There have been a number of tobacco prevention programs developed and tested in the past few years, and some of the comprehensive programs have been promoted by the Office on Smoking and Health at the Centers for Disease Control (CDC). However, the use of these programs and integration into school-based curriculum has been lacking due to a number of factors. We are proposing to develop an interactive computer-based program for tobacco prevention aimed at middle school students. The CD-ROM is designed to be an adjunct to the existing health education curriculum provided for 6th through 8th grade students.
