World No Tobacco Day

World No Tobacco Day, observed on May 31st, is a World Health Organization observance raising global awareness about the significant health risks associated with tobacco use and encouraging policies to reduce tobacco consumption worldwide. The WHO established the observance in 1987, recognizing tobacco use as one of the leading preventable causes of death worldwide, responsible for millions of deaths annually from conditions including various cancers, heart disease, stroke, and chronic respiratory illness, with the organization estimating that tobacco kills roughly half of its long-term users if consumption patterns continue unchanged. Each year, the WHO selects a specific theme for the observance, addressing topics ranging from the tobacco industry's marketing tactics targeting young people, the environmental impact of tobacco cultivation and cigarette butt litter, the dangers of secondhand smoke exposure, or the growing use of e-cigarettes and vaping products, which the WHO has increasingly highlighted as an emerging public health concern despite industry marketing sometimes framing them as a safer alternative to traditional cigarettes. The observance coincides with and supports broader global tobacco control efforts, including the WHO Framework Convention on Tobacco Control, an international treaty adopted in 2003 that established coordinated strategies among signatory countries for tobacco taxation, advertising restrictions, packaging warning labels, and public smoking bans. Public health organizations, hospitals, and governments worldwide use the day to promote smoking cessation resources and tobacco control policy advocacy.
