Underage drinking presents a serious health risk not only to young people themselves but to entire communities. This program guide is designed to help communities establish their own underage drinking prevention programs. Community norms, actions, and attitudes toward alcohol affect young people, as do the ways in which alcohol is promoted. Solutions to illegal drinking are dependent on the entire community working together to create healthy environments in which young people can make the right choices. This guide will help community organizers develop special events which encourage healthy lifestyle choices. Some of the issues addressed here include the delivery of messages at special events, implementing a teen drinking prevention program event, developing an effective partnership with event organizers, selecting event activities, creating a mini-event, making materials for the program, and ensuring a safer event for young people. Also described are programs in four cities which promoted teenage abstinence from alcohol. (RJM)
