Protocol for a Cluster Randomized Controlled Trial to Reduce Susceptibility to Tobacco Use Among School Going Adolescents in a South-Indian District-(Project TEACH).

Background: Adolescents are susceptible to using tobacco because of early exposure to tobacco through family members, easy access, or peer pressure. School-based educational programs are crucial for raising awareness of the harms of tobacco, thus preventing its uptake among adolescents. Studies conducted recently have recognized the need to bring change and reinforce ongoing school-based anti-tobacco education programs.
