World No Tobacco Day (WNTD) is observed around the world every year on 31 May. It is intended to encourage a 24-hour period of abstinence from all forms of tobacco consumption around the globe. The day is further intended to draw attention to the widespread prevalence of tobacco use and to negative health effects, which currently lead to nearly 6 million deaths each year worldwide, including 600,000 of which are the result of non-smokers being exposed to second-hand smoke.
The member states of the World Health Organization (WHO) created World No Tobacco Day in 1987. In the past twenty one years, the day has been met with both enthusiasm and resistance around the globe from governments, public health organizations, smokers, growers, and the tobacco industry.
WNTD is one of eight official global public health campaigns marked by the WHO, along with World Health Day, World Blood Donor Day, World Immunization Week, World Tuberculosis Day, World Malaria Day, World Hepatitis Day, and World AIDS Day. Each year, the WHO selects a theme for the day in order to create a more unified global message for WNTD. This theme then becomes the central component of the WHO’s tobacco-related agenda for the following year. The WHO oversees the creation and distribution of publicity materials related to the theme, including brochures, fliers, posters, websites, and press releases. Videos were created as a part of the 2008 WNTD awareness campaign for the theme ″Tobacco-free youth″ and published on YouTube, and podcasts were first used in 2009.
