How Long Does Kratom Last? A Comprehensive Guide

Kratom, also known by its scientific name, Mitragyna speciosa, is a tropical evergreen tree native to Southeast Asia. People have used this plant for centuries in traditional medicine and for recreational purposes due to its properties.

As mitragyna speciosa gains global popularity, many people are curious about the duration of its effects. When it comes to speciosa, one of the most common questions people have is how long its effects last after consumption. Additionally, many individuals are curious about how long kratom remains detectable in the body. This article aims to provide a detailed and comprehensive overview of kratom’s duration and related considerations.

Firstly, let’s explore the immediate effects of kratom. After consuming it, the onset of its effects can vary depending on factors such as the strain, dosage, and individual metabolism. Generally, kratom’s effects can be felt within 10 to 30 minutes, with peak effects occurring around 1 to 1.5 hours after ingestion. These effects typically last for about 3 to 6 hours, but this can also vary from person to person.

It is important to note that the duration and intensity of kratom’s effects can be influenced by various factors. For instance, higher doses of speciosa tend to have longer-lasting effects compared to lower doses. Additionally, the strain of speciosa used can also impact the duration of its effects. Some strains are known for their longer-lasting effects, while others may provide a more short-lived experience.

Moving on to the detection of kratom in the body, it is crucial to understand that kratom’s alkaloids, the active compounds responsible for its effects, can be detected through various drug tests. However, the detection window for speciosa can vary depending on the type of test being conducted.

In urine tests, kratom can typically be detected for up to 7 days after consumption. However, this detection window may be shorter for infrequent users or those who have consumed lower doses. It is worth noting that kratom’s metabolites can be detected in urine tests, rather than the actual presence of kratom itself.

In blood tests, kratom’s detection window is relatively shorter, usually ranging from 24 to 48 hours after consumption. This means that speciosa is less likely to be detected in blood tests compared to urine tests.

Hair tests, on the other hand, have a longer detection window for kratom. Mitragynine metabolites can be detected in hair follicles for up to 90 days after consumption. This makes hair tests a more reliable method for detecting speciosa use over an extended period.

It is important to keep in mind that the detection of kratom in drug tests may also depend on the specific test’s sensitivity and the frequency of speciosa use. Additionally, it is worth noting that kratom’s legality and regulations vary across different countries and regions.

How Long Do the Effects of Kratom Last?

The effects of kratom largely depend on various factors, including the strain, dosage, and individual differences among users. In general, however:

Onset: Users usually begin to feel the effects of kratom within 10-15 minutes of ingestion, though this can be faster with more potent strains or larger doses.

Peak Effects: Mitragyna Speciosa’s peak effects are typically observed between 1 to 2.5 hours after consumption.

Duration: On average, the effects of kratom can last anywhere from 3 to 6 hours. This range can be influenced by the user’s metabolism, tolerance, and the specific strain consumed.

Different Strains, Different Durations

Mitragyna Speciosa comes in various strains, each with its unique profile of effects:

White Strains: White Vein Kratom known for it’s energizing effects, may not last as long as other strains, typically around 3-4 hours.

Red Strains: Red Vein Kratom is recognized for it’s relaxing properties, the effects of red strains can last anywhere from 4-6 hours or more.

Green Strains: Green Vein Kratom strains offer a balance between energy and relaxation, and their effects typically last around 4-5 hours.

Factors Influencing Kratom’s Duration

Dosage: A higher dose might produce longer-lasting effects. However, it’s crucial to consume mitragyna speciosa responsibly, as excessive consumption can lead to negative side effects or increased tolerance.

Tolerance: Regular and frequent users might find the effects of kratom diminish over time, requiring larger doses to achieve the same results. This can potentially shorten the effective duration of the speciosa experience.

Method of Consumption: Mitragyna Speciosa can be consumed in various ways, including chewing leaves, brewing tea, or taking capsules. The mode of intake can influence how quickly the body absorbs and processes mitragyna speciosa.

How Long Does Kratom Stay in the System?

For those concerned about drug testing or other reasons, understanding how long kratom remains detectable in the body is crucial.

Half-life: The primary alkaloid in mitragyna speciosa, mitragynine, has a half-life of approximately 24 hours. This means it takes about a day for half of the ingested speciosa to leave your system.

Detection: While kratom isn’t commonly screened for in standard drug tests, specialized tests can detect its metabolites. Based on the half-life, traces of mitragynine can potentially remain in the system for several days after use. Some estimates suggest speciosa can be detected for up to 9 days, though this can vary based on metabolism, age, body fat, and other factors.

Storing Kratom for Longevity

If you’re a kratom consumer, it’s essential to store your product correctly to maintain its shelf life and potency. Keep it in a cool, dark place away from moisture and sunlight. Sealed containers or zip-lock bags can help keep it fresh and potent for longer.


Mitragyna Speciosa’s duration in the body, both in terms of effects and detectability, varies depending on several factors. For the best experience, it’s essential to use mitragyna speciosa responsibly and be informed about its potential impacts and duration. Always start with a lower dose if you’re new to it, and pay attention to how your body responds. Remember that while mitragyna speciosa has its benefits, it’s essential to approach its use with care and respect.
