Effectiveness of Comics to Promote Tobacco-related Knowledge, Attitudes and Behaviours Among Primary School Students

The goal of this pilot RCT is to evaluate the effectiveness of comics containing tobacco-related content in improving tobacco-related knowledge and attitudes among Hong Kong primary school students. The main questions it aims to answer are: * Is the intervention (i.e. comics) effective in improving tobacco-related knowledge (including alternative smoking products (ASPs) and tobacco control development in the world and Hong Kong) compared to controls (i.e. information sheets)? * Is the intervention (i.e.comics) effective in improving tobacco-related attitudes and intentions (including ASPs and tobacco control development in the world and Hong Kong) compared to controls (i.e. information sheets)? Researchers will compare the questionnaire results from students to see if intervention groups (students reading comics) will have better tobacco-related knowledge, higher anti-tobacco attitudes and lower intention to smoke compared to the control group (students reading information sheets).
