One in four US teens at some schools are abusing prescription stimulants such as Adderall, a Government-funded study suggests.

The School Crime Supplement (SCS) to the National Crime Victimization Survey collected data on bullying1 by asking students ages 12–18 if they had been bullied at school2 during the school year. Students were also asked about the types and frequencies of bullying they had been subjected to and where the bullying occurred.
