- Conduct a randomized trial to assess the effectiveness of the Tobacco Free Town (TFT) program at preventing or delaying initiation of tobacco by 7th grade, and decreasing behavioral intentions and willingness to use tobacco, as compared to the usual tobacco-prevention curriculum implemented in schools. The TFT program consists of 17 effective components delivered in eight sessions over a four-week period in 5th grade with two booster sessions delivered within a one-week period in 6th grade.
