Globally, harmful alcohol use is a
major modifiable contributor to the
burden of disease.1 The typical age of initiation of alcohol use is around mid-adolescence and for a significant minority of adolescents their alcohol use will result in substantial harms, the most costly of which is alcohol use disorder (AUD).2 Defined as a cluster of symptoms indicating continued alcohol use despite significant problems, AUD is common and imposes a significant
burden on the individual, their family and the wider
society.
