Kratom, an herbal supplement, can cause serious side effects – Insider – INSIDER

  • Kratom, a substance derived from a plant in the coffee family, has been touted to boost mood and energy, relieve pain, and help curb addiction. 
  • A new study has connected self-reported kratom use with a variety of adverse effects, including confusion, vomiting, and, in rare cases, death.
  • Kratom is widely available as powder, capsules, or tea in many states and online and, similar to CBD, not yet been well regulated, making it difficult for users to know the right dose or even what they’re getting. 
  • Researchers say that while there may be therapeutic potential, it’s not a safe substitute for evidence-based treatments.

Kratom, a psychoactive substance derived from a relative of the coffee plant, is a hot trend in the herbal supplement world, marketed to treat everything from addiction to pain to post-traumatic stress disorder.

But kratom’s wide availability and lack of regulation has prompted scrutiny from the medical community — and its use has been linked to serious health issues, according to a new study.

Research published in June in the Pharmacotherapy journal looked at more than 2,000 calls to the National Poison Control Center involving kratom use. Of the 935 calls in which kratom was the only substance involved, the most common symptoms were relatively mild, like agitation and drowsiness. Some people, however, reported vomiting, confusion, and, rarely, seizure, respiratory or cardiac arrest, and, in one case, death.

Among the calls that involved kratom use and other potential toxins, reports of side effects tended to be more severe on the whole. In some cases, kratom users reported seizures or symptoms of psychosis. In three cases, kratom contributed to a death, though other drugs including alcohol, prescription drugs, and cocaine were also involved.

A small subset of patients also reported withdrawal symptoms after using kratom.

“What we found was alarming for something that’s widely available as an herbal supplement,” said pharmacist William Eggleston, lead author of the study and clinical assistant professor at Binghamton University School of Pharmacy and Pharmaceutical Sciences.

The study relied on self-reported data and did not not include how much kratom users had taken.

Kratom has long been used as a medicinal and recreational drug 

Kratom comes from the Mitragyna speciosa plant, which is native to Southeast Asia, where it has a history of use as a medicinal and recreational drug. The plant contains over 50 chemical compounds that could affect the brain and body, but the specifics are largely unknown.

Research suggests that some of the compounds act on opioid receptors as a stimulant in small amounts, but higher doses reportedly reduce pain and cause a sense of well-being, relaxation or sleepiness, according to the Mayo Clinic.

Sold as an herbal supplement online and in smoke shops, kratom has had its share of controversy before: It has been targeted by the U.S. Food and Drug Administration and linked to potential outbreaks of salmonella. The Drug Enforcement Agency tried to classify it as a Schedule I drug (the strictest level of legal restriction for substances ruled to have no recognized medical use and a high potential for abuse) alongside heroin and LSD, but backed off after an unexpected public outcry.

Advocates have said kratom is unfairly targeted, and that it’s safely used by millions of Americans for relaxation or minor pain relief. Even with the current data, the side effects and deaths from kratom appear to pale in comparison with other drugs, including alcohol, the Washington Post reported on an extensive study of kratom users’ experiences.

Kratom’s lack of regulation is part of what makes it potentially dangerous

Kratom, like all herbal supplements, is largely unregulated, making it difficult to be sure what you’re getting or what the proper dose might be, Eggleston said. “These products do not always contain what is advertised,” he said.

In addition, because of the FDA crackdown, sellers have begun to hedge their bets by labeling products “not for human consumption” and declining to offer instructions for use, further increasing the risk that people could ingest a dangerous amount.

But the main concern, Eggleston said, is that we still don’t know enough about kratom. While the two compounds that affect the opioid receptors do so less dramatically than prescription medications or street drugs, making it likely to be safer than most opioids, there isn’t enough research to support its benefits or even advocates’ claims that its safe to use.

“The risk is twofold — we still don’t know how dangerous it potentially is, and we don’t know how effective it is,” Eggleston said, explaining that kratom is often promoted as a cheap alternative to more expensive or less accessible treatments. “There’s a danger that people using kratom for serious medical conditions may be receiving substandard treatment.”

“We’re not saying no one should use kratom or that it should be banned as a Schedule I drug,” he added. “People looking for treatment options deserve a safe, evidence-based treatment and kratom is not there yet.”
