31 May is observed as a World No Tobacco Day Every year by World Health Organization and global partners. The yearly campaign is an opportunity to raise awareness on the harmful and deadly effects of tobacco use and second-hand smoke exposure, and to discourage the use of tobacco in any form.

Theme for 2021 World No-Tobacco Day is “Commit to quit.” 

This yearly celebration informs the public on the dangers of using tobacco, the business practices of tobacco companies, what WHO is doing to fight the tobacco epidemic, and what people around the world can do to claim their right to health and healthy living and to protect future generations.


On 15th May 1987, WHO passed a resolution, calling for 7th April 1988, to be the first World No Smoking Day. This date was chosen as it was the 40th anniversary of the World Health Organization. Then on 17th May 1989, the WHO passed a resolution calling for May 31 to be annually known as World No Tobacco Day. World No Tobacco Day has been observed every year on 31st May since the 1989.
