Kratom comes from the leaves of Mitragyna speciosa, a tree native to Southeast Asia with a long history as a traditional remedy and work aid. In the United States, kratom is sold as a botanical product, not as an approved drug or dietary supplement — the FDA has determined it isn’t lawfully marketed as a drug product, a dietary supplement, or a food additive, and the agency has told consumers not to use it for medical treatment. That regulatory gap is exactly why “why do people use it anyway?” is worth asking directly: understanding the reasons people report, and where that self-reported picture runs out, is the useful first step before anyone decides what to do with a kratom product.
This isn’t a guide to how to take kratom, how much to take, or which form works best. It’s a plain look at what researchers and regulators have documented about why people say they use it.
What People Report, and What That Does — and Doesn’t — Tell Us
According to the National Institute on Drug Abuse (NIDA), people who use kratom most often report doing so to manage pain, to ease symptoms of anxiety or depression, to help with fatigue, and to manage cravings or withdrawal tied to opioid or other substance use. Most people who use kratom give more than one reason, not a single motivation. The FDA’s public information lines up with this: people self-treat pain, coughing, diarrhea, anxiety, depression, opioid use disorder, and opioid withdrawal with kratom products.
That word — report — matters. Both agencies are describing what people say about their own experience, not confirming that kratom caused the result.
Why Do People Use Kratom for Pain?
Pain is one of the most frequently cited reasons. Researchers point to kratom’s two best-studied compounds, mitragynine and 7-hydroxymitragynine, which act on the same mu-opioid receptors in the brain as opioid medications, with mitragynine also affecting serotonin, dopamine, and norepinephrine activity. That receptor activity is the working theory behind why some people associate kratom with pain relief.
NIDA is direct about the ceiling on that explanation: kratom has not been proven safe or effective for any medical condition, including pain. The receptor science describes a plausible mechanism — it does not confirm a clinical benefit.
Why Is Kratom Used for Energy?
The energy association goes back centuries, to kratom’s traditional use in Southeast Asia by laborers who chewed the leaves to stay alert through the workday. NIDA notes that people today report both stimulant-like effects — increased energy, alertness, a faster heart rate — and, separately, opioid- and sedative-like effects such as relaxation and pain relief. Some of the research literature on kratom use describes smaller amounts being associated with more stimulant-like reports and larger amounts with more sedative-like reports, but NIDA notes plainly that this pattern hasn’t been confirmed by controlled study — it’s an observation from self-reported use, not an established dose-response relationship.
Are Self-Reports the Same as Clinical Evidence?
No. Self-reported reasons come from surveys, online communities, and case reports — people describing their own experience and motivation. That’s useful for understanding behavior and for pointing future research in the right direction, which is how NIDA uses it. It is not the same as a controlled clinical trial measuring an outcome against a placebo.
NIDA states this directly: while research into kratom’s potential therapeutic uses is ongoing, kratom products have not been demonstrated to be safe and effective for any medical condition. The DSM-5 — the reference clinicians use to diagnose substance-related conditions — doesn’t even include a specific kratom-use diagnosis yet, which gives a sense of how early the formal clinical picture is compared to the volume of self-reported use.
What the Evidence Cannot Tell Us Yet
- Effects vary by product and person. NIDA notes that kratom’s effects depend on the amount taken, the product’s potency and formulation, how it’s consumed, other substances in a person’s system, and individual medical history — which makes any single “why it works” explanation hard to generalize.
- Product content isn’t guaranteed. The FDA and NIDA have both documented kratom products contaminated with heavy metals or bacteria such as Salmonella, meaning a reported effect isn’t always attributable to kratom alone.
- Long-term effects remain understudied. NIDA states there’s little evidence on how regular, long-term kratom use affects someone over time, though case reports have linked heavy long-term use to serious liver problems in a small minority of users.
- Serious adverse effects have been documented. The FDA has warned of risks including liver toxicity, seizures, and substance use disorder associated with kratom use. Both agencies note that most kratom-involved deaths occurred alongside other drugs, which makes kratom’s specific contribution difficult to isolate.
None of this settles whether kratom “works” for any individual’s reason for using it. It marks where self-report ends and where verified clinical science hasn’t yet caught up.
Appropriate Next Step
If you’re trying to understand why kratom comes up in conversations about pain, energy, mood, or opioid withdrawal, the honest answer is: because people report using it for those reasons, and researchers are actively studying whether any of that reported experience holds up under clinical scrutiny. It isn’t an approved treatment for any of them.
Anyone weighing kratom against a specific health concern — particularly pain management, a mental health condition, or opioid withdrawal — is better served by having that conversation with a qualified healthcare provider who knows their full medical picture than by relying on a botanical product with an unsettled safety and efficacy record.
