Nearly half (46 percent) of the world’s busiest airports have smoke-free policies, according to a new, first-of-its-kind study by the Centers for Disease Control and Prevention (CDC).

According to the CDC’s first assessment of smoke-free policies in the world’s airports, which has just been published in the Morbidity and Mortality Weekly Report (MMWR), 23 of the world’s 50 busiest airports have smoke-free indoor policies. The other 27 allow smoking in designated or ventilated indoor areas.

Airports were defined as having a smoke-free policy if they completely prohibited smoking in all indoor areas. The 27 airports defined as having no smoke-free policy allowed smoking in designated smoking rooms, restaurants, bars, or airline clubs.

"The Surgeon General has concluded there is no risk-free level of secondhand smoke exposure‎," said Corinne Graffunder, D.Ph., M.P.H., director of CDC's Office on Smoking and Health, in a written release. "Even brief exposure can have health consequences."

The study, which assessed policies in 2017, found significant variations in smoke-free policy status by region. In North America, 78 percent (14 of 18) of the busiest airports have a smoke-free policy; in Europe, 44 percent (4 of 9); in Asia, 18 percent (4 of 22). All four of the Asian airports with a smoke-free policy are in China.

A previous CDC study documented that secondhand smoke can transfer from designated smoking areas into nonsmoking areas in airports, where nonsmoking travelers and employees can be exposed. As a result, travelers and workers are at risk of secondhand smoke exposure in these airports.

"Separating smokers from nonsmokers, cleaning the air, and ventilating buildings cannot eliminate exposure of nonsmokers to secondhand smoke," said Brian King, Ph.D., Deputy Director for Research Translation in the Office on Smoking and Health. "People who spend time in, pass by, clean, or work near these rooms are at risk of exposure to secondhand smoke."

Secondhand smoke causes an estimated 34,000 heart disease deaths and 7,300 lung cancer deaths each year in the United States. Exposure to secondhand smoke from burning tobacco products causes premature death and disease including coronary heart disease, stroke, and lung cancer among nonsmoking adults. In children, it can cause sudden infant death syndrome, acute respiratory infections, middle ear disease, exacerbated asthma, respiratory symptoms, and decreased lung function.
