This prevention resource guide (compiled from a variety of publications and data bases and representing the most currently available information) focuses on secondary school students, and is divided into four sections. The first section contains facts from current research about substance abuse prevention for secondary school students. For example, if a teenager's friends are using alcohol or other drugs, the possibility of use increases substantially. Peers are known to have a powerful effect on an individual's use of alcohol or other drugs. The second section contains materials that have been reviewed for scientific accuracy based on the latest available scientific findings, appropriateness for the target audience as described by the developers of the materials, and conformance to public health principles and related policies. The underlying guidelines used for the review of materials are based on the principle of "do no harm." All materials contain a clear non-use message for youth. The third section contains abstracts of government publications journal articles, and other publications dealing with substance abuse prevention for this age group. The fourth section lists names, addresses, and phone numbers for pertinent resources such as the American Council for Drug Education, National Association of Teen Institutes, National Clearinghouse for Alcohol and Drug Information, and the Parents' Resource Institute for Drug Education, Incorporated.
