Every age group has been affected by the relative ease of hydrocodone availability and the perceived safety of these products by medical prescribers. Sometimes viewed as a “white collar” addiction, hydrocodone abuse has increased among all ethnic and economic groups. Of particular concern is the prevalence of illicit use of hydrocodone among school age children. In 2006, the Monitoring the Future Survey (commonly referred to as the high school survey) reported that 3%, 7% and 9.7% of 8 th, 10 th, and 12 th graders, respectively, reported non-medical use of Vicodin ® in the previous year.
