There were no significant effects on outcomes associated with anxiety, anorexia nervosa, psychotic disorders, post-traumatic stress disorder, and opioid use disorder. There were insufficient data to meta-analyse studies of ADHD, bipolar disorder, obsessive-compulsive disorder, and tobacco use disorder. There was an absence of RCT evidence for the treatment of depression.

This study, or meta-study, as it's just coalescing existing ones. Found none showed significant benefits, although it sounds like it is more just a lack of evidence rather than evidence of it not helping. Especially with depression. Which makes the headline disingenuous. "No evidence that it treats these" but also we don't have enough evidence to actually say.
