Electronic cigarettes are also known as e-cigarettes.
Electronic cigarettes are battery-operated devices that deliver nicotine with flavorings and other chemicals to the lungs in vapor instead of smoke.
E-cigarettes contain a cartridge of liquid containing nicotine, flavors and other chemicals.
The device heats up the liquid without burning it, creating a vapor that is inhaled.
They've recently gained in popularity due to their convenience & the variety of flavors available, but are they really safe?
Some proponents say that because there is no combustion & no secondhand smoke, e-cigarettes produce fewer carcinogens than regular cigarettes.
But critics say not enough research has been done on the effects of long-term use or potential health risks associated with these products.
Recent study has found that electronic cigarettes contain harmful chemicals that can potentially damage the lungs.
Another study has found a potential link between electronic cigarettes and cancer.
Is vaping safe, then?
We don't yet know for sure.
While e-cigarettes don't produce tar or carbon monoxide, two of the most harmful components of tobacco smoke.
They do contain other potentially harmful chemicals, including metals like nickel and lead.
