Electronic cigarettes are becoming increasingly popular, but little is known about the risks they pose to cardiovascular health. New research investigates the link between habitual electronic cigarette use and cardiovascular risk.
More and more people use electronic cigarettes (e-cigarettes) instead of conventional ones, as the former are perceived to be safer. E-cigarettes do not contain tobacco and do not involve combustion.
E-cigarettes were first introduced in 2006 in the United States. Since then, they have become particularly popular among teens. The number of teenagers who vape increased fourfold between 2011 and 2015.
However, e-cigarettes still contain the addictive nicotine and some of the chemicals found in regular cigarettes. In 2009, the U.S. Food and Drug Administration (FDA) warned that e-cigarettes contain "detectable levels of known carcinogens and toxic chemicals to which users could be exposed."
New research examines the link between regular e-cigarette use and the implications for cardiovascular risk.
