World No Tobacco Day May 31, 2016 is the 29th World No Tobacco Day initiated by the World Health Organization. Currently, 350 million people in China are smokers, and there are another 750 million victims of secondhand smoke; 1.8-2 million Chinese smokers die of tobacco-related diseases every year; and 5-6 million smokers worldwide die of tobacco-related diseases every year. The aim of the campaign is to remind the world that smoking is hazardous to health, to call on smokers around the world to give up smoking, and to call on all tobacco producers, sellers and the entire international community to act together in the anti-smoking campaign to create a tobacco-free environment for mankind. According to WHO, smoking kills nearly 6 million people each year, and if no action is taken, this number will increase to 8 million by 2030, with 80% of these deaths occurring in low- and middle-income countries. According to statistics released by the Chinese Center for Disease Control and Prevention (CDC), there are more than 300 million smokers in China, accounting for nearly one-third of the world’s total smoking population, and one person dies of a tobacco-related disease approximately every 30 seconds. If tobacco use does not decline, by 2050, the number of tobacco-related deaths in China will rise to 3 million per year. II. The Harms of Tobacco Public awareness of the harms of smoking and secondhand smoke exposure is seriously lacking; more than 3/4 of Chinese people cannot fully understand the health hazards of smoking, and more than 2/3 of Chinese people do not understand the harms of secondhand smoke exposure. Most of the public lacks awareness of the erroneous view that “low tar equals low harm,” reflecting a serious misunderstanding of the issue among the public in general. The lack of public awareness of the health hazards of smoking and the prevalence of misconceptions is one of the most important factors hindering tobacco control efforts in China.
