What this trial studies

This research investigates the impact of cannabidiol (CBD) on chronic pain symptoms in veterans. Participants will be randomly assigned to receive either CBD or a placebo, allowing for a comparison of pain relief between the two groups. The study aims to determine if CBD can significantly improve pain management for veterans suffering from chronic pain. Participants must be enrolled in a pain registry and agree to specific guidelines regarding cannabis use during the study.
