Kratom Addiction: Effects, Dependence, and Treatment
How kratom, a plant with opioid-like effects, can cause dependence and addiction, the signs and symptoms, the health risks, what withdrawal involves, and how treatment and recovery work.
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician and Addiction Medicine Specialist, Phuket Island Rehab.
Kratom is a herbal substance from the leaves of a Southeast Asian tree, Mitragyna speciosa, that can cause dependence and addiction, despite often being sold as a natural or harmless supplement. Its main active compound, mitragynine, acts on the brain’s opioid receptors, producing opioid-like effects such as pain relief, relaxation, and euphoria at higher doses, along with stimulant-like effects of energy and alertness at lower doses. Because it acts on the opioid system, kratom carries a genuine risk of tolerance, physical dependence, and addiction with regular use, and stopping after heavy, prolonged use causes a withdrawal similar to a milder opioid withdrawal. Many people use kratom believing it is a safe natural product or a way to self-treat pain, anxiety, or opioid withdrawal, only to find they have become dependent on it. Kratom also carries real health risks, including liver problems, seizures, and, particularly when combined with other drugs, serious and sometimes fatal reactions. Kratom dependence and addiction are real and treatable, and anyone struggling with it can benefit from medical support, with recovery achievable.
Is kratom addictive?
Yes, kratom can be addictive, despite often being marketed as a natural, harmless herbal supplement. Kratom is a substance made from the leaves of a tropical tree, Mitragyna speciosa, native to Southeast Asia, where it has been used traditionally for centuries. Its main active compound, mitragynine, acts on the brain’s opioid receptors, the same receptors that opioid drugs act on, which is why kratom produces opioid-like effects and, crucially, why it carries a genuine risk of tolerance, physical dependence, and addiction. Many people are surprised by this, because kratom is widely available and often presented as a safe natural product, but its action on the opioid system means it can lead to dependence and addiction much as opioids do.
Understanding kratom addiction matters precisely because the drug’s natural, legal-in-many-places status leads people to underestimate it. People often turn to kratom to self-treat pain, anxiety, low energy, or even opioid withdrawal, believing it to be a safer alternative, only to find they have developed a dependence on kratom itself. This hub explains what kratom is and how it works, why and how it becomes addictive, the signs and symptoms of dependence, the health risks, what withdrawal involves, and how treatment and recovery work. The aim is an honest, accurate understanding of a substance whose natural origins do not make it free of the real risks of dependence and addiction.
What kratom is and how it works
Kratom comes from the leaves of Mitragyna speciosa, a tree in the coffee family native to Thailand, Malaysia, Indonesia, and other parts of Southeast Asia. The leaves are dried and crushed into a powder, brewed as a tea, taken in capsules, or made into extracts and other products, which are widely sold in some countries as supplements, often online or in shops. The leaves contain a number of active compounds, the most important being mitragynine and a related compound, 7-hydroxymitragynine, which act on the brain’s opioid receptors. This opioid-receptor activity is the key to understanding kratom: it is what produces both its effects and its potential for dependence and addiction.
Kratom has a distinctive, dose-dependent effect. At lower doses, it tends to produce stimulant-like effects, increased energy, alertness, sociability, and reduced appetite, which is part of its traditional use by labourers. At higher doses, the opioid-like effects dominate: pain relief, relaxation, sedation, and a sense of euphoria and wellbeing. It is these higher-dose, opioid-like effects, and the relief from pain, anxiety, or opioid withdrawal that kratom can provide, that most often drive regular use and the development of dependence. Because mitragynine engages the opioid receptors, the brain adapts to its presence with repeated use in the same way it adapts to opioids, setting the stage for tolerance, dependence, and addiction. Kratom is therefore best understood as a substance with genuine opioid-like properties, not a harmless herb.

How kratom addiction develops
Kratom addiction develops through the same processes as opioid addiction, because kratom acts on the opioid system. With regular use, the brain adapts to the presence of mitragynine, leading to tolerance, so that more kratom is needed to achieve the same effect. As people use more to overcome tolerance, the brain adapts further, developing physical dependence, so that the body comes to need kratom to feel normal and stopping causes withdrawal. The relief and pleasant effects kratom provides, from pain, anxiety, low mood, or fatigue, reinforce continued use, and for many people this develops into a pattern of compulsive use, cravings, and loss of control that meets the definition of addiction.
A particular pathway into kratom dependence is self-treatment. Many people start using kratom to manage chronic pain, anxiety, or low energy, or specifically to ease opioid withdrawal or replace opioids, believing kratom to be a safer, natural option. Because it does relieve these things, at least at first, regular use easily follows, and dependence develops, so that the person ends up dependent on kratom, sometimes in addition to or instead of their original problem. The wide availability of kratom, its natural image, and the ease of escalating the dose all contribute. Understanding that kratom dependence develops just like opioid dependence, often beginning with well-intentioned self-treatment, helps explain how people find themselves addicted to a substance they believed was harmless.
Signs, symptoms, and health risks
Signs and symptoms of kratom addiction mirror those of other substance addictions: needing more for the same effect, taking kratom more often or in higher doses than intended, being unable to cut down despite wanting to, spending significant time and money obtaining and using it, using it to function or feel normal, experiencing withdrawal between doses, continuing to use despite harm to health, work, or relationships, and craving it. Because kratom is legal in many places and seen as natural, these signs are often missed or minimised, both by users and those around them, which can allow dependence to deepen before it is recognised as a genuine addiction.
Kratom also carries real health risks beyond addiction. Reported harms include liver problems, with some cases of kratom-associated liver injury, seizures, high blood pressure and heart problems, nausea, constipation, and weight loss. Serious and sometimes fatal reactions have occurred, particularly when kratom is combined with other drugs, medications, or alcohol, and many kratom-involved deaths have involved other substances. There are also concerns about the inconsistent strength and purity of kratom products, which are not well regulated, so the amount of active compound can vary widely and products may be contaminated. High doses can cause significant sedation and other dangerous effects. These risks mean kratom should not be regarded as safe simply because it is a plant, and they add urgency to addressing kratom dependence.
Withdrawal and what stopping involves
When someone who has been using kratom heavily and regularly stops, they typically experience a withdrawal similar to a milder form of opioid withdrawal, reflecting kratom’s action on the opioid receptors. Symptoms can include muscle aches and pains, restlessness and agitation, anxiety and irritability, sweating, runny nose and watery eyes, nausea, diarrhoea, insomnia, and strong cravings for kratom, along with low mood. For most people kratom withdrawal is less severe than withdrawal from strong opioids, but it can still be genuinely unpleasant and distressing, and it is a major reason people struggle to stop and return to use. The intensity depends on how much and how long someone has been using.
Because of the withdrawal and the strong cravings, stopping kratom is often best done with support rather than abruptly and alone, particularly for people who have been using high doses for a long time. Medical support can ease the withdrawal symptoms and make stopping more comfortable and more likely to succeed. It is also important, when stopping kratom, to address the reasons it was being used in the first place, such as chronic pain, anxiety, or a previous opioid problem, since leaving those unaddressed makes relapse more likely. Anyone using kratom alongside other substances, or with significant health concerns such as liver problems, particularly needs medical assessment. With support, the withdrawal is manageable and stopping is achievable.
Treatment and recovery
Kratom dependence and addiction are real and treatable, and recovery is achievable. Treatment follows similar principles to the treatment of opioid addiction, given kratom’s opioid-like action. It typically begins with managing withdrawal safely and comfortably, with medical support to ease symptoms. Because kratom acts on the opioid system, in some cases medication-assisted treatment approaches used for opioid addiction may be considered under medical guidance. Counselling and behavioural therapy are central, helping people understand and change the patterns and triggers behind their use, manage cravings, and address the underlying issues, such as chronic pain, anxiety, or a prior opioid problem, that often led to kratom use in the first place. Treatment is tailored to the individual and may be outpatient or residential.
If you or someone you love is struggling with kratom, reaching out for help is a positive step, and it is worth knowing that kratom dependence is a genuine medical issue deserving the same support as any other substance problem, not a personal failing or something that should be dismissed because kratom is natural. Recovery involves getting through withdrawal with support, addressing the reasons behind the use, and building healthier ways to manage pain, stress, or whatever led to kratom in the first place. With proper support, people do recover from kratom addiction and regain their health and wellbeing. However the dependence developed, effective treatment and lasting recovery are achievable, and seeking help is a constructive first step.
Summary
Kratom is a herbal substance from the leaves of a Southeast Asian tree, Mitragyna speciosa, that can cause dependence and addiction, despite often being sold as a natural or harmless supplement. Its main active compound, mitragynine, acts on the brain’s opioid receptors, producing opioid-like effects such as pain relief, relaxation, and euphoria at higher doses, along with stimulant-like effects at lower doses. Because it acts on the opioid system, kratom carries a genuine risk of tolerance, physical dependence, and addiction with regular use, and stopping after heavy, prolonged use causes a withdrawal similar to a milder opioid withdrawal. Many people use kratom believing it is safe or a way to self-treat pain, anxiety, or opioid withdrawal, only to find they have become dependent on it. Kratom also carries real health risks, including liver problems, seizures, and serious or fatal reactions, particularly when combined with other drugs. Kratom dependence and addiction are real and treatable, and anyone struggling with it can benefit from medical support, with recovery achievable.
As Dr. Ponlawat Pitsuwan, addiction medicine specialist at Phuket Island Rehab, puts it, “The biggest problem with kratom is the word natural. People assume a plant cannot be addictive, but mitragynine works on the same opioid receptors as morphine, so the brain adapts to it just like an opioid, and people get dependent, complete with a genuine opioid-type withdrawal when they stop. I see many people who started kratom to get off opioids or to manage pain, and ended up dependent on the kratom instead. It is a real dependence and it deserves real treatment, and the good news is that it responds well to the same approaches we use for opioids.”
Frequently asked questions
Is kratom addictive?
Yes. Although kratom is often marketed as a natural, harmless supplement, its main active compound, mitragynine, acts on the brain’s opioid receptors, the same receptors opioids act on. This is why kratom produces opioid-like effects and why it carries a genuine risk of tolerance, physical dependence, and addiction with regular use. The brain adapts to kratom much as it adapts to opioids, and stopping after heavy use causes a withdrawal similar to a milder opioid withdrawal. Many people develop dependence after starting kratom to self-treat pain, anxiety, or opioid withdrawal, believing it safe. So kratom’s natural origin does not make it free of real addiction risk.
What does kratom do?
Kratom has dose-dependent effects. At lower doses it tends to produce stimulant-like effects: increased energy, alertness, sociability, and reduced appetite. At higher doses, opioid-like effects dominate: pain relief, relaxation, sedation, and euphoria. These effects come from mitragynine acting on the brain’s opioid receptors. People use kratom for energy, to relieve pain or anxiety, to feel euphoric, or to ease opioid withdrawal. It is the higher-dose, opioid-like effects and the relief it provides that most often drive regular use and dependence. Because it engages the opioid system, the brain adapts to it with repeated use, leading to tolerance, dependence, and the potential for addiction.
What is kratom withdrawal like?
Kratom withdrawal resembles a milder form of opioid withdrawal, reflecting kratom’s action on the opioid receptors. Symptoms can include muscle aches, restlessness and agitation, anxiety and irritability, sweating, runny nose and watery eyes, nausea, diarrhoea, insomnia, low mood, and strong cravings. For most people it is less severe than withdrawal from strong opioids, but it can still be genuinely unpleasant and is a major reason people struggle to stop. The intensity depends on how much and how long someone has used. Because of the discomfort and cravings, stopping is often best done with medical support, which can ease symptoms and make stopping more comfortable and more likely to succeed.
Is kratom dangerous?
Kratom carries real health risks beyond addiction. Reported harms include liver problems, with cases of kratom-associated liver injury, seizures, high blood pressure and heart problems, nausea, constipation, and weight loss. Serious and sometimes fatal reactions have occurred, especially when kratom is combined with other drugs, medications, or alcohol, and many kratom-involved deaths have involved other substances. Kratom products are poorly regulated, so their strength and purity vary and they may be contaminated. So kratom should not be considered safe simply because it is a plant. Combining it with other substances is particularly dangerous, and high doses can cause significant sedation and other harmful effects.
Can kratom be used to get off opioids?
Many people use kratom to try to ease opioid withdrawal or replace opioids, because its opioid-like action does relieve withdrawal symptoms. However, this is risky and not a recognised, safe treatment. Because kratom acts on the same opioid receptors, using it this way commonly leads to dependence on kratom itself, so the person swaps one dependence for another, and kratom carries its own withdrawal and health risks. Proper, evidence-based treatment for opioid addiction, using medications such as buprenorphine or methadone under medical supervision, is far safer and more effective. Anyone using kratom to manage an opioid problem would benefit from seeking proper treatment instead.
How is kratom addiction treated?
Treatment follows similar principles to opioid addiction treatment, given kratom’s opioid-like action. It typically begins with managing withdrawal safely and comfortably with medical support, and in some cases medication approaches used for opioid addiction may be considered under medical guidance. Counselling and behavioural therapy are central, helping people change the patterns and triggers behind their use, manage cravings, and address underlying issues such as chronic pain, anxiety, or a prior opioid problem that often led to kratom use. Treatment is tailored to the individual and may be outpatient or residential. Kratom dependence is a genuine, treatable medical issue, and with proper support recovery is achievable.
