Outside of those four states, consumers must put their trust in the manufacturer. Sometimes that’s warranted, and sometimes it’s not. In 2016 and 2016, the FDA ran tests on several CBD products and found that many of the products had far less CBD than advertised, and in some cases none at all.

CBD products are not approved by the FDA for the prevention, mitigation, or treatment of any disease or condition.)
REM Behavior Disorder: REM behavior disorder (RBD) is a parasomnia disorder characterized by shouting, becoming physically agitated, or otherwise acting out during sleep. For many, RBD is a symptom of a larger, more serious condition or disorder, such as Alzheimer’s disease or PTSD. CBD oil minimizes the symptoms of RBD, and also alleviates the anxiety and painful symptoms that often accompany disorders that lead to RBD.
