That’s a model of addiction as a “habit” with a loss of self-control. But the other definition of addiction is really more like “continued use of the substance is required to eliminate a syndrome which only occurs when use of the substance is reduced or discontinued.” I think the latter model is more useful because there are tons of medications out there where responsibly using them leads to addiction. Even SSRIs could be addictive under that definition.
