Discussion: By the definitions of modern psychiatry, which includes mental disorders, mental illness, addictions, autism, dementia, and more, you will find that half of the adult population is in this category!

Addictions are a widespread global phenomenon. The thought that Addiction is a brain disorder is unlikely, mainly due to its enormous scale. A brain disorder is a "malfunction" of natural mechanisms. There can be no fault in our body on such a scale! Therefore, the cause of Addiction is probably not a "brain disorder."
