Get the facts about electronic cigarettes, their health effects and the risks of using e-cigarettes.
E-cigarettes are sometimes called “e-cigs,” “vapes,” “e-hookahs,” “vape pens,” and “electronic nicotine delivery systems (ENDS).” Some e-cigarettes look like regular cigarettes, cigars, or pipes. Some look like USB flash drives, pens, and other everyday items.
E-cigarettes have the potential to benefit adult smokers who are not pregnant if used as a complete substitute for regular cigarettes and other smoked tobacco products.
E-cigarettes are not safe for youth, young adults, pregnant women, or adults who do not currently use tobacco products.
While e-cigarettes have the potential to benefit some people and harm others, scientists still have a lot to learn about whether e-cigarettes are effective for quitting smoking.
If you’ve never smoked or used other tobacco products or e-cigarettes, don’t start.
Additional research can help understand long-term health effects.
