For much of the past 30 years, the default medical response to musculoskeletal pain — including the neck pain, back pain, and soft tissue injury that follows car accidents — was a prescription. Opioid pain medications, muscle relaxers, and anti-inflammatories were routinely issued at emergency rooms and primary care offices as first-line management for the pain that accident victims brought through their doors.

The consequences of that approach are now well-documented and widely acknowledged as a public health crisis. But the conversation that often gets lost in discussions of opioid addiction statistics is the simpler clinical question: does chiropractic care actually work better for these injuries? What does the research actually show?

The answer, across a growing body of rigorous peer-reviewed study, is yes — and by a substantial margin

The Landmark Study: Kazis et al., BMJ Open 2020

The most frequently cited recent study on this question was published in BMJ Open in 2020. The study examined data from more than 100,000 patients across the United States who had spine-related conditions — the category that encompasses the vast majority of car accident injuries.

The core comparison: patients who initiated their care with a chiropractor versus patients who initiated care with a primary care physician.

The findings:

•       Patients who began with chiropractic care used approximately 90% fewer opioid pain medications than those who began with physician-directed care

•       Chiropractic-first patients had significantly lower rates of advanced imaging orders

•       Chiropractic-first patients had fewer emergency department visits

•       Overall healthcare costs were substantially lower in the chiropractic-first group

The Veterans Study: Lisi et al., JGIM 2025

A 2025 study published in the Journal of General Internal Medicine examined outcomes in more than 128,000 military veterans with non-cancer musculoskeletal pain — one of the highest-risk populations for opioid use disorder in the United States. Veterans who received chiropractic care showed significantly lower rates of opioid medication use, lower rates of opioid-related adverse events, and reduced utilization of other pain management interventions.


Neck Pain Specifically: Bronft et al., Annals of Internal Medicine 2012

For car accident patients, neck pain is the most common presenting complaint. A randomized controlled trial published in Annals of Internal Medicine compared spinal manipulation, medication, and home exercise for acute neck pain. Results at 12 weeks: spinal manipulation produced a 57% reduction in pain, compared to 33% for medication and 33% for home exercise. At the 52-week follow-up, the advantage of spinal manipulation was maintained.


The Clinical Guidelines: Journal of Clinical Medicine 2024

A comprehensive meta-analysis published in the Journal of Clinical Medicine in 2024 reviewed 6,286 research articles on spinal manipulative therapy. The researchers found that 90 to 100 percent of the clinical practice guidelines examined recommend spinal manipulation as first-line treatment for musculoskeletal pain conditions. This is the mainstream evidence-based consensus — not a fringe perspective.

Why Opioids Are the Wrong Tool for These Injuries

Opioid pain medications address the symptom — pain — by suppressing the neurological signal. They do not address the underlying cause. Spinal misalignment remains misaligned. Disc herniation remains herniated. Ligament tear remains torn. The medication creates the feeling of improvement while the structural problem that generates the pain continues unaddressed.

Chiropractic care operates on the structural cause. Adjustments restore spinal alignment. Decompression reduces intradiscal pressure. Soft tissue therapy promotes healing in injured tissue. The result is genuine improvement in the underlying condition — not just suppression of the pain signal it generates.
