Every year, on 31 May, WHO and partners everywhere mark World No Tobacco Day, highlighting the health risks associated with tobacco use and advocating for effective policies to reduce tobacco consumption. Tobacco use is the single most preventable cause of death globally and is currently responsible for killing one in 10 adults worldwide.

The theme for World No Tobacco Day 2013 is: ban tobacco advertising, promotion and sponsorship.

Every year, on 31 May, WHO and partners mark World No Tobacco Day, highlighting the health risks associated with tobacco use and advocating for effective policies to reduce tobacco consumption. Tobacco kills nearly 6 million people each year, of which more than 600 000 are non-smokers dying from breathing second-hand smoke. For World No Tobacco Day 2014, we are calling on countries to raise taxes on tobacco.
