Kratom has grown in popularity across the United States in recent years, often marketed as a natural supplement for energy, pain relief, or even as an aid for opioid withdrawal. However, many people are surprised to learn that kratom can remain in the body for days after use and may even be detected on certain drug tests.
On average, kratom can stay in your system for up to 9 days, though this varies depending on factors such as frequency of use, dosage, strain, and your unique metabolism. Understanding how long kratom lingers in the body is essential for anyone concerned about its health effects, dependence risk, or potential detection during a drug screening.
In this guide, we’ll break down everything you need to know about kratom’s effects, elimination time, and the connection between kratom use and recovery.
What Is Kratom and How Does It Work in the Body?
Kratom (Mitragyna speciosa) is a tropical plant native to Southeast Asia. Its leaves contain alkaloids, primarily mitragynine and 7-hydroxymitragynine, which interact with opioid receptors in the brain.
Depending on the dose, kratom can act as a stimulant or a sedative:
- Low doses (1–5 grams) often increase energy, focus, and sociability.
- Moderate doses (5–15 grams) may provide pain relief and mild euphoria.
- High doses (15+ grams) can have sedative effects similar to opioids.
Because of its interaction with opioid receptors, kratom carries a risk of dependence, withdrawal, and misuse. Although marketed as “natural,” it is not risk-free.
Factors That Influence How Long Kratom Stays in Your System
Not everyone metabolizes kratom at the same rate. Several factors determine how long it stays in your body, including:
- Dosage: Larger amounts take longer to break down and eliminate.
- Frequency of use: Regular use leads to accumulation in tissues, extending detection times.
- Strain: Different strains may have varying alkaloid concentrations.
- Age: Older adults may metabolize substances more slowly.
- Weight and body fat percentage: Mitragynine is fat-soluble, meaning it can linger in fatty tissues.
- Metabolism and liver health: A slower metabolism or impaired liver function delays elimination.
- Hydration and diet: Staying hydrated and eating a balanced diet can help the body process substances more efficiently.
Kratom’s Half-Life: Understanding Elimination Time
The half-life of a substance refers to the amount of time it takes for half of it to leave the body.
Studies suggest that mitragynine has a half-life of about 24 hours, meaning it can take approximately one full day for the concentration in the body to reduce by half.
Complete elimination typically takes five to six half-lives, which explains why kratom can remain in the system for up to 5–9 days, depending on use patterns.
How Long Is Kratom Detectable in Urine, Blood, Saliva, and Hair?
Different drug tests can detect kratom for varying lengths of time:
- Urine: Kratom is most commonly tested for in urine. It can typically be detected for up to 7 days, though heavy users may test positive for longer.
- Blood: Kratom is detectable in blood for a shorter period, usually 1–3 days.
- Saliva: Limited research exists, but saliva tests may detect kratom for up to 24 hours.
- Hair: Like most substances, kratom could be detected in hair for up to 90 days, though hair testing for kratom is uncommon.
Most standard workplace drug tests do not screen for kratom, but specialized tests can detect it if requested.
How Different Strains and Dosages Affect Detection Time
Kratom comes in several strains—such as red vein, green vein, and white vein—each with slightly different effects and alkaloid content.
- Red vein strains are typically more sedating and may linger longer due to higher alkaloid levels.
- White vein strains are more stimulating and may metabolize slightly faster.
- Green vein strains fall somewhere in between.
Dosage is also critical:
- Occasional low-dose users may clear kratom in a few days.
- High-dose or chronic users may have detectable traces for over a week.
How Frequent Use Impacts Kratom Accumulation in the Body
One-time or occasional use of kratom is less likely to lead to prolonged detection times. However, frequent or daily use can cause the substance to accumulate in fatty tissues and organs.
Over time, the body becomes less efficient at processing kratom, and traces may remain detectable for longer periods. This is why chronic users are at a higher risk of prolonged elimination times, withdrawal symptoms, and dependence.
Can You Speed Up the Elimination of Kratom?
Many people wonder if they can “flush” kratom out of their system faster. While you cannot drastically accelerate the body’s natural processes, some steps may help:
- Stay hydrated: Drinking water supports kidney function and urine excretion.
- Exercise: Physical activity can boost metabolism and fat breakdown.
- Eat a healthy diet: A diet rich in fiber, fruits, and vegetables aids digestion and detoxification.
- Avoid additional use: The only sure way to shorten detection time is to stop consuming kratom.
However, no quick fix exists—time is the most reliable factor in kratom elimination.
Symptoms of Kratom Withdrawal and Tapering Off
Because kratom interacts with opioid receptors, regular use can lead to physical dependence. Withdrawal symptoms may occur within 12–48 hours after the last dose and can last for about a week.
Common withdrawal symptoms include:
- Muscle aches
- Irritability
- Insomnia
- Sweating and chills
- Cravings
- Anxiety or depression
A gradual tapering schedule, overseen by a healthcare provider, can reduce withdrawal severity and make it easier to quit safely.
How Long Do the Effects of Kratom Last?
The effects of kratom are relatively short-lived compared to how long it stays in the body.
- Low doses: Effects usually last 3–4 hours.
- Moderate to high doses: Effects may last 5–6 hours.
This contrast between short-term effects and long-term detectability explains why someone may feel “sober” but still test positive for kratom days later.
Drug Tests and Kratom: Will It Show Up?
Standard 5-panel drug tests used by most employers do not screen for kratom. However, certain advanced tests can detect mitragynine specifically.
Kratom may also raise concerns in legal or medical situations where specialized testing is ordered. Even if not tested for directly, kratom’s effects can mimic opioids, which may create complications for those in treatment or recovery.
Is Kratom Legal and Regulated in the U.S.?
Kratom’s legal status in the United States is complex.
- Federally: Kratom is not currently a controlled substance, though the DEA has considered scheduling it.
- State-level bans: Some states, such as Alabama, Indiana, and Wisconsin, have banned kratom.
- Local laws: Certain counties and cities also restrict kratom sales.
Because kratom is not regulated by the FDA, its purity and potency are inconsistent, raising additional safety concerns for users.
Seeking Help for Kratom Dependence or Misuse
For some people, occasional kratom use may not cause problems. But for others, kratom use can spiral into dependence, withdrawal, and difficulty quitting.
If you find yourself relying on kratom daily, struggling with cravings, or experiencing withdrawal when you stop, it may be time to seek professional help. Treatment options include:
- Medical detox for safe withdrawal management.
- Outpatient and inpatient rehab programs for structured support.
- Therapy and counseling to address underlying mental health conditions.
- Sober living communities to support long-term recovery.
