During 2008, 2,105 adult arrestees participated in the AARIN study. Participants completed the survey instrument and provided a valid urine specimen for testing. In addition to the core AARIN instrument, a supplemental set of question was asked of the arrestees. This Market and Use Addendum consisted of a series of questions related to the arrestees’ acquisition of drugs and specific drug market behaviors.

This special topic report examines the prevalence and characteristics of co-occurring substance abuse and mental health problems among juvenile detainees in Maricopa County. The findings come from the Co-occurring Disorder Addendum used during 2007. The findings reveal that almost 30 percent of juvenile detainees were at risk for a co-occurring disorder, and face significantly greater difficulties across a number of critical factors, including incarceration, homelessness, and victimization.
