In an effort to raise awareness about the dangers of tobacco use, May 31 is World No Tobacco Day (WNTD), an annual event that encourages people around the world to abstain from all tobacco consumption for 24 hours.
Since 1987, the World Health Organization (WHO) has been shining the spotlight on the harmful consequences of tobacco use and exposure as well as business practices of tobacco companies. In 1988, a resolution was passed declaring each May 31st World No Tobacco Day.
Nations and organizations around the world participate in the observance by participating in a wide variety of activities. While a different theme is adopted each year, every theme highlights the harmful effects of tobacco use and exposure. This year's theme is Tobacco Taxes. The theme for 2013 was "Ban Tobacco Advertising, Promotion and Sponsorship" while the theme for 2012 was “Tobacco Industry Interference.”
