Addiction, competence and coercion

In what sense is a person addicted to drugs or alcohol incompetent, and so a legitimate object of coercive treatment? The standard tests for competence do not pick out the capacity that is lost in addiction: the capacity to properly regulate consumption. This paper is an attempt to sketch a justificatory framework for understanding the conditions under which addicted persons may be treated against their will. These conditions rarely obtain, for they apply only when addiction is extremely severe and great harm threatens. It will be argued also that to widen the measures currently in place in some jurisdictions, though philosophically well-motivated, would require very strong evidence of a set of conditions disposing a person to an addictive future. It is doubtful that any such currently available evidence is strong enough to justify coercive treatment. Nevertheless, coercive treatment of addiction is already a reality, with the potential for more, and so some discussion will be presented regarding the extraordinary safeguards necessary to prevent misapplication of such treatment policies.
