Abstract
Drinking alcohol-containing beverages is a common habit in Western countries. In most Western societies, at least 90% of people consume alcohol at some time during their lives, and 30% or more of drinkers develop alcohol-related life problems.1 Severe alcohol-related life impairment, alcohol dependence, is observed at some time during their lives in ∼10% of men and 3–5% of women, with an additional 5–10% of each sex developing persistent but less intense problems that are diagnosed as abuse.1
