Summary
This study is designed to track brain functional changes in individuals with i) chronic back pain + opioid use (CBP+O) and individuals with ii) chronic back pain + opioid misuse disorder (CBP+mOUD) following a brief drug delay and re-exposure manipulation. Re-exposure could be placebo, the participant's own opioid dose, or a dopaminergic treatment (DA+NSAID). The participants will be also evaluated for changes in cognition, emotion, and motor abilities with opioid delay and re-exposure to placebo, opioid, or DA+NSAID.
