Sponsor's own description

This study follows up patients who receive standard treatment for prescription narcotic drug use disorder, including opioids, benzodiazepines, and benzodiazepine-like drugs (z-drugs), at a specialized addiction service. The overall goal is to evaluate the proportion of patients who reduce or cease using prescription narcotics and the factors associated with treatment outcomes. No new treatments will be tested. Instead, the results will be used as the basis for a future randomized controlled trial to optimize treatment for narcotic drug use disorder.
