Are "physiological" and "psychological" addiction really different? well, no! ... um, er, yes?
The distinction often made between psychological and physiological addiction is a form of mind-body dualism. Therefore, it is a false distinction. However, this does not imply that behavioral and autonomic symptoms of addiction have the same brain substrates. In fact, they likely do not, although there is some overlap.
