Electronic Cigarettes? Does it feel like the real one? 
how is it possible if we take puffs of this electronic cigarette it will not create cancer in our lungs 
because have no tar and tobacco in it and no cough while smoke it . then how it feels like the real one .I'm highly doubting that, the two main ingredients to ecig juice.. 1 is a major food additive, and used in hospital air vents to sterilize the air, and the other is the mist you see come out of asthma inhalers. And of course nicotine if you chose so.
That being said I'm highly doubting someone got cancer in the two year window where anyone even knows what an ecig is.
