A survey was done by participants taking CBD for a mood disorder, most stated that they had anxiety, depression, or both. The most common types of anxiety were generalised anxiety disorder (50% of all participants taking CBD for anxiety), social anxiety (10%), and panic disorder (10%).

CBD has also shown antidepressant-like effects in several animal studies. These qualities are linked to CBD’s ability to act on the brain’s receptors for serotonin, a neurotransmitter that regulates mood and social behaviour.
