EAST TEXAS (KYTX) -- Millions of Americans have used electronic cigarettes. Advocates say they're a safe and effective alternative to cigarettes, but as Susan McGinnis reports, the Food and Drug Administration says e-cigarettes may be hazardous to your health.
Justin King enjoys a puff on his lunch break. But he's not smoking regular cigarettes anymore. He's using electronic cigarettes which he says helped kick his 18-year addiction.
"I wasn't feeling good, I was overweight, I was smoking two packs of cigarettes a day," he said.
E-Cigarettes are battery operated device; some of which turn nicotine into a vapor that is inhaled instead of smoke.
A recent study in Italy found e-cigarettes helped smokers cut the number of cigarettes they smoked in half. And many kicked the habit completely.
"I think it could be a revolutionary tool from a public health perspective."
But not everyone is convinced. Some groups say more research is needed on the potential risks of e-cigarettes.
"Concerned they contain chemicals that are toxic and could cause cancer," American Lung Association's Erika Sward. "You just should not inhale something into your lungs until it's proven to be safe."
Hundreds of websites sell e-cigarettes with a variety of flavor cartridges - groups like the American Lung Association are also worried they could be addictive or serve as a gateway to other tobacco products.
They want the FDA to regulate them.
"So that we can first of all understand what consumers are inhaling when they use these products, what the impact on health is," Sward said.
Manufacturers insist e-cigarettes are a healthy alternative to smoking without the health risks.
For King, it was an easy choice.
"I think it saved my life," he said.
This former smoker says e-cigarettes have helped him breathe easier.

The FDA says it intends to propose a regulation so the agency can regulate e-cigarettes the way it does other tobacco products.
