Does CBD (Cannabidiol oil) help with anxiety?

According to a recent review assessing the potential therapeutic actions of CBD in humans (https://www.ncbi.nlm.nih.gov/pubmed/30730563) the beneficial effect of an acute dose of CBD before anxiety-provoking events is likely but not yet proven. More controlled clinical studies are needed to understand whether CBD does have anxiolytic properties. There are issues related with doses which could explain lack of consistency across different studies, and which are further complicated by the poor quality of non-FDA-approved products available in the market (which often contain less CBD than labeled) (see: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5818782/)

On Clinicaltrials.gov there is a randomized, double-blind, placebo-controlled clinical study comparing the efficacy of CBD Oil capsules (different doses) for the treatment of the following anxiety disorders: Generalized Anxiety Disorder (GAD), Social Anxiety Disorder (SAD), Panic Disorder (PD), or agoraphobia. The outcomes of this research will help to enhance our current understanding of the effects of CBD on anxiety disorders. https://clinicaltrials.gov/ct2/show/NCT03549819
