National No-Tobacco Day will be observed in Iran from May 24 to 30, focusing on the theme ‘Revealing Tobacco Industry’s Tricks for a Tobacco-Free Generation’. Each day will address different topics, including public participation, media’s role, family health literacy, and preventive laws against tobacco advertising. A national tobacco prevention program will also launch in around 40 regions, targeting schools and communities to educate students, parents, and educators. This initiative aims to empower youth as tobacco prevention ambassadors. Additionally, World No-Tobacco Day on May 31 will raise awareness about the dangers of tobacco use and deceptive industry practices.
