ratom after Ole Miss student deaths Police have repeatedly said it's still unknown whether the kratom-related products caused or contributed to the student deaths, but the county's drug task force urged people to avoid taking kratom out of an abundance of caution. What they're saying: From the earliest stages of these two separate death investigations, investigators recognized the possibility that illegal or dangerous substances may have been involved, the task force said Wednesday. During the investigations, packaging associated with kratom-related products was discovered at both locations. This information prompted law enforcement to issue a public safety warning out of an abundance of caution. That warning was not a declaration that kratom or any specific substance caused either death. It was a proactive effort to inform the public of a potential danger while investigators worked to determine the facts. What's next: Investigators are still waiting for full toxicology reports to determine their cause of death. Until those results are received and evaluated, we will not speculate about what substances, if any, contributed to these deaths, the task force said. Police say the investigation into the deaths of two University of Mississippi students has brought attention to the important distinction between traditional botanical kratom and manufactured, concentrated or chemically altered kratom-related produc Expand What is kratom? The backstory: Dr. Omer Awan, a radiologist and senior public health contributor for Forbes, said kratom is a plant-based extract that can have varying effects depending on the dose: at low doses it can act as a stimulant, and at higher doses it can act as a sedative. He said people take it for pain relief, to boost their mood and sometimes to treat opiate withdrawal because of its opioid-like effects. The Food and Drug Administration has not approved kratom for any medical use and does not regulate kratom products that are sold in the U.S. The unregulated products are available at retail stores, gas stations and online. They come in powder form, liquid form, capsules, gummies, all sorts of different forms, Awan said in an interview with LiveNow from FOX. Proponents say that in its pure form, kratom is a safe, natural herbal supplement that can help manage pain, anxiety and depression and ease the effects of opioid withdrawal. RELATED: Kratom poisonings spikes, what you need to know about the herbal drug Doctors who treat addiction, however, say people can quickly become dependent on it, leading to withdrawal symptoms. A U.S. Food and Drug Administration webpage is blunt: Don't use it. The agency says it carries the risk of serious adverse effects, including liver toxicity, seizures and substance use disorder. In rare cases, it's been associated with deaths, though kratom was usually used in combination with other drugs in those cases, and the contribution of kratom in the deaths is unclear, the agency says on its website. Kratom is legal at the federal level, but some state and local governments prohibit it. Kratom vs. chemically altered kratom-related products' Dig deeper: Although the FDA's warning against kratom is broad, the drug task force said this week that the Ole Miss student deaths and subsequent kratom warning have brought renewed attention to an important distinction between traditional botanical kratom and manufactured, concentrated or chemically altered kratom-related products. They pointed to a recent action by the U.S. Drug Enforcement Administration that made three synthetic opioid compounds illegal: Mitragynine pseudoindoxyl (MGPI), MGM-15 (dihydro-7-hydroxymitragynine), and MGM-16 (9-fluoro-dihydro-7-hydroxymitragynine). They are minor compounds of kratom that are manufactured as concentrated opioid products, not traditional botanical kratom. These developments raise important questions about how emerging synthetic substances are identified, regulated and prosecuted at the state level, the drug task force said. Families deserve answers. Communities deserve protection. Law enforcement deserves clear, enforceable laws that keep pace with emerging drug threats … We cannot afford to wait for another tragedy before addressing the dangers these substances pose to Mississippians.
