An initial step towards integrating these phenotypes is to define their conceptual properties. Alcohol-related aggression refers to aggressive acts that are associated with the perpetrator’s recent alcohol consumption. Drug-related aggression captures aggressive acts that are associated with the perpetrator’s recent consumption of illicit drugs (e.g., amphetamines, cocaine, marijuana, opioids). Conversely, non-substance-related aggression represents aggressive acts that are not associated with recent alcohol/drug consumption by the perpetrator of those aggressive acts. Yet what are the underlying relations among these three phenotypes?
