Millions at risk of exposure to secondhand smoke in airports: “As the nation approaches Thanksgiving, the busiest travel season of the year, a new CDC report shows that 22 percent of U.S. passenger boardings take place at seven of the largest airports that still allow smoking indoors, putting air travelers and workers at risk of being exposed to secondhand smoke. Studies have shown that exposure to secondhand smoke can cause heart attacks, lung cancer, asthma attacks, and other diseases. The study, published in this week’s MMWR, compares the status of smoke-free polices among the largest U.S. airports in 2002 and 2010. Although more airports prohibit smoking today than in 2002, smoking is still allowed inside seven of the nation’s largest airports, including three of the five busiest airports—Hartsfield-Jackson Atlanta International Airport, Dallas Fort Worth International Airport, and Denver International Airport. Other airports that still allow smoking indoors include: Las Vegas McCarran International Airport, Charlotte Douglas International Airport, Washington Dulles International Airport, and Salt Lake City International Airport.”
