摘 要：Adolescents are subjected to influences that may increase their risk for substance use or protect them from it. Substance use prevention programs are designed to reduce the influence of risk factors and increase the influence of protective factors. Parents can also affect substance use through conversations that they have with their children. Substance use prevention messages and programs are also provided through the media, schools, and other sources that have all been shown to have an association with alcohol and illicit drug use. Providing adolescents with credible, accurate, and age-appropriate information about the harm associated with substance use is a key component in prevention programming because youth perception of the risks associated with substance use are related to their rates of substance use. Prevention programming can be made more effective by gaining a better understanding how youths receive prevention messages. Similarly, prevention programming can be better targeted to address underserved populations if the demographic characteristics of youths not exposed to prevention messages or programs are known.
