[Research estimates that second-hand smoke will cause nearly 1.7 million deaths worldwide in 2023] On September 16, an international scientific research team led by scientists from the University of Washington in the United States published a study in the latest issue of "The Lancet Public Health" magazine, saying that more than 2.7 billion people around the world will be exposed to second-hand smoke in 2023, including as many as 767 million children aged 0-14 years old, resulting in nearly 1.7 million deaths. The study said that tobacco remains one of the main drivers of global disease, with an estimated 8 million people dying from smoking-related diseases in 2023, many of whom are non-smokers exposed to second-hand smoke. It is estimated that this exposure is responsible for nearly 1.7 million premature deaths and contributes to a host of premature disabilities and illnesses from ischemic heart disease. Ischemic heart disease is a disease that occurs due to insufficient oxygen supply to the heart muscle. The report emphasizes that secondhand smoke exposure is a globally recognized health risk and that there is no "safe inhalation level." (Science and Technology Daily)
