Mar. 16, 2026 – Researchers concluded there was “very little evidence for its efficacy” in treating anxiety, anorexia nervosa, psychotic disorders, post-traumatic stress disorder or opioid use disorder. “There were no significant effects on outcomes associated with anxiety, anorexia nervosa, psychotic disorders, post-traumatic stress disorder and opioid use disorders.”There was too little evidence as to whether cannabinoids helped to tackle attention deficit hyperactivity disorder, bipolar disorder, obsessive compulsive disorder and tobacco use disorder, and none at all for whether it was an effective treatment for depression.
