How E-Cigarettes Work
They look like the real thing. The end glows as you inhale. As you exhale, you puff out a cloud of what looks like smoke. It’s vapor, similar to the fog you might see at rock shows, says M. Brad Drummond, MD. He’s an assistant professor of medicine at Johns Hopkins University School of Medicine.
All e-cigarettes work basically the same way. Inside, there’s a battery, a heating element, and a cartridge that holds nicotine and other liquids and flavorings. Features and costs vary. Some are disposable. Others have a rechargeable battery and refillable cartridges.
Using an e-cigarette is called “vaping.”
Are They Safe?
The nicotine inside the cartridges is addictive. When you stop using it, you can get withdrawal symptoms including feeling irritable, depressed, restless and anxious. It can be dangerous for people with heart problems. It may also harm your arteries over time.
So far, evidence suggests that e-cigarettes may be safer than regular cigarettes. The biggest danger from tobacco is the smoke, and e-cigarettes don’t burn. Tests show the levels of dangerous chemicals they give off are a fraction of what you’d get from a real cigarette. But what’s in them can vary.
“E-cigarettes may be less harmful than cigarettes,” Drummond says. “But we still don’t know enough about their long-term risks or the effects of secondhand exposure.”
Pro and Con
E-cigarettes have triggered a fierce debate among health experts who share the same goal — reducing the disease and death caused by tobacco. But they disagree about whether e-cigarettes make the problem better or worse.

Electronic cigarettes, also known as e-cigarettes, are battery-operated products that deliver nicotine, flavor and other chemicals. They turn nicotine, which is highly addictive, and other chemicals into a vapor that is inhaled by the user. Most e-cigarettes are manufactured to look like conventional cigarettes, cigars or pipes. Some people believe that e-cigarettes are safer than traditional cigarettes, but their safety has not been fully studied. People who currently use e-cigarettes have no way of knowing how much nicotine or other potentially harmful chemicals they are inhaling.

A dangerous new form of a powerful stimulant is hitting markets nationwide, for sale by the vial, the gallon and even the barrel.
The drug is nicotine, in its potent, liquid form — extracted from tobacco and tinctured with a cocktail of flavorings, colorings and assorted chemicals to feed the fast-growing electronic cigarette industry.
These “e-liquids,” the key ingredients in e-cigarettes, are powerful neurotoxins. Tiny amounts, whether ingested or absorbed through the skin, can cause vomiting and seizures and even be lethal. A teaspoon of even highly diluted e-liquid can kill a small child.
But, like e-cigarettes, e-liquids are not regulated by federal authorities. They are mixed on factory floors and in the back rooms of shops, and sold legally in stores and online in small bottles that are kept casually around the house for regular refilling of e-cigarettes.
Evidence of the potential dangers is already emerging. Toxicologists warn that e-liquids pose a significant risk to public health, particularly to children, who may be drawn to their bright colors and fragrant flavorings like cherry, chocolate and bubble gum.
