About the Presentation: I will present findings from recently completed and ongoing research that uses smartphone-based assessments to collect data on real-time opioid and cannabis use and co-use among patients with chronic pain. I will cover both feasibility of data collection with this population and recent findings focusing on pain, perceived pain relief, opioid sparing, and other outcomes.
