Kratom, a botanical derived from the leaves of Mitragyna speciosa, has gained popularity for its potential to promote energy, enhance mood, and provide natural relief. As its use becomes more widespread, a common question arises—how long does kratom stay in your system? Whether you’re a new user curious about how your body processes it or someone preparing for a drug screening, understanding kratom’s half-life and detection window is essential.
The primary active compounds in kratom are mitragynine and 7-hydroxymitragynine (7-OH), which interact with opioid receptors in the brain but are structurally different from traditional opioids. These alkaloids are metabolized primarily in the liver and excreted through urine.
The length of time kratom stays in your system depends on several factors, including dosage, frequency of use, body composition, and metabolism. Here’s a general breakdown:
|
Method of Detection |
Detection Window |
|---|---|
|
Urine |
1–9 days |
|
Blood |
Up to 24 hours |
|
Saliva |
Uncommon / Unknown |
|
Hair |
Up to 90 days (theoretical, rarely tested) |
• Urine Tests: Most common and effective. Occasional users may only show kratom for 1–3 days, while regular or heavy users may test positive for up to 9 days.
• Blood Tests: Detectable for less than a day. Useful in clinical settings but uncommon for standard drug screens.
• Hair & Saliva: Kratom is rarely included in panels testing these samples.
1. Dosage & Frequency: Higher and more frequent use leads to longer detection windows.
2. Body Fat: Mitragynine is fat-soluble, so individuals with higher body fat may retain traces longer.
3. Metabolism: Faster metabolic rates may reduce how long kratom stays in the system.
4. Hydration & Diet: Water intake, food consumption, and liver health can influence the body’s elimination speed.
5. Age & Genetics: Natural variances in liver enzymes can impact how quickly kratom is metabolized.
“Understanding how kratom moves through your body isn’t just about timing—it’s about using nature’s tools with intention and responsibility.”
Scientific studies suggest that the half-life of mitragynine is roughly 24 hours, meaning it takes a full day for your body to eliminate half of the active compound. It typically takes around 5–6 half-lives for a substance to be cleared from the body, which equates to 5–6 days for occasional users.
As kratom enters mainstream conversations, particularly in wellness and recovery communities, education is key. Understanding how your body processes kratom is crucial for safe and responsible use.
If you’re using kratom regularly or in high doses, it may linger in your system longer than you expect. Transparency with healthcare providers and awareness of how kratom could interact with medications or testing protocols is part of being a responsible user.
Kratom can offer a wide range of benefits, but it’s essential to stay informed—especially when it comes to how long it stays in your system. While kratom isn’t commonly included in routine drug testing, it can still be detected under certain circumstances. Your unique physiology, habits, and lifestyle all play a role in how your body processes this natural botanical.

Not on standard drug tests. However, specialized tests can detect mitragynine, especially in legal, clinical, or forensic settings.
Kratom Detection by Drug Test Type
Urine Tests
Kratom will not show up on a 5-panel urine test since it doesn't screen for kratom’s specific alkaloids. However, kratom can show up on a 10-panel urine test.
Blood Tests
Blood tests for kratom are typically only used in medical settings because of their invasive nature. Due to their short detection window, they are mainly useful for detecting intoxication. Although kratom exits the bloodstream fairly quickly, positive results may appear for 1-3 days after the last dose.
Saliva Tests
The alkaloids in kratom are not typically included in standard saliva drug testing panels. This type of test is unlikely to detect kratom.
Hair Test
Hair tests are rarely used to screen for kratom, but they can detect illicit drugs in your system for up to 90 days.
Typically 1–3 days for occasional users and up to 7–9 days for frequent or high-dose users. Kratom will not show up on a 5-panel urine test since it doesn't screen for kratom’s specific alkaloids. However, kratom can show up on a 10-panel urine test.
In theory, yes—for up to 90 days. But kratom is rarely screened in hair tests unless specifically requested.
There are numerous factors that determine how long kratom stays in your system. Dosage, frequency of use, body fat, metabolism, age, hydration, and liver health can all influence detection time.
Staying hydrated, eating well, and maintaining good liver function may help—but there’s no guaranteed way to speed up the process significantly.
Mitragynine, the main alkaloid, has a half-life of about 24 hours. Full elimination may take 5–6 days depending on usage.
Unlikely. Kratom doesn’t usually cause false positives for opioids or other common substances. However, confirmatory testing may still be used in certain situations.
Kratom’s legal status varies by country and even by state or city in the U.S. Always check local laws before use. See Kratom Restrictions by State for a full breakdown.
