Chronic for chronic pain? An investigation into medical marijuana efficacy when accounting for duration of chronic pain

This faculty research project investigates the efficacy of medical marijuana for chronic pain while explicitly accounting for the duration of patients' chronic pain. PCOM’s multi-study medical cannabis research program, seeks to gather and share data and insights on medicinal cannabis impacts across domains including quality of life, cognition, opioid management, and chronic pain.

This investigation focuses on an unresolved but clinically important question: does the length of time a patient has experienced chronic pain modify the therapeutic effects of cannabis-based treatments? Prior findings motivate a more nuanced, temporally informed analysis: whereas earlier work demonstrates that some patients experience significant benefits within months of treatment, this study interrogates whether treatment timing relative to pain chronicity alters outcomes, risk–benefit profiles or optimal dosing and delivery strategies.

Methodologically, the project is situated within PCOM’s multi-study approach to medicinal cannabis, which encompasses clinical, behavioral and translational research. It intends to examine patient-reported outcomes, functional measures, and potential changes in concurrent medication use (including opioid management), with careful attention to baseline characteristics such as pain duration.

By explicitly addressing duration of chronic pain as a modifier of treatment effect, this work aims to refine patient selection criteria, improve individualized treatment planning and clarify whether early versus long-standing chronic pain responds differently to cannabis-based interventions. The research underscores PCOM’s broader goal of producing evidence that guides safe, effective and equitable use of medicinal cannabis across a range of indications, while contributing to state-mandated research efforts that advance clinical understanding of this class of therapies. Ultimately, this investigation seeks to translate PCOM’s institutional research capacity into actionable knowledge for clinicians, educators and patients managing chronic pain.
