While individuals are not usually able to provide a wide range of prevention services on their own, they can have a positive impact in many ways within their homes, their schools and their communities. One way is by understanding and supporting the "big picture" of prevention and assisting with programs whenever possible. Helping other parents understand the implications of allowing their children to have parties where alcohol is served or contacting a legislator about proposed alcohol, tobacco or other drug legislation may make a substantial difference in preventing problems related to the use of these substances. Individuals also can serve on boards, coalitions and other community and school groups that affect prevention policies and programs. Many prevention efforts take place in churches; through youth groups, such as the Boy Scouts, Girl Scouts and others; and through recreational and sporting activities. However one decides to get involved with prevention, becoming well informed on the subject is an important first step toward promoting positive benefits for individuals, families and communities.
