Study: Kratom Detected in Fatal Overdoses at 4x Higher Rates in States with No Policy vs. Schedule I States

Why it matters

This is the first study to use CDC State Unintentional Drug Overdose Reporting System (SUDORS) data to examine whether state-level kratom laws are associated with fatal overdose rates, providing policymakers empirical evidence about which regulatory approaches correlate with reduced kratom-linked deaths.

The big picture

States have taken widely divergent approaches to kratom — from Schedule I prohibition (Alabama, Arkansas, Indiana) to consumer protection regulation under the Kratom Consumer Protection Act to no state policy at all. The DEA's proposed federal scheduling of 7-OH adds urgency to understanding which frameworks actually reduce harm. This retrospective ecological analysis is among the first to link specific policy environments to kratom detection data from overdose death records.

Key findings

• Analysis covered 45 U.S. jurisdictions using 2020–2024 SUDORS overdose death data
• Kratom detection rates in fatal overdoses were 3.27x higher in regulated states vs. Schedule I states (IRR 3.27, 95% CI 1.78–6.02)
• Kratom detection rates were 4.19x higher in states with no statewide policy vs. Schedule I states (IRR 4.19, 95% CI 2.94–5.98)
• Opioid-stimulant co-involvement was a significant covariate in overdose deaths involving kratom
• Results were consistent across multiple statistical models including quasi-Poisson fixed-effects
• Authors note that these findings reflect correlation, not causation; unmeasured confounders may affect results

What they say

The authors noted that "state policy context may influence kratom availability and detection" in fatal overdoses, and called for "ongoing monitoring and policy evaluation" as the regulatory landscape continues to shift — particularly given the impending federal action on 7-OH.

Bottom line

**States with strict kratom prohibition recorded kratom-detected overdose deaths at roughly one-quarter the rate of states with no policy — the first epidemiological evidence linking state kratom regulatory status to fatal outcomes.**
