2023 “New & Emerging” Findings for Kratom
- Severity: Among single-substance cases with known outcomes, 57.6% of kratom exposures produced a moderate/major/fatal effect (third-highest after tianeptine and phenibut).
- Hospitalization: 34.3% of kratom exposures resulted in hospital admission.
- Withdrawal: 4.76% of all kratom exposures were coded for withdrawal; of those seen in healthcare, 33.5% were admitted, and 13.5% of withdrawal calls originated from home.
- Bottom line: Despite unregulated retail availability, kratom shows high rates of clinically significant toxicity and frequent healthcare utilization—be prepared for both acute overdose and withdrawal management.
