To further the Society’s mission of creating a safer and healthier world, I am pleased to share this information recognizing May 31 as World No Tobacco Day on behalf of the World Health Organization (WHO).

Every year, on May 31, the World Health Organization (WHO) and global partners celebrate World No Tobacco Day (WNTD). The annual 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.
The focus of World No Tobacco Day 2019 is on “tobacco and lung health.” The campaign will increase awareness on:
- the negative impact that tobacco has on people’s lung health, from cancer to chronic respiratory disease,
- the fundamental role lungs play for the health and well-being of all people.
The campaign also serves as a call to action, advocating for effective policies to reduce tobacco consumption and engaging stakeholders across multiple sectors in the fight for tobacco control.
How Tobacco Endangers the Lung Health of People Worldwide
World No Tobacco Day 2019 will focus on the multiple ways that exposure to tobacco affects the health of people’s lungs worldwide.
Lung cancer. Tobacco smoking is the primary cause for lung cancer, responsible for over two-thirds of lung cancer deaths globally. Second-hand smoke exposure at home or in the workplace also increases risk of lung cancer. Quitting smoking can reduce the risk of lung cancer: after 10 years of quitting smoking, risk of lung cancer falls to about half that of a smoker.
Chronic respiratory disease. Tobacco smoking is the leading cause of chronic obstructive pulmonary disease (COPD), a condition where the build-up of pus-filled mucus in the lungs results in a painful cough and agonizing breathing difficulties. The risk of developing COPD is particularly high among individuals who start smoking at a young age, as tobacco smoke significantly slows lung development. Tobacco also exacerbates asthma, which restricts activity and contributes to disability. Early smoking cessation is the most effective treatment for slowing the progression of COPD and improving asthma symptoms.
Across the life course. Infants exposed in utero to tobacco smoke toxins, through maternal smoking or maternal exposure to second-hand smoke, frequently experience reduced lung growth and function. Young children exposed to second-hand smoke are at risk of the onset and exacerbation of asthma, pneumonia, and bronchitis, and frequent lower respiratory infections.
Globally, an estimated 165,000 children die before the age of five of lower respiratory infections caused by second-hand smoke. Those who live on into adulthood continue to suffer the health consequences of second-hand smoke exposure, as frequent lower respiratory infections in early childhood significantly increase risk of developing COPD in adulthood.
Tuberculosis. Tuberculosis (TB) damages the lungs and reduces lung function, which is further exacerbated by tobacco smoking. The chemical components of tobacco smoke can trigger latent infections of TB, which around a quarter of all people are infected with. Active TB, compounded by the damaging lung health effects of tobacco smoking, substantially increases risk of disability and death from respiratory failure.
Air pollution. Tobacco smoke is a very dangerous form of indoor air pollution: it contains over 7,000 chemicals, 69 of which are known to cause cancer. Though smoke may be invisible and odorless, it can linger in the air for up to five hours, putting those exposed at risk of lung cancer, chronic respiratory diseases, and reduced lung function.
Goals of the World No Tobacco Day 2019 Campaign
The most effective measure to improve lung health is to reduce tobacco use and second-hand smoke exposure. But knowledge among large sections of the general public, and particularly among smokers, on the implications for the health of people’s lungs from tobacco smoking and second-hand smoke exposure is low in some countries. Despite strong evidence of the harms of tobacco on lung health, the potential of tobacco control for improving lung health remains underestimated.
The World No Tobacco Day 2019 campaign will raise awareness on the:
- risks posed by tobacco smoking and second-hand smoke exposure;
- awareness on the particular dangers of tobacco smoking to lung health;
- magnitude of death and illness globally from lung diseases caused by tobacco, including chronic respiratory diseases and lung cancer;
- emerging evidence on the link between tobacco smoking and tuberculosis deaths;
- implications of second-hand exposure for lung health of people across age groups;
- importance of lung health to achieving overall health and well-being;
- feasible actions and measures that key audiences, including the public and governments, can take to reduce the risks to lung health posed by tobacco.
The cross-cutting theme of tobacco and lung health has implications for other global processes, such as international efforts to control noncommunicable diseases (NCDs), TB, and air pollution for promoting health. It serves as an opportunity to engage stakeholders across sectors and empower countries to strengthen the implementation of the proven MPOWER tobacco control measures contained in the WHO Framework Convention for Tobacco Control (WHO FCTC).
Call to Action
Lung health is not achieved merely through the absence of disease, and tobacco smoke has major implications for the lung health of smokers and nonsmokers globally.
In order to achieve the Sustainable Development Goal (SDG) target of a one-third reduction in NCD premature mortality by 2030, tobacco control must be a priority for governments and communities worldwide. Currently, the world is not on track to meeting this target.
Countries should respond to the tobacco epidemic through full implementation of the WHO FCTC and by adopting the MPOWER measures at the highest level of achievement, which involves developing, implementing, and enforcing the most effective tobacco control policies aimed at reducing the demand for tobacco.
Parents and other members of the community should also take measures to promote their own health, and that of their children, by protecting them from the harms caused by tobacco.
