How do they compare?
E-cigarettes use heat from a battery to produce a vapor from a flavored liquid that contains nicotine. Users simulate the effect of smoking by inhaling the vapor, a practice known as “vaping.” Long-term health effects are unknown.
Cigarettes, on the other hand, are currently the No. 1 preventable cause of death in the United States.
“Traditional cigarettes are made of tobacco, which, when combusted, will produce more than 6,000 chemicals, many of which are known to cause cancer,” says pulmonologist Umur Hatipoglu, MD. Traditional cigarettes contain substances such as formaldehyde, arsenic, tar and ammonia, which are established hazards to lung health.
There are fewer chemicals in e-cigarettes (though still as many as 250 or more). They’re not regulated by the U.S. Food and Drug Administration (FDA), though, so you have no way of knowing what, exactly, is in them.
