How Long Does Kratom Stay in Your System?

Knowing about kratom, its half-life, how it affects people, and other information about the herbal extract can help you determine how long does kratom stay in your system.

Since it can produce widely varying side effects, kratom is an unusual substance. Taking small amounts of this herbal extract can stimulate the body. When that happens, people might be more alert, energetic, and social.

On the other hand, using large amounts of kratom can produce symptoms similar to the effects of opioid drugs. That is, it can sedate people, reduce physical pain, and produce pleasure.

How Long Does Kratom Stay in Your Urine?

To discuss how long is kratom detectable in urine or persists in the body, it might be helpful to discuss the half-life of kratom’s ingredients. A half-life is the amount of time it takes for half of a substance to leave a person’s body. For example:

  • One ingredient in kratom, mitragynine, has a half-life of around 3.5 hours.
  • Another kratom ingredient, 7-hydroxymitragynine (7-HMG), has a half-life of around 2.5 hours.

Given these factors, a kratom half-life would probably be around 2.5 to 3.5 hours. If it takes that long for half the amount of ingested kratom to leave someone’s body, kratom could affect someone’s body for five to seven hours.

Does Kratom Show Up in a Drug Test?

It depends on whether kratom shows up in a drug test. Mostly, the results depend on the type of drug screening.

Toxicology screenings look for the presence of drugs, alcohol, or other substances in the body. For many toxicology screenings, there is no kratom drug test detection time. Many tests can’t detect kratom because there aren’t tests specifically designed to spot the substance in people’s bodies.

But even though there aren’t kratom drug tests, urinalysis (urine tests) can detect the presence of kratom. These tests typically spot the presence of kratom after it’s been in the body for about six hours or so.

Why Is Kratom Dangerous?

Since kratom is a herbal extract that’s legal in many places and isn’t detectable by many types of toxicology screenings, people might think that it’s safe.

Actually, kratom can produce dangerous side effects, such as high blood pressure (hypertension) and seizures. Like other substances, people might become dependent on kratom, use larger amounts of it, and experience further harm.
