Alcohol dependence is characterised by a cluster of cognitive, behavioural and physiological symptoms, with an affected individual continuing to drink despite significant alcohol-induced impairment or distress. Since alcohol affects most human organs, its abuse is associated with a wide range of physical, mental and social harm. According to the World Health Organisation,1 alcohol abuse constitutes a serious public health problem worldwide, accounting for 4% of the global burden, a burden comparable to the death and disability attributable to tobacco and hypertension.1,2
