Smoke from e-cigarettes has been reconfirmed to cause health deterioration in both smokers and those exposed to secondhand smoke, as well as air pollution. Contrary to the perception that e-cigarettes are less harmful than conventional cigarettes, research indicates they affect not only vascular endothelial cells but also deep areas of the brain, and can even cause thirdhand smoke exposure.
Professor Byun Min-kwang of the Division of Pulmonology at Gangnam Severance Hospital announced Wednesday that his team, in collaboration with researchers from Ohio State University College of Medicine and UC San Diego School of Medicine, conducted a comprehensive analysis of approximately 140 key studies from the past 20 years proving the harmfulness of e-cigarettes, demonstrating the dangers of e-cigarettes that had been considered relatively minor compared to conventional cigarettes.
