Kratom can generally be detected in urine for about 5 to 7 days after use. Some sources suggest it might be detectable for up to 9 days depending on the specific test and individual factors like dosage, metabolism, and frequency of use. Specialized drug tests that look specifically for kratom alkaloids (mitragynine and 7-hydroxy mitragynine) are required as standard drug tests do not typically screen for kratom.
Key Points on Kratom Detection in Urine:
- Detectable in urine roughly 5 to 7 days after last use, sometimes up to 9 days with sensitive tests.
- Standard drug tests don't usually detect kratom; specialized laboratory tests are needed.
- Detection times depend on dose, metabolism, frequency of use, and individual physiology.
- Metabolites of kratom may linger in urine beyond the active drug presence.
- The half-life of kratom’s main alkaloid (mitragynine) varies but is roughly around 24 hours on average.
Thus, kratom stays in urine detectable form for about a week, but this can vary depending on many factors. This summary is based on recent studies and drug testing data available as of 2025.
