More than 600,000 people die each year from various diseases caused by second-hand cigarette smoke, according to a recent report by the World Health Organization.
"Some 30 percent of lung cancer patients in Korea are non-smokers, and passive smoking is being blamed," said Paek Yu-jin of Hallym University Medical Center.
"Passive smoking causes not only lung cancer but heart attacks, asthma and many more diseases."
The government has banned smoking in all public facilities, but damage from passive smoking continues.
A study of 1,000 people in Seoul in 2013 showed eight out of 10 people being exposed to secondhand smoke at least once a day.
"To minimize damage caused by secondhand smoke, people should avoid exposure and ventilate rooms often," Paek said.
