The document summarizes findings from the 2010 Scottish Schools Adolescent Lifestyle and Substance Use Survey (SALSUS) regarding drinking by Scottish school pupils. It finds that nearly 60% of 13-year-olds have never had an alcoholic drink, compared to only 23% of 15-year-olds. It also reports that 86% of 13-year-olds and 66% of 15-year-olds have not drunk alcohol in the last week. The data further examines factors like deprivation, family structure, attitudes, and perceptions of support that relate to drinking behaviors among Scottish youth.
