Disease generally implies the damage or malfunction of a system of the body. Whereas addiction is a malfunction of behavior. My comment likely didn’t translate my thoughts clearly enough. I would not argue against “mental disease”. The distinction between physical and mental disease is important (because treatment is so different) and under common definition physical disease is implied. That was the miscommunication in my and many other comments in this thread.
