| Mohammed SYM et al. | 2024 | Systematic review | Pain management nursing | Systematic review found CBD may reduce chronic pain by 42-66%, though evidence is limited by heterogeneous study designs and small sample sizes |
| Villanueva MRB et al. | 2022 | Systematic review | Cureus | Systematic review of 12 publications found CBD shows promise for chronic pain management with a favorable safety profile, though more rigorous RCTs are needed |
| Shannon S et al. | 2019 | Study | The Permanente Journal | In 72 adults with anxiety and poor sleep, CBD (25-175mg/day) reduced anxiety scores in 79.2% and improved sleep in 66.7% within the first month |
| Vuckovic S et al. | 2018 | Study | Frontiers in Pharmacology | Review confirms cannabinoids including CBD show significant analgesic effects for chronic pain through multiple mechanisms, with CBD offering anti-inflammatory benefits without psychoactive side effects |
| Blessing EM et al. | 2016 | Study | Neurotherapeutics | Preclinical and human studies strongly support CBD as a treatment for anxiety disorders, with acute doses of 300-600mg reducing experimentally induced anxiety |
Study Details
Psychiatry research
View Summary
This systematic review and meta-analysis evaluated the therapeutic potential of CBD for anxiety disorders. Eight articles with 316 participants were included. The meta-analysis revealed a substantial significant impact of CBD on anxiety with a considerable effect size (Hedges' g = -0.92, 95% CI -1.80 to -0.04).
Pain management nursing
View Summary
This systematic review synthesized evidence on CBD effectiveness for chronic pain management. From 1,516 identified articles, 15 studies were included. The majority indicated pain reduction ranging from 42-66% with CBD alone and CBD combined with THC.
Cureus
View Summary
This systematic review evaluated the efficacy, safety, and regulatory landscape of CBD for chronic pain. Five databases were searched, applying inclusion criteria for adults with pain lasting over 3 months. Twelve publications were eligible, suggesting CBD may be effective for chronic pain with acceptable safety.
The Permanente Journal
View Summary
This large retrospective case series from a psychiatric clinic examined CBD as an adjunct to standard treatment for anxiety and sleep complaints. Results showed rapid improvements in both anxiety and sleep scores with good tolerability, providing real-world evidence for CBD's therapeutic potential.
Frontiers in Pharmacology
View Summary
This comprehensive review examined the mechanisms and clinical evidence for cannabinoids in chronic pain management. The authors concluded that cannabinoids, including non-psychoactive CBD, represent a promising approach for treating various chronic pain conditions through their effects on the endocannabinoid system and inflammatory pathways.
Neurotherapeutics
View Summary
This comprehensive review examined evidence from preclinical, human experimental, clinical, and epidemiological studies on CBD for anxiety. The authors found consistent anxiolytic effects across multiple anxiety paradigms and disorders, supporting CBD as a promising treatment option.
Evidence Assessment
This intervention has moderate evidence from some randomized trials and consistent observational data, though more research would strengthen conclusions.
