Kratom poisonings soar in US as experts blame synthetic versions and caution against bans | US news

A. Latest Centers for Disease Control and Prevention (CDC) report It shows that kratom poisonings are on the rise in the U.S., but experts say it’s likely due to synthetic derivatives like 7-OH, and blanket kratom bans could harm people who use natural kratom to help manage pain or recover from addiction.

Walter Prozialeck, a professor of pharmacology at Midwestern University, said he was not surprised by the report, which found that kratom-related poisonings have increased by nearly 1,200% over the past decade, with a significant increase in 2025.

This latest increase is almost certainly due to the introduction of 7-hydroxymitragynine, commonly known as 7-OH, a largely synthesized compound found in trace amounts in the kratom leaf.

7-OH has “been marketed as kratom or a superior kratom alkaloid” since its first use in energy drinks and other products around 2024, said Christopher McCurdy, a chemist and pharmacologist at the University of Florida. This means that poison control calls like the one in the CDC report equate the two products. The report itself acknowledges the introduction of 7-OH.

Austin Zamarripa, a professor of psychiatry at Johns Hopkins University, said the difference between the 7-OH natural kratom plant AKA Mitragyna speciosa, a Southeast Asian herb used for centuries as a natural pain reliever, is “arguably the most important scientific distinction right now,” adding: “It’s still underappreciated in public discussions.”

The blurred distinction in marketing creates a “serious consumer safety issue” because 7-OH carries some of the dangers of opioids, including reduced respiratory rate that can lead to severe addiction, withdrawal, and even opioid overdose.

Natural kratom, on the other hand, has been shown to be relatively safe in multiple settings. animal And human studies. In 2018, then-Department of Health and Human Services secretary Brett Giroir said Rejects Drug Enforcement Administration’s proposal to criminalize kratomsaying that the available evidence does not justify schedule I status. The following year, a Food and Drug Administration pilot study in humansKratom, which McCurdy co-authored, showed no serious adverse effects; the main negative symptom was vomiting, which is a proven side effect.

Despite the stark differences between 7-OH and natural kratom, A lot states we implemented or proposed general bans This, which is present in all kratom products, upsets those who see it as a vital medicine. A. latest survey Approximately half of kratom users struggle with chronic pain, and approximately 40% have recovered from addiction.

Many people report using kratom to help them recover from opioid, alcohol, and stimulant addictions. Jeff Maslan, 68, from California, suffers from severe osteoarthritis and has had to undergo regular surgery since his 40s. He has said in the past that he became addicted to opioids after each procedure, which meant he would endure the additional pain of opioid withdrawal. Now Maslan says he uses kratom to counteract these withdrawal symptoms.

Steven, a California resident in his late 40s who has kept his last name, is permanently disabled by a painful heart condition. His oxycodone prescription was canceled without warning after eight years due to new opioid restrictions. The withdrawal was excruciating, especially due to his heart condition.

“I was throwing up my heart pills. I was sweating from extreme pain,” Steven said, adding that he “would do almost anything” to stop it.

Desperate, Steven managed to purchase some kratom. When she took it, “the withdrawal disappeared. My whole body didn’t feel like it was on fire, my skin didn’t crawl.” Unlike opioids, Steven said kratom doesn’t give him any “warm, fuzzy feeling,” it just makes him functional.

While many patients turn to kratom after becoming addicted to opioids they take as prescribed, others use it to curb recreational addictions. Misty Brown, who has advocated for kratom in several state legislatures, said she began buying opioid pills on the street after her pain doctor “fired” her because he suspected she was abusing the prescription. He bought Kratom hoping it would get him high.

“I got into my recovery completely by accident,” he said.

Kratom didn’t intoxicate him as others thought, but Brown said he didn’t feel the urge to call his dealers after taking it. Prozialeck confirmed that natural kratom alone is unlikely to produce a euphoric effect.

FDA officials have previously shipped Zamarripa, McCurdy, and Prozialeck dispute this characterization of natural kratom as an opioid in the past. Conventional opioids carry the risk of overdose through respiratory depression. Studies conducted on rats show that 7-OH carries a risk of respiratory depression in overdose. kratom’s main alkaloid does not do this. According to McCurdy and Prozialeck, kratom activates adrenergic receptors and serotonin receptors, as well as opioid receptors, to which they only partially bind.

This may be why natural kratom is less euphoric than opioids. Prozialeck theorizes that kratom’s interaction with multiple receptors allows it to function like “two drugs at once”: one a partial opioid, the other something akin to the SNRI class of antidepressants; This may be why some users report higher energy with kratom compared to opioids.

There are many reasons why patients may choose kratom over FDA-approved opioid use disorder treatment, including stigma and access barriers, Zamarripa said. While kratom itself is relatively safe, Zamarripa cautioned that there are risks to using it for recovery. Other substances such as fentanyl have also been implicated in fatal poisonings related to kratom. almost universally availablethis may suggest relapse.

“Some people who use kratom may also switch between kratom and stronger opioids, which can increase the risk of overdose,” Zamarripa said, because periods of opioid withdrawal reduce tolerance.

Kratom itself can be addictive, but less so than classic opioids, Prozialeck says. heavy metals Found in some kratom productsZamarripa said it is not yet clear whether these are caused by soil, contaminants or the production and storage process.

Still, Zamarripa thinks natural kratom should be available for purchase.

“These products may offer meaningful benefits to some individuals, and those benefits may be lost if access is restricted too broadly,” he said, adding that “concentrated 7-OH products” likely should be regulated differently.

Steven, who says he now spends much less time in the hospital thanks to kratom, is not sure what to do in case of a ban, but thinks the blanket approach is illogical: “There’s corn on the cob, there’s high fructose corn syrup, there’s whiskey, they’re all made from corn, but they’re all completely different.”
