Medical cannabis for pain management in patients undergoing chronic hemodialysis: randomized, double-blind, cross-over, feasibility study

Abstract Background: Chronic pain is prevalent but difficult to treat in patients undergoing hemodialysis (HD). Effective and safe analgesics are limited in this patient population. Our aim in this feasibility study was to evaluate the safety of sublingual oil based medical cannabis for pain management in patients undergoing HD. Methods: In a prospective randomized, double-blind, cross-over design, patients undergoing HD with chronic pain were assigned to one of three arms: BOL-DP-o-04-WPE whole-plant extract (WPE), BOL-DP-o-04 cannabinoid extraction (API) or placebo.
