National and County-Level Trends in Opioid Dispensing

5 min read

A new JAMA research letter tracks pharmacy opioid dispensing across the United States from 2019 through 2025. Its county-level view matters—but understanding what the numbers can and cannot say matters just as much.

Horizontal landscape editorial header image about national and county-level opioid dispensing trends in the United States: a clean, restrained visual combining a softly lit pharmacy counter with a subtle, abstract U.S. county map in the background, emphasizing public-health data and careful clinical judgment, no identifiable medications or readable labels, no text or logos, professional clean composition, photorealistic.

What the new study measures—and what it doesn’t

On October 21, 2026, JAMA published a research letter by Lyna Z. Schieber, Charles M. Adjei, and Gery P. Guy Jr. The CDC-affiliated authors describe a cross-sectional analysis of U.S. pharmacy data examining opioid dispensing patterns from 2019 through 2025, at both national and county levels. That makes the work a recent map of dispensing activity, not an experiment testing a particular policy or treatment.

A key reporting limit is worth stating plainly: the accessible JAMA abstract and publication notice identify the study and its years, but do not show its results tables, specific rates, or county examples. Without those figures, claims about how much dispensing changed, which counties rose or fell, or where rates were highest would be guesswork. The sound conclusion is narrower: this study provides a framework and data snapshot for tracking national and local dispensing, while the precise findings need to be checked against the full letter.
