What this trial studies

This observational study aims to understand how Black and White patients with solid tumor cancer utilize cannabis, opioids, and tobacco. Researchers will employ a momentary ecological assessment via a smartphone app to gather real-time data on patient-reported pain and symptom management over a 12-month period. The study will enroll 200 participants, split evenly between cannabis users and non-users, to assess the longitudinal impact of cannabis on opioid use and pain management. Data will be collected remotely to minimize participant burden and enhance engagement.

Who should consider this trial

Good fit: Ideal candidates are Black or White adults aged 21 and older with solid tumor cancer diagnosed within the last three years who experience pain and have been prescribed opioids.

Not a fit: Patients with lymphoma, leukemia, melanoma, or those using CBD only or synthetic cannabis in the past three months may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into effective pain management strategies for cancer patients, particularly in underrepresented populations.

How similar studies have performed: While studies on cannabis use in cancer patients exist, this specific approach using momentary ecological assessment is relatively novel and has not been extensively tested.
