Notes from the Field: Unintentional Drug Overdose Deaths with Kratom Detected 27 States, July 2016 December 2017
Kratom (Mitragyna speciosa) a plant native to Southeast Asia, contains the alkaloid mitragynine, which can produce stimulant effects in low doses and some opioid like effects at higher doses when consumed (1) Use of kratom has recently increased in popularity in the United States, where it is usually marketed as a dietary or herbal supplement (1) Some studies suggest kratom has potential for dependence and abuse (1,2) As of April 2019, kratom was not scheduled as a controlled substance. However, since 2012, the Food and Drug Administration has taken a number of actions related to kratom, and in November 2017 issued a public health advisory* in addition, the Drug Enforcement Administration has identified kratom as a drug of concern. During 2011 2017, the national poison center reporting database documented 1,807 calls concerning reported exposure to kratom (3) To assess the impact of kratom, CDC analyzed data from the State Unintentional Drug Overdose Reporting System (SUDORS) CDC funds 32 states and the District of Columbia to abstract into SUDORS detailed data on unintentional and undetermined intent opioid overdose deaths from death certificates and medical examiner and coroner reports, including postmortem toxicology results. Although kratom is not an opioid, overdose deaths involving kratom (including nonopioid overdose deaths) are included in SUDORS.SS Although postmortem toxicology testing varies in scope among medical examiners and coroners, SUDORS records all substances detected on postmortem toxicology testing, along with overdose specific circumstances. CDC analyzed overdose deaths in which kratom was detected on postmortem toxicology testing and deaths in which kratom was determined by a medical examiner or coroner to be a cause
