Prevention Center Papers are occasional publications of the Nebraska Prevention Center for Alcohol and Drug Abuse. Their purpose is to make available information that would not otherwise be easily accessible.

This Prevention Center Paper should be considered a working document and does not reflect the official policy or position of the University of Nebraska-Lincoln, The U.S. Centers for Disease Control, the Nebraska Department of Education, or Health Education, Inc.

Prevention Center Papers are produced for a limited readership to stimulate discussion and generate a flow of communication between the Prevention Center and those interested in the broad field of disease prevention and health promotion.
