World No Tobacco Day (May 31, Gregorian) is observed annually on May 31. This day was officially designated in the Gregorian calendar in 1988 by the World Health Organization as an international event to draw global attention to the consequences of tobacco use and its impact on public health. The purpose of establishing this day was to raise awareness about the dangers of smoking and other tobacco products, and to encourage reduction in their use worldwide. In its first year, the World Health Organization promoted educational campaigns and public messages to inform people about the health risks associated with tobacco, including increased chances of heart disease, respiratory illnesses, and cancers. In subsequent years, World No Tobacco Day has served as an opportunity for awareness campaigns, restrictions on tobacco advertising, and support for tobacco control policies in many countries. The day continues to play a significant role in engaging policymakers, health professionals, and the public in efforts to address tobacco consumption.
