Tobacco use continues to be the leading cause of preventable disease and death in the United States. There are no safe tobacco products; however, the health risks for tobacco products exist on a continuum, with combustible products such as cigarettes being the most harmful. Decades of research have documented that cigarette smoking harms nearly every organ of the body; cigarette smoke contains nearly 7,000 chemicals, approximately 70 of which cause cancer1.

Non-combustible tobacco products, such as e-cigarettes, generally have lower health risks to the user than combusted tobacco products. The US National Academies of Sciences, Engineering, and Medicine (NASEM) found conclusive evidence that switching completely from cigarettes to e-cigarettes reduces a person’s exposure to many toxicants and carcinogens that are present in combusted tobacco cigarettes1.
