"• Arrestees are tested for the presence of 10 drugs. The proportion of arrestees testing positive for any of the 10 drugs ranged from 63 percent in Atlanta to 83 percent in Chicago and Sacramento. Arrestees testing positive for multiple drugs in their system ranged from 12 percent in Atlanta to 50 percent in Sacramento.
"• Marijuana remained the most commonly detected drug in urine testing, from 34 percent of ADAM II arrestees testing positive in Atlanta to 59 percent in Sacramento. Those who obtained marijuana in the prior 30 days reported little difficulty obtaining the drug, indicating an overall high availability of the drug in all sites.
"• In 2013, cocaine use, measured either as positive tests for cocaine metabolites or self-reported powder and/or crack use, continued a significant decline in all sites since 2000.
"• The self-reported use of crack in the prior 30 days declined significantly in all but New York (13 percent). In the other four sites the proportion of ADAM II arrestees in 2013 reporting using crack in the prior 30 days has decreased by half or more since 2007.
"• An increasing trend from 2000 to 2013 in the proportion of ADAM II arrestees testing positive for opiates (e.g., heroin, morphine, synthetic opiates) in their systems at the time of arrest was significant in all sites."
