National substance abuse epidemiology initiatives in the United States: what works for what.

Data concerning the epidemiology of drug abuse in the United States are presented in this paper. The paper includes an integrating approach from various data sources: national, state, and local level; surveillance systems; and outbreak investigations. An analysis of trends and patterns of drug abuse are discussed, both from the perspective of historical development and the current situation. Analyses focus on changes in levels of use for different drugs as well as changes in user characteristics and consequences of use. Current studies concerning the epidemiology of drug abuse in special populations and findings from recent field investigations are presented. Future research directions in the field of epidemiology from a national perspective are outlined.

Epidemiology of drug abuse in the United States: a summary of methods and findings.

Epidemiology has recently been used to effectively track and analyze drug abuse patterns. This article generally describes methods used in the United States for estimating and monitoring drug abuse. It outlines the advantages and limitations of such data sources as surveys, indicators, and ethnography, and briefly explores the work and utility of local, national, and international drug surveillance networks. In addition, it describes national and local patterns of heroin, cocaine, and marijuana abuse.

Epidemiology of drug abuse: an overview.

Issues regarding the use of epidemiology in drug abuse research are discussed and systems for monitoring national trends and identifying risk factors are described. Data indicate a general decline in marijuana use among youth, a cohort aging effect among heroin and marijuana users, and increased prevalence and health consequences associated with cocaine use.

Trends in prevalence and consequences of cocaine use.

A variety of data sources and research studies are used to examine changes in the prevalence of cocaine use and assess the population at risk. The issues of progression to more intensified use of cocaine and the use of other drugs in combination with cocaine are investigated. Consequences of cocaine use are discussed, as is the potential impact of changing routes of administration on both the frequency and severity of those consequences.

Trends in drug use and crime and their relationship in an arrested population.

Trends in drug use and criminal charges of 44,223 consecutive admissions to the District of Columbia Superior Court lock-up between December 1971 and April 1975 were analyzed. While the number of persons arrested and admitted to the lock-up remained relatively constant during this time, drug use as measured by positive urinalysis declined substantially in 1973 and remained at a lower level through 1975. Heroin use showed a decline similar to the overall trends in 1973, but began to increase in mid-1974. Arrestees who were drug positive were generally less likely to be charged with major crimes of violence than those who were drug negative. Exceptions to this pattern as well as trends in drug use and crime in the arrested population are discussed.
