Is it true that Microdosing psychedelics improves attention deficit hyperactivity disorder symptoms in adults?

Partly. One naturalistic prospective study reports lower ADHD symptoms after four weeks of microdosing psychedelics in adults with severe ADHD symptoms, and a systematic review notes some studies suggest cognitive and mental-health benefits, though it flags the evidence as weak and biased. A general microdosing reference states microdosing has not improved attention and remains unproven.
