This study assesses the consequences for offenders of various drug enforcement strategies employed by the San Diego Police Department and profiles the factors that characterize street-level and mid-level dealers, drug users, and the drug market. The drug enforcement strategies examined include the use of search warrants, body wires, police decoys, surveillance, officer buys and sells, wiretaps, and sweeps. Measures of the consequences of arrests include drug and property seizures, convictions, and sentences. The data were drawn from police and court records of drug arrests made by three special sections of the police department in San Diego, California. Additionally, data were collected through personal interviews conducted at the time of arrest with a subsample of persons arrested for drug charges. The arrest tracking file, Part 1, contains demographic information about the offenders, including criminal history and gang membership, as well as data on each arrest through final disposition, charges, and sentencing. The interview portion of the study, Part 2, provides information about the demographics and characteristics of drug users and dealers, criminal history and drug use history, current arrest information, and offenders' opinions about drug use, drug sales, police strategies, and the drug market.

These data were collected to evaluate the Demand Reduction Program, a program initiated in Maricopa County, Arizona, in 1989 to combat drug abuse. A consortium of municipal, county, state, and federal law enforcement agencies developed the program, which stressed user accountability. The Demand Reduction Program had two objectives: (1) to create community-wide awareness of the severity of the drug problem and to alert drug users to the increased risk of legal sanctions, and (2) to adopt a zero-tolerance position of user accountability through an emphasis on increased and coordinated law enforcement activities directed against individual offenders and special treatment programs in lieu of prosecution. Part 1 of the collection, Demand Reduction Program Data, provides information on prosecutor's disposition, arrest date, submitted charges, filed charges, prior charges, disposition of charges, drugs offender used in last three months, information on prior drug treatment, type of attorney, and arrestee's age at arrest, sex, marital status, income, and living arrangement. Part 2 is a Citizen Survey conducted in January 1990, ten months after the implementation of the Demand Reduction Program. Adult residents of Maricopa County were asked in telephone interviews about their attitudes toward drug use, tax support for drug treatment, education, and punishment, their knowledge of the Demand Reduction Program, and demographic information. Parts 3 and 4 supply data from surveys of Maricopa County police officers, conducted in March 1990 and April 1991, to measure attitudes regarding the Demand Reduction Program with respect to (1) police effort, (2) inter-agency cooperation, (3) the harm involved in drug use, and (4) support for diversion to treatment. The two police surveys contained identically-worded questions, with only a small number of different questions asked the second year. Variables include officer's rank, years at rank, years in department, shift worked, age, sex, ethnicity, education, marital status, if officer was the primary or secondary wage earner, officer's perception of and training for the Demand Reduction Program, and personal attitudes toward drug use. Part 5 provides arrest data from the Maricopa County Task Force, which arrested drug users through two methods: (1) sweeps of public and semi-public places, and (2) "reversals," where drug sellers were arrested and replaced by police officers posing as drug sellers, who then arrested the drug buyers. Task Force data include arrest date, operation number, operation beginning and ending date, operation type, region where operation was conducted, charge resulting from arrest, Demand Reduction Program identification number, and arrestee's sex, race, and date of birth.

This data collection investigates the ways in which police use reports of drug-related crimes provided by residents of high drug/crime areas and how willing residents of these areas are to report such crimes to the police. Structured interviews were conducted by telephone with police representatives in most of the nation's 50 largest cities and in person with residents and police officers in high drug/crime districts in each of four major cities: Newark, Chicago, El Paso, and Philadelphia. Police department representatives were queried about the usefulness of citizen reports, reasons for citizens' reluctance to make reports, how the rate of citizen reports could be improved, and how citizen reports worked with other community crime prevention strategies. Residents were asked about their tenure in the neighborhood, attitudes toward the quality of life in the neighborhood, major social problems facing the neighborhood, and quality of city services such as police and fire protection, garbage collection, and public health services. Additional questions were asked about the amount of crime in the neighborhood, the amount of drug use and drug-related crime, and the fear of crime. Basic demographic information such as sex, race, and language in which the interview was conducted is also provided.

This study investigated changes in the geographic concentration of drug crimes in Cleveland from 1990 to 2001. The study looked at both the locations of drug incidents and where drug offenders lived in order to explore factors that bring residents from one neighborhood into other neighborhoods to engage in drug-related activities. This study was based on data collected for the 224 census tracts in Cleveland, Ohio, in the 1990 decennial Census for the years 1990 to 1997 and 1999 to 2001. Data on drug crimes for 1990 to 1997 and 1999 to 2001 were obtained from Cleveland Police Department (CPD) arrest records and used to produce counts of the number of drug offenses that occurred in each tract in each year and the number of arrestees for drug offenses who lived in each tract. Other variables include counts and rates of other crimes committed in each census tract in each year, the social characteristics and housing conditions of each census tract, and net migration for each census tract.

These data were collected to explore connections between street gangs and drug distribution. The research objectives for this study were (1) to assess the magnitude of gang involvement in cocaine and other drug sales in two suburban cities, (2) to compare the characteristics of gang-involved drug sale incidents with those without gang involvement, (3) to assess the generalizability of findings on cocaine to other drugs, and from urban to more suburban settings, and (4) to translate the implications of the research findings into the development of law enforcement strategies. Law enforcement arrest records and gang membership records were obtained for two study sites, Pasadena and Pomona, California. Part 1, the incident-level file, supplies information on arrest incidents qualifying as drug sales. Variables in the file include presence at arrest of violence, guns, cash, and drugs, types of charges, gang characteristics of the incident, racial/ethnic makeup of arrestees, gender of arrestees, and gang affiliation of arrestees. Part 2, the participant-level file, supplies data on each participant in each incident. Variables in this file include gender, ethnicity, gang membership status, and charges.

This study was an evaluation of the Breaking the Cycle (BTC) demonstration projects conducted in Birmingham, Alabama, Jacksonville, Florida, and Tacoma, Washington, between 1997 and 2001. The BTC demonstrations tested the feasibility and impact of systemwide interventions to reduce drug use among offenders by identifying and intervening with drug-involved felony defendants. This study contains data collected as part of the impact evaluation of BTC, which was designed to test the hypotheses that BTC reduced criminal involvement, substance abuse, and problems related to the health, mental health, employment, and families of felony drug defendants in the demonstration sites. The evaluation examined the relationship between changes in these areas and characteristics of the participants, the kinds and levels of services and supervision they received, and perceptions of defendants about the justice system's handling of their cases. It also assessed how BTC affected case handling and the length of time required to reach a disposition, the number of hearings, and the kinds of sentences imposed. The impact evaluation was based on a quasi-experimental comparison of defendants in BTC with samples of similar defendants arrested in the year before BTC implementation. Interviews were conducted with sample members and additional data were gathered from administrative records sources, such as the BTC programs, arrest records, and court records.

This neighborhood-level study sought to explore the effect of cultural disorganization, in terms of both weakened conventional culture and value heterogeneity, on informal social control, and the extent to which these effects may be conditioned by the level of drug use in the neighborhood. Data for Part 1 were collected from face-to-face and telephone interviews with households in the targeted sample. Part 2 is comprised of data collected from the United States Census 1990 Summary Tape File 3A (STF3A) as well as the United States Census 2000 Population counts, Lexington and Louisville police crime incident reports, and police data on drug arrests. The responses gleaned from the survey used in Part 1 were aggregated to the census block group level, which are included in Part 2.

The Probationers in Recovery (PIR) program, developed by the San Diego County Probation Department, targeted high-risk, drug-abusing offenders with the goal of controlling offender behavior without increasing risks to communities. This evaluation of PIR was based on a quasiexperimental design that compared program activities and outcomes for two matched groups of high-risk probationers receiving different levels of service and supervision. The assessment included both a process evaluation to discover if expected service levels were implemented as designed, and an impact evaluation to assess the effectiveness of drug treatment within an intensive community supervision program. The experimental group included 209 PIR participants who received intensive community supervision and drug treatment, and the control group consisted of 151 probationers who were assigned to regular high-risk probation caseloads and who met the PIR screening criteria. The samples were selected from probationers entering community supervision from February to December 1991. The length of the PIR program varied, but for purposes of analysis the minimum time in the program to represent the intervention period was set at eight months, including relapse prevention. A comparable period was used for the control group. The subsequent six-month period was used to measure the effects of PIR and regular high-risk probation after intervention. Intake interviews were conducted with a subsample of 96 probationers in PIR and 80 in the control group (Part 1). The interviews were conducted within the first two weeks after intake. Follow-up interviews were conducted with these probationers after they had completed eight months of PIR or regular high-risk probation to measure experiences on probation and changes in behavior and attitudes (Part 2). Follow-up interviews were completed with 47 probationers from the experimental group in the PIR program and 35 in the control group. The case tracking portion of the study involved the review of probation, treatment, and state and local criminal history files (Part 3). Data on technical violations and arrests for new crimes were compiled for the following time periods: (1) six months prior to the instant offense (the baseline), (2) the first eight months of community supervision (the in-program period), (3) the six months after intervention, and (4) the combined 14-month period. The initial interview (Part 1) included questions regarding sociodemographic characteristics, current offense, awareness of probation conditions ordered, perceived consequences for violations of probation, drug use and drug history, prior drug treatment and treatment needs, criminal history, expectations regarding the probation term, opinions regarding probation and treatment, daily activities prior to the current offense, current life satisfaction, and prospects for the future. Questions on the follow-up interview (Part 2) focused on changes in probationers' personal lives (e.g., employment, income, education, marital status, living situation, and relationships with family and friends), technical probation violations and new offenses committed during the eight-month period, sanctions imposed by probation staff, contacts with probation and treatment staff, changes in drug use and daily activities, expectations with regard to remaining crime- and drug-free in the future, attitudes regarding probation and treatment, treatment needs, and significant life changes over the eight-month period. Variables in the tracking data file (Part 3) include sociodemographic characteristics, current offense and sentence imposed, probation conditions ordered, drug use history, offense and probation violations occurring before, during, and after an eight-month probation period, custody time, changes in level of probation supervision, and program interventions such as drug tests, services delivered, and sanctions imposed.
