The World Health organization (WHO) defines Heavy Episodic Drinking (or HED) “as consumption of 60 or more grams of pure alcohol (6+ standard drinks in most countries) on at least one occasion in the past 30 days” (2014:4). It is a complex and multifaceted drinking pattern that presents several challenges in terms of research, intervention and policy making. In this section some literature review will be presented that sustains the definition of the problem statement and the measures and methods chosen to address it.
