This case study analyzes the effectiveness of the Quit Campaign in Australia and Singapore, focusing on the impact of anti-smoking advertisements on young smokers. It employs exploratory and conclusive research methods, including focus groups and longitudinal studies, to evaluate the campaign's success. The study highlights cultural differences in attitudes towards smoking and anti-smoking campaigns between the two countries, noting Singapore's reluctance to express views compared to Australia's openness. The research identifies issues such as the 'boomerang effect' in Singapore, where anti-smoking ads sometimes encourage smoking, and the unreliability of participant responses over time. The case study concludes with recommendations to encourage youth to quit smoking, including promoting healthy lifestyles, critical observation of tobacco ads, and creating tobacco-free campuses, emphasizing the importance of societal involvement, counseling, and government policies to combat smoking.
