Growing in popularity, electronic cigarettes are the new craze among smokers.
"It's like going from an analog tape, to a CD, to Pandora," Torrie Atchison of Smoking Vapor said.
Many people use them to quit smoking traditional cigarettes.
"I smoked for 22 years, and I haven't smoked a cigarette in two months because of this product,"
"They are marketing it as a safe alternative to smoking, but that has yet to be proven," Dr. Brian Williams said.
Atchison says that the e-cigs have less chemicals than the alternative.
"The traditional cigarette has about 4,000 chemicals in it, e-cigarettes have four," Atchison said.
Doctor Williams says that since they aren't regulated by the FDA yet, there is no way to prove that.
"These have just came onto the market, so as I said, they're not regulated. We don't know what other chemicals are in them," Dr. Williams said.
Some non-users worry about second hand smoke.
"Again the companies that are marketing this and selling this, have yet to prove that there is no second hand related inhalation of those chemicals," Dr. Williams said.
"Since it's water vapor, there's no actual smoke. It's not going to affect someone's health," Atchison said.
Atchison says that they are not only healthier, but cost effective, too.
"I smoked a pack to a pack and a half a day. So, if you add that up, it's like $180 to $200 dollars a month," Atchison said. "With these, after my initial costs, I spend $32 dollars a month."
BUT, Dr. Willams says that since they are so new, there are no studies done for long term usage.
:"One would think it might be safer, but if you've never smoked and you pick this up... Why take the risk? If you're a current smoker, maybe it is better. I'm not sure," Dr. Williams said.
