PubMed: Efficacy, Safety, and Regulation of Cannabidiol on Chronic Pain: A Systematic Review

Cureus. 2022 Jul 16;14(7):e26913. doi: 10.7759/cureus.26913. eCollection 2022 Jul.


We conducted a systematic review to determine the efficacy and safety of cannabidiol (CBD) for chronic pain. The systematic review is according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020 checklist. Five databases (PubMed, PubMed Central, Medline, Cochrane Library, and ScienceDirect) were searched using cannabidiol, CBD, hemp, and chronic pain. Inclusion criteria used were studies on adult populations >18 years old; pain symptoms >three months duration; all available preparations of CBD; human studies only; publication in English in the past five years. A total of 2298 articles were found. Inclusion criteria were applied, and quality assessments were done, resulting in 12 publications eligible for the review. CBD and tetrahydrocannabinol (THC), both from Cannabis plants with almost identical chemical structures, attach to the CB receptor, eliciting different effects like the psychoactivity seen on THC but less or none in CBD. Regulations of CBD worldwide differ from each other due to the insufficiency of solid evidence to establish its benefit versus the risks. However, a few studies are showing the benefits of CBD not only for chronic pain but also for sleep improvement and quality of life. In conclusion, CBD is an excellent alternative to an opioid in chronic pain because CBD is non-intoxicating in its pure form. More clinical trials should be done to prove CBD’s significance clinically and statistically.
