This guide accompanies Join Together's recommendations for drug and alcohol abuse prevention for policymakers and communities. It presents strategic examples of how major institutions and residents in communities have paid attention to substance abuse and worked to overcome its effects. Part 1 contains the recommendations and key policies presented by the Panel on Preventing Substance Abuse. A community action example illustrating each recommendation is described, and resources are suggested for communities that wish to pursue the prevention principles pertinent to the individual recommendation. The recommendations include: (1) comprehensive strategic planning supported by long-term community commitment and laws and regulations that promote collaboration; (2) working to incorporate prevention principles and themes into existing programs and initiatives; (3) establishing programs to prevent, identify, and reduce violence and traumatic injury associated with drug and alcohol use; (4) revising federal, state, and local policies to ensure that illegal access to alcohol and tobacco is eliminated; (5) improving efforts to collect and disseminate information about drugs and alcohol; and (6) increasing accountability and evaluation of prevention efforts. The second part of the guide offers additional resources, including lists of 13 organizations, 9 publications, 11 clearinghouses, and 4 online services that can assist community prevention planning and activities.
