Fatal case links concentrated 7-HMG kratom product to opioid toxidrome

A case report describes a 42-year-old man found dead at home after ingesting three tablets of a commercial 7-hydroxymitragynine (7-HMG) product along with beer. Postmortem findings including pulmonary edema and toxicology showing 37.3 ng/mL 7-HMG and 76 ng/mL mitragynine pseudoindoxyl in blood were, per the report, most consistent with a fatal opioid-like toxidrome; the authors note the ingested dose delivered roughly 87 mg 7-HMG, an estimated 19- to 87-fold higher 7-HMG exposure than typical dried kratom leaf powder.

Most relevant for: Patients using concentrated or chemically processed kratom alkaloid products marketed as 7-hydroxymitragynine, as distinct from traditional kratom leaf preparations.
