Crack, Powder Cocaine, and Heroin: Drug Purchase and Use Patterns in Six Cities in the United States, 1995-1996 (ICPSR 2564)
Released/updated on: 2012-08-22
Geographic coverage: New York City, Oregon, District of Columbia, San Diego, San Antonio, United States, Chicago, Illinois, Texas, Portland (Oregon), California, New York (state)
Time period: 1995-01-01--1996-01-01
This study was designed to address the practical and policy implications of various drug market participation patterns. In 1995, the Office of National Drug Control Policy (ONDCP) and the National Institute of Justice (NIJ) collaborated on a project called the Procurement Study. This study was executed as an addendum to NIJ's Drug Use Forecasting (DUF) program (DRUG USE FORECASTING IN 24 CITIES IN THE UNITED STATES, 1987-1997 [ICPSR 9477]) with the goal of extending previous research in which heroin users were interviewed on various aspects of drug market activity. The present study sought to explore additional features of drug market participation and use, both within and across drug types and cities, and included two additional drugs -- powder cocaine and crack cocaine. Data were collected from recently arrested users of powder cocaine, crack cocaine, and heroin in six DUF cities (Chicago, New York, Portland, San Diego, San Antonio, and Washington, DC). Each of the three files in this collection, Crack Data (Part 1), Heroin Data (Part 2), and Powder Cocaine Data (Part 3), is comprised of data from a procurement interview, urine test variables, and a DUF interview. During the procurement interview, information was collected on purchase and use patterns for specific drugs. Variables from the procurement interview include the respondent's method of using the drug, the term used to refer to the drug, whether the respondent bought the drug in the neighborhood, the number of different dealers the respondent bought the drug from, how the respondent made the connection with the dealer (i.e., street, house, phone, beeper, business/store, or friends), their main drug source, whether the respondent went to someone else if the source was not available, how the respondent coped with not being able to find drugs to buy, whether the respondent got the drug for free, the means by which the respondent obtained money, the quantity and packaging of the drug, and the number of minutes spent searching for, traveling to, and waiting for their last purchase. Urine tests screened for the presence of ten drugs, including marijuana, opiates, cocaine, PCP, methadone, benzodiazepines (Valium), methaqualone, propoxyphene (Darvon), barbiturates, and amphetamines (positive test results for amphetamines were confirmed by gas chromatography). Data from the DUF interview provide detailed information about each arrestee's self-reported use of 15 drugs. For each drug type, arrestees were asked whether they had ever used the drug, the age at which they first used the drug, whether they had used the drug within the past three days, how many days they had used the drug within the past month, whether they had ever needed or felt dependent on the drug, and whether they were dependent on the drug at the time of the interview. Data from the DUF interview instrument also included alcohol/drug treatment history, information about whether arrestees had ever injected drugs, and whether they were influenced by drugs when the crime that they were charged with was committed. The data also include information about whether the arrestee had been to an emergency room for drug-related incidents and whether he or she had had prior arrests in the past 12 months. Demographic data include the age, race, sex, educational attainment, marital status, employment status, and living circumstances of each respondent.

Dynamics of Retail Methamphetamine Markets in New York City, 2007-2009 (ICPSR 29821)
Released/updated on: 2014-01-06
Geographic coverage: New York City, United States, New York (state)
Time period: 2007-01-01--2009-12-31
The study was conducted to provide information about markets for, distribution of, and use of methamphetamine in New York City, both inside and outside of the MSM (men who have sex with men)/gay community. The study used Respondent Driven Sampling to recruit 132 methamphetamine market participants. Each respondent participated in a one to two hour structured interview combining both qualitative and quantitative responses. Each respondent was invited to recruit three additional eligible participants. Data collected included demographics, social network data, the respondent's market participation in obtaining and providing methamphetamine, consumption of methamphetamine, and experience with the criminal justice system and crime associated with participation in methamphetamine markets.

Estimating the Elasticities of Demand for Cocaine and Heroin with Data from 21 Cities from the Drug Use Forecasting (DUF) Program, 1987-1991 (ICPSR 6567)
Released/updated on: 2006-03-30
Geographic coverage: United States
Time period: 1987-01-01--1991-01-01
The objective of this research was to estimate the elasticity of the demand for cocaine and heroin with respect to the price. Price elasticity is the percentage of change in the dependent quantity corresponding to a one-percent change in price. The project involved the development of an econometric model to determine price elasticity, given that national- and city-level data on the consumption of cocaine and heroin are insufficient or nonexistent. The researchers circumvented this lack of data by partitioning the desired elasticity into the product of two elasticities, involving a measurable intermediate quantity whose relationship to the quantity of consumption could be modeled and estimated by measurable techniques. The intermediate quantity used for this project was the fraction of arrestees testing positive for cocaine or heroin as measured by the Drug Use Forecasting (DUF) System. From the Drug Enforcement Administration's (DEA's) System to Retrieve Information from Drug Evidence (STRIDE) data, expected purity was computed by regressing on log quantity and dummy variables for location and quarter. Price series were produced by finding the median standardized price per expected pure gram for each location and quarter. Variables for Part 1, National Data, include year, quarter, standardized prices for a gram of cocaine and a gram of heroin, and expected purity of cocaine and heroin. The Cities Data, Part 2, cover city, year, quarter, number of observations used to compute the median price of cocaine and heroin, standardized prices, and expected purity.

Exploring the Drugs-Crime Connection Within the Electronic Dance Music and Hip Hop Nightclub Scenes in Philadelphia, Pennsylvania, 2005-2006 (ICPSR 21187)
Released/updated on: 2013-01-15
Geographic coverage: United States, Philadelphia, Pennsylvania
Time period: 2005-04-01--2006-12-01
To explore the relationship between alcohol, drugs, and crime in the electronic dance music and hip hop nightclub scenes of Philadelphia, Pennsylvania, researchers utilized a multi-faceted ethnographic approach featuring in-depth interviews with 51 respondents (Dataset 1, Initial Interview Qualitative Data) and two Web-based follow-up surveys with respondents (Dataset 2, Follow-Up Surveys Quantitative Data). Recruitment of respondents began in April of 2005 and was conducted in two ways. Slightly more than half of the respondents (n = 30) were recruited with the help of staff from two small, independent record stores. The remaining 21 respondents were recruited at electronic dance music or hip hop nightclub events. Dataset 1 includes structured and open-ended questions about the respondent's background, living situation and lifestyle, involvement and commitment to the electronic dance music and hip hop scenes, nightclub culture and interaction therein, and experiences with drugs, criminal activity, and victimization. Dataset 2 includes descriptive information on how many club events were attended, which ones, and the activities (including drug use and crime/victimization experiences) taking place therein. Dataset 3 (Demographic Quantitative Data) includes coded demographic information from the Dataset 1 interviews.

Project on Human Development in Chicago Neighborhoods (PHDCN): Deviance of Peers, Wave 1, 1994-1997 (ICPSR 13585)
Released/updated on: 2006-02-17
Geographic coverage: United States, Chicago, Illinois
Time period: 1994-01-01--1997-01-01
The Project on Human Development in Chicago Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. The Deviance of Peers was a self-report interview that obtained information about peer involvement in conventional and delinquent activities. Information about peer pressure to use drugs and/or alcohol was also collected.
