Young adults are at the highest risk for alcohol-related harm; so what do they know about responsible drinking practices? This study compared the knowledge of two groups of Australian young adults: apprentices and university students. The findings revealed that both groups have relatively low levels of knowledge regarding responsible drinking practices in three areas: the identification of standard drinks, the minimum number of standard drinks required to reach the legal blood alcohol concentration (BAC) driving limit, and actions effective in lowering BAC. The results reveal that these groups of young people need increased alcohol awareness, particularly in relation to responsible drinking practices.
