ABSTRACT
Background
Generalized anxiety disorder (GAD) is a common mental health condition. The endocannabinoid system has become a focus for new therapies, increasing interest in cannabis-based medicinal products (CBMPs). This study uses data from the UK Medical Cannabis Registry (UKMCR) to investigate real-world outcomes and safety of different CBMP formulations in GAD patients.
Methods
This study analyzed patient-reported outcomes from 302 GAD patients prescribed CBMPs (oil-based, dried flower, or a combination). Anxiety (GAD-7), sleep quality (SQS), and quality of life (EQ-5D-5 L) were assessed at 1, 3, 6, and 12 months. Adverse events were recorded.
Results
All CBMP formulations were associated with improvements in anxiety, sleep, and quality of life over 12 months (p < 0.050). At 12 months, there were no significant differences in outcomes between formulations (p > 0.050). The majority of reported adverse events (n = 707) were mild (n = 343) or moderate (n = 285) in severity, with no life-threatening events observed.
Conclusion
This study provides real-world evidence supporting the potential of CBMPs for improving GAD symptoms. Patients prescribed both oil-based and dried flower formulations have similar outcomes over 12 months. Further research is needed to determine the optimal CBMP formulation and long-term effects.
