Krüger et al. analyze the risk of long-term opioid use in a cohort of over 750,000 Swedish adults after a first prescription. They find that 8.1% continue to use opioids for longer than 3 months, with higher odds among individuals with psychiatric history and those initiating treatment in primary care.
