Official title

Effects of Cannabidiol on Responses to Emotional Stimuli

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this research is to examine the effect of cannabidiol (CBD), a cannabinoid compound found in marijuana, on responses to emotional stimuli. Both preclinical and clinical studies indicate that CBD may act to reduce anxiety without excessive sedative side-effects. Thus the investigators hypothesize that CBD may reduce responses specifically to negative emotional and social stimuli, including pictures and emotional faces, without altering responses to positive stimuli. To examine this, the investigators will administer placebo, 300mg, 600mg, and 900mg CBD to healthy normal adults in a double-blind within-subjects study. The investigators will measure subjective and subtle physical responses to positive and negative stimuli using measures that have been characterized with classic anxiety-reducing drugs and drugs of abuse. Further, the investigators will examine whether CBD-induced changes in these measures of emotional response relate to changes in actual behavior in a controlled social interaction. These results will allow the investigators to examine the potential usefulness of CBD as an anxiety-reducing drug, and suggest mechanisms by which CBD may reduce anxiety.
