I see regulations being put in place on things that need regulating, such as the way batteries that us vapers use, and the way that ejuice is made and under what guidelines but a ban? nah.
The issue is, what would they ban? Ecigs (the blue brand type), the e liquid, the batteriess, the mods, the tanks, all individually? Even Ebay cant keep vaporizer parts off their site because technically they are in the correct category even though they list them as tobacco products which are not allowed. Check it out.

Vaping (what you do once you get past using simple ecigs) is something that a lot of people are getting behind and standing up for, if you thought pot heads were creative wait till they see what happens if the government tries to ban the use, sale, and purchase of vaporizers and juices.
Now, high taxes on the little ecigs and ejuice that contain nicotine, I can definitely see that happening in the U.S.
Lol one example of how to get creative and make your own juice using stuff purchased from Wal-Mart
Oh and once people cut out the nicotine completely, they can just shop at a site or store that supplies the food industry, such as http://www.candyflavor.com/PG_Based_Candy_Flavor.html
