Clinical Trial Summary

This laboratory study will investigate the impact of cannabis on pain, affect, and inflammation among patients with rheumatoid or psoriatic arthritis (n = 76). Two cannabis formulations varying in potency will be administered via vaporization across two experimental sessions using a counter-balanced, double-blind, crossover design.


Clinical Trial Description

This laboratory study will investigate the impact of cannabis on pain, affect, and inflammation among patients with rheumatoid or psoriatic arthritis (n = 76). Two cannabis formulations varying in potency will be administered via vaporization across two experimental sessions using a counter-balanced, double-blind, crossover design. Blood will be collected during each session (pre-vaporization, 10 minutes post-vaporization, 60 minutes post-vaporization). Self-reported pain and affect will be assessed at the same time points. The effect of cannabis on pain, affect, and inflammatory biomarkers will be assessed. The study will recruit 76 patients to obtain a final sample of 66 with complete data (15% attrition). This study will be the first to investigate the effect of cannabis on pain, affect, and markers of inflammation among patients with rheumatoid or psoriatic arthritis. This study has the potential to guide clinical decisions pertaining to use of cannabis to treat arthritis symptoms with more precise recommendations regarding cannabis formulation. ;
