Based on data collected in 2011, a new study has found an association between both a higher per-capita supply of chiropractors and Medicare spending on chiropractic care and lower opioid prescription use among younger, disabled Medicare beneficiaries. Opioids are a type of narcotic pain medication that can have serious side effects and can lead to abuse and dependence. The finding suggests that chiropractic care may help reduce the need for this potentially dangerous class of medication. Journal of Manipulative Physiological Therapeutics, March 2016
