The Join Together National Advisory Committee was created to help communities be more effective in developing and implementing strategies to reduce the harm from substance abuse. Join Together conducted this national report to describe community coalitions and to assess their contributions and needs. The findings are intended to help coalitions, local leaders, and public policy makers strengthen their capacity and commitment to reduce the harm from substance abuse. Surveys were sent to coalition leaders throughout the nation in 1992 and 1993. Results, drawn from the 2,196 responding groups that identified themselves as lead coalitions, showed that: (1) more than 90 percent of coalition leaders support increased taxes on alcohol, lower legal blood-alcohol concentration level for drivers, restrictions on alcohol advertising and funds for treatment on demand; (2) community coalitions give at least as much attention to alcohol abuse, especially among young people, as to illegal drugs; (3) the issues and activities that coalitions emphasize (prevention, public awareness, early intervention, treatment, and aftercare) vary depending upon the sponsoring organization of the coalition; and (4) the majority of coalitions face problems such as leadership turnover, unstable funding, and evolving organization governance structure. A copy of the Join Together survey is included; the survey method is appended. (SR)
