Project Toward No Tobacco Use (Project TNT)

Program Goals

Project Toward No Tobacco Use (Project TNT) is a comprehensive, classroom-based curriculum designed to prevent or reduce tobacco use. It is devised to counteract several different risk factors for tobacco use simultaneously, because the behavior is associated with multiple risk factors.

Target Population

Project TNT targets a wide variety of youths who may have different risk factors influencing their tobacco use. It is designed for fifth through ninth grade youths (ages 10–14).

Program Components

Project TNT teaches awareness of misleading social information, develops skills that counteract social pressure to use tobacco, and provides information about the physical consequences of tobacco use, such as addiction.

Implementing Project TNT involves the following activities:

  • A comprehensive, 10-day, classroom-based, social-influences program—plus two booster sessions—that examines media, celebrity, and peer portrayal of tobacco use
  • Training in active listening, effective communication, and general assertiveness development, along with methods for building self-esteem
  • Education on the course of tobacco-related addiction and diseases; correction of inflated tobacco-use prevalence estimates
  • Education on tobacco-specific, cognitive coping skills, and assertive refusal techniques; practicing ways to counteract media portrayals of tobacco use, including social-activism letter-writing to make a public commitment to not using tobacco products
  • Use of homework assignments, a classroom competition (i.e., the “TNT Game”), and a two-lesson booster program
  • Longitudinal assessment material

Key Personnel

Trained teachers in a classroom setting deliver Project TNT to standard class sizes.

Study 1

Substance Use

Results from immediate posttest to 1-year follow-up for the five groups were as follows:

  • For both trial and weekly use of cigarettes, the informational social influence group, physical consequences, and combined groups were superior to the normative and control groups.

  • For trial of smokeless tobacco, two of the three intervention groups were superior to the informational social influence and control groups.

  • For weekly use of smokeless tobacco, the combined condition was superior to all other conditions.

A 2-year follow-up (Dent and colleagues 1995) analyzed data for subjects when they were ninth graders and reported maintenance of initial intervention effects (lower trial and weekly use of cigarettes) in the combined and physical consequences groups and lower weekly use of smokeless tobacco for the combined condition.
