Chance an Overdose Death Involved Xylazine (2023)

NCHS reported 6,096 drug overdose deaths involving Xylazine in 2023, ranking it number 4 among the drugs most frequently mentioned in overdose death records. That equals 5.7% of the 106,352 U.S. drug overdose deaths in the report's 2023 table.

This is a conditional probability, not the probability that a random person dies from Xylazine. The denominator is drug overdose deaths, and the numerator is overdose deaths in which Xylazine was identified from death-certificate literal text. NCHS emphasizes that overdose deaths may involve multiple drugs, so these drug-specific percentages are not mutually exclusive and should not be added together.

The decision value is practical risk interpretation. Drug-specific overdose data helps separate the overall overdose crisis into substances and combinations that call for different responses: naloxone access, fentanyl test strips where legal and appropriate, medication-assisted treatment, careful prescribing, avoiding solitary use, safer storage, and faster emergency response. For Xylazine, the report notes: Xylazine emerged into the top 15 in 2021 and rose to fourth by 2023, with fentanyl co-involvement reported in nearly all xylazine-involved deaths.

There are important limitations. The method relies on what medical certifiers wrote on death certificates, and NCHS says the reported numbers should be considered minimum counts because additional deaths may have involved the drug without it being captured in the literal text. Reporting improved over time, so trend comparisons require caution.
