Topical CBD for Musculoskeletal Pain

Rationale: CBD is commonly being used as an over-the-counter treatment for musculoskeletal pain; however, no clinical trial has been performed to establish efficacy of CBD in humans for musculoskeletal pain. Hypothesis: CBD is more effective than placebo for relieving pain and improving patient-reported outcomes for musculoskeletal pain. Study Design: The study design with be a double-blind, randomized controlled trial with crossover. Treatment will be blinded to the subjects and investigators. Patients will be randomly assigned 2 weeks of the CBD or control and then crossover to the other condition for 2 additional weeks. Patients will apply the CBD or control cream to the affected area twice daily (approximately every 12 hours) for 1 hour. Subjects will be advised to observe for physiologic changes, skin changes, or other adverse effects.
