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.

Maricopa County's Parks and Recreation Department now features one of the nation's largest county park systems, with 10 regional parks totaling more than 120,000 acres. In an effort to manage the future needs of residents and the growth of the county the Department decided to update the previous Master Plan for the Park System which was completed over 40 years ago. The Strategic System Master Plan evaluates all aspects of the Department’s management efforts and seeks strong community input into the elements and expectations they have for the system today and in the future.
