Individuals vary in their response to the quantity of alcohol needed to become intoxicated [26] and metabolic rate of processing alcohol [27]. There are different behavioural consequences of higher blood alcohol levels and binge drinking (episodic heavy drinking), particularly in relation to increased aggression [28,29]. Furthermore, aggression increases with subjective perception of intoxication [28]. Indeed, there are specific risks involved in binge drinking and drunkenness that are separate from mean daily quantity of alcohol consumed [26,30]. It is therefore important, in addition to quantity of alcohol consumed, to look at a range of outcomes relating to problem use.
