The substance use system: social and neighborhood environments associated with substance use and misuse.

Substance use theory and practice have traditionally focused on individuals who misuse substances or who are at risk for substance misuse, but this emphasis is shifting. The present study views both substance use and misuse systematically, assessing the relationships between the physical and social environments and substance use and misuse in dynamic interplay. This substance use system was examined through a survey of approximately 10,000 persons, aged 22-44, from primarily inner-city neighborhoods in the United States. Individual indicators such as race, sex, age, socioeconomic status, education, and religious service attendance relate to both the physical and interpersonal environments, even when each is controlled for the others. Qualities of both environments are strongly associated with substance dependency, even after individual indicators are controlled. These findings suggest the difficulty of bringing about change in drug and alcohol use without fundamental change in the environments where use takes place.

Survey estimates of drug-use trends in urban communities: general principles and cautionary examples.

Surveys to depict substance abuse rates and monitor trends in specific areas have become increasingly important policy tools. Yet, as illustrated by two national multiwave surveys, using small sample survey data and making longitudinal comparisons is fraught with interpretative problems. In the case of the metropolitan area “over-sample” of the National Household Survey on Drug Abuse, for example, interpreting apparent declines in drug use has to take account of the devastating effects of Hurricane Andrew in the Miami Metropolitan area. In the case of a 41-community survey sponsored by the Robert Wood Johnson Foundation to evaluate substance abuse prevention, the difficulty is how to interpret small differences in drug use, which seem to follow no reasonable pattern with respect to treatment or comparison sites. Inferences from such surveys are confounded with statistical anomalies and unforeseen events. They are limited by the sample size. In part, the solution to these problems is to use other survey and nonsurvey data to validate their conclusions and to note their limitations.
