Kratom, derived from the tropical tree Mitragyna speciosa native to Southeast Asia, is a plant-based substance. Its leaves contain compounds with various effects, and people consume kratom in different forms, including powders, capsules, or brewed teas.
Understanding Kratom Detection
Kratom’s primary active compounds are alkaloids, notably mitragynine and 7-hydroxymitragynine. The body metabolizes these compounds into byproducts detectable in biological samples. While these alkaloids interact with opioid receptors, they are chemically distinct from traditional opioids.
Standard drug tests, such as common 5-panel screens, are not designed to identify kratom alkaloids. Detecting kratom generally requires specialized testing panels that specifically look for its unique alkaloids and their metabolites.
Factors Affecting Detection Time
Several individual characteristics and usage patterns influence how long kratom remains detectable in a person’s system. An individual’s metabolic rate plays a significant role, as faster metabolisms can process and eliminate substances more quickly. This rate can be affected by factors like age, with older individuals generally processing substances more slowly.
The dosage and frequency of kratom use also directly impact detection times; higher doses and more consistent, long-term use typically result in longer detection windows. Body composition, specifically a higher body fat percentage, may cause kratom metabolites to linger longer in the system. Additionally, the overall health of the liver and kidneys, which are responsible for detoxification and elimination, can affect how quickly kratom is cleared from the body.
Common Drug Test Types and Detection Windows
Different drug test types have varying detection windows for kratom and its metabolites. Urine tests are a common method and can typically detect kratom for approximately 2 to 9 days after last use. The detection in urine can begin as early as six hours post-ingestion.
Blood tests offer a shorter detection window, generally identifying kratom for a few hours up to 1-2 days. Hair follicle tests have the longest detection period, with estimates suggesting kratom could be detectable for up to 90 days. Saliva tests typically have a shorter detection window, usually ranging from hours to 1-4 days.
Is Kratom Commonly Screened For?
Kratom is not routinely included in standard drug screening panels, such as the common 5-panel or 10-panel tests used by many employers. These standard tests are designed to detect federally regulated substances like marijuana, cocaine, opioids, and amphetamines. Kratom’s unique alkaloids, mitragynine and 7-hydroxymitragynine, are not typically sought in these screens.
Detection of kratom usually requires a specialized, extended drug panel or a specific request from the testing authority. While kratom is federally legal, its legal status varies by state and locality, which can influence whether it is included in drug testing policies in specific contexts like some pain management clinics, certain employers, or legal cases.
