Originally, the mission of SADD was to help young people say "No" to drinking and driving. The mission has since expanded. Today, the mission of SADD is to provide students with the best prevention tools possible to deal with the issues of underage drinking, other drug use, impaired driving, and other destructive decisions. Students have told us that positive peer pressure, role modeling, and environmental strategies can prevent other destructive decisions and set a healthier, safer course for their lives. And that is why SADD has become a peer-to-peer education, prevention, and activism organization dedicated to preventing destructive decisions, particularly underage drinking, other drug use, risky and impaired driving, teen violence, and teen suicide.
