Chiropractic Care Cuts Opioid Starts in Veterans by Nearly a Quarter

The Opioid Challenge Inside the VA

“Even a single new opioid prescription can reset the course of a veteran’s life.”

Veterans shoulder disproportionate burdens of chronic pain, mental‑health conditions, and past substance‑use disorders. Those factors make any initial exposure to opioids especially risky. For more than a decade, the Veterans Health Administration (VHA) has promoted non‑pharmacologic options, but evidence clarifying which services actually lower opioid use has remained scarce.

What the Study Asked

Investigators analyzed five years of VA electronic health‑record data, following 128,377 opioid‑naïve veterans who visited primary care for a new episode of low back pain between 2015 and 2020. They compared veterans who later received at least two on‑station chiropractic visits with those who received none. After matching patients on age, pain severity, comorbidities, and use of other non‑drug therapies, 25,908 veterans remained in the analysis. The outcome was straightforward: who filled an opioid prescription during the following year.

Key Findings

Within twelve months, 16.8 percent of veterans who never saw a chiropractor filled an opioid prescription, compared with only 13.0 percent of those who did. That 3.8‑percentage‑point absolute difference translates to a relative risk reduction of roughly 23 percent (hazard ratio 0.77, 95 % confidence interval 0.71–0.83). In practical terms, providing chiropractic care to twenty‑seven opioid‑naïve veterans prevents one of them from starting opioids.

Why a 3.8‑Point Drop Matters

Three‑point‑eight percentage points may seem modest until it is multiplied by the VA’s huge patient base. The VHA manages roughly one million low‑back‑pain visits each year. If only one in ten of those veterans obtained chiropractic care at the effectiveness shown here, nearly 3,800 opioid starts could be avoided annually. Each avoided start removes a potential gateway to prolonged use, dependence, or overdose in a population already at elevated risk.

“One fewer opioid start for every twenty‑seven veterans is a tangible win against a crisis still claiming more than 80,000 American lives a year.”

Implications for Integrative Pain Care

The findings dovetail with national guidelines that call for non‑drug therapies as first‑line treatment for low back pain. They also validate the VA’s ongoing investment in on‑station chiropractic clinics. For primary‑care teams, the message is pragmatic: early referral to chiropractic services offers a measurable, low‑risk method to reduce opioid exposure without compromising pain management.

Limitations and Future Questions

Because the study was observational, unknown factors—such as a veteran’s personal preference for drug‑free care—could still influence results. Chiropractors outside VA facilities, paid through community‑care programs, were not counted, so some exposure may have been missed. Finally, the analysis treated “two or more” visits as a single dose; research is still needed to determine the ideal number and timing of chiropractic visits to maximize opioid‑sparing benefits.

Takeaway for Clinicians and Policymakers

“Chiropractic care is not a silver bullet, but it is a safe, scalable lever that measurably reduces opioid starts in a high‑risk group.”

When a simple, low‑cost intervention can prevent thousands of veterans from ever filling their first opioid prescription—and do so with minimal downside—the case for expanding access becomes compelling. Integrating chiropractic services more fully into routine low‑back‑pain care should be central to the VA’s, and the nation’s, continuing effort to turn the opioid tide.
