In 1983 the Nebraska Prevention Center for Alcohol and Drug Abuse began a project to develop and evaluate an educational program designed to discourage young people from taking up the smoking habit and to encourage those who smoke to quit. The second evaluation of this smoking curriculum had two components: a 1-year follow-up evaluation of the curriculum based on an assessment of smoking attitudes, knowledge, and behavior of the students taught in the first year of this project; and an evaluation of the effectiveness of a slightly revised version of the curriculum taught to a different group of classes in the second year of the project. Subjects included 736 students at the 1-year followup. This longitudinal project presents significant encouragement to those involved in tobacco education. with 1 day of inservice and a well-prepared curriculum, a typical teacher can effect significant knowledge increases in students. This project showed that when teachers do present an educational program, well-grounded in theory, that long-term effects are visible as much as a year later. These long-term effects include an increase in self-reported ability by young people to resist pressures to smoke, a reduction in the number of people who think they will smoke in the future, and a reduction in the expected rate of smoking behavior.
