Though cannabinoids in marijuana are touted by salespeople and supplement marketing as therapies for almost anything, anecdotes are not evidence, and
the evidence from a meta-analysis of 83 studies (3,000 people) for six mental health conditions shows cannabinoids do not work. Not for depression, anxiety disorders, attention-deficit hyperactivity disorder (ADHD), Tourette syndrome, post-traumatic stress disorder(PTSD), or psychosis. And since there are known risks of cannabinoids they may be doing harm.
