Yes, you can become addicted to kratom. Its active compounds bind to the same brain receptors as opioid drugs, and with regular use, your body can develop tolerance and physical dependence. In a large survey of over 2,000 kratom consumers, about 25.5% met the clinical criteria for kratom use disorder. That said, kratom’s addiction potential is generally lower than that of traditional opioids like morphine or fentanyl, and most people who do develop dependence experience it in a mild to moderate form.
How Kratom Acts on the Brain
Kratom contains two key alkaloids that interact with opioid receptors. The primary one, mitragynine, makes up the bulk of kratom’s alkaloid content but has relatively low binding affinity at the mu-opioid receptor, the same receptor targeted by morphine and fentanyl. Its binding strength is roughly 89 times weaker than morphine’s at that receptor. The second compound, 7-hydroxymitragynine, is present in much smaller quantities but binds about nine times more strongly than mitragynine and acts as a partial activator of the mu-opioid receptor.
That word “partial” matters. Traditional opioids like morphine fully activate the receptor and also trigger a secondary signaling pathway linked to tolerance, respiratory depression, and constipation. Mitragynine appears to activate the receptor in a biased way, stimulating one signaling pathway while largely skipping the other. This is why kratom tends to produce milder side effects and lower overdose risk compared to conventional opioids. But partial activation is still activation. With repeated dosing, the brain adapts to the presence of these compounds, and that adaptation is the foundation of physical dependence.
What Dependence and Withdrawal Feel Like
People who use kratom frequently and then stop often report withdrawal symptoms within a day or so. Some of these symptoms overlap with opioid withdrawal: runny nose, muscle aches, diarrhea, and watery eyes. Others resemble withdrawal from stimulants or sedatives, including lethargy, depressed mood, anxiety, and insomnia. The combination makes sense because kratom has both stimulant-like and opioid-like effects depending on the dose.
The good news is that kratom withdrawal is consistently described as milder than withdrawal from opioids, sedatives, or stimulants. Some researchers have compared the experience to quitting heavy coffee use. Most people who report dependence or withdrawal find it tolerable and manageable without medical intervention. That doesn’t mean it’s trivial, especially for heavy, long-term users, but it’s a meaningfully different experience from the severe withdrawal associated with heroin or prescription painkillers.
How Common Is Kratom Addiction?
A 2024 study in the Journal of Addiction Medicine surveyed 2,061 kratom consumers and found that 25.5% met the criteria for kratom use disorder based on a checklist adapted from the standard psychiatric diagnostic manual. The two most common symptoms were tolerance (reported by 81.3% of those who qualified) and withdrawal (68.0%). Most of these individuals fell into the mild or moderate category rather than severe.
People with a history of another substance use disorder were nearly three times more likely to meet the criteria for kratom use disorder. This suggests that if you’ve previously struggled with alcohol, opioids, or other substances, your risk of developing problematic kratom use is substantially higher.
Dose Frequency Matters More Than Amount
One of the clearest findings from recent research is that how often you use kratom is a stronger predictor of dependence than how much you take in a single dose. A 2024 study found that withdrawal symptoms and other signs of use disorder were more closely tied to dosing frequency than to the size of each dose. In other words, taking kratom three or four times a day carries more risk than taking a larger dose once or twice, even if the total amount consumed is similar.
Studies of chronic kratom users in Malaysia found a similar pattern: consuming three or more servings of kratom tea daily was associated with more severe withdrawal. Greater weekly dosing frequency was also linked to higher odds of endorsing each of the 10 individual symptoms used to diagnose kratom use disorder, including cravings, using more than intended, and continuing use despite negative consequences.
Kratom vs. Traditional Opioids
Kratom occupies an unusual middle ground. It activates opioid receptors enough to produce pain relief, mood elevation, and physical dependence, but it does so more weakly and through a slightly different mechanism than drugs like morphine or oxycodone. Animal studies show that kratom’s main alkaloid causes less tolerance, less respiratory depression, and less gut slowdown than equivalent pain-relieving doses of morphine. In mice, mitragynine did not produce the reward-seeking behavior typically seen with addictive opioids, though 7-hydroxymitragynine did show some rewarding effects.
This profile is why some people use kratom to manage chronic pain or to taper off stronger opioids. It’s also why the addiction picture is complicated. Kratom is not as dangerous as heroin or fentanyl, but it is not harmless either. The FDA has warned consumers about the risk of substance use disorder, liver toxicity, and seizures associated with kratom use. There are no FDA-approved kratom products on the U.S. market, and as of late 2024, a full human study on kratom’s abuse potential had not yet been completed.
Treatment for Kratom Dependence
There is currently no established, evidence-based protocol specifically for treating kratom addiction. In practice, clinicians often borrow from opioid addiction treatment. The most commonly reported approaches include buprenorphine (the same medication widely used for opioid use disorder) and clonidine, which helps manage withdrawal symptoms like anxiety and elevated heart rate.
Published case reports describe successful outcomes with buprenorphine-based treatment over roughly six months, with patients experiencing only mild symptoms like a runny nose and some fatigue during the process. Because kratom withdrawal is generally milder than opioid withdrawal, many people manage to quit without medication, tapering their dose gradually over weeks. For heavier users or those with a history of other substance use disorders, medical support can make the process smoother and reduce the risk of relapse.
Who Is Most at Risk
Not everyone who tries kratom will develop a problem. The people most likely to develop dependence share a few characteristics: they dose multiple times per day, they’ve used kratom consistently for months or years, and they have a history of other substance use disorders. The roughly three-quarters of users in the large survey who did not meet criteria for kratom use disorder suggest that occasional or moderate use carries lower risk, though individual responses vary.
If you’re using kratom daily and notice that you need more to get the same effect, or that you feel physically uncomfortable when you skip a dose, those are the early signs of dependence. Tolerance and withdrawal are the most common entry points, and they tend to develop before the behavioral symptoms like cravings and loss of control.
