Practical considerations for testing the effects of cannabidiol on human anxiety.

Empirical evidence continues to accumulate suggesting cannabidiol (CBD) may have potential as an anxiolytic. Yet, research in the area is insufficient to support strong inferences. Accordingly, there is a need for additional empirical investigation. Research on the effects of CBD and anxiety requires a working knowledge of both. Understanding of contemporary CBD and anxiety research methods is critical to safely and convincingly test predictions regarding potential anxiolytic effects of CBD. The current paper outlines major design, methods, and safety considerations pertinent both to CBD administration and measuring effects on anxiety outcomes in order to facilitate needed research in this domain.
