• Emergency department (ED) drug mentions<br />

data were provided by DAWN, OAS, SAMHSA,<br />

for 1994 through 2002. The 2000 ED data were<br />

unavailable for methamphetamine. Also presented<br />

in this paper are preliminary unweighted<br />

data from the DAWN Live! restricted-access<br />

online query system administered by OAS, beginning<br />

in 2003. The 2003–2004 data represent a<br />

redesign of DAWN, and the data are not comparable<br />

to those from 2002 and before. The redesigned<br />

system has 74 of the 88 eligible hospitals<br />

in the Chicago sample, with 76 EDs in the sample.<br />

(Some hospitals have more than one ED.)<br />

Datasets for the 2 years have similar completeness<br />

ratings, though the 2004 sample size is<br />

more than three times larger than the 2003 sample.<br />

This may be related to several reasons, including<br />

limitations associated with implementing<br />

a new system in 2003. The 2003–2004 data are<br />

incomplete (not all EDs reported each month)<br />

and unweighted; they cannot be used as estimates,<br />

nor can they be used for comparison with<br />

future data. Only weighted data released by<br />

SAMHSA can be used for trend analysis. All<br />

DAWN cases are reviewed for quality control;<br />

based on the review, cases may be corrected or<br />

deleted. Therefore, the data presented in this paper<br />

are subject to change. The 2003–2004 data<br />

were accessed from the DAWN Live! update on<br />

January 17, 2005, and represent drug reports.<br />

Drug reports exceed the number of visits, since a<br />

patient may report use of multiple drugs (up to<br />

six drugs plus alcohol). A full description of the<br />

DAWN system can be found on the DAWN Web<br />

site .<br />

• Treatment data for the State of Illinois for fiscal<br />

years (FYs) 1999–2003 (July 1–June 30)<br />

were provided by the Illinois Division of Alcoholism<br />

and Substance Abuse (DASA). National<br />

and State-specific treatment admissions data for<br />

1992–2002 were provided by the Treatment Episode<br />

Data Set (TEDS) maintained by SAMHSA.<br />

• Arrestee drug testing data were provided by the<br />

Arrestee Drug Abuse Monitoring (ADAM) program,<br />

National Institute of Justice (NIJ), and are<br />

described in the June 2004 Chicago CEWG report.<br />

• Incidence data on drug-related calls were provided<br />

by the Illinois Poison Center (IPC) in Chicago<br />

for Cook County for 2001 through 2003.<br />

The IPC answered more than 93,000 calls in<br />

2003 on household products, herbal products,<br />

medication overdoses, adverse reactions to<br />

medications, alcohol or drug misuse, occupa-<br />

tional accidents, chemical spills, and other poisonings.<br />

• Price and purity data were provided by the Drug<br />

Enforcement Administration (DEA), Domestic<br />

Monitor Program (DMP), for heroin for 1991–<br />

2003; the data are preliminary and subject to updating.<br />

Price and purity data on drug samples analyzed<br />

through November 2004 were provided by<br />

the Illinois State Police (ISP), Division of Forensic<br />

Science. The Illinois State Police and DEA<br />

analysis of methamphetamine lab seizures in Illinois<br />

between 2001 and 2003 reported to the Illinois<br />

Attorney General were reviewed. The Illinois<br />

Criminal Justice Information Authority (ICJIA)<br />

provided data on methamphetamine-related arrests.<br />

National and Illinois data on drug availability,<br />

demand, production, cultivation, and distribution<br />

were available from the National Drug Threat<br />

Assessment June 2004 and the Illinois Drug<br />

Threat Assessment May 2002 reports, National<br />

Drug Intelligence Center, U.S. Department of Justice.<br />

The Office of National Drug Control Policy<br />

(<strong>ON</strong>DCP) report on Profile of Drug Indicators,<br />

Chicago, Illinois, published in April 2004, as well<br />

as the National Drug Intelligence Center 2003 Illicit<br />

Drug Prices: July 2003–December 2003 report,<br />

were reviewed. Data from the National Forensic<br />

Laboratory Information System (NFLIS)<br />

for FY 2003 and FY 2004 were used to report differences<br />

between different drugs in the relative<br />

amounts submitted for testing in Illinois and Chicago.<br />

Ethnographic data on drug availability,<br />

prices, and purity are from observations and interviews<br />

conducted by the Community Outreach Intervention<br />

Projects (COIP), School of Public<br />

Health, University of Illinois at Chicago (UIC).<br />

• Survey data on student and household populations<br />

were derived from several sources. Student<br />

drug use data were provided by the national<br />

Monitoring the Future (MTF) Study, the Youth<br />

Risk Behavior Surveillance System (YRBSS)<br />

survey, and the Illinois Youth Survey and are<br />

described in the June 2004 Chicago CEWG report.<br />

National data on substance use and abuse<br />

were provided by SAMHSA’s 2002 National<br />

Survey on Drug Use and Health.<br />

• Most recent drug use estimates were derived<br />

from two currently ongoing studies of young<br />

heroin users in metropolitan Chicago conducted<br />

by COIP at UIC School of Public Health. The<br />

Family Process and Risk Reduction Study (Family<br />

Process), funded by the National Institute on<br />

Drug Abuse (NIDA), assesses a human immunodeficiency<br />

virus (HIV) prevention intervention<br />
