Similarly, the modern medical view of addiction is basically something like, "continued use in the face of adverse consequences." Laypeople really hate this definition, preferring to think of addiction as primarily a physio-chemical phenomenon, but the American Psychiatric Association has to say:

"Substance use disorder (SUD) is complex a condition in which there is uncontrolled use of a substance despite harmful consequence."

Most organizations that deal with addiction now operate using a similar definition.
