The health hazards associated with cigarette smoking are well known. These include lung disease, cardiovascular disease, and cancer. [...] Studies have been investigating whether e-cigarettes can help people who smoke to quit traditional cigarettes. Most of these studies have focused on smokers who were already planning to quit. But those with no plans to quit smoking tend to smoke more cigarettes per day and often have the highest risk for poor health outcomes from smoking.

A team of researchers led by Drs. Karin Kasza and Andrew Hyland [...] has been examining data collected between 2014 and 2019 in the Population Assessment of Tobacco and Health (PATH) study.
