World No Tobacco Day, observed every year on May 31, is a global initiative led by the World Health Organization (WHO) to highlight the health risks associated with tobacco use and advocate for effective policies to reduce tobacco consumption. Established in 1987, the day aims to draw attention to the preventable health impacts of tobacco, including its contribution to respiratory diseases, cancers, and cardiovascular conditions. Supported by the Forum of International Respiratory Societies (FIRS), World No Tobacco Day encourages individuals, communities, and governments to commit to a tobacco-free future and to promote awareness of the benefits of quitting smoking for better lung health and overall well-being.
