LOUISVILLE, Ky (WDRB) -- "There's no second hand smoke and that's what I love most about it," said Patrick Kullman, who used to smoke a pack of cigarettes every day.
"Then it got to the point where I'd smoke 2 cigarettes a day and now I might smoke one cigarette in the morning when I first wake up," he said.
Kullman told WDRB he's turned to e cigarettes instead.
"There's no coughing. There's no odor on your skin when you're walking back in from work, you don't smell like a cigarette butt," he said.
"When people realized, oh there's an alternative where I can just have nicotine and not the other chemicals that are in traditional cigarettes, I lose my tar and other chemicals, that's when people made the decision, hey we'll try it," said Mike Kimzey, owner of Discount Smokes on Preston Highway in Louisville.
He says e cigarettes keep getting more and more popular.
"It's caused me to have to hire an extra person just to do that," said Kimzey.
Electronic cigarettes are battery-operated. Here's how they work: an atomizer heats a liquid containing nicotine, turning it into a vapor that can be inhaled so there's no smoke cloud.
"I like the fact that I can smoke them indoors. I love that. And I have a child at home and no one wants to smoke a cigarette with a child in the house," said Kullman.
There seems to be several advantages but there are also reports of them starting fires and getting into the hands of children but Kimzey says if everyone follows the directions and uses regulated ingredients, they're perfectly safe.
"There's those guys that are making liquid in their basements or the back of their stores and that's something that's going to hurt the industry," said Kimzey.
However, Kimzey doesn't believe electronic cigarettes will ever replace cigarettes completely.
Manufacturers claim e cigarettes are safe. However, the FDA has questioned their safety.
