E-cigarettes are battery-powered devices that have cartridges or refillable tanks that contain a liquid mixture primarily comprised of propylene glycol and/or glycerol and nicotine, as well as flavorings and other chemicals.2 They emulate conventional cigarettes, but the exhaled aerosol does not contain smoke or most of the assorted chemicals found in cigarettes and studies of specific types of e-cigarettes have shown that they produce less air toxins compared with regular cigarettes.
E-cigarettes are mostly unregulated and their health effects are not fully known, especially when associated with long-term use.
The rise of the manufacturing and marketing of e-cigarettes has had a particular influence on U.S. youth, and is becoming a problem for schools. For more in this story, CLICK HERE.
The AHA advocates for including e-cigarettes in smoke free laws, as well as including them in laws that prohibit the sale and marketing of tobacco products to minors. The AHA also advocates for further research and surveillance on the short, medium, and long-term physiological effects of e-cigarette nicotine, propylene glycol and glycerol, flavorings and other ingredients, and we advocate for including e-cigarettes in the definition of tobacco products for legislation and regulation.
