A 2016 case study checked out whether cannabidiol could decrease symptoms of post-traumatic stress disorder (PTSD) as well as anxiety-provoked rest problem in a kid with a background of trauma. Scientists discovered that cannabidiol minimized the kid's anxiety and assisted her rest. A 2011 study also found that cannabidiol can lower social anxiety. For that research study, researchers looked particularly at cannabidiol to treat stress and anxiety associated with public speaking.
