One thing that is known about electronic cigarettes: they've become a serious business in the United States.
Although e-cigarettes represent only a tiny percentage of the U.S. tobacco market, the industry is growing.
The number of people currently “vaping” has increased substantially over the last few years, with sales of nearly $2 billion in 2013.
Some analysts predict that this could grow to $10 billion by 2017 and eventually overtake sales of conventional cigarettes. It's worth noting that the industry is maturing without much in the way of oversight or regulation.
