World No Tobacco Day is observed on May 31 every year to highlight the risk associated with the use of tobacco. The annual campaign is an opportunity to raise awareness to help reduce use and protect the health of the people.

The World Health Organization (WHO) promotes World No Tobacco Day each year to highlight the health risks of using tobacco and to encourage governments to put policies into action that help to reduce smoking and the use of other tobacco products.

According to WHO, tobacco use kills more than 8 million people around the world each year. Smoking any kind of tobacco reduces lung capacity and increases the severity of respiratory diseases. Covid19 is an infectious disease that primarily attacks the lungs. Due to which, research suggests that smokers are at higher risk of developing severe Covid-19 outcomes and death.

Every year World No Tobacco is observed with a different theme; this year, the theme of World no Tobacco Day is 'Protecting youth from industry manipulation and preventing them from tobacco and nicotine use'.

The theme of Anti-Tobacco Day in 2019 was 'Tobacco and Lung Health' and in 2018, it was 'Tobacco and heart disease'.
