May,07,2022

  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.


What‘s the bottom line?

  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, and pregnant women, as well as 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.


What are e-cigarettes?

  E-cigarettes come in many shapes and sizes. Most have a battery, a heating element, and a place to hold a liquid.

E-cigarettes produce an aerosol by heating a liquid that usually contains nicotine—the addictive drug in regular cigarettes, cigars, and other tobacco products—flavorings, and other chemicals that help to make the aerosol. Users inhale this aerosol into their lungs. Bystanders can also breathe in this aerosol when the user exhales into the air.

E-cigarettes are known by many different names. They are sometimes called “e-cigs,” “e-hookahs,” “mods,” “vape pens,” “vapes,” “tank systems,” and “electronic nicotine delivery systems (ENDS).”

Some e-cigarettes are made to look like regular cigarettes, cigars, or pipes. Some resemble pens, USB sticks, and other everyday items. Larger devices such as tank systems, or “mods,” do not resemble other tobacco products.

Using an e-cigarette is sometimes called “vaping.”

E-cigarettes can be used to deliver marijuana and other drugs.
