Just 30 minutes in a smoky room can cause profound blood vessel injury in healthy young adults, greatly increasing the risk of cardiovascular disease, according to a new study published in the May 6 issue of the Journal of the American College of Cardiology.
The findings add to the growing body of evidence that suggests that there is no risk-free level of secondhand smoke. Secondhand smoke, also called environmental tobacco smoke, contains an array of harmful chemicals, including nicotine, which have been shown to increase one’s risk for cardiovascular disease. Exposure to such smoke causes upwards of 50,000 heart disease deaths in adult nonsmokers every year in the United States, making it a major public health concern.
