title: Psychoactive drug use: Expand the scope of outcome assessment.
abstract: The "hijacking" and "drug instrumentalization" models of psychoactive drug use predict opposite outcomes in terms of adaptive behavior and fitness benefits. Which is the range of applicability of each model? To answer this question, we need more data than those reported by studies focusing on medical, psychiatric, and legal problems in addicted users. An evolutionary analysis requires a much wider focus.
