, it can act as a stimulant, similar to caffeine, but without the jitters. Kratom’s interaction with brain receptors may support:
- Reduced anxiety
- Lowered pain sensations
- Improved focus
Does Kratom Show Up on a Drug Test?
Kratom is not considered a controlled substance, and standard drug tests, including blood tests and urine tests, will not detect kratom. A drug screen looks for specific substances or its metabolites per federal workplace drug testing guidelines, and these screens do not look for the alkaloids in kratom.
However, some screens that are designed to test for kratom specifically. For these tests, kratom can show up as long as seven days after taking it. However, many factors affect how long the drug will stay in your system, including how much you take.
The effects of kratom can be felt between five to seven hours after taking it. However, it can stay in your system for much longer. Most drug screens do not test for kratom, and it is not considered a controlled substance under federal guidelines.
