CBD oil has received a lot of attention recently as the nonintoxicating cannabinoid that can potentially alleviate myriad symptoms and conditions. Of those, anxiety is at the top of the list. A 2015 study found that CBD reduced symptoms of anxiety in people with a diagnosed anxiety disorder. Brain scans of participants revealed changes in blood flow to the regions of the brain linked to feelings of anxiety. In this study, CBD not only made participants feel better but also changed the way their brains responded to anxiety. Just like with any medication, speak with a professional to see if the use of cannabis is right for you.
