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.

The Maricopa County Regional Trail System is a collection of trail corridors under the jurisdiction and control of many different agencies. Maricopa County has identified the Sun Circle and Maricopa Trails as its highest priorities for completion. At any time, should the opportunity arise, lower priority segments may be developed. The County’s priority designation may or may not coincide with the priorities of any agency whose trails have been identified as components of the regional system.
