The Times requested Florida autopsy reports citing kratom or one of its major chemical compounds, an alkaloid called mitragynine, as a cause of death or contributing factor dating back to 2010.
No news organization has ever done this on a large scale. The requests initially turned up more than 600 cases. Reporters handbuilt a database to track the overdoses and key details about them, including blood-mitragynine concentrations, contributing medical conditions and every substance flagged in a person’s system during toxicology testing.
A Times investigation found more than 580 fatal kratom-related overdoses in Florida.
