Developed jointly by the American Cancer Society, American Heart Association, and American Lung Association, TATU is a tobacco prevention program designed to help teens teach younger children about the hazards of tobacco use and the benefits of making healthy choices. Recent focus groups have shown that teens don’t want to talk to their peers about tobacco. However, they are eager to talk to younger kids about tobacco issues. They like the idea of being an authority and discouraging tobacco use among younger children. TATU-trained teens provide tobacco prevention education lessons to 4th through 6th-grade students. TATU incorporates these findings by enlisting- ing teens to help young children remain tobacco-free.
