This study assessed the effects of youth-engaging interventions on illegal sales by tobacco retailers near schools in Thailand. The youth were educated and engaged in the planning and implementation of a program to reduce tobacco retailers' illegal sales in the Uttaradit Municipality, Thailand. Intervention components included community education, retailer education, and direct approaches to tobacco retailers. A study included a pretest-posttest control group. The 6-month intervention focused on 114 tobacco retailers. The posttest showed that the percentage of tobacco retailers violating the retail law decreased: tobacco product displays at points of sales decreased from 67.5% to 23.7%, single cigarette sales declined from 71.1% to 36.0%, and tobacco sales to minors decreased from 74.6% to 5.3%. Asking for identification or the buyer's age before selling tobacco increased from 33.3% to 78.1%. The intervention led to a significant reduction in the violation of tobacco retail laws near schools.
