The DC Metropolitan Area Drug Study (DCMADS) was

conducted in 1991, and included special analyses of homeless and

transient populations and of women delivering live births in the DC

hospitals. DCMADS was undertaken to assess the full extent of the

drug problem in one metropolitan area. The study was comprised of 16

separate studies that focused on different sub-groups, many of which

are typically not included or are under-represented in household

surveys.The DCMADS: Household and Non-household Populations

examines the prevalence of tobacco, alcohol, and drug use among

members of household and non-household populations aged 12 and older

in the District of Columbia Metropolitan Statistical Area (DC

MSA). The study also examines the characteristics of three

drug-abusing sub-groups: crack-cocaine, heroin, and needle users. The

household sample was drawn from the 1991 National Household Survey on

Drug Abuse (NHSDA). The non-household sample was drawn from the

DCMADS Institutionalized and Homeless and Transient Population

Studies. Data include demographics, needle use, needle-sharing, and

use of tobacco, alcohol, cocaine, crack, inhalants, marijuana, hallucinogens, heroin, sedatives, stimulants, psychotherapeutics (non-medical use), tranquilizers, and analgesics.This study has 1 Data Set.

The primary objective of the National Pregnancy and Health

Survey (NPHS) was to produce national annual estimates of the

percentages and numbers of mothers of live newborns in the United

States who used selected licit and illicit drugs in the 12 months

prior to delivery. A further objective was to describe patterns of

prenatal substance use among demographic subgroups of

women. Information on demographic and socioeconomic characteristics,

obstetric history, and drug treatment of women who delivered infants

at sampled hospitals was obtained through an interviewer-administered

questionnaire, while data on substance use before and during pregnancy

were collected through a questionnaire completed by the respondent and

concealed from the interviewer. Respondents were asked about use of

the following substances: alcohol, amphetamines, analgesics, cocaine,

crack cocaine, barbiturates, hallucinogens, hashish, heroin,

marijuana, methadone, methamphetamine, sedatives, stimulants, tobacco,

and tranquilizers. Additionally, information was collected on the

respondent's pregnancy, prenatal care, delivery, previous pregnancies,

and background. Additional data were obtained from the mothers' and

infants' medical records. Urine specimens collected routinely by the

hospital on obstetric admissions were tested for selected

drugs. Finally, in a subsample of six hospitals, hair specimens were

requested from respondents to evaluate the potential of hair as a

source of toxicological data in future studies.This study has 1 Data Set.

The California Drug and Alcohol Treatment Assessment

(CALDATA) was designed to study the costs, benefits, and effectiveness

of the state's alcohol and drug treatment infrastructure (recovery

services) and specifically to assess (1) the effects of treatment on

participant behavior, (2) the costs of treatment, and (3) the economic

value of treatment to society. Data were collected on participants

(clients) across four types of treatment programs, or modalities:

residential, residential "social model," nonmethadone outpatient, and

outpatient methadone (detoxification and maintenance). Data were

collected in two phases. In Phase 1, treatment records were abstracted

for clients who received treatment or were discharged between October

1, 1991, and September 30, 1992. In Phase 2, these clients were

located and recruited for a follow-up interview. The CALDATA design

and procedures included elements from several national treatment

outcome studies including the Drug Services Research Survey, Services Research Outcomes Study, National

Treatment Improvement Evaluation Study, and Drug Abuse

Treatment Outcome Study. The record abstract was designed

to collect identifying and locating information for interview

reference during the personal interviewing phase. The abstract also

collected demographic, drug, or alcohol use, and treatment and service

information. The follow-up questionnaire covered time periods before,

during, and after treatment and focused on topics such as ethnic and

educational background, drug and alcohol use, mental and physical

health, HIV and AIDS status, drug testing, illegal activities and

criminal status, living arrangements and family issues, employment and

income, and treatment for drug, alcohol, and mental health

problems. Drugs included alcohol, barbiturates, benzodiazepines,

cocaine powder, crack, downers, hallucinogens, heroin, illegal

methadone, inhalants, LSD, marijuana/hashish/THC, methamphetamines and

other stimulants, narcotics, over-the-counter drugs, PCP, ritalin or

preludin, and sedatives/hypnotics. CALDATA was originally known as the

California Outcomes Study (COS).This study has 1 Data Set.

The National Household Survey on Drug Abuse (NHSDA) series

measures the prevalence and correlates of drug use in the United

States. The surveys are designed to provide quarterly, as well as

annual, estimates. Information is provided on the use of illicit

drugs, alcohol, and tobacco among members of United States households

aged 12 and older. Questions include age at first use as well as

lifetime, annual, and past-month usage for the following drug classes:

marijuana, cocaine (and crack), hallucinogens, heroin, inhalants,

alcohol, tobacco, and nonmedical use of prescription drugs, including

pain relievers, tranquilizers, stimulants, and sedatives. The survey

covers substance abuse treatment history and perceived need for

treatment, and includes questions from the Diagnostic and Statistical

Manual (DSM) of Mental Disorders that allow diagnostic criteria to be

applied. Respondents are also asked about personal and family income

sources and amounts, health care access and coverage, illegal

activities and arrest record, problems resulting from the use of

drugs, and needle-sharing. Questions introduced in previous NHSDA

administrations were retained in the 1999 survey, including questions

asked only of respondents aged 12 to 17. These "youth experiences"

items covered a variety of topics, such as neighborhood environment,

illegal activities, gang involvement, drug use by friends, social

support, extracurricular activities, exposure to substance abuse

prevention and education programs, and perceived adult attitudes

toward drug use and activities such as school work. Also retained were

questions on mental health and access to care, perceived risk of using

drugs, perceived availability of drugs, driving behavior and personal

behavior, and cigar smoking. Questions on the tobacco brand used most

often were introduced with the 1999 survey. Demographic data include

gender, race, age, ethnicity, marital status, educational level, job

status, veteran status, and current household composition.This study has 1 Data Set.

This series measures the prevalence and correlates of drug

use in the United States. The surveys are designed to provide

quarterly, as well as annual, estimates. Information is provided on

the use of illicit drugs, alcohol, anabolic steroids, and tobacco

among members of United States households aged 12 and older. Data are

also provided on treatment for drug use and on illegal activities

related to drug use. Questions include age at first use, as well as

lifetime, annual, and past-month usage for the following drug classes:

marijuana, inhalants, cocaine, hallucinogens, heroin, alcohol, tobacco,

and nonmedical use of psychotherapeutics. Respondents were also asked

about problems resulting from their use of drugs, alcohol, and

tobacco, their perceptions of the risks involved, insurance coverage,

and personal and family income sources and amounts. Demographic data

include gender, race, ethnicity, educational level, job status, income

level, household composition, and population density.This study has 1 Data Set.

study examines the prevalence of illicit drug, alcohol, and tobacco

use among members of the homeless and transient population aged 12 and

older in the Washington, DC, Metropolitan Statistical Area (DC

kitchens and food banks, major cluster encampments, and literally

homeless people. Data from the questionnaires include history of

homelessness, living arrangements and population movement, tobacco,

drug, and alcohol use, consequences of use, treatment history, illegal

behavior and arrest, emergency room treatment and hospital stays,

physical and mental health, pregnancy, insurance, employment and

finances, and demographics. Drug specific data include age at first

use, route of administration, needle use, withdrawal symptoms,

polysubstance use, and perceived risk.This study has 1 Data Set.
