Electronic cigarettes are gaining popularity and catching the attention of smokers, but just because they're not real doesn't mean they're not harmful.
An e-cigarette gives smokers an alternative to traditional tobacco cigarettes.
They take out all the harmful chemicals but it still contains the addictive part of cigarettes.
When it comes to cost the e-cigarette is less expensive and a five pack of cartridges has as much nicotine as ten regular packs.
The "e-cigs" do let off a vapor but it's not harmful and there's no worry of second hand smoke.
