Kratom has surged in popularity across the United States, sold in gas stations, smoke shops, and online as a natural remedy for pain, fatigue, anxiety, and even opioid withdrawal. Because it comes from a plant and is often marketed as a wellness supplement, many people assume it is harmless. The reality is more complicated. Kratom side effects range from mild and uncomfortable to serious, and its opioid-like properties carry a real risk of dependence. Understanding what kratom actually does in the body is essential before deciding whether it belongs in your life. At Ray of Hope in Columbus, our outpatient programs, including our Intensive Outpatient Program, help people who have developed a dependence on kratom and other substances.
What Is Kratom?
Kratom comes from the leaves of Mitragyna speciosa, a tropical tree native to Southeast Asia, where it has traditionally been chewed or brewed as tea. Its effects come from active compounds called alkaloids, primarily mitragynine and 7-hydroxymitragynine, which interact with some of the same brain receptors targeted by opioids.
What makes kratom unusual is that its effects can depend heavily on the dose. At lower amounts, it may act as a mild stimulant, producing alertness and energy. At higher amounts, sedation and pain relief may become more prominent, much like an opioid, although effects vary widely by person and product. In the U.S., kratom is commonly sold as a powder, in capsules, as an extract, or in concentrated products. This dual nature, combined with inconsistent product quality, is part of what makes its risks unpredictable.
Common Kratom Side Effects
Kratom can produce a range of unwanted effects. Many users experience these kratom adverse effects without realizing the substance is the cause. Reported side effects include:
- Nausea and vomiting
- Constipation
- Dry mouth
- Itching and sweating
- Dizziness or drowsiness
- Reduced appetite
- Increased urination
With prolonged or heavy use, some people may also experience weight loss. While these symptoms are often mild, some may persist or recur with regular use. For some people, they are the first sign that kratom is affecting the body more than expected.
More Serious Kratom Risks
Beyond the everyday discomforts, kratom carries more significant dangers, especially with frequent or heavy use. This is where the question of kratom risks becomes serious.
Dependence and Addiction
Because kratom acts on opioid receptors, the body can become physically dependent on it. Over time, some users may develop tolerance, needing more to achieve the same effect, and may find it difficult to reduce or stop their use. Understanding the line between physical dependence and addiction is important, a topic explored in our article on the difference between addiction and dependence.
Withdrawal
People who stop using kratom after frequent or prolonged use may experience withdrawal symptoms that resemble opioid withdrawal. These can include muscle aches, insomnia, irritability, anxiety, runny nose, sweating, and mood swings. Because some of these symptoms overlap with opioid withdrawal, our guide on the signs of opioid withdrawal is a useful reference for what to expect.
Liver and Other Health Concerns
Kratom use has been linked to rare cases of acute liver injury, along with rapid heart rate, high blood pressure, confusion, slow breathing, and, in rare reports, seizures. The risk of serious harm appears greater when kratom is combined with other substances such as alcohol, benzodiazepines, or opioids. Most reported kratom-associated deaths have involved additional substances, although kratom’s precise contribution is not always clear. Product contamination is another concern, since unregulated kratom has at times been found to contain heavy metals, bacteria, or other adulterants.
Is Kratom Safe? What the Science and Regulators Say
So, is kratom safe? The honest answer is that this remains an area of significant concern among health authorities. The U.S. Food and Drug Administration has not approved kratom for any medical use and has repeatedly warned the public about its risks, including the potential for addiction and serious harm. There are no legally marketed prescription or over-the-counter drugs containing kratom.
Much of the recent regulatory attention has focused on concentrated and semi-synthetic products containing high levels of 7-hydroxymitragynine, or 7-OH, which can have greater potency at mu-opioid receptors than morphine. As of July 2026, the DEA has filed notices of intent to temporarily place 7-OH above a specified concentration and three related substances into Schedule I. The action targets concentrated or synthetic products, not botanical kratom containing naturally occurring 7-OH below the specified threshold. The legal status of natural, botanical kratom continues to vary by state and locality. In short, kratom exists in a shifting legal gray area, and “natural” does not mean risk-free.
For anyone asking if kratom is dangerous, the safest conclusion is that the risks are real and not fully understood, particularly with concentrated products and long-term use.
Kratom Side Effects at a Glance
The table below organizes the main kratom side effects by category to give a clearer overview of what to watch for.
| Category | Effects |
|---|---|
| Commonly reported side effects | Nausea, constipation, dry mouth, dizziness, drowsiness, sweating, itching, and appetite changes |
| Serious reported risks | Dependence, rare liver injury, rapid heart rate, high blood pressure, slow breathing, confusion, and seizures |
| Withdrawal symptoms | Muscle aches, insomnia, irritability, anxiety, sweating, runny nose, fatigue, and mood swings |
| Higher-risk situations | Mixing kratom with other substances, using concentrated or enhanced 7-OH products, and consuming contaminated or mislabeled products |
Seeing the full range side by side helps clarify that kratom’s effects extend well beyond the mild, natural image it is often given.
Signs Kratom Use Has Become a Problem
For many people, kratom use starts as an attempt to manage pain, energy, anxiety, or withdrawal from other substances. It can gradually turn into a dependence of its own. Warning signs that kratom use may have become a problem include:
- Needing more kratom to feel the same effect
- Experiencing withdrawal symptoms when not using
- Trying to quit but being unable to
- Regularly relying on kratom to cope with stress or emotions, especially when it becomes difficult to function without it
- Spending significant time or money obtaining it
- Continuing use despite negative effects on health or life
When substances are used to manage underlying emotional struggles, addressing both together is key, as discussed in our overview of the connection between mental health and substance abuse.
Getting Help
If kratom has taken a larger role in your life than you intended, know that help is available and recovery is very possible. Because kratom affects opioid receptors, treatment may draw on approaches used for opioid dependence, combining medical assessment and support for withdrawal with therapy that addresses the reasons a person started using in the first place. There is no FDA-approved medication specifically for kratom use disorder, although clinicians may use medications off-label in selected cases. Our article on the harsh reality of opioid addiction speaks to both the challenge and the hope of recovery.
For many people, outpatient care offers the right balance of structure and flexibility, allowing them to receive consistent treatment while staying connected to work, home, and family. You can learn more in our overview of the benefits of intensive outpatient programs.
At Ray of Hope in Columbus, our outpatient services include individual therapy, group therapy, and structured programming through our Intensive Outpatient Program. Our team helps people address kratom dependence and build healthier tools for managing pain, stress, and emotions. Reaching out is the first step toward feeling like yourself again.
Kratom Side Effects: Frequently Asked Questions
Is Kratom Addictive?
Kratom can be addictive. Its alkaloids interact with some of the same receptors targeted by opioids, so regular use can lead to tolerance, physical dependence, withdrawal, and, in some people, a substance use disorder. People who stop after consistent use may experience opioid-like withdrawal symptoms, which is one of the clearest signs that the body has become dependent on the substance.
What Are the Most Common Kratom Side Effects?
Commonly reported side effects include nausea, constipation, dry mouth, dizziness, drowsiness, sweating, itching, and appetite changes. While often mild, these can persist with regular use. Rare but serious reported risks include liver injury, seizures, slow breathing, and substance use disorder.
Is Kratom Legal and Safe to Use?
Botanical kratom’s legal status varies by state and locality. In July 2026, the DEA filed notices of intent to temporarily schedule 7-OH above a specified threshold and certain related substances, while excluding botanical kratom below that threshold. The FDA has not approved kratom for any medical use and warns of real risks, including dependence, liver toxicity, seizures, and contaminated products. “Natural” does not mean safe, and the dangers are not yet fully understood.
