The motivation that drives addiction (severe substance use disorders) is best understood as primary, not derivative of other, commonly experienced motivations -- though addiction often begins with other motivations. The term, “sui generis,” emphasizes this. Addiction involves an intense focus on using, with a motivational salience to use frequently, and to engage in associated behavior, cognition, and conation -- to the point that it takes over the user’s life, superceding common sense, reasonable judgment, and acceptable behavior. Addiction is usually accompanied by physical dependence, but is not the same thing: that is, using to avoid withdrawal is not the same as using to gratify addictive craving. But physical dependence or other motivations may appear as “pseudo-addiction.” Addictive craving is not a psychological derivative of other motivations (though an addict will say otherwise). In its pathogenesis, occasional alcohol or drug use becomes routine. Then, regular use becomes a turning point for many, toward addiction.
